Humans have suffered from heartburn for all of history prednisolone syndrome death . Hippocrates warned in 400 BC that eating cheese after a full meal could cause indigestion, especially if accompanied by wine propecia finasteride 5mg .”O Centuries ago, doctors called it dyspepsia, from Greek words meaning difficult to digest propranolol package insert .

HEARTBURN OR HEART ATTACK?
WIhIngh heartburn is rarely considered a life-threatening condition, there are times when vague upper gastrointestinal tract symptoms indicate a heart attack in progress liquid dostinex . This may be especially true for women, who do not always
experience “classic” heart attack discomfort canon nb-2lh lithium rechargeable battery . If you have any reason to suspect you’re having a heart attack, call 911 and hightail it to the hospital norvasc hot flashes .
Lazy LES
The real cause of heartburn is a lazy muscle at the end of the esophagus (food tube), just above the stomach lithium minning company . Normally, food is chewed, swallowed, and pushed into the stomach past a one-way valve called the lower esophageal sphincter (LES) does penicillin treat candidiasis . This muscular sphincter is not supposed to let food or gastric juice (which contains hydrochloric acid and digestive enzymes) back up into the esophagus, where it does not belong zebeta dosage .

For reasons that are not completely understood, this muscle can lose its contractility and allow reflux to occur lipitor confusion . Many medications, including diazepam (Valium), nitroglycerin, and progesterone, may contribute to LES laziness toradol shelf life .
Food Fight
People are frequently given lots of advice about what not to eat to avoid heartburn generic of omnicef . Dietary dogma has it that fatty food is bad news cialis canadian geneic . Cheese, for example, is considered a major problem, just as Hippocrates suggested back around 400 BC pepcid rebate coupons . The trouble is, there just haven’t been any good studies to prove that fatty foods should be forbidden estradiol levels during fet cycle . Investigators who actually performed a study to determine if a high-fat meal was a culprit came up empty:3K
In summary, our study did not provide evidence for an increase in gastro-oesophageal reflux after fatty foods, at least for the first 3 postprandial [after eating> hours, suggesting that the relationship between fat and induction of heartburn in reflux disease is more complex than commag(y thought celebrex drug elderly program .~~6

So fatty foods may not really be as bad as everyone thought, at least in terms of heartburn bacterial overgrowth and metronidazole . Doctors have long believed that many other foods can also make the LESrelax and contrib- ute to GERD boniva lawsuit uveitis . But a thoughtful review of the medical literature now calls this belief into question levaquin problems . People suffering from heartburn have been warned to avoid spicy foods, citrus fruits, chocolate, mint, coffee, tea, and alcohol rimonabant fda report . There is, however, little scientific evidence that avoiding these foods and beverages reduces reflux cilostazol 50mg .384 If you find that mint or coffee causes you distress, by all means avoid it claritin and benadryl . If it doesn’t bother you, relax and enjoy it prednisone sedation danger . Each person is different, so you may have to keep a food diary and a record of your symptoms to identify your particular nemesis fluoxetine long term side effects .
Despite the lack of solid scientific evidence, many people maintain that highly acidic foods make them uncomfortable zoloft and pain medication . Things like coffee, tomatoes, citrus juices, colas, sauerkraut, and wine may produce irritation of the stomach and esophagus as well as urinary tract discomfort caffeine and rum . Not surprisingly, many folks give up some of their favorite foods because of the unpleasant consequences loratadine claritin safe during pregnancy .

In addition, it may help relieve bladder symptoms associated with acidic foods intas strattera for sale online . Losing weight may also be important in preventing reflux scleroderma and clindamycin .
Although most physicians warn against -fatty foods, they rarely mention carbohydrates singulair in the news . But we have heard from many readers that a typical American high-carb diet can also cause gastric grief treating anxiety attack with wellbutrin .
Years ago, I was overweight and had high blood pressure citalopram hydrobromide effects and side effects . So my doctor put me on a diet is tramadol a opiet .

We do not think this reader was imagining things finasteride ringing effects . Many people have told us that when they go on an Atkins- or South Beach—type diet their heartburn disappears actos drug . If you search the medical literature, you will discover that as far back as 1972 researchers reported that a low-carb diet was far superior to a “gastric” diet for heartburn relief traumatic brain injury baclofen .385 In those days a gastric diet was likely bland: low in fat, low in acid, and restricted in coffee and alcohol xlpharmacy fexofenadine 60mg .

Treating Heartburn
The saying goes that when all you have is a hammer, every-
thing looks like a nail breastmilk procardia . Drug companies have been very good at developing acid-suppressing drugs, so they have decided that heartburn is a disease of excess acid terbinafine symptoms . Never mind that stomach acid is important in digesting food and serving as a barrier against bacterial infection boniva and complications .
There’s another thing drug companies don’t mention does aleve cause facial swelling . Acid is not the only irritating chemical in your stomach prednisolone adverse reactions . Gastric juice contains a witches’ brew of compounds ultram product information . A digestive enzyme called pepsin can be irritating to delicate tissue in the esophagus no overnight prescription soma . Bile acids that aid in digestion get into the esophagus during reflux and can also be quite irritating colorado imitrex website .388 And bacteria that flourish in the stomach during acid suppression may create carcinogenic chemicals such as nitrosamines and acetaldehyde loratadine and pregnancy .389
Since we don’t have drugs to neutralize these chemicals, they continue to allpel the esophagus during reflux remeron hypertension . Because You may not “feel” these pasties the way you feel acid, they are left to silently do damage during usual drug treatment tramadol cod florida . If the real goal, however, is to keep all these irritating contents of the stomach out of the esophagus, perhaps there are some other tricks to try clomid multilple births .
There used to be an interesting drug called cisapride (Propulsid) mycin ending antibiotics antibiotics . It worked reasonably well to increase the strength of
the lower esophageal sphincter tetracyclines antibiotics . In addition, the drug helped the stomach empty dose doxycycline lyme disease dogs . These two actions made cisapride a logical choice to fight reflux by keeping stomach contents out of the esophagus generic bupropion side effect . Unfortunately, this medicine had a fatal flaw rosiglitazone arrhythmia . It could occasionally cause life-threatening heart rhythms (torsades de pointes), especially when taken with certain other medications weight gain paroxetine . Because the FDA was unsuccessful at keeping physicians and pharmacists from prescribing and dispensing incompatible drugs with cisapride, the feds decided that this heartburn drug needed to be removed from the market active ingredient sildenafil citrate .
Another medicine with a somewhat similar effect that has been prescribed for reflux is metoclopramide (Reglan) hoodia lipitor drug interaction . Unfortunately, it also has some nasty side effects, including drowsiness, dizziness, mental depression, suicidal thoughts, confusion, fatigue, insomnia, headache, hallucinations, and involuntary muscle movements that may sometimes be irreversible greek coffee caffeine heart problems . Not surprisingly, Reglan is not one of our favorite drugs rash wont heal diflucan .
There is a new prescription heartburn medication that we are quite excited about, though subaction showcomments cialis thanks remember . At the time of this writing it has not been approved for sale in the United States, but it is very popular in Japan and India zyprexa psycotic reactions . Itopride (sold in India as Itoz) appears to be quite effective against symptoms of indigestion (bloating, nausea, fullness, and pain) as well as heart-
burn generic wellbutrin xl anti-depressent . 390 lansoprazole side effects back pain . 91
We are intrigued by this drug because it is a “prokinetic” agent dogs skin darkening prednisone . That means it speeds emptying of food from the stomach and may also enhance muscle tone in the esophagus, helping clear out acid and preventing it from splashing back sprinkles prevacid . It may turn out to be especially beneficial for diabetics, who often have difficulty with “gastric emptying using viagra after prostate surgery .” Unlike cisapride, itopride does not appear to cause irregular heart rhythms lou gehrig’s and lipitor . Other side effects are relatively rare, and the drug appears to be well tolerated rx plan for altace .
Soothing Heartburn with Saliva
One of the cheapest and most effective remedies for heartburn is produced by our own bodies cetirizine hydrochloride side effect . It is as simple as spit psychogenic polydipsia and prevacid . We stumbled across this approach in 1984, when researchers reported in the New England Journal of Medicine that “residual acid [in the esophagus> is neutralized by swallowed saliva norvasc buy .”39′ Not only does saliva buffer acid, swallowing also increased the muscular contractions of the esophagus, moving acid (and other unpleasantness) back into the stomach where it belongs cheap nolvadex online cheap .
Scientists have looked for easy ways to increase saliva production cellcept suppliers . What they came up with is as simple as chewing sugarless gum bedroom withdraw from lexapro .93-34 More important, however, is whether chewing gum can relieve heartburn pfizer lipitor atorvastatin . British researchers discovered that chewing gum could double the flow of saliva and shorten the amount of time the lower esophagus is bathed in acid a trusted site to buy prozac .They concluded that “chewing gum might be a non-pharmacological treatment option for some patients with symptomatic gastro-oesophageal reflux wellbutrin work .”395
Yeah! I finally found out why my “home remedy” works prednisone without prescription .
I’m a nurse and have often given chewing gum to a patient who complains of indigestion allergic reaction to claritin . I’d tell them this helps me amoxicillin dosage 500 mg . It often seemed to help them price of pentasa . Now you’ve told me what’s behind it—thanks!
Another group of researchers asked patients who suffered from symptoms of heartburn to chew sugarless gum (Orbit) for 30 minutes after eating a high-fat meal prednisone central obesity . They found that acid was washed out of the lower esophagus much more quickly when people chewed gum ractions ziac zocoor . TWo-thirds of these patients had significant improvement in their heartburn symptoms zocor versus vitamin d . The researchers concluded that “the use of chewing gum with other conservative measures could provide a comparatively safe and effective method of controlling acid reflux and SyMptorriS naltrexone multiple sclerosis .,,396
Most people do not know about this incredibly easy and inexpensive remedy because there are no TV commercials promoting the benefits of a pack of gum against heartburn baclofen research . Chewing gum makers cannot advertise this benefit because they would run afoul of the FDA requip and mood disorders . And drug companies certainly have nothing to gain if people use chewing gum instead of high-priced
Saliva
Saliva is free, helps neutralize acid, and washes irritating, stomach contents out of the esophagus and back where they belong buy ranitidine drug . There are no side effects or downsides cialis drug sample viagra .
Ways to stimulate saliva production: chew sugarless gum or suck on lozenges or something sour how lithium .
acid suppressors sulfisoxazole trimethoprim . Doctors may not know about the substantial research supporting this home remedy meloxicam chiens . It may seem wimpy compared to prescribing potent and pricey drugs furosemide breast cancer .
If you walk and chew gum at the same time, you may get a little added benefit side effects of the medication paxil . Investigators found that walking after a study breakfast of bacon, eggs, toast, and coffee helped reduce heartburn symptoms among those with reflux can wellbutrin cause joint pain . Chewing gum for 1 hour, however, worked even better and the effect lasted longer-3 hours compared to 1 hour for walking the testosterone dilema . Although the researchers did not combine the two, we think it might be a very sensible approach to take a walk after eating and chew gum at the same time clozapine registry problems .
Sucking on hard candy also stimulates saliva production ofloxacin generic name . If you really want to liven up your taste buds and create astonishing amounts of saliva, search out the cough lozenges called Fisherman’s Friend very high capacity lithium cell . These lozenges have been made by Loft-house of Fleetwood in Lancashire, England metoclopramide 5 mg side effects . since 1865 (www nexium heart trouble . fishermansfriend zocor free samples .com) hpv zovirax . They are all natural and contain menthol, capsicum (essence of hot peppers), eucalyptus oil, and natural licorice warfarin dark stool . This is an acquired taste, however, and will not be to everyone’s liking all about prozac . Too much licorice for a long time could have negative health consequences risperdal drug facts . We don’t know how much licorice is in Fisherman’s Friend prescription clomiphene . The company also makes a menthol eucalyptus sugar-free chewing gum that might be worth a try prozac used for . serenity natural lithium .
Tea for Tummy Trouble
Anything that washes stomach acid and other digestive juices out of the esophagus is beneficial lyme erythromycin . Sipping tea slowly might be just the ticket, especially if the tea is herbal and has calming properties dangers evista . People have used all sorts of preparations to soothe an upset stomach, including anise seeds, caraway seeds, catnip, lemon balm, licorice, and sage seamus moore viagra song . But our two favorite herbs are chamomile and ginger combining lexapro and st john’s wort . They have been used for cenWfie,S all around the world to relieve indigestion accutane the second time .

