estramustine A compound of oestradiol and inustine, designed to release mustinc at oestrogen-receptor sites. It has a more localized action and so causes less myelodepression. It is used mainly in prostatic carcinoma, especially when resistant to other therapy.
Dose: 0.56-1.4 g daily. It should not be taken with food or milk products. Side-effects include gastrointestinal disturbances, nausea and gynaccomastia. (Fstracyt). See page 122 and Table 8.
ethacrynic acid A loop diuretic with a rapid and intense action used mainly in oliguria due to renal failure.
Dose: 50 ing daily initially, increased as required up to a maximum of400rng daily or on alternate days. Ethacrynic acid is also given by slow i.v. iniection in doses of 50-100 mg in acute or refractory conditions. Side-effects include nausea, diarrhoea and deafness. Some hypotension may occur initially. (Edecrin).
ethambutol An antitubercular drug.
Dose: 15 mg/kg daily, together with i i lo i i ipic in or isoniazid. Lower doses should be given in renal damage. It may cause visual disturbances with loss of acuity, but recovery is usually complete on withdrawal of the drug. (Myarnbutol). See page 170 and Table 31.
ethamsylate A haemostatic used in the prophylaxis and treatment of periventricular haemorrhage in low birth-weight infants.
Dose: 12.5 mg/kg by injection 6-hourly within 2 hours of birth and continued for 4 days. It is also used orally in menorrhagia. Dose: 2g daily. (Dicynene).
ethanolamine oleate A sclerosing agent used for varicose veins and bleeding oesophageal varices.
Dose: by local i.v. injection, 2-5 nil.
ether A colourless inflammable liquid, once widely used as a general anaesthetic but now replaced by halothane.

Let’s hope it never happens - but if it does, knowing what to do could make the difference between surviving and not surviving. The sensible thing is to read these pages - or whichever parts are relevant to you or your child - before you encounter an emergency. It is often helpful to rehearse the procedure in your mind and actually imagine yourself going through the actions described here.
Find out in advance what the local ambulance service is like, and ask your GP for advice about who to contact in an emergency. (If you have latex allergy, check in advance that all local ambulances carry a latex-free kit.) These are the options:
• Call your GP.If the doctor is nearby and the hospital or ambulance station a long way off, this may be the best decision. Doctors in rural areas may have supplies of adrenaline for emergency treatment, and oxygen for those suffering a severe asthma attack.
• Call an ambulance. Where the local ambulance service is dependable, this is always the best option. The ambulance crew will have adrenaline and oxygen.
• Go by car or taxi to the nearest hospital
emergency department. This is not usually a
good plan, because your condition may quick-
ly get worse, and you have no emergency
treatment available. But there may be situa-
tions where it is a sensible decision. Emergencies can occur when you are away on holiday or business. Never stay anywhere without a phone – check that it is working as soon as you arrive. Make sure you have the number of a local doctor and know where the nearest hospital is. A remote holiday cottage can be a dangerous place to suffer an asthma attack or anaphylactic shock.
Anaphylactic shock
This is an extremely serious emergency, requiring immediate medical help. The signs of anaphylactic shock are listed on p.58. In the case of food allergy, there are additional signs in the mouth, lips and throat (see p. 62). Use adrenaline (epinephrine) straight away if you have it – but get emergency medical help as well. With injectable adrenaline (an EpiPen or Anapen – see p. 150), remove the cap and jab firmly into the outer thigh, going straight through any clothing. Never inject into any other part of the body – this can be dangerous.
If you have an adrenaline inhaler (see pp. 155-6) you can use this first to treat symptoms in the mouth, throat and airways, and then use the injector if you still have symptoms. (Improvise a spacer – see p. 100 – if there is difficulty in inhaling the adrenaline.) Anyone whose reactions tend to be severe should use the injector first and follow up with the inhaler if necessary. Overdosing with adrenaline is possible, and can be fatal, but using the inhaler as well as the injector is safe as long as you don’t have a heart condition (see pp. 155-6).
If you do not improve after using the injector, a second one can be used, 10-15 minutes later.
In situations where medical help is not yet available and the symptoms are not abating, another shot of adrenaline can be given every 15-20 minutes. But the maximum number of shots recommended by your doctor should never be exceeded. Keep count of how many you’ve had, and tell medical staff.
An asthmatic who does not have an adrenaline inhaler can use a beta-2 reliever inhaler such as Ventolin (see p. 152) as well as the adrenaline injection, although it probably won’t help very much.
Suppose you know for sure that you have encountered your allergen, but you don’t have any symptoms yet? In Britain, the usual advice is to wait for symptoms, but doctors in the United States say go ahead and use the adrenaline injector if you have reacted very badly in the past. In general, for people with no other health problems, it is better to give an adrenaline injection which isn’t needed than to delay giving one that is needed. Delaying the use of the injector may mean that the reaction gets out of control. Some people put off using the injector because they think it should be saved for when they ‘really need it’. In fact the adrenaline works just as well if you have used it on previous occasions.
Following anaphylactic shock, you should be kept in hospital for 6-12 hours even when everything seems fine. Attacks have recurred as much as eight hours later. Corticosteroids reduce the chance of this happening – ask if these have been given. If you are discharged early and it is a long journey home, consider waiting in the hospital, or nearby, until eight hours after the original reaction.
First aid for anaphylactic shock
A badly swollen tongue or throat can cause suffocation. If there is visible swelling and the person is unconscious or turning blue, try to keep the top of the trachea (the main airway leading from the throat) open. Use the handle of a spoon – one that has very smooth edges. Slide it carefully over the top of the tongue and into the throat. Press down gently but firmly to open the airway.