Ginger
Chinese healers have used ginger for thousands of years novo trazodone . Studies show that it can relieve symptoms of nausea and vomiting associated with motion sickness generic silagra 238 . It works best if you sip it slowly as a tea or in real ginger ale (Carver’s Original or Blenheim) nolvadex omnadren . Ginger cookies and candied ginger may also do the job zyprexa and aplastic anemia .
Side effects: Allergy is uncommon metronidazole vaginal .
Downside: Those taking blood thinners like warfarin (Coumadin), Plavix, or even aspirin may be more vulnerable to bleeding compazine in pregnancy .
Cost: Approximately $5 to $8 for a month’s supply of ginger tea
After 1 month of adding about 3 tablespoons of the cinnamon-ginger drink to my tea in the morning and at night, my low-density lipoprotein cholesterol levels had dropped 30 points, blood sugar dropped 10 points, and the heartburn was in control tell me about clomid .
This cinnamon-ginger tea has sugar, unfortunately bacteria led to penicillin researchers . A simpler alternative is to add a piece of candied ginger to tea hypersecretion of thyroxine .
The ginger is amazing for heartburn and the Chinese have used it for centuries for motion sickness can you give glyburide without food .
If tea is not your thing, you may want to opt for other forms of ginger advair diskus generic . Readers have shared that candied ginger relieved reflux and “stomach burn” just as well as acid-suppressing drugs piroxicam digemid . And while we cannot endorse eating the Garbs found in cookies, we found this report intriguing: “Since I have had a problem with Prevacid, I tried ginger, both in ginger snaps and as crystallized ginger free samples of zocor . It’s been working like a charm fanta pineapple caffeine .”
Mustard tor Heartburn?
Just about the last thing we would ever consider for heartburn is mustard allegra d 24 mg . It seems like a spicy food would only make matters worse amoxicillin trihydrate . And yet enough people have shared their enthusiasm for mustard that we cannot ignore this odd remedy prescription for macrobid .
My husband and I use a teaspoon of yellow mustard to relieve heartburn flutamide medication . I was in a chat room a while ago when one of the chat-ters complained about her heartburn can you overdose from prozac . Another said, “Try mustard lipitor jarvek .” We all thought this was ludicrous, but she did try it and it helped caffeine pills and college students .
The next time my husband had one of his terrible roll-on-thefloor-in-agony bouts of heartburn, I suggested mustard fed ex tramadol . I figured it couldn’t hurt any more than what he already had is relafen a narcotic . Amazingly, it worked, faster than Turns or DiGel albuterol how long in urine . Our friends have had good results also venlafaxine for dogs .
Some folks are not going to be able to stomach mustard truth about avandia . ‘The spiciness is just too much for them valtrex expiration . But mustard may stimulate saliva and work in a similar manner as chewing gum adderall and abilify . When we checked with one of the world’s leading experts on herbs, James Duke, PhD, he suggested that turmeric, the spice that makes mustard yellow, has ingredients that are beneficial for the digestive tract antabuse implant .

Vinegar
If you think mustard makes no sense for heartburn, then you will think we are totally crazy to mention vinegar robaxin info . After all, drug companies have been promoting antacids and acid-suppressing drugs for decades misoprostol use . Consuming acid (vinegar is acetic acid) would seem like the last thing one would want to do when dealing with heartburn accutane clavaris sotret buy without prescription . Of course, that assumes that acid somehow contributes to reflux raloxifene evista . But if the theory is wrong, then perhaps this remedy might have some merit percocet and robaxin .
A doctor advised a family friend to take a tablespoon of vinegar for heartburn relief I tried 2 teaspoons of apple cider vinegar and it worked interigo keflex . It tastes strong for a few minutes and I thought the heartburn was worse will penicillin react with methadone . Then the pain went away for good do it yourself testosterone booster .
We admit that it sounds strange, but others have shared similar success signs of caffeine withdrawal . We would discourage anyone from sipping pure apple cider vinegar, however canada pharmacies allegra d 24 . It’s just way too strong clindamycin in renal insufficiency . Perhaps diluting it in water would make it easier to swallow accutane infertility . One reader offered something even more bizarre than dilute vinegar wheatgrass vs coumadin .

Theophylline
Theophylline-type drugs are also known as xanthines or methylxanthines. These drugs are chemically similar to caffeine. They cannot be inhaled, so are taken as tablets or syrup. They start working about 30 minutes after being taken and their effects last for 6-8 hours. Slow-release preparations take 90 minutes to start working, but they last 12-24 hours, and are therefore useful for nocturnal asthma.
In Britain, doctors generally regard theophylline-type drugs as reliever drugs (see p. 152), but rather risky ones whose use is only justified for people with severe asthma. They are given, as an additional treatment, to asthmatics who are not responding well to the usual drug programme (see p. 160). Unfortunately, fairly high doses are needed for theophylline-type drugs to act as relievers, i.e. to reverse bronchospasm. There is a very narrow margin between such a dose and one that causes major (and sometimes dangerous) side effects.
Such side effects usually occur when the doctor is still trying to work out the correct dose – this varies from one person to another, so prescribing theophylline-type drugs is no easy matter. Once you are established on a safe dose (and provided your general health and your intake of alcohol, nicotine and medicinal drugs does not vary – see p. 158) you can usually continue taking theophylline without serious side effects.
In the United States, many doctors also give theophyllinetype drugs, at much lower doses, to people with mild asthma. At these low doses they do not act as relievers, but they have a slight anti-inflammatory effect and therefore act as preventers. The risk of toxicity is much less. Taking low doses of theophylline allows people with mild asthma to reduce their use of beta-2 relievers. However, inhaled steroids are usually more effective in this role, and are the preferred treatment outside the United States.
Side effects
Typical side effects include nausea, vomiting, stomach pains, diarrhoea (sometimes with blood), headache, anxiety, restlessness, insomnia, dizziness, and a pounding heart or irregular heartbeat.
Any side effect of these drugs should be taken seriously and reported to your doctor as soon as possible. If you cannot get an appointment quickly, it may be best to stop taking the drug before seeing the doctor, as long as you have other drugs to control your asthma. Call your doctor for advice.
It is remarkably easy to overdose when taking these drugs at higher doses (see p. 157). Such overdoses can be fatal. The symptoms include repeated vomiting, shaking, feeling unusually hot, needing to urinate frequently, severe thirst, maniacal behaviour, and irregular heartbeat (palpitations). Delirium and convulsions may occur shortly afterwards, so get hospital treatment urgently if you have any of these symptoms.
Unfortunately, a serious overdose can sometimes occur in people who have taken theophylline-type drugs without trouble for many years. There may be no advance warning that anything is wrong - no mild side effects preceding the serious ones. To protect yourself against this, you need regular blood tests from your doctor.
One fundamental problem with theophylline-type drugs is that many different factors - including diet, illnesses other than asthma, and taking other drugs - can alter the way your body deals with the drug. If your liver is breaking down the drug more slowly than usual, the amount in your blood will rapidly increase, and can reach toxic levels.
These are steps that can help prevent an overdose with theophylline-type drugs:
• If you start taking a new drug of any kind, or stop taking a drug (especially the contraceptive pill), or if you change your intake of nicotine or alcohol, ask your doctor - preferably in advance - if your dose of theophylline-type drug needs to be changed.
• A great many drugs interact with theophylline-type drugs, including the new anti - leukotriene drugs. You should always be cautious with any new drug, but take particular care with two antibiotics - ciprofloxacin (brand name Ciproxin) and erythromycin (various brand names) - and with cimetidine (various brand names), used for stomach ulcers and heartburn.
• If you have flu vaccinations, or develop certain illnesses, especially viral infections, heart disease or liver disease, watch for the typical side effects of theophylline-type drugs (see above) and consult your doctor immediately if any occur. These conditions all change the effects of theophylline-type drugs.
• Don’t eat meals that are very high in fats or oils. A lot of fatty food causes too much of the drug to be released at once from the slow-release preparations and increases the risk of side effects. Avoid sudden, major, changes to your diet.
• See your doctor regularly for check-ups. Simply getting older changes your reaction to these drugs: your dose may need to change over the years.
• If you are at all forgetful about tablets, keep a careful record of when you have taken your theophylline-type drugs. Be very careful never to take a second dose by mistake.
• Talk to your doctor if you are not taking a slow-release form of theophylline (see box below for brand names). There are usually fewer side effects from these than from the ordinary forms of the drug.
• Wear a Medic Alert bracelet (see box on p. 95) saying that you are taking theophylline-type drugs. If you have a severe asthma attack and are taken to hospital, it is important that medical staff know this, so that they do not give you more drugs of this type.
While pregnant or breast-feeding, it may be advisable to stop taking theophylline-type drugs: discuss this with your doctor. Although the drugs do not affect most unborn or newborn babies, there are occasional reports of toxicity. Less seriously, theophylline-type drugs go through into breast milk, and may make babies irritable and restless. This problem can be solved by always taking the drug just after a feed - this reduces the amount in the milk.
Theophylline-type drugs might produce behavioural problems and learning difficulties in young children although this is unproven. Research shows that there are no problems for children over six.
Anti-IgE drugs
For asthmatics with strong allergic reactions, who are not doing well on ordinary treatment, the new anti-IgE drugs, such as omalizumab may be very valuable (see p. 149). They are given as a depot injection under the skin.
Some common brand names
Common brand names of theophylline-type drugs include: slow-release preparations — Lasma, Nuelin SA, Phyllocontin Continus, Slo-Phyllin, Theo-Dur, Uniphyllin Continus
ordinary preparations - Aminophylline, Nuelin Ketotifen
Ketotifen (brand name Zaditen) is an antihistamine (see p. 138), although it has other effects in addition to those of ordinary antihistamines. Most significantly, it stabilises mast cells in a similar way to cromoglycate.
One advantage of ketotifen to many people is that it is taken by mouth, in capsule, tablet or syrup form. When it was first introduced, doctors hoped that it would be of particular help in asthma, but it has not lived up to expectations. However, some asthmatics do find it effective. It is worth trying because, it it works, it could permit you to reduce your dose of steroids.
Ketotifen requires up to six weeks to take effect, so continue taking your previous drugs (e.g. steroids) for at least six weeks, or you will risk losing control of your asthma.
Side effects
Minor side effects from ketotifen include nausea, headache, increased appetite and weight gain, drowsiness, dry mouth and slight dizziness. Do not drive until you are sure that ketotifen does not make you drowsy. Alcohol may pack a more powerful punch than usual, so drink very moderately at first. If drowsiness is a problem, take the drug in the late evening. The sleepy feeling may wear off after a few weeks of taking the drug.
There are no serious side effects from ketotifen, except if taken with drugs for diabetes.
Anti-leukotriene drugs
Leukotrienes are among the messenger chemicals that are produced by mast cells during an allergic reaction (see box on p. 12). They help to perpetuate the inflammatory process begun by histamine, and they amplify the reaction by attracting more immune cells into the area.
The anti - leukotriene drugs fall into two distinct groups:
• those that bind to the receptors for leukotrienes, called leu kotriene- receptor antagonists. Currently, there are two drugs in this group, montelukast (brand name Singulair) and zafirlukast (brand name Accolate). A third drug, pranlukast, is in the pipeline and currently going through its safety trials.
• those that block the production of the leukotrienes altogether, called 5-lipoxygenase inhibitors. There is only one drug in this group at present, zileuton (brand names Leutrol, Zyflo); it is not yet available in Britain.
As regards tackling inflammation, the anti - leukotriene drugs work in a completely different way from either steroids or cromoglycate. This makes them useful as an add-on treatment, supplementing the effects of existing anti-allergy drugs.
For asthmatics, anti-leukotriene drugs may be particularly good in combination with antihistamines – whereas antihistamines alone are singularly unsuccessful in asthma (see p. 138). Recent research suggests that taking antihistamines together with antileukotriene drugs is an effective way to control airway inflammation. However, there have been no large-scale trials of this treatment option yet, and it may be a while before it comes into general use.
In the airways of people with asthma, leukotrienes can directly trigger bronchospasm (contraction of the airway muscles) as well as fostering inflammation and increasing mucus production. This multiple action of leukotrienes makes anti-leukotriene drugs very valuable for asthmatics because they act as both relievers (reversing bronchospasm) and preventers (tackling inflammation). They are especially useful for exercise-induced asthma.
All the anti-leukotriene drugs are taken in tablet form. If you are trying an anti - leu kotriene drug for the first time, don’t expect any noticeable effects to occur for about three days. Once you are taking the drug regularly, each dose requires 2-4 hours to have its full effect, but goes on working for 12-24 hours in total.
Although anti - leu kotriene drugs have a reliever effect, they cannot give you immediate relief from bronchospasm. Asthmatics must therefore carry a short-acting beta-2 reliever (see pp. 152-3) as well, in case of an asthma attack.
For those who dislike inhalers, or tend to forget to use them, the fact that these drugs are taken once a day in tablet form makes them an attractive option. However, they are expensive, and at present doctors prescribe them mainly for young children who have difficulty inhaling their usual drugs.
Side effects
The side effects noted in safety trials of these drugs were all minor ones:
• zafirlukast – headache, nausea, diarrhoea, pain
• montelukast – headache, diarrhoea, abdominal pain, cough, and flu-like symptoms
• zileuton – upset stomach
As with all new drugs, you should report any unusual symptoms to your doctor, just in case these represent a rare or longterm side effect of the drug (see p. 137).
Very occasionally montelukast provokes allergic reactions, with symptoms such as itchiness, widespread nettle rash (urticaria) or swelling (angioedema).
Zafirlukast and zileuton can both cause liver damage, but this is rare. Your liver function should be closely monitored by the doctor, by means of regular blood tests, and the drug withdrawn at the first sign of trouble. Montelukast can also affect the liver, but this is extremely rare.
The most worrying development noticed to date is the appearance, in a very few people taking zafirlukast or montelukast, of a disorder called Churg-Strauss Syndrome. The symptoms may include a blotchy purplish rash (due to vasculitis – see lower box on p. 73), a flu-like illness, worsening asthma, and numbness or tingling in the limbs. The heart, lungs and nerves are all affected, because eosinophils (see p. 19) are present in large numbers and cause damaging inflammation.
A study of the cases reported so far suggests that this syndrome may not be due to the anti-leukotriene drugs themselves but to other causes – usually (though not always) a reduction in the dose of steroids. Other patients who are not taking antileukotriene drugs, but are reducing or stopping steroids, may also (again, very rarely) develop Churg-Strauss Syndrome. Doctors now suspect that all these patients were already suffering from an underlying eosinophilic disease, which first showed itself simply as asthma, and was quelled by the steroid treatment prescribed for the asthma. The disease was thoroughly masked as long as the patient was using steroids, but when steroids were withdrawn, the underlying disease flared up, producing a wide range of symptoms. In most cases, reintroducing steroids brings these symptoms under control again.
Putting it all together
What is the ideal combination of all these asthma drugs? That is something your doctor can only work out slowly, because it varies from one individual to another.
The conventional approach to asthma treatment is to start patients on a short-acting beta-2 reliever and then, if the symptoms are not controlled, to add other drugs. This approach is called ’stepping up’. The standard steps, or stages, are as follows:
1. Use a short-acting beta-2 reliever only.
2. Add cromoglycate or low-dose inhaled steroids.
3. Try a higher dose of inhaled steroid or a long-acting beta-2 reliever.
4. Try out each of the following in turn: theophylline, anticholinergic drugs, cromoglycate and higher doses of beta-2 relievers (either inhaled or as tablets/syrup).
5. If there is still no success in controlling symptoms, add regular steroid tablets.
Short courses of steroid tablets may be used at any stage, for the control of sudden, severe, attacks.
Over the last ten years, there has been a change of strategy, and very few people are now kept on Stage 1. Inhaled steroids are now given to most asthmatics, even those with relatively mild asthma. Research from Sweden, where widespread use of
inhaled steroids first became general policy, shows considerable benefits to this approach.
If you have gone beyond Stage 2, ’stepping up’ is usually followed by ’stepping down’. In other words, when the symptoms have been well controlled for 3-6 months, doses of some drugs are reduced, or certain drugs stopped altogether. If the asthma flares up again, the dose is increased or the drug reinstated. If there are no problems, and symptoms remain stable for a month or two, another reduction is tried.
An entirely different approach to asthma management is now being tried with some patients – starting off with moderate to high doses of inhaled steroids (equivalent to Stage 3) and then ’stepping down’. The idea is to get the inflammation under control promptly and fully at the outset. This often seems to be the best strategy.
A few asthmatics don’t get much benefit from steroids. If your dose of steroid needs to be raised repeatedly, or you still need to use your reliever daily in spite of taking steroids, you may have steroid-resistant asthma. There are other drugs that can help, including anti-leukotriene drugs and the more powerful anti-allergy drugs (see p. 149).
Alcohol, caffeine and asthma
Some asthmatics experience bronchodilation (opening up of the airways) when they drink alcohol, while others experience
bronchospasm (tightening of the airways). For those whose airways open up, there is probably no harm in sometimes having a drink to relieve your asthma symptoms, assuming these are fairly mild. Clearly, it would not be a good idea to make a daily habit of this.
If your airways tighten up with alcohol, you will probably be pleased to hear that it may not be the alcohol itself. Alcoholic drinks contain a great variety of other ingredients, either derived from the original ingredients or generated during the fermentation process. Called ‘congeners’, these vary from one type of alcoholic drink to another, and they are often the culprits in asthma. So you may well find that, while one kind of alcoholic drink has a bad effect, another is fine.
Caffeine has a far more uniform effect — for most asthmatics it opens up the airways. However, the amount needed to relieve an asthma attack will also produce unpleasant side effects, such as a pounding heart or shaky hands. There are also long-term problems with such high doses of caffeine, including insomnia, headaches, nervousness and ‘restless legs’. It is much better to use your reliever inhaler to control an attack: the drug in the inhaler has been chemically tailored to give the maximum therapeutic benefit with the minimum of side effects. Anyone who consumes tea or coffee excessively can make themselves seriously ill, either physically or mentally, and it is not always obvious that caffeine is the cause (see p. 235).