Someone who is feeling faint or dizzy, or losing consciousness, or (in the case of a child) becoming very pale and floppy, may be suffering from a dangerous drop in blood pressure. He or she is more at risk of a fatal collapse if in an upright position, because not enough blood is reaching the heart. The worst thing is to stand up suddenly, or to move (or be moved) quickly from a lying to a sitting position –death can follow within seconds. The best thing is to lie down, preferably with the legs resting on cushions or a stool so that they are above the torso, and with the arms raised above the chest. Adrenaline can be given while in this position. A stretcher should be used to get the patient to an ambulance.
Latex allergy and emergency treatment
If you have anaphylaxis due to latex allergy, going to hospital can be alarming, as you may suffer further reactions to latex gloves or equipment. Some patients with latex allergy have had such bad experiences in ambulances and hospitals that they become fearful of using their adrenaline injector, since this means they must go to the hospital afterwards. They delay using the injector, which makes the situation worse. Some doctors are now giving such patients all the medicines and training they need to manage their anaphylactic shock themselves, so that they don’t need to attend hospital.
A person who has lost consciousness should be lying down on their side in case they are sick (this reduces the chance of them inhaling their vomit). The same goes for anyone who feels nauseous.
On the other hand, if the major problem at the outset is difficulty in breathing (as it generally is in children) a sitting position is better.
It is unusual for both faintness and severe breathing problems to be present at once. If this occurs, the patient should lie down, and if there is swelling in the throat, a spoon should be used (see left) to keep the airways open.
Insect-sting allergy
If you don’t have an adrenaline injector, get medical help immediately.
If you’ve had a cutaneous systemic reaction (see p. 60) in the past, use the adrenaline injector if there is any difficulty in breathing, hoarseness, stomach cramps, diarrhoea, nausea, faintness, dizziness or confusion. If you are unsure, remember that, unless you have a heart condition, it is usually better to overreact (i.e. use the adrenaline unnecessarily) than under-react.
If you’ve had a severe systemic reaction (i.e. anaphylactic shock) in the past, use an adrenaline injector at the first sign of any reaction other than immediately around the sting.
If there is a honeybee stinger left in the skin, scrape or flick it out sideways using a fingernail, knife blade or credit card – the venom sac is attached and will go on injecting venom for up to 10 minutes if you leave it there.
Don’t try to pull the stinger out – this squeezes the venom sac and pumps more venom into the skin.
Get emergency medical help, and follow the other measures for dealing with anaphylactic shock (see left).
Don’t go alone
If you suffer vomiting or diarrhoea during anaphylaxis, and have to go to the toilet, tell someone to call an ambulance and take someone else with youto the toilet. Do not go in alone and lock the door, in case you collapse.
Asthma attacks
Even those with mild asthma, who have never had a serious attack before, can quite suddenly get into difficulties and require emergency treatment. Don’t be over-anxious about this, because it is unlikely to happen – but do be prepared. Not having your reliever inhaler with you when a severe attack starts is a recipe for disaster – always take it, wherever you go.
Deal with an attack promptly. The sooner you act, the fewer drugs you’ll need in the long run to control the attack. Most asthmatics wait too long and then under-treat their asthma.
The important thing is recognising an asthma attack, and knowing when it is getting out of control. Not all attacks are the same – some come on fast, some come on slowly.
Rapid asthma attacks come on in a matter of hours. You may have been fine all day, but then start to feel very breathless and wheezy, or begin coughing badly. Less than an hour later, despite using the reliever, the breathlessness is worse and it is a struggle to speak or walk across the room. This is a severe attack: don’t delay in getting medical help.
Slow asthma attacks come on over a period of days. At first you are more breathless and wheezy than usual, and your reliever inhaler is not helping much. Asthma wakes you up at night, and you are far more breathless than usual in the morning. This could be the beginning of a severe attack, so don’t delay in getting medical help. If you get to the point where your asthma is disturbing your sleep every night, and in the morning you have difficulty in speaking or walking about, this is a very serious situation – you must see your doctor or go to the hospital now.
A few asthmatics have great difficulty recognising when they are increasingly breathless, and for them, using a peak-flow meter (see p. 97) every day is essential. Indeed, most asthmatics find
Recognising an asthma attack in a very young child
With a young child, these signs indicate a severe asthma attack:
• the nostrils are flared
• the shoulders are unusually high
• the child can say only one or two words between breaths
• the ribs are pushed out, and the spaces between the ribs, and below the chest cage, are sucked in during breathing
• you can hear wheezing (a whistling noise)
• the lips, tongue or fingernails are blue.
If wheezing stops, without any other apparent improvement, this is a very bad sign — it may mean that the airways are now so narrow that no air is passing through them. This is called a ’silent chest’, and indicates an urgent need for medical attention.
that monitoring peak flow is a valuable way of spotting attacks in advance. However, if your peak flow seems normal, and yet you feel breathless and have a tight feeling in your chest, pay attention to your symptoms and get medical help.
Your response to your reliever inhaler is another helpful sign assessing asthma attacks. Things are serious if:
• the reliever inhaler does not seem to be working at all within 10 minutes of taking a puff
• it does not work as well as usual
• it works, but the effect wears off in less than three hours. If you have an asthmatic child, give everyone who normally takes care of the child detailed written instructions for recognising and dealing with an asthma attack. People forget verbal instructions especially in an emergency. A child who is exhausted or upset c. an attack should always be given medical care.
Taking action
If your reliever inhaler is not working well (see above), take another puff to open up your airways – and then take further action. as described below.