Various anti-allergy drugs
An allergic reaction is a lengthy, complex process, and the various anti-allergy drugs all work on different stages of that process. That is why it often makes sense to use several different drugs for the same allergic condition: they each tackle the problem in their own way.
Steroids (see p. 140) intervene at a very late stage, quelling the inflammation that follows on from an allergic reaction. Using a steroid is rather like calling the fire brigade to put out a fire, whereas using an antihistamine (see p. 138) is like having fire-proof doors, to prevent the fire spreading at an early stage. Cromoglycate-type drugs (see below) intervene at an even earlier stage. They are like basic fire prevention - teaching children not to play with matches, or fitting smoke detectors.
Anti - leukotnene drugs (see p. 149) work at roughly the same stage of the process as anti-histamines but tackle an entirely different aspect of the allergic reaction.
Cromoglycate-type drugs
These drugs are also referred to as mast-cell stabilisers or mast-cell Mockers.
There are three drugs in this group, sodium cromoglycate (also spelled cromoglicate), nedocromil sodium, and lodoxamide. All operate at an early stage of the allergic reaction, stopping it before it actually starts. They stabilise the outer membrane of the mast cells (see box on p. 12), which prevents the allergic response from occurring.
Some common brand names
Common brand names of cromoglycate-type drugs include:
inhalers - Cromogen Easi-Breathe, Intal, Tilade
eye drops - Hay-Crom, Opticrom, Rapitil, Vividrin, Viz-on nose sprays - Rynacrom, Vividrin
capsules - Nalcrom
This is a far more satisfactory way of dealing with an allergic reaction than trying to tackle it after the reaction has occurred. But from a purely practical point of view, it has a drawback. I order to work at all, these drugs must reach the mast cells in advance of the allergen. They are of very little use if taken after the allergic reaction has begun.
For those who are taking cromoglycate-type drugs on a regular schedule, several times a day, it is very important to be conscientious about taking them on time. This maintains the protective effect of the drug, without any gaps.
If you are using these drugs on an ‘as-needed’ basis, you should take them 30 minutes before an allergen is encountered. or 30 minutes before a bout of exercise, if they are being prescribed for exercise-induced asthma. (Note that children sometimes respond differently, getting protection from these drugs immediately.)
The effect of these drugs takes time to build up. You should take them regularly for at least four weeks before deciding whether they are helping you or not.
One point in favour of cromoglycate-type drugs is that they are extremely safe, with few or no side effects in most people. Sadly, they do not work for everyone. A fairly high percentage of children respond well to them, but the response rate is much lower for adults. Nevertheless, adult allergy sufferers, especially those who need steroids to control their symptoms, should always be given the opportunity to try out these drugs. When cromoglycate-type drugs do work, they are very effective and almost always trouble-free, so they are a good alternative to steroids.
Both sodium cromoglycate and nedocromil sodium are available in inhaler form for asthma (see p. 157). Sodium cromoglycate is also available as nose drops for hayfever and other nasal allergies.
All three drugs are available as eye drops. Recent evidence suggests that sodium cromoglycate drops are less effective than the other two, particularly for the treatment of severe allergic conjunctivitis (inflammation of the eye).
Sodium cromoglycate is available in capsule form for food allergy. Note that these capsules are of very limited value in food allergy, and are certainly not a substitute for food avoidance. They do reduce sensitivity a little and can sometimes be helpful for those with multiple food allergies (see p. 67).
Side effects
There are no serious side effects at all for nedocromil sodium. cromoglycate can, very rarely, cause joint pain and swelling. An allergic reaction to the drug itself is even more uncommon. Stop taking the drug and see your doctor promptly if either of these occurs.
The only other side effects that have occasionally been reported are headache, nausea and vomiting. None of these indicates any damaging effect by the drugs – they are all minor side effects.
Eye drops containing these drugs may cause stinging and burning when inserted, but this is a minor side effect and usually wears off. Flushing and dizziness have sometimes been reported with lodoxamide eye drops.
Nose drops may also cause local irritation. This could be due to the drug itself, in which case it is a minor side effect. Alternatively, the irritation may be due to the preservative used or some other non-drug ingredient (see box on p. 33).
Occasionally cromoglycate nose drops cause bronchospasm – contraction of the airway muscles – but this tends to wear off quite quickly. Bronchospasm can also occur when cromoglycate-type drugs are inhaled (see p. 157).
Anti - leu kotriene drugs
These drugs, which have a set of very specific effects (see p. 159), were originally designed to treat asthma. Their potential for treating other allergic diseases is currently being explored:
•    Several studies show that they work well for perennial allergic rhinitis brought on by allergens such as house-dust mite. They also have some effect on hayfever, but standard treatment (such as antihistamines plus a steroid spray for the nose) is more effective.
•    They are especially useful for both rhinitis and asthma in patients suffering from triad (see box on p. 28). Research shows that they also reduce asthmatic reactions to very small test doses of aspirin, but they don’t give protection against anaphylaxis brought on by normal doses.
•    They have also been used successfully in cases of chronic urticaria and for some patients with delayed pressure urticaria. It seems plausible that they would also be helpful for chronic urticarla linked to aspirin sensitivity.
•    Preliminary trials suggest that these drugs might be useful in atopic eczema. Some studies show a very good response that allows a reduction in steroid creams.
•    Montelukast works very well for eosinophilic gastroenteritis and eosinophilic oesophagitis (see p. 72), according to some new studies.
For side effects of these drugs see pp. 159-60.
Anti-IgE drugs
Since the antibody IgE (see box on p. 12) is such a crucial player in allergic reactions, developing drugs that disable this antibody should help allergy sufferers. The first such drug is omalizumab (brand name Xolair) which was licensed for use in the United States in 2003. It is expected to become available in Britain some time in the next few years.
Omalizumab binds to IgE antibodies and stops them from interacting with mast cells, so blocking any allergic reaction. The drug is given as a ‘depot injection’, just under the skin, every 2-4 weeks. It is gradually released from the injection site and moves around the body in the blood, mopping up IgE molecules.
At present, omalizumab is used for severe hayfever and for people with asthma who are not responding well to the usual treatments. It is only worth using if there is clear evidence that allergies play a part in the asthma. Patients who use omalizumab are often able to reduce their dose of inhaled steroids – and they suffer fewer serious asthma attacks and have better lung function. Some patients can even stop using steroids completely.
Other anti-IgE drugs are in the pipeline. Pilot studies show that one works very well for peanut allergy: after just four injections, sensitivity to the allergen falls sharply, reducing the risk of anaphylaxis from traces of peanut eaten accidentally.
More powerful anti-allergy drugs
Occasionally people with severe allergies, who are on constant high doses of steroid tablets, or who fail to respond to steroids, need treatment with powerful anti-inflammatory drugs, such as methotrexate or cyclosporin. These suppress the immune system, and extremely careful monitoring for side effects is needed.
Adrenaline (epinephrine)
Anyone who has suffered anaphylactic shock (see p. 58) should be carrying a special syringe, called an auto-injector, loaded with adrenaline. The injector is very simple to operate and is designed for emergencies. Most allergy sufferers, even children, can give themselves the injection – or a parent or other adult can give it.
Some asthmatics, and those with food allergy who suffer swelling of the throat, may be given adrenaline in inhaler form as well (see pp. 155-6). This can be useful as an additional treatment but it’s definitely not a substitute for an injector.
See pp. 98-9 for instructions on using adrenaline in a crisis.
Wherever you go, take your injector with you. Always keep it close at hand: you need to be able to use it within minutes of the allergic reaction starting. You may be unable to speak (and therefore unable to ask someone else to fetch it) quite soon after the attack begins. The injector must never be refrigerated. It can also be damaged by sunlight and excess heat.
If you live in the countryside or in an area with a poor ambulance sevice, or if you are going camping or hiking somewhere remote, ask your doctor for a second injector, or one that can deliver multiple injections. Also ask about the maximum number of injections that can be given, and never exceed this total. Some doctors believe everyone should have two injectors, just in case the first dose doesn’t do the trick and help is slow in coming.
It is vital that you are shown exactly how to use the auto-injector. Canadian researchers discovered that only one in four
Some common brand names
Common brand names of adrenaline preparations include: auto-injectors – Anapen, EpiPen
inhalers – AsthmaHaler Mist, Bronkaid, Epiphrine
health professionals got the technique correct when demonstrating how to use an auto-injector In this study, pharmacists were much the best as regards accurate instructions. Dummy injectors are useful for training purposes and most pharmacies have them.
When the adrenaline auto-injectors expire, they can be very useful for practising with, or for showing a new baby-sitter or teacher – practise on an orange or grapefruit.
If you are taking beta-blockers (e.g. for a heart condition or anxiety), adrenaline may not have much effect.
Heavy daily use of beta-2 relievers for asthma (see p. 152) will also make adrenaline less effective when you need it.
Side effects
The important side effects of adrenaline involve the heart. Anyone with a heart condition should be given special advice in advance by their doctor about using adrenaline. The same goes for people with diabetes, hyperthyroidism or high blood pressure, and anyone taking tricyclic anti-depressants. There are quite a few minor side effects from adrenaline, such as anxiety, trembling, nausea. sweating, dizziness and cold extremities. These soon wear off.
Drugs that can make you worse
Aspirin and its relatives have a very bad effect on some people with rhinitis and/or asthma (see box on p. 151). Unfortunately, recent research shows that paracetamol is not safe either. It makes asthma more likely to develop in those who do not yet have the disease, and increases the severity of asthma symptoms for those who do. Unlike aspirin, paracetamol affects everyone, because it lowers the levels of a natural antioxidant, called glutathione, which the body makes to protect the lungs from oxidants. The greatest effects are seen in people who take paracetamol regularly (once a week or more), but even an occasional dose makes some difference.
All the other drugs that can make you worse are prescription drugs, and your doctor should be alert to the dangers. But doctors are overworked and sometimes forget, so it is sensible to know about the risks for yourself. If you have any doubt about the drugs you are taking, ask a pharmacist.
Beta-blockers are a major hazard for people with allergies. They can make the airways contract, and can bring on a serious asthma attack. They also make anaphylaxis more likely in someone who already has allergic reactions (see p. 59) and they increase the risk of a severe reaction to
immunotherapy (see p. 166) or skin-prick tests (see p. 91). Beta-blockers are prescribed for high blood pressure, angina and other heart problems, migraine and thyroid disease. There are alternative drugs in all cases. Sometimes asthma develops in people who have been taking beta-blockers for years. The beta-blockers are not responsible for this, but once asthma has begun, they will make symptoms worse. Eye drops for the treatment of glaucoma may also contain beta-blockers and can have a bad effect on asthmatics.
ACE inhibitors, used for heart conditions, may cause a cough and airway narrowing. They may also increase the risk of a severe reaction to immunotherapy.
Female hormones affect asthmatics, so taking the contraceptive pill or hormone replacement therapy (HRT) may make asthma worse. Progesterone-only contraceptive pills tend to cause fewer problems.
The drug isoniazid (INH), prescribed for tuberculosis, makes the body far more susceptible to histamine in foods (see p. 200).
An allergic reaction to a specific drug (e.g. penicillin) can also occur in some people, resulting in urticaria, or even anaphylactic shock.
Aspirin sensitivity
Aspirin sensitivity is not an allergic reaction, because neither IgE nor mast cells are involved. What causes this problem is a metabolic abnormality — a malfunction in one aspect of the body’s chemistry. The details of this are very complicated: you may want to skip the next three paragraphs and
simply read about how to cope with the problem.
The exact nature of aspirin sensitivity is still far from clear, but it seems to involve a relatively poor production of prostaglandins, combined with a plentiful production of leukotrienes. Both these substances are messenger chemicals which, broadly speaking, promote inflammation. But the details of their pro-inflammatory activities differ. It seems that, ideally, the body should have a harmonious balance between the two, and an imbalance produces problems.
Both prostaglandins and leukotrienes are manufactured from certain fats that are found in the diet. These fats, the raw materials, are worked on initially by two different enzymes — one that leads to the production of prostaglandins and another that leads to the production of leukotrienes.
If one of these enzymes is defective, it may mean that the other is oversupplied with raw materials, resulting in a serious imbalance between prostaglandins and leukotrienes. In those with aspirin sensitivity, or at risk of developing aspirin sensitivity, the enzyme that produces prostaglandins seems to be defective.
Even in the absence of aspirin, this imbalance in the production of prostaglandins and leukotrienes causes problems. It leads to symptoms such as chronic urticaria (see p. 51) or rhinitis, nasal polyps and asthma (a cluster of symptoms that is commonly called triad — see box on p. 28).
Taking aspirin can make the imbalance between prostaglandins and leukotrienes even worse in a person with this underlying abnormality. Aspirin exerts its painkilling effects by disabling the main prostaglandin-making enzyme — the enzyme that is already defective.
When someone with aspirin sensitivity takes aspirin, they may suffer worsening asthma, a severe asthma attack or — the worst-case scenario —collapse. This is a potentially fatal reaction, similar to anaphylaxis, requiring emergency medical treatment (see p. 101).
The greatest puzzle about aspirin sensitivity is why it often takes so long to develop in someone who already has the symptoms of triad —indicating the basic metabolic abnormality. It may be as much as 20 years from when someone has their first triad symptoms to when they begin reacting badly to aspirin.
If you have triad symptoms already, but no aspirin sensitivity yet, what should you do? Unfortunately, there are no safe tests for aspirin sensitivity at present — taking a small dose of aspirin and seeing what happens is very hazardous. It is probably best to assume that you are going to become sensitive to aspirin at some stage, and avoid all aspirin and aspirin-like drugs. Caution is the best plan here because aspirin sensitivity can come on very suddenly, and be life-threatening the very first time it occurs. Note
that some triad sufferers have polyps and rhinitis but no asthma until they actually develop aspirin sensitivity — a dose of aspirin suddenly brings on their first asthma attack plus other symptoms of aspirin sensitivity.
Avoiding aspirin itself is not difficult, but aspirin-like drugs pose more of a problem. Every year there are a number of deaths from these drugs. Some cases occur because a busy doctor momentarily forgets that a patient should not take these drugs. The drugs that need to be avoided are all known as non-steroidal anti-inflammatory drugs (NSAIDs), COX-1 inhibitors or COX-2 inhibitors. However you will not see any of these names on the packet. These drugs are very widely used for pain relief (e.g. in headache and backache remedies such as Nurofen), for the treatment of arthritis, and for several other inflammatory diseases.
There are dozens of non-steroidal anti-inflammatory drugs available, and many are sold under several different brand names. The list grows every year, as new drugs or new brands are launched. The only way to avoid these drugs is to be very cautious:
•    When buying any cold- or flu-remedies, painkillers, medicines for sprains or sports injuries (including those you apply directly to the skin), headache tablets or migraine tablets, always buy them at a chemist’s shop rather than a supermarket, and check with the pharmacist that they do not contain aspirin or aspirin-like drugs.
•    Be cautious also about remedies for an upset stomach. A few (e.g. Alka-Seltzer) contain aspirin.
•    Don’t take any drugs unless you are 100% sure of what they contain. Remember that the ingredients of a familiar brand name can sometimes change — read the label every time.
•    When a doctor prescribes any new drug, always mention that you are sensitive to aspirin, or that you have triad symptoms. Alternatively, check with the pharmacist when the prescription is filled.
•    Aspirin-free painkillers almost always contain paracetamol, a drug which can cause a severe reaction (similar to the collapse induced by aspirin itself) in about 5% of those with aspirin sensitivity. If you are taking paracetamol for the first time, start with half a tablet. Be sure that, for the next 2-3 hours, you have a way of getting to hospital quickly should you start to feel ill. (Note that paracetamol has another entirely separate effect, increasing the severity of asthma, and it is best not to take it too often — see box on p. 150.)
Avoiding all aspirin-like drugs will prevent you having anaphylaxis or severe attacks of asthma. Unfortunately, triad symptoms will not go away however careful you are about avoiding aspirin.
It is well worth trying the new anti-leukotriene drugs (see p. 149), especially if you have aspirin-induced asthma. They seem to help with triad symptoms by curtailing the activities of leukotrienes and so redressing the balance between leukotrienes and prostaglandins.

Few drugs create quite so much alarm as corticosteroids. To some extent, this alarm is justified — if

over-used, they have dangerous side effects. But rejecting them entirely is a great mistake, because

they are safe at the right dose, and immensely useful for a variety of allergic symptoms. With the

information given here, you can use steroids as safely and effectively as possible.
Although their proper name is corticosteroids, these drugs are commonly — and rather inaccurately —

called steroids. This name adds to their doubtful reputation by confusing them with the notorious

anabolic steroids (see box on p. 142). However, the term ’steroids’ is used for corticosteroids in this

book, simply because that is the name most people recognise.
Steroids do not deal with the allergic reaction itself, unlike antihistamines (see p. 138) or

cromoglycate (see p. 148). Instead, they tackle the consequences of the allergic reaction,

inflammation.
What exactly is inflammation? The visible features of this phenomenon – for example, if it occurs in

the skin, around a scratch or cut – are redness and slight swelling. There is also soreness, and some

warmth. All these effects are produced by an influx of immune cells, intent on protecting the broken

skin from infection. These immune cells generate messenger chemicals (see box on p. 10) which boost the

inflammation, as well as attracting yet more immune cells to the area. When inflammation affects

delicate membranes, as when you suffer a sore throat for example, there can be a great deal more

swelling and discomfort.
The inflammation that follows allergic reactions is very similar to that provoked by infection,

although the balance of immune cells and messenger chemicals is slightly different. Eosinophils (see p.