If you seem to be in the early stages of a slow asthma attack check your management plan, and if your peak flow has fallen below the recommended level, double the dose of inhaled steroids (twice as many puffs each time) now. Add any other medicines (e.g. steroid tablets) as recommended by the management plan.
Those who don’t have a peak-flow meter or management plan should double the dose of inhaled steroids and make an urgent appointment to see the doctor.
If you are suffering a rapid attack, or a slow attack that has got out of control, you need emergency medical help. Ring for an ambulance, ring your doctor, or go to the hospital – the ideal course of action will vary, depending on where you live (see p. 98).
Use your reliever inhaler until medical help arrives. You can take a puff every 5-10 minutes if needed, but keep a count of how many puffs you’ve had and stop after 30. Some doctors suggest taking up to 30 puffs all at once. (If you have a heart condition, this dose might be dangerous: follow your doctor’s advice.)
If it is difficult to inhale, use a spacer – this can make all the difference, especially for children.
You can improvise a spacer from a plastic cup, a plastic bottle, or a paper bag. Make a hole in the bottom of the cup or bottle, or in one corner of the paper bag, and insert the mouthpiece of the inhaler here. The open end of the cup, bottle or bag goes in or over the mouth – with the bag, you have to bunch it up and hold it around the mouth. Squirt the inhaler repeatedly into the improvised spacer, while breathing steadily in and out.
The six golden rules for asthma attacks
• Breathe as slowly as possible and concentrate on breathing out, not on breathing in. Exhale as fully as you can and your in-breath will follow automatically.
• Never panic – if you do, you may start hyperventilating, and this makes matters much worse (see p. 226). Panicky parents are the worst possible thing for an asthmatic child during an attack.
• Adopt a position that makes breathing as easy as possible. Propping your arms up at about shoulder height can help – for example, sit back-to-front on a dining chair, with your arms folded and resting on the back. Or put pillows on a table, sit in an upright chair, and rest your head and arms on the pillows. Don’t lie down, as this makes matters worse. Open a window, as long as the air outside is not cold, polluted or loaded with pollen.
• Avoid factors that can make an asthma attack worse, for example, vigorous activity, cold air, irritants and allergens.
• Drink plenty of water, fruit juice or other liquids as a lot of water is lost through the surface of the airways during an asthma attack, and you can become dehydrated.
• Don’t take anything to help you sleep, even herbal pills. If your asthma gets worse during the night, you need to wake up so that you can get more air.
After an attack
Asthmatics who have suffered a severe attack are occasionally sent home from hospital before they are completely better. A few people have died as a result of being discharged too soon. So if you feel breathless or otherwise unwell after you leave hospital, don’t hesitate to go back – or seek other medical help.
See your GP or specialist within a few days of any emergency treatment. Don’t be over-confident just after a severe attack – this can be a very vulnerable time. Take more rest than usual and drink plenty of fluids, as you may be dehydrated. Keep taking your preventer inhaler at the increased dose – reducing the dose now could lead to another severe, possibly fatal, attack. Keep taking steroid tablets if you have been given them.
If you produced a lot of mucus during the attack, try to clear it, but without violent coughing. Mucus can sometimes form solid plugs which block small airways. Treatment by a physiotherapist would help, and expectorants – drugs which help loosen mucus –can also be useful (ask your pharmacist about these). Don’t take ordinary cough medicine (see box on p. 163). There are also some breathing exercises which can help to clear mucus (see p. 231).
An asthma attack represents a chance to learn more about preventing asthma – so think about what went wrong. Had you forgotten to take your preventer inhaler regularly? How long is it since you had your medicines reviewed by the doctor or asthma clinic? Have you been using your peak-flow meter daily? Were you exposed to a high dose of allergen or an irritant?
A reaction to aspirin-like drugs
Aspirin sensitivity can begin quite suddenly in someone who has previously taken aspirin without trouble. If you have unexplained chronic urticaria, or polyps in the nose, plus asthma and/or rhinitis, the development of aspirin sensitivity at some time in the future is a distinct possibility (see p. 151).
A sensitivity reaction to aspirin or aspirin-like drugs usually begins between 30 minutes and two hours after the drug is taken. You will have some or all of these symptoms:
• a runny or badly blocked nose, and red eyes
• a feeling of warmth, flushing and sweating
• a general rash
• a sensation of tightness in the chest, a dry cough, increasing breathlessness
• malaise and exhaustion
• vomiting or diarrhoea
• swelling (angioedema) and/or nettle rash (urticaria). If you have such symptoms get emergency medical help immediately because the reaction can quickly develop into severe asthma, shock, collapse and unconsciousness.
If you have asthma, use your reliever inhaler as much as required (up to 30 puffs) until medical help arrives. Anyone who has an adrenaline (epinephrine) auto-injector, or an adrenaline inhaler, can use this as well – up to 30 puffs of the inhaler, or whatever maximum dose is given in the instructions. Tell the ambulance crew and doctors exactly what you have taken.

Tony had suffered from hayfever since childhood but rarely took any medicines. Outside the grass-pollen season, he was fine, free of allergies and very fit. Then, when he was 35 he bought a run-down cottage in the country. The cottage was very damp and dirty.
The previous owner of the cottage, an elderly man, had died, and everything was much as he had left it. Tony moved in with his wife in late summer, and they began pulling out all the old carpets and furniture. Many of the windows would not open and there were dank musty cupboards and attics to be cleared. Dust filled the air – and Tony’s nose. He began to sneeze a little and within a few days he had a strange and unfamiliar feeling of tightness in his chest. During the following weeks, harvesting began in the surrounding fields, with several huge combine-harvesters working away all day and night. Tony noticed that, when out of doors, his eyes began to stream and the tightness in his chest became more noticeable. A few more days passed, and Tony found it harder to breathe, so he reluctantly went to see the doctor. The diagnosis was asthma. Skin-prick tests showed that Tony had allergic reactions to house-dust mite and moulds.
Tony’s case shows how someone who is already sensitised to an allergen – pollen in this case – may be vulnerable to developing new sensitivities, and new symptoms. It was almost certainly the dust mite and mould spores in the cottage that sparked off the trouble, followed by the mould spores from the cereal leaves, dispersed during harvesting.
For people with a tendency to allergies, the dangers of heavy exposure to potential allergens are something to bear in mind. It is surprising how many people with asthma had their first major attack while away from home, sleeping on an old sofa or in a friend’s dusty spare room. The dose of dust-mite allergen that you get from an ancient mattress or eiderdown can be massive.
Managing your allergy symptoms
As well as avoiding the development of new allergies, you need to manage your existing symptoms, and make sure that they interfere with your life as little as possible. For this you need good information and advice, support from your doctor, optimal drug treatment, and careful avoidance of your allergens.
Quite often people have all the information and drug treatment they need, but they still don’t stay on top of their health problems. There can be two distinct reasons for this: either they are not wholehearted about wanting to be well (ambivalence) – or they have never really accepted that they are ill (denial).
Ambivalence
Sometimes being ill has certain benefits – or being entirely well has certain disadvantages. Our state of health determines how people treat us, especially within the family, and the expectations people have of us. It may be comforting to be ill because others are more supportive then, or it may be less risky, because we are not forced to try things (such as sports or other physical activities) at which we might fail or look foolish. Being ill as a child often sets up a pattern for how we interact with the world, which revolves around caution, the comforts of familiarity, and holding back from new situations.
These habitual patterns can survive in the mind long after any real advantages have evaporated. Many people become stuck with a way of thinking and living where ill-health is a cornerstone of their existence. Doctors at the Chelsea and Westminster Hospital in London, who have developed a radical programme for treating atopic eczema (see pp. 46-8), have noticed this in their patients. ‘Old habits die hard and living with a little bit of eczema is a very tempting prospect for many patients, rather than clearing the skin completely…. As atopic skin disease begins for many in the first year of life, causing sometimes understandable alarm and despondency in the parents, the child learns how relevant their condition can be in their relationship with the external world, and with their parents in particular. Before they are able to speak, they have a powerful means of gaining parental attention which can have long-standing effects in the development of their personality. For some, to live without eczema is understandably a daunting prospect. This can be consciously appreciated and spontaneous-y referred to by some patients, while for others the issue will be buried from view, deep in their unconscious.’
If any of this rings bells with you, try to tackle the problem at source. Such mental blocks are not immovable. Indeed, simply recognising that the block is there can start to change things for some people.
Others may need professional help to overcome these longstanding habits of mind. Counselling or cognitive therapy can be very valuable, and your doctor may be able to help in locating a suitably qualified person for this.
Denial
At the opposite end of the spectrum are those who want to deny that they have any kind of health problem. Often these people cannot quite accept that they have a long-term disease, such as eczema or asthma, so they forget to take their drugs, apply creams to their skin, or carry their inhalers. Ironically, these people frequently wind up having far more trouble with their allergies than they need to, and a very poor quality of life, simply because they neglect preventive treatments.
To be really well, you first have to admit that you do have allergies, and then sort out your conflicting feelings about what this means. Again, counselling, cognitive therapy or some other kind of psychotherapy can be helpful.
Dealing with doctors
The decisions that your doctor makes about your treatment are ones in which you should be fully involved. Quite a few allergy patients don’t feel happy about their doctor’s treatment plan, but they never say so to the doctor’s face.
The usual pattern is to accept what the doctor prescribes without any argument, but then halve the dose of tablets, or only put the cream on once a day instead of twice, or not use the Inhaler at all. Some people stop and start their drugs in a random way because they never quite make up their minds about whether drugs are a good thing or not.
This approach to allergies invariably leads to worsening symptoms. The risks are greatest with complex problems such as
atopic eczema or chronic sinusitis, where a vicious circle can easily be set up if the disease is not brought under control, and for those with a life-threatening condition such as asthma. In the case of asthma, neglecting preventative treatment can be fatal.
It is far better to say what you think in the surgery, and discuss any misgivings you may have about drugs with the doctor. That way you can agree on a treatment regime that you are prepared to stick to – which may or may not involve drugs. Most doctors would far prefer a little plain speaking at the outset to having a patient who is half-hearted about following the treatment plan and never really improves.
A more serious form of communication breakdown occurs when a doctor stops believing what a particular patient says. This usually occurs because the doctor has decided that some or all of a patient’s symptoms are due to psychological rather than physical causes. (This is far more likely to happen to those with intolerance or unusual forms of allergic reaction than to those with classical allergic diseases.) Sometimes doctors say what they think, but often they don’t – they just start treating the symptoms in a different way, or acting impatiently, or saying rather puzzling things that leave the patient trying to guess what is going on.
If you find yourself in such a situation, the main thing to do is stay very calm and be very rational. Getting upset, or challenging the doctor’s opinion in a manner that seems at all aggressive, instantly confirms the ‘psychological’ diagnosis. Unfortunately, insisting firmly that the symptoms are not psychological also confirms the diagnosis as far as many doctors are concerned (see p. 237) which can be extremely frustrating. To begin with, deal with the situation by informing yourself about your illness. Be tactful and patient but persistent with the doctor, trying all the time to keep the relationship pleasant and the channels of communication open. If, after giving it a fair try for some weeks or months, this approach isn’t working, you should look into the possibility of changing doctors (see p. 88).