19) play a particularly important role in sustaining the inflammation produced by allergies.
This influx of eosinophils and other immune cells, which lights the fires of inflammation, occurs some

hours after the allergic response itself. It is known as the Late Phase Reaction (see p. 13). Steroids

work well for allergies because they curtail the Late Phase Reaction and have a calming effect on

various immune cells, especially the eosinophils.
Steroid phobia
So many patients have a profound objection to taking steroids that doctors call it, half-jokingly,

’steroid phobia’. One of the hazards of giving information about potential side effects – as in this

book – is that it may encourage ’steroid phobia’. That would be a tragedy, because steroids really are

useful drugs that can do you a lot of good and very little harm, if used correctly. The risks are very

small when the steroids are used at low to medium doses, and targeted directly onto the inflammation.

Even with high doses, the serious side effects can generally be avoided. Please don’t use the

information here to scare yourself – instead, use it to protect yourself while getting the most from

steroid treatment.
A few effects on other body processes remain, even with the new steroids:
•    Raised blood pressure – this can occur even with short-term use of steroids.
•    Children may stop growing, or grow more slowly. Usually they make up for this later.
•    Quite commonly, there is increased hunger (though you don’t actually need more food, and will

put on weight if you eat more than usual). Insomnia and an agitated, edgy feeling during the day may

occur. These are minor side effects, and no cause for concern.
•    Side effects in the eye can occur: there is an increased risk of glaucoma and, with prolonged

use, cataracts.
•    Long-term use can also result in loss of minerals from the bones, leading to thinning and

fragility (osteoporosis).
•    Psychological changes may occur. Some people experi- ece euphoria or greatly increased energy

levels – with the opposite effects occurring when the course of steroids ends. At worst, steroids can

trigger paranoia or severe depression and suicidal feelings. (These effects are more likely to occur in

those with a history of mental illness. If you are concerned about this aspect, discuss the possible

risks with your doctor before taking steroid tablets.)
•    Epileptics may suffer more frequent or more severe seizures.
•    Very rarely, stomach ulcers develop, or other side effects in the digestive system.
•    The skin may become thin, and the small blood vessels beneath it more fragile, leading to easy

bruising and stretch marks (striae). This is also a potential problem with steroid creams (see p. 146).

Elderly patients are much more susceptible to this side effect.
•    Some diabetics need more insulin. in addition, anyone with the potential to develop diabetes is

more likely to do so, but only if taking steroid tablets long term. The diabetes usually goes when the

steroids are stopped.
•    A few men suffer impotence, but only with long-term use of tablets. This can be treated, so see

your doctor. Women may have irregular periods.
•    Damage to the hip bones may rarely occur, usually with excessive doses of steroid tablets. This

is called avascular necrosis and may require hip replacement.
In addition to these effects on other body processes, there are also some side effects that arise from

the steroids’ suppression of the inflammation. These can occur even with short courses. Again, however,

these problems can almost always be prevented, or treated, or reversed if detected at an early stage.
•    Skin wounds may be slow to heal, and are more likely to become infected because of reduced

immunity. This is not a serious problem – just keep all cuts as clean as possible.
•    Infections by viruses and fungi (e.g. Candida – see box on p. 83), may occur more readily.
•    Some infections may be masked initially because fever is suppressed by the steroids.
•    Chickenpox and measles can be far more serious – even fatal – if steroid tablets are being

taken, or have been taken for more than three weeks within the last three months. This is something to

be very careful about (see item 15 on p. 143).
•    Prolonged use can increase the risk of chest infections.
•    Vaccination with live vaccines can cause problems.
•    Older people who once suffered from tuberculosis (TB) may find it comes back.
•    Steroids can lead to pregnancy if using an IUD, because IUDs work by inducing mild inflammation

in the womb.
The most insidious effect of steroids – and remember again that this is only a hazard of prolonged

high-dose treatment – is adrenal suppression. When steroid tablets are taken for more than three weeks,

the adrenal glands’ own ability to produce cortisol (see p. 141) starts to be slightly suppressed. The

longer the course of steroids, the greater the effect. Stopping the steroids abruptly leaves the body

without enough cortisol to protect itself, which, in the very worst cases, can lead to collapse. Less

obviously, there may be greater vulnerability to the effects of accidents, serious illnesses, surgery

or childbirth – demanding events that would normally stimulate a rise in cortisol production to help

the body cope with the stress.
If you take a short course of steroid tablets during this period, there is more risk of side effects

than normal. Adrenal suppression can last for 6-12 months after steroid treatment ends. It may be two

years before the body can cope with surgery unaided and you will need low doses of steroids to get you

through stress of this kind.
Will I look like a weight-lifter?
Absolutely not. The steroids taken by unscrupulous athletes to pump up their muscles artificially are

anabolic steroids. They are entirely different from the corticosteroids used to treat allergies.
Mimicking nature
All corticosteroids are chemically very similar to a substance known as cortisol that is produced

naturally by the body. Cortisol – which is a hormone made in the adrenal glands, located near the

kidneys – has a great number of different effects, apart from damping down inflammation. It regulates

the action of the kidneys, moves proteins out of the muscles and bones, and alters the pattern of fat

distribution.
Like other hormones and chemical messengers that the body produces, cortisol achieves its effects by

binding to receptors on target cells (e.g. immune cells, muscle cells and the cells that make up the

kidneys). These receptors vary a little, which gives researchers scope for making a synthetic version

of the hormone, cunningly modified so that it binds well to one kind of receptor (the one on the immune

cells, for example) but not so well to another (the one on the kidneys).
Hydrocortisone, the original steroid drug, is identical to cortisol, but the newer steroids have been

modified chemically to have the maximum effect on inflammation and minimal effects on other body

processes. While hydrocortisone can only be used for allergies at very low doses (as in

non-prescription hydrocortisone cream), the modified steroids can be used at higher doses.
The side effects of steroid drugs are of two basic kinds:
•    those due to suppression of inflammation (the desired effect of the drugs) because this

partially reduces immunity to disease
•    those due to the effects of steroids on other body processes – undesirable effects which have,

as far as possible, been designed out of the modern drugs.
These different side effects are discussed in more detail on p. 142. First, it is important to look at

the crucial difference between taking steroids in tablet form and applying them directly to the

affected area. Much unnecessary anxiety can be avoided by understanding this difference.
Targeting steroids
The risks of steroids fall dramatically if, instead of taking them in tablet form, you put them exactly

where they are needed: that means drops for the nose or eyes, inhalers to get the drug into the

airways, or creams and ointments to target the skin.
The medical term for this is topical application, and it is infinitely preferable to taking steroid

tablets. When a drug is swallowed, it does its job by being absorbed through the stomach lining into

the bloodstream, and then being carried around the body in the blood. This is called systemic treatment

because it reaches the whole body-system via the blood.
The areas that need the drug – the itchy skin or inflamed airways – get their dose, but so does every

other part of the body. In order to get a useful amount to the afflicted parts, a fairly large total

dose has to be taken which inevitably affects the rest of the body, making the drug far more hazardous.
When a drug is targeted precisely, in sprays, drops, creams or inhalers, the dose used can be very much

smaller. Some of the drug does get into the bloodstream, by penetrating the skin or the membranes of

the nose or airways, and entering the tiny blood vessels that lie just below. But the amount reaching

the bloodstream is usually minuscule compared with the amount in the blood when you take steroid

tablets. Systemic side effects –those due to the drug going round in the blood (see below) – are

usually avoided, although there may be some local side effects, where the drug is applied.
Only with very powerful doses – as in the steroid inhalers used for severe asthma, or high-potency

creams for eczema – do topical steroids reach the bloodstream in sufficient amounts to cause systemic

side effects. You have to be on these treatments for a long time, or be overdoing the dose (a possible

hazard with creams for eczema), to run the risk of systemic side effects.
Steroid tablets
Short courses of steroid tablets – which means three weeks or less – are pretty safe. They are usually

sufficient to get the inflammation under control, and can be taken three or four times a year without

creating any problems.
Even if you have no choice but to take steroid tablets on a long-term basis, remember that the serious

side effects can usually be avoided, or reversed if caught early (see p. 143).
Side effects
Apart from changes that may (rarely) occur in the stomach lining, the side effects of steroid tablets

are all systemic side effects.
In the early days of steroid use, a set of side effects that resemble a disease known as Cushing’s