Emergency alerts
An emergency alert bracelet or pendant should be worn by anyone who:
• is allergic to latex rubber, or to drugs such as penicillin
• has a severe allergy to insect stings
• suffers from exercise-induced anaphylaxis, or anaphylactic shock as a result of food allergy
• has very severe asthma attacks.
Key information is engraved on the bracelet, along with a telephone number which gives medical staff access to a computer database containing vital medical data about you. This valuable service is provided by a non-profit-making company called Medic Alert.
As everyone knows, a little knowledge is a dangerous thing. You can use the information in this book to help yourself, but it’s important to remember that there is no substitute for the comprehensive understanding of the human body that your doctor gained during many long years at medical school. Always check with your doctor before changing your diet, stopping your drugs, practising breathing exercises, taking a non-prescription medicine or trying any other experimental treatment.
The information about disease, diagnosis and treatment in this book falls into four categories:
• basic information about the disease that no doctor would disagree with
• the findings of new research, or research that has not become widely known, but which falls within the accepted medical model of the disease concerned. Your doctor may not know about some of this research (there is a terrifying amount of new information bombarding doctors every week, and no one can keep up with it all) but he or she won’t find it unbelievable.
• evidence from research that is entirely valid, but which is widely ignored or dismissed because it falls outside the accepted medical model of the disease concerned (see pp. 86-7)
• information based on the repeated observations of doctors, or of patients – this does not amount to scientifically valid evidence, but it’s included here if it seems plausible and if it could be useful to some readers.
You should be able to tell, from the context in which it is presented, which category any item of information falls into. When talking to your doctor about items that belong in the last two categories above, be prepared for a certain amount of scepticism or possibly outright dismissal.
The important thing to ask the doctor is if there is good reason why you should not try the suggested measures, in addition to your usual treatment – is there any risk involved, given your particular state of health? Make it clear that you want to try the additional treatment with an open mind and will drop it if it is not helping. Ask for the doctor’s help in assessing the effects of the treatment objectively.
Managing asthma
Of all the diseases described in this book, asthma is among the most difficult to live with, especially severe asthma. Learn to recognise asthma symptoms before they get out of hand, and take immediate action.
Studies of patients who die from asthma attacks find that the deaths could, in almost all cases, have been prevented. Factors contributing to fatal attacks include:
• heavy exposure to allergens just before the asthma attack
• cigarette smoking
• failure to use preventer drugs
• repeat prescriptions for inhalers being given without the patient seeing a doctor
• delays in seeing an asthma specialist
• depression in the asthmatic leading to neglect of treatment.
For the day-to-day management of asthma, you should have a written management plan prepared by your doctor or asthma nurse.
This should tell you how often to take your drugs under normal circumstances, and what to do if your symptoms change or you develop a cold or chest infection. The actual brand names of your drugs (or the colour of the inhaler) should be included on the management plan. Assuming you have a peak-flow meter – and you really should have one –specific peak-flow values should be included on your management plan, with instructions for how to respond if your peak flow falls to these levels.
Your plan should tell you how to recognise a severe attack coming on, and what to do at the various stages of the attack. (This personal management plan is specifically geared to you or your child. Although pp. 100-101 give generalised advice, your own plan is invaluable.)
Be sure that you know exactly how the advice in the plan relates to the sort of real-life situations you experience. No matter how good your plan, real life can sometimes be far more complex than anyone anticipates, so there may be times when it is difficult to know what to do. When this occurs, make a note of the situation, and the reasons why you are unsure how to implement the plan. Call your doctor immediately if your asthma is getting worse, and get the asthma attack under control. Save your notes and, at the next opportunity, check with the doctor what you should have done in those circumstances. This will help you to build up your detailed knowledge of how to manage your asthma, or that of your child.
Research shows that asthmatics can, with training, develop a greater awareness of how narrow their airways are – this helps you to detect worsening asthma before things get too serious. You can train yourself in this art by guessing what your peak flow will be and writing your guess down before you use your peak-flow meter (see right) each day. Over a period of weeks, you should find your guesses getting closer to the true value.
A key part of asthma control is having everything with you that you need in case of an attack. It’s tedious, but you have to do it. You should take your reliever inhaler with you wherever you go. Those with severe asthma can also benefit from carrying a collapsible spacer (ask your pharmacist or see p. 255 for contact details of suppliers).
For a long day out, or a stay away from home, check that you also have:
• your management plan
• your peak-flow meter
• your preventer inhaler
• steroid tablets, if you sometimes need these
• your doctor’s phone number.
A little lateral thinking may be needed regarding the problem of carrying all this kit around. One asthmatic friend of mine carries his inhalers in a trendy-looking camera bag that goes everywhere with him. Mothers of asthmatic children have solved the problem by making an ‘inhaler pouch’ from a sunglasses case and attaching it to a favourite belt or by enlarging the pocket in a teenager’s jacket to accommodate inhalers.
Anyone with severe allergies to food or insect stings should take similar steps, so that carrying their auto-injector everywhere is a simple matter.
Peak-flow meters
A peak-flow meter can detect narrowing of your airways – the beginnings of an asthma attack – before there are any obvious symptoms. It measures the maximum speed at which you can force air out of your lungs. The signs of worsening asthma include:
• a morning reading which is less than 75% of the evening reading
• average readings less than 75% of your best-ever reading. (If they get to less than 50% of your best reading, this is a severe and possibly life-threatening attack.)