Syndrome were frequently seen. The side effects included deposits of fat on the shoulders and abdomen,

and around the face, producing a ,moon face’, water retention resulting in puffiness, weakening of the

bones, easy bruising, acne and muscle wasting. All these changes are due to the unwanted effects of

steroids on other body processes, not to any effect on inflammation.
With the new and improved steroids (see left), plus a much more watchful approach by doctors, these

severe side effects have become very rare, but they can still occur in those on high-dose steroid

tablets. As long as they are noticed in good time (see p. 143) the problem can be reversed.
Using steroid tablets safely
Those taking steroid tablets for more than three weeks, or taking a lot of short courses, can protect

themselves from serious side effects in the following ways:
1. Weigh yourself every day. Should your weight suddenly start to rise, despite eating normally,

consult your doctor: this may be a sign of water retention.
2. If you develop hip pain, swollen ankles, muscle weakness or acne tell your doctor.
3. Get your blood pressure checked regularly by the doctor.
4. Get your eyes checked regularly by an optician, who can detect any problems before there is

irreversible damage.
5. In the case of children, make sure the child’s growth is being monitored carefully by the doctor.
6. Stay as active as possible, with plenty of vigorous exercise, to protect against osteoporosis. Avoid

getting too thin, as this is also a risk factor for osteoporosis. Reduce your salt intake and don’t

drink too much alcohol. Ask your doctor to order a bone-density measurement periodically. Following the

menopause, women on steroid tablets should consider taking hormone replacement therapy (HRT) as this

protects against osteoporosis.
7. Persistent unexplained back pain must be reported to your doctor: this can be a sign of

osteoporosis. If you fracture your wrist in a fall (a Colles’ fracture) make sure your doctor knows

about this, and prescribes urgent drug treatment for osteoporosis.
8. See your doctor if you are over-tired, thirsty, or need to pass urine much more frequently – these

can sometimes be signs of diabetes.
9. Take your tablets after food to protect the stomach. See your doctor if you have persistent

indigestion: coated forms of the tablets may help.
10. If you ever produce black, tarry stools, call your doctor immediately. This is generally a sign of

bleeding from the digestive tract.
11. With your doctor’s permission, take all your daily steroids as a single dose in the morning. The

long gap between one dose and the next stimulates the body to maintain its own steroid-making abilities

and so reduces the risk of adrenal suppression. It can also protect against growth problems in

children. Even greater protection comes from taking steroids on alternate days – one day on, one day

off – although not everyone can keep their symptoms under control with this regime. Obviously, you must

consult your doctor before you try. Your dose may need adjusting.
12. Adrenal suppression puts you at risk during any medical procedure. Tell your doctor, dentist, and

anyone treating you in an emergency – even if you stopped taking steroids up to two years earlier. You

should also carry a Steroid Card at all times, in case you are unconscious. These cards are available

from your doctor.
13. Ask the doctor what you should do if you develop any kind of infection or suffer an accident. It is

often necessary to increase the dose of steroid tablets.
14. Tell your doctor if you have ever had tuberculosis, as this can recur.
15. If you or your child have not had measles or chickenpox, avoid contact with anyone suffering from

these diseases – or from shingles (herpes zoster) which is caused by the chickenpox virus. See your

doctor promptly if there is any contact with someone infected. Emergency treatment to combat the virus

must be started promptly.
16. When being vaccinated, remind the doctor or nurse that you are taking steroid tablets.
17. Never stop taking steroid tablets abruptly if you have been taking them for more than three weeks,

as some degree of adrenal suppression may already have begun. Your body needs time to recover its

natural level of activity, so reduce the dosage gradually. Get precise instructions from your doctor

about how to do this.
18. If you are asthmatic, at the end of any course of steroid tablets lasting more than three weeks, be

extra careful about exposure to allergens and asthma triggers. You may be more vulnerable to severe

asthma attacks for as much as a year after long-term steroid tablets are stopped, or the dosage

reduced.
Watch out for adrenal suppression
If you develop any of the following symptoms after stopping steroids,
or while reducing the dose, call your doctor as soon as possible:
•    muscle weakness; muscle and joint pain
•    feeling ‘under the weather’
•    mental changes
•    scaly or flaking skin
•    breathlessness
•    lack of appetite; or nausea and vomiting
•    fever and weight loss
•    painful itchy lumps on the skin.
Note that, very rarely, withdrawal of steroid tablets, or lowering the dose, can unmask a disease

called Churg-Strauss Syndrome (see p. 160).
Steroid nose drops and sprays
Most steroid nose drops and nasal sprays contain very low doses of the drug, and produce no significant

side effects when used for short periods of time. The safety of these preparations is such that several

are available without prescription.
Steroid drops and sprays for the nose are a very effective way of treating hayfever and perennial

allergic rhinitis. They can be used after the symptoms have begun, or in advance of encountering the

allergen.
Steroid nose drops are also useful in reducing the size of nasal polyps (see p. 30) but only if the

drops are inserted correctly. Kneel down and, bending your neck forward as much as possible, put the

crown of your head on the floor. Now put the drops in and stay in this position for several minutes

while the drops reach their target. Once the polyps have shrunk, the drops can be replaced by a steroid

spray which will keep them under control.
Always stick to the stated dose, as with any drugs – don’t use the drops or spray more often than you

should. If you have a cold or other infection in the nose, stop using steroid drops and sprays until it

is better. Following surgical operations on the nose, ask your doctor’s advice before using steroid

drops or sprays.
Side effects
Minor short-term side effects may include dryness and irritation in the nose and throat, and

disturbances of smell and taste. Nosebleeds might occur and should be reported to your doctor. When

inserting the drops, try to keep them away from the central partition of the nose (the septum), as this

is
the part most vulnerable to bleeding. If you are a long-term user of steroid nose drops, your doctor

should check the membranes in your nose regularly, to be sure that they are not becoming thinned. Eye

checks may also be advisable with long-term use, as glaucoma can occur.
Allergic reactions to the steroid are possible, and they can cause bronchospasm (contraction of the

airway muscles) though this is unusual. You should obviously stop using the drops and see your doctor

if this occurs.
With very high doses of steroids in the nose, or prolonged treatment, some systemic side effects might

occur. The main cause for concern is children’s growth (see box on p. 145) – their height should be

checked regularly.
Steroid eye drops
Steroid eye drops are sometimes given for severe inflammation of the eye during the hayfever season.

However, the eye is vulnerable to infections if treated with steroid drops, and such treatment requires

close medical supervision.
Side effects
Be extremely careful about infections – don’t rub your eyes with your fingers, for example, or dry

around your eyes with a towel unless it is absolutely clean. Follow your doctor’s instructions very

carefully, and go back immediately if your eyes become more uncomfortable, if redness increases, or if

you have any other cause for concern.
Steroid eye drops are rarely used for more than a few weeks. With prolonged use, there is a risk of two

serious side effects, glaucoma and cataract.
Using two lots of steroid
Allergy sufferers who need steroid nose drops or a nasal spray, as well as a steroid inhaler, often

worry that they are getting too much steroid overall.
In fact there is no cause for concern, unless you are taking very high doses of inhaled steroid, in

which case talk the matter over with your doctor. The amount in most nose drops and sprays is quite

small and the same is true of steroid eye drops. In all cases, relatively little gets into the

bloodstream.
If you have allergies in the nose, this may well be making your asthma worse, and using steroid nose

drops can be very helpful for the asthma symptoms (see p. 39).
Inhaled steroids and children’s growth
If an asthmatic child inhales relatively high doses of steroids for many years, his or her growth can

be stunted. However, only a small number of children need these high doses, and with low to moderate

doses most children’s growth is unaffected. They may experience a short-term slow-down in growth, but

their eventual height should be normal.
Unfortunately, there are a few children whose growth is stunted even by relatively low doses of inhaled

steroids - and it is impossible to predict which children will respond in this way. However, if it is

noticed in good time, and if the steroids can be withdrawn safely, the child’s growth rate will almost

certainly recover.
Your GP or paediatrician should be monitoring your child’s growth. You can also measure this yourself,

and go back to the doctor if you are concerned. Keep the risks in perspective - uncontrolled severe

asthma also stunts children’s growth, as well as endangering the child in far more serious ways, so

don’t stop using the steroid inhaler.
Steroid inhalers
Inhaled steroids are a key part of the modern treatment of asthma (see p. 157). As with other topical

treatments, inhaled steroids are a great deal safer than steroid tablets. However, some of the drug

does get into the bloodstream, and with high-dose inhaled steroids taken for several years, the levels

can be high enough to cause systemic side effects such as osteoporosis (see p. 142).
The dose is the crucial factor here. The packaging or information leaflet that comes with your inhaler

will tell you how much of the drug is delivered with each inhalation. To interpret the information

about side effects correctly, you need to know your total daily consumption of inhaled steroid, and

whether this corresponds to a low, medium or high dose:
•    For budesonide or beclomethasone, two of the more common steroids, less than 400mcg

(micrograms) per day counts as a low dose for adults and children over the age of five. A moderate dose

is 500-800mcg per day, and more than 800mcg a day is a high dose.
•    For fluticasone (Flixotide), halve these figures (i.e. more than 400mcg a day is a high dose).
•    In the case of children under five, all these figures should be halved (e.g. a high dose of

beclomethasone is more than 400mcg a day).
•    For other steroids, check with your pharmacist.
Anyone taking a low or moderate dose has very little to worry about as regards systemic side effects.