To use a peak-flow meter:
• push the pointer to zero and hold the meter horizontally
• keep your fingers away from the scale and the pointer
• breathe normally before you start
• stand up and take a deep breath, but don’t puff your cheeks out and don’t hold your breath before you blow
• seal your lips tightly around the mouthpiece
• blow hard into the meter, as if blowing out candles on a birthday cake; don’t move your tongue while doing this
• repeat three times, and record the highest reading of the three.
You must learn how to use a peak-flow meter from your doctor or asthma nurse, who should also check your technique regularly – it is very easy to get into bad habits.

Drugs for Asthma
The drug treatment of asthma is far more complex than for any other allergic disease. Drugs prescribed for asthma fall into two basic categories: those that open up the airways by relaxing the airway muscles, called relievers, and those that treat the inflammation in the lining of the airways, called preventers. The former offer a ‘quick fix’ - like taking an aspirin when you have a headache. Just as the actual cause of the headache is not treated by an aspirin, so the actual cause of the asthma attack is not addressed by relievers. Preventers, on the other hand, tackle the basic problem - the inflammation that triggers the contraction of the airway muscles (see p. 36).
In the past ten years, there has been a quiet revolution in asthma treatment, with far more people being given preventer inhalers, usually low-dose steroids. The aim is to get the airways in better condition, with the inflammation thoroughly damped down, so that the airway muscles don’t go into spasm. The ultimate objective is to make people far less reliant on reliever inhalers, because the potential hazards of over-using them are now realised.
The details of modern asthma management, and the different approaches used, are described on p. 160, following the discussion of the main types of drug used for asthma treatment.
Beta-2 relievers (beta-agonists)
Our airways open up when we produce adrenaline. This is the body’s natural response to feeling angry or frightened. The adrenaline widens the airways so that we can run faster or fight more vigorously.
Adrenaline (epinephrine), given as a drug, was among the earliest treatments for asthma. However, it also stimulates the heart to beat faster and raises
the blood pressure. While it is useful for emergency treatment (see p. 155) the side effects make it too hazardous for routine use.
The beta-2 relievers work by mimicking adrenaline – they bind to the same receptors in the airways, the beta-2 receptors. Binding to these receptors stimulates the airway muscles to relax, so that the airways open up.
In other respects, the beta-2 relievers are not like adrenaline. Clever chemical manipulation has made them sufficiently different from adrenaline to have little effect on the heart and other organs, when taken at normal doses.
Beta-2 relievers are best taken by inhalation. Although tablets and syrup are available these are far more likely to bring on side effects, because the dose needed is so much bigger.
Inhaled beta-2 relievers target the drug directly on the airways, so the dose can be smaller. They also have the great advantage of taking effect soon after being inhaled, and giving full relief from airway narrowing within 10-15 minutes.
There are two different kinds of beta-2 relievers:
•    the traditional short-acting beta-2 relievers whose effects last for 3-6 hours (usually about four). The modern consensus is that these should be used only when needed, not taken routinely.
•    the newer long-acting beta-2 relievers, which last up to 12 hours. These drugs are prescribed for more severe forms of asthma (see p. 154), and are generally used routinely, twice a day.
A key question for asthma sufferers is: How often can short-acting beta-2 relievers be used? Ideas about this have changed considerably over the last 20 years, and no doctor would now want to have patients using a Ventolin inhaler five, six or more times a day - something that was quite common in the past. This level of need for beta-2 relievers indicates that the asthma is poorly controlled and requires treatment with a preventer, to quell the inflammation in the airways.
Detailed policy on beta-2 relievers still varies from one part of the world to another. British guidelines state that anyone who needs to use a short-acting beta-2 reliever more than once a day, or who suffers from nocturnal asthma, should be given a preventer as well. The international guideline is more stringent: if a short-acting beta-2 reliever is needed more than three times a week, a preventer should also be prescribed.
How safe are these drugs in the long term? The cause of the big re-think on beta-2 relievers was an epidemic of asthma-related deaths in New Zealand between 1976 and 1988. The death rate from severe asthma attacks was 2-4 times its previous level for a while, and over a thousand New Zealanders died in the epidemic.
There has been a huge controversy over what exactly caused these deaths. Most researchers now agree that the main cause was a new brand of inhaler that delivered a double dose of the drug fenoterol, a short-acting beta-2 reliever with a very powerful effect on the airways and quite high levels of side effects involving the heart. The same brand of inhaler may have been linked to increased death rates in Canada and Germany.
Research suggests that the problem was greatest in New Zealand because sales of the new inhaler were highest there, and because many patients got their inhalers through repeat prescriptions. As a result, people whose asthma was deteriorating badly were not seen by a doctor and were using large amounts of beta-2 reliever, rather than taking preventer drugs. This is now believed to be a major cause of asthma deaths. There are three separate factors involved:
•    The beta-2 reliever covers up the effects of the severe inflammation of the airways. People feel reasonably well, because the reliever is opening up their airways, and don’t realise just how bad their asthma really is. The untreated inflammation in the airways can eventually lead to a very serious, and potentially fatal, asthma attack.
•    The short-acting beta-2 reliever, used regularly, makes the airways more sensitive to exercise, and to allergens such as dust mite or pollen. This means that an asthmatic who is already allergic to these allergens reacts to them at much lower levels in the air.
•    The airways become less and less responsive to the beta-2 reliever itself, so that when a serious attack occurs, requiring hospital treatment, huge doses of beta-2 reliever are needed to open up the airways. These massive doses carry a risk of serious side effects involving the heart.
The details of the New Zealand epidemic still evoke controversy. Was fenoterol itself, which is stronger than other beta-2 relievers, the cause of the deaths? Or was it just that the inhaler delivered a double dose - would any short-acting beta-2 reliever be dangerous at twice the normal dose? Or was it over-use of all beta-2 relievers and lack of preventer drugs?
Some common brand names
Common brand names include:
short-acting beta-2 relievers in inhalers - Aerolin, Airomir, Bricanyl, Ventolin short-acting beta-2 relievers in tablets - Bambec, Bricanyl, Volmax short-acting beta-2 relievers in syrup - Monovent, Ventolin
long-acting beta-2 relievers in inhalers - Bambec, Foradil, Oxis, Serevent
Until this is resolved, safety-conscious asthmatics may want to assume that any of these possibilities could be correct. An ultra-cautious approach would include:
•    Avoiding fenoterol (it is no longer available in Britain, except in the Duovent inhaler, combined with an anti -choli nerg ic drug)
•    Not using double-dose inhalers of any beta-2 reliever (i.e. inhalers that deliver 200mcg/ micrograms per puff)
•    Not routinely taking two puffs of a single-dose inhaler (check with your doctor if you have been told to take two puffs)
•    Using any short-acting beta-2 reliever only I as needed’ – which should be once a day or less according to British guidelines. Note that, with this level of use, there is absolutely no risk from these drugs: it is only regular over-use that is damaging and dangerous.
•    Using a peak-flow meter and ensuring that you are assessed regularly by your doctor
•    Always taking your preventer medication as prescribed.
Since about 1990, the death rate from asthma has been falling, particularly in countries with a policy of reducing use of beta-2 relievers, and increasing inhaled steroids. The death rate in New Zealand is now the lowest it has been for 50 years, and at the same level as in other Western countries.
Unnecessary alarm
While investigating the causes of the New Zealand epidemic, medical researchers discovered that patients inhaling a short-acting beta-2 reliever four times a day had more irritable airways after just two weeks. Their airways were also less responsive to the drug, even after this brief period of use.
Some researchers began to ask if the asthma epidemic itself – the increasing number of cases of asthma – could actually be due to these drugs. Maybe children with mild wheezing, which might have cleared up if left untreated (and which would have gone untreated in the past) were becoming full-blown asthmatics because they were now using beta-2 inhalers?
Many doctors became very concerned about these questions, and a leading medical journal
published an article with the provocative title: ‘Worldwide worsening wheezing – is the cure the cause?’ That was in 1992. Since then, much more research has been done, and it is clear that this particular fear about beta-2 relievers was unfounded.
Unfortunately, there are a few books and other publications around that are spreading unnecessary alarm about these drugs by reporting the debate as it was in 1992. They have taken up that question ‘Is the cure the cause?’, assumed that the answer is ‘yes’, and ignored all the subsequent research, which shows the opposite.
Beta-2 relievers in severe asthma
A few patients with severe asthma remain breathless and wheezy, even though they are inhaling moderate doses of a steroid preventer every day. Increasing the dose of inhaled steroids does not make a huge difference to their symptoms, and it substantially raises the risk of steroid side effects.
Taking a long-acting beta-2 reliever often works wonders for such patients. These relatively new drugs relax the airway muscles, and go on working for 12 hours or more.
There has obviously been concern about long-acting beta-2 relievers having the same sort of insidious side effects as their short-acting colleagues (see p. 153), and so increasing the likelihood of deaths from asthma. However, studies of people taking these drugs suggest that the risks are minimal. Certainly, long-acting drugs taken twice a day are very much safer than short-acting drugs taken four times a day.
Other studies show that the chemical differences of the long-acting drugs, as well as prolonging their effects, also give them a more complex set of actions in the body. For example, they improve the effect of steroids in calming inflammation, and may even have some small anti-inflammatory effect of their own.
Doctors believe that, for patients with troublesome asthma, the benefits of long-acting beta-2 relievers greatly outweigh the risks. But they should only be used in combination with inhaled steroids. Various other options, such as allergen avoidance and the new anti - leukotriene drugs (see p. 159), should probably be investigated as well.
If you are taking long-acting beta-2 relievers, do use them regularly, once every 12 hours – the good effect gradually builds up with consistent use.
Generally speaking, you should not take additional doses in between. These are not intended for use if you have a sudden asthma attack – your doctor will prescribe a short-acting beta-2 reliever for this. This limitation on the use of long-acting beta-2 relievers is certainly appropriate for salmeterol (which was the first of the long-acting beta-2 relievers to be developed) because it is very slow to take effect on the airways. However, one of the newer long-acting beta-2 relievers, called formoterol, begins to work just as quickly as a short-acting beta-2 reliever. Formoterol could, in theory, be used on an ‘as-needed’ basis to combat asthma attacks. You may want to discuss this possibility with your doctor.
Finally, don’t stop taking your preventer drug (e.g. inhaled steroid or cromoglycate), even if you feel a lot better. Long-acting beta-2 relievers are not a substitute for preventers.
Some patients with very severe asthma need to take regular doses of short-acting beta-2 relievers as well as long-acting beta-2 relievers. You should obviously follow the advice of your asthma specialist closely if you are on this kind of drug regime, and not change anything without approval. However, it might be worth discussing other options, such as anti -leukotriene drugs. In addition, do all you can to combat your asthma in other ways – by reducing allergen exposure, avoiding asthma triggers (see p. 39), and employing various other self-help measures (see p. 41).
Immediate side effects of beta-2 relievers
Minor immediate side effects of these drugs include:
•    headache
•    nervousness, trembling, restlessness, anxiety; children may become more excitable, and some are badly behaved or even aggressive.