Only those inhaling high-dose steroids for many years need feel concerned.
If you may be at risk of systemic side effects, follow the protective measures described for steroid

tablets on p. 143. Apart from growth suppression in children (see box above) the most likely effects

are osteoporosis, adrenal suppression, and a recurrence of tuberculosis.
You can minimise the risk of systemic side effects from
steroid inhalers by swallowing as little as possible of the steroid. Always rinse out your mouth,

gargle, and spit out the water after using your inhaler. Using your steroid inhaler morning and

evening, just before brushing your teeth, will make it much easier to remember to do this.
Bear in mind that inhaling steroids regularly will help you avoid the need for steroid tablets.

Asthmatics who are worried about side effects sometimes skip doses of their inhaled steroids, then find

their asthma is much worse and that they need a course of steroid tablets. Frequent courses of tablets

increase the risk of serious side effects.
Minor local side effects of inhaled steroids include hoarseness and short-lived coughing due to direct

irritation of the throat. These are no cause for concern.
If you are regularly inhaling steroids from a nebuliser, make sure the mask fits really well (see p.

163).
Because steroids reduce the immune defences a little, one common side effect of inhaling them is a

throat infection by Candida (see upper box on p. 83). Oesophageal infections with Candida can also

happen but these are rare; the symptoms are heartburn and indigestion. Gargling with warm water after

each inhalation will help prevent Candida infections. There are also anti-fungal lozenges, if you are

still having trouble.
Keep inhaled steroids away from your lips if you suffer from cold sores (herpes infections around the

mouth). These can be made worse with steroids.
Fortunately, other infections are no more common when using inhaled steroids. This includes chest

infections.
Recent research has found other side effects in children using high doses of inhaled steroids. Cough

and thirst are common, while hoarseness and loss of voice affect quite a few. Behavioural problems also

occur, including hyperactivity, mood swings, excitability, sleep disturbances, depression, and even

hallucinations.
Steroid creams and ointments
Steroid creams and ointments are used for both atopic eczema and contact dermatitis. By delivering the

drug to the place where it is needed, they reduce the dose required to an absolute minimum and, if used

correctly, are very safe. Dr Ernst Epstein, a dermatologist at the University of California, observes

‘All too often I encounter children who are miserable with uncontrolled atopic dermatitis because of

their parents’ unjustified fears of steroid side effects. It is cruel to the child and the family to

forgo topical medication.’
It is very important to use a steroid cream of the right strength. For example, applying a 1%

hydrocortisone cream (available without prescription) to severe atopic eczema will be of no value.

Similarly, only applying a prescribed cream occasionally, or only once a day when the doctor said three

times a day, will mean that the rash never really succumbs to the treatment.
Keeping old tubes of steroid cream in the bathroom cabinet, and using these rather than the newly

prescribed cream, is another frequent mistake. If the earlier prescription was for a weaker steroid

cream, that is not quite up to the job, you won’t get the symptoms under control.
Inadequate treatment means that the rash goes on longer, so you probably apply more steroid in the long

run – which exposes you to a greater risk of local side effects. It is far better to use a moderately

strong steroid cream for a short period of time and get the inflammation fully under control.
Remember that steroid creams are absorbed far more effectively immediately after a bath or shower, so

this is a good time to apply them (see p. 48).
Don’t stop using steroid creams too soon. The skin looks healthy and happy long before it is completely

healed underneath. You must continue until the ‘hidden healing’ has occurred. As a rough guide, the

point when the skin looks good is just the halfway point: so the steroid creams should be continued for

the same length of time again. If it took three weeks to get to the point where the skin looks fine,

then you should go on applying the steroid creams for another three weeks after that.
Generally speaking, it is a good idea to phase out steroid creams slowly, especially after using them

for a long period of time. Stopping abruptly may cause the rash to flare up again –this is called a

rebound effect.
Once you have atopic eczema under good control, you will still need some steroid cream at home for

dealing with relapses. As soon as you notice any rough, itchy skin, apply the cream twice daily for

three days, then once daily for another three days. This should be enough to curb the outbreak of

eczema before it really gets going.
Side effects
To assess the risk of side effects from your steroid cream or oirtment, you need to know how strong it

is. Four grades are recognised: mild (corresponding to non-prescription hydrocortisone cream),

moderately potent, potent and very potent. Ask your doctor or pharmacist which grade corresponds to

your cream, so that you can make sense of the information given below.
Unfortunately, if steroid creams are not used correctly, there are some quite serious local side

effects. Any steroid cream that is strong enough to work is also strong enough to produce side effects

if over-used, so this is a delicate balancing act. The main local side effects are thinning of the skin

and striae (stretch marks). Teenagers and pregnant women are particularly susceptible to stretch marks

if using steroid creams.
It is important to take care because these side effects can be irreversible. The stretch marks, for

example, may fade in time but never entirely disappear. Sustained over-use of steroid creams can

produce permanent thinning of the skin. Thinning of the ski on the face may produce redness, with small

blood vessels shoving through. The fingertips may develop painful cracks.
Note that these side effects can come on very gradually.. Some may be mistaken for symptoms of the

disease itself.
Other local side effects may include an outbreak of spots that look rather like acne. Increased

hairiness or change in skin colour are also possible. Fortunately these effects are reversible.
To avoid side effects, follow the instructions for using steroid creams carefully, and don’t apply too

much or too often. If you have not been given clear instructions by your doctor on the quantity to use,

go back and ask for more information. Ideally, you should actually be shown the correct amount of the

cream to use each time. Remember to wash your fingers after applying steroid creams
If potent or very potent steroid creams are slapped on W& abandon, enough is absorbed into the

bloodstream to produce systemic side effects, comparable to those that can occur with steroid tablets

(see p. 142).
With very potent steroid creams, used for a long period of time, there is some risk of slight systemic

side effects even though the instructions for use are carefully followed. Young children more

susceptible. Bear in mind that covering the skin with cages after applying the cream increases the

amount absorbed into the bloodstream. The degree of adrenal suppression caused by using the cream (see

p. 142) is probably going to remain unnoticed in everyday life, but a major illness, accident,

childbirth or a surgical operation might reveal the problem – so tell medical what you have been using.
Different areas of the body respond differently to steroids creams. The skin of the face, and within

skin folds.
sensitive and generally requires a lower-strength cream, while the palms of the hands and the soles of

the feet require a higher strength. The genitals and the area around the anus are particularly

sensitive, and can become permanently damaged (and then a source of intense discomfort) by strong

steroid creams: some dermatologists recommend using nothing stronger than 1 % hydrocortisone.
Make sure you see your doctor regularly when using steroid creams continuously, especially if:
•    you are using very potent steroid cream
•    you are applying potent or moderately potent steroid cream over more than 20% of your body for

more than a month
•    you are applying potent steroid cream to a baby or young child.
The vehicle – the cream or ointment base in which the steroid is carried – is important because

sensitivity reactions can occur to certain of its ingredients (see p. 45). Eczema sufferers can even

become sensitised to the steroid itself, and this problem is difficult to diagnose because patch tests

with steroids often give false negatives (see box on p. 91). If you are not getting better, ask the

doctor if this could be the explanation. (If a rash gets worse and starts to spread when you begin

using steroid creams, go back and see the doctor very promptly – you may have an infection called

tinea, or ringworm, which flourishes all the more when steroid creams are applied.)
Tacrolimus and pimecrolimus
These are new treatments for atopic eczema. They are not steroids, but are covered here because they

are an alternative to steroid creams and ointments, and if you are comparing the two treatments it may

help to have the information on them side-by-side.
Tacrolimus ointment (brand name Protopic) is for the treatment of moderate to severe atopic eczema, and

pimecrolimus ointment (brand name Elidel) is for milder atopic eczema, especially in children.
These drugs are immunomodulatory rather than immune-suppressive – they adjust the balance of immune

reactions in the
skin. Unlike with steroid creams, there is no risk of thinning the skin, so they can be used on

delicate areas like the face and eyelids.
These treatments are generally used for patients who are not getting better with moisturisers and

steroid creams. Because they cost so much more (about ten times as much as topical steroid treatment),

and since much of the fear of steroid creams is unfounded, doctors are reluctant to prescribe

tacrolimus ointment ,on demand’. With time, the cost of these treatments may fall.
One important advantage of tacrolimus and pimecrolimus ointments is that they may have good effects

that persist after you have stopped using them. And the benefits are cumulative: in one trial where

babies with atopic eczema were treated with pimecrolimus ointment on an as-needed basis, most had fewer

and fewer flare-ups as the months went by. This was not true of babies being treated with steroid

cream.
As with topical steroids, the effect of tacrolimus and pimecrolimus on infections such as

Staphylococcus aureus is surprisingly beneficial: the enormous improvement in the surface structure of

the skin keeps bacteria out. But heavily infected skin should be thoroughly treated with antibiotics

before you start. While using the ointment, watch out for any signs of infection, especially herpes

(see p. 44), and see your doctor immediately.
Minimise your exposure to UV light – in sunlight and sunlamps – because of the tendency of UV to

provoke skin cancers. With the dampening effect that tacrolimus has on the immune system, the risk of

skin cancers may be a little higher.
Don’t apply anything else to the skin (not even moisturisers) within two hours of putting on the

tacrolimus ointment – they dilute the treatment too much. And don’t apply tacrolimus ointment

underneath bandages or other dressings.
Side effects
A few patients find that, while using tacrolimus ointment, skin in areas not being treated actually

gets worse. Talk to your doctor if this happens. Other possible side effects include stinging and

burning when applied, or redness. These are nothing to worry about, and usually lessen with time.