•    flushing
•    dry mouth
•    muscle cramps.
These side effects – all of which are due to the resemblance of beta-2 relievers to adrenaline – usually wear off relatively quickly. Some long-acting beta-2 relievers may cause nausea and vomiting.
A pounding heart is usually a relatively minor side effect, but it can be more serious, and should be reported to your doctor.
A few asthmatics find that their airways tighten up when these drugs are inhaled, rather than opening. This is called paradoxical bronchoconstriction. If this happens, stop using the inhaler and see your doctor as soon as you can.
Even more rarely, asthmatics can develop allergic reactions to the drugs, or suffer hallucinations or seizures. Obviously you should stop using the inhaler immediately if you experience side effects of this kind, and should see your doctor.
There can be an interaction between beta-2 relievers and other drugs or medical conditions. Should you need a diuretic, tell the doctor or pharmacist that you are also taking a beta-2 reliever, and ask which diuretics are safe. If you have high blood pressure, a heart problem, or a thyroid condition, make sure the doctor remembers this when prescribing beta-2 relievers.
Adrenaline inhalers
Adrenaline inhalers are for use in emergencies. Technically, they are not available in Britain, but they can be imported under special licence, and your doctor may be persuaded to obtain one for you if he or she thinks it might be useful. They are given to people who have asthma and have sometimes had attacks of anaphylaxis (see p. 58), for example in reaction to food, latex or an insect sting. The inhaler provides prompt emergency treatment for the kind of severe asthma attack that you may experience during anaphylaxis.
You should probably be carrying an adrenaline auto-injector as well, as you may need to use both (see p. 98). Those who usually have fairly mild reactions to their allergen can use the inhaler first, to treat symptoms in the mouth, throat and airways. If other symptoms develop, such as faintness or widespread nettle rash,
Asthma alert
If you ever find that your short-acting beta-2 reliever has no effect within ten minutes, or is needed more than once every four hours, this indicates a serious asthma attack and you need urgent medical help (see p. 100).
During a severe asthma attack, while getting to hospital or waiting for a doctor to arrive, up to 30 puffs of a short-acting beta-2 reliever should be taken as an emergency treatment, to get the airways open. There is a risk of death if you don’t use the reliever fully in this situation. (This emergency dose is safe for almost everyone, but there may be risks if you have a heart condition – get detailed advice from your doctor in advance.)
then the adrenaline injector can be used. Those with a history of more severe reactions should start with the adrenaline injector and then use the inhaler if there are still symptoms in the mouth or airways.
Don’t exceed the maximum number of puffs stated on the canister, as the propellant can cause problems. If you have a heart condition, your doctor will advise you about using this kind of treatment safely - adrenaline can affect the heart.
Ephedrine
Ephedrine and orciprenaline (brand name Alupent) belong to the previous generation of reliever drugs. They are chemically very similar to adrenaline and therefore cause a lot of side effects, especially involving the heart.
These drugs are no longer recommended, and will soon be phased out completely. Some older asthmatics may still be using them, just because they have been on them for years and no one has reviewed their treatment.
If you are taking such drugs, ask your doctor about switching to a newer form of reliever - it will be more effective in treating your asthma, as well as having fewer side effects.
Anti -cho linerg ics
These drugs, also known as anti-muscarinics, are relievers. However, they work in a completely different way from the beta-2 relievers. They block the action of the parasympathetic nervous system, a set of nerves that are the biological equivalent of auto-pilot - working without the intervention of conscious thought. The parasympathetic nervous system has many effects on the body, including keeping the airway muscles nicely toned (see box on p. 235). By blocking the parasympathetic, anticholinergics help the airway muscles to relax.
Anti-cholinergics are taken by inhaler, and require 30-90 minutes to achieve their full effects. They should continue working for 3-6 hours.
Some common brand names
Common brand names of anti-cholinergics include: inhalers – Atrovent, Oxivent
nasal spray - Rinatec
For most asthmatics, especially those with a strong allergic component to their asthma, anti-cholinergics are generally less effective than beta-2 relievers. But they are useful to children under one year, who may not respond to beta-2 relievers. They also have a role where asthma is combined with chronic bronchitis -here the anti -choli nerg ics can sometimes be more effective than beta-2 relievers - and they are particularly useful for asthma with a lot of mucus, because blocking the parasympathetic tends to reduce mucus production. For severe asthmatics, anticholinergics may be combined with beta-2 relievers.
Anti -choli nerg ics should be taken only when needed, not regularly several times a day. If used regularly, they can make the airways more sensitive, just as short-acting beta-2 relievers can (see p. 153).
Side effects
Minor side effects of anti-cholinergics may include a dry mouth, blurred vision, constipation, and irritation of the mouth and throat. A few people suffer nausea or difficulty in passing urine.
Serious side effects are rare. Any increase in the stickiness of the sputum coughed up may be a cause for concern, especially in children. If there is an increase in wheezing or coughing, stop taking the drug and see your doctor.
If you already have glaucoma or prostate problems you should be monitored carefully by your doctor, as these conditions can get worse with anti -choli nerg ic drugs.
When anti -choli nerg ics are used in a nebuliser, it is vital that the mask fits well (see p. 163).
Anti-cholinergics for the nose
Another use for anti-cholinergics is in nasal sprays, for the treatment of vasomotor rhinitis, a non-allergic condition that is frequently mistaken for allergic rhinitis (see p. 29). In this disorder, the constant flow of mucus is caused by a malfunction of the parasympathetic nervous system, which is why anti-cholinergics work well.
