Prescribed For
A wide variety of disorders from rash to cancer, including adrenal disease, adrenal hormone replacement, bursitis, arthritis, severe skin diseases including psoriasis and other rashes, severe or disabling allergies, asthma, drug or serum sickness, attacks of multiple sclerosis, severe respiratory diseases including pneumonitis, blood disorders, gastrointestinal (GI) disease including ulcerative colitis and Crohn’s disease, and inflammation of the nerves, heart, or other organs. Dexamethasone is also used to treat mountain sickness, vomiting, bronchial disease in premature babies, excessive hairiness, and hearing loss associated with bacterial meningitis. Fludrocortisone is used to treat Addison’s disease and for symptomatic orthostatic hypotension. Prednisone is used to improve strength and function of some muscular dystrophy patients. Methylprednisolone is used to decrease mortality in some patients suffering from severe alcoholism and chronic active hepatitis.
General Information
Produced by the adrenal gland, natural corticosteroids are hormones that affect almost every body system. The major dMeyences among corticosteroid drugs are potency and variation in secondary effects, 0OZ10r preference and past experience with a Mftosferoid usually determine which drug to prescribe for a specific disease.
Cautions and Warnings
Do not use an oral corticosteroid if you are allergic or sensitive to any of its ingredients.
Corticosteroids may mask symptoms of an infection. Because these drugs compromise the immune system, new infections may occur during corticosteroid treatment; when this happens, a relatively minor infection that would respond to ordinary treatment can turn serious. Corticosteroids may impair immune response to hepatitis B, prolonging recovery. They may reactivate dormant amebiasis (a parasitic infection). Corticosteroids should not be taken if you have a fungal blood infection, because they can allow the infection to spread more easily. They should be used with caution by people with herpes eye infection, tuberculosis or in any other bacterial, fungal, or viral infections.
Long-term use of any corticosteroid may increase the risk of developing cataracts, glaucoma, or eye infections, especially viral or fungal.
When stopping a corticosteroid, dosage must be reduced gradually under a doctor’s supervision—otherwise you may experience adrenal gland failure.
If you are taking large corticosteroid doses. you should not receive any live virus vaccine because corticosteroids interfere with the body’s reaction to the vaccine.
Hydrocortisone and cortisone may lead to high blood pressure. Other corticosteroids are less likely to affect blood pressure.
Corticosteroids should be used with caution if you have severe kidney disease.
High-dose or long-term corticosteroid therapy may aggravate or worsen stomach ulcers. This may occur when total dosage reaches 1000 mg of prednisone, 150 mg of betamethasone or dexamethasone, 5000 mg of cortisone. 4000 mg of hydrocortisone, 1000 mg of prednisolone, or 800 mg of methylprednisolone.
People who have recently stopped taking a corticosteroid and are going through a period of stress may need small doses of a rapid-acting corticosteroid, such as hydrocortisone, to get them through this period. Call your doctor if you think you might be experiencing this kind of stress reaction.
Use corticosteroids with caution if you have had a recent heart attack or have, Colitis, heart failure, high blood pressure, blood-clotting tendencies, thrombophlebitis, osteoporosis, antibiotic-resistant infections, Cushing’s disease, myasthenia gravis, metastatic cancer, diabetes, underactive thyroid disease, cirrhosis of the liver, or seizure disorders.
corticosteroid psychosis (symptoms include euphoria or feeling “high,” delirium, sleeplessness, mood swings, personality changes, and severe depression) may develop in people taking dosages greater than 40 mg a day of prednisone. These symptoms may also develop with other corticosteroids taken in equivalent doses (see “Usual Dose” for relative equivalencies). Symptoms of corticosteroid psychosis usually develop within 15-30 days of beginning treatment. These symptoms may also be linked to other factors—women and those with a family history of psychosis are more at risk.
Corticosteroids can cause loss of calcium, which may result in bone fractures and aseptic necrosis of the femoral and humorai heads (a condition in which the large bones in the hip degenerate from loss of calcium).
Prednisone may aggravate emotional instability.
Corticosteroids do not cure multiple sclerosis (MS) or slow its progression, though they may speed recovery from attacks of the disease.
. Corticosteroid products often contain tartrazine dyes and sulfite preservatives. Many people are allergic to these chemicals.
Possible Side Effects
✓    Most common: headache, respiratory infections, acne, and bruising.
✓    Common: water retention (swollen ankles), back pain, heart failure, upset stomach (possibly leading to stomach or duodenal ulcer), potassium loss, dizziness, fatigue, insomnia, weight gain, increased appetite, nausea, stomach gas, abdominal pain, general pain, muscle weakness, loss of muscle mass, slowed healing of wounds, increased sweating, allergic rash, itching, convulsions, excess hair growth, and worsening of a pre-existing psychiatric condition.
✓    Less common: irregular menstruation; slowed growth in children, particularly after lengthy periods of corticosteroid treatment; adrenal or pituitary gland suppression; diabetes; drug sensitivity or allergic reactions; blood clots; moon face; feeling unwell; euphoria; mood swings; personality Changes; and severe depression.
♦    Rare: Rare side effects can appear in any part of the body. Contact your doctor if you experience any side effect not listed above.
Drug Interactions
•    Tell your doctor if you are taking any oral anticoagulant (blood-thinning) drug. If you begin taking a corticosteroid, your anticoagulant dosage may have to be adjusted.
•    Combining a corticosteroid and a diuretic such as hydrochlorothiazide may cause loss of blood potassium. Low blood potassium may increase the side effects of digitalis drugs.
•    Contraceptive drugs, estrogen, erythromycin, azithromycin, clarithromycin, and ketoconazole may increase the risk of corticosteroid side effects.
•    Barbiturates, aminoglutethimide, phenytoin and other hydantoin anticonvulsants, rifampin, ephedrine, colestipol, and cholestyramine may reduce the effectiveness of corticosteroids.
•    Corticosteroids may decrease the effects of aspirin and other salicylates, growth hormones, and isoniazid.
•    Combining a corticosteroid and a theophylline drug may require a dosage adjustment of either or both drugs.
•    Corticosteroids may interfere with laboratory tests. Tell your doctor if you are taking any of these drugs so that tests are properly analyzed.
•    Limit your intake of alcohol while on oral corticosteroids.
Food Interactions
Take corticosteroids with food or a small amount of antacid to avoid stomach upset. If stomach upset continues, notify your doctor. Grapefruit juice doubles the amount of some oral corticosteroids absorbed into the blood.
Usual Dose
Once-daily doses should be taken in the morning. Dosages vary greatly and depend upon the specific disease being treated. Dosages for infants and children should be individualized according to severity of disease and response to treatment.
Betamethasone: starting dosage-0.6-7.2 mg a day. Maintenance 1609age-0.6-7.2 mg a day.
Budesonide: 9 mg a day.
Cortisone: starting dosage-25-300 mg a day. Maintenance dosage-25-300 mg a day.
Dexamethasone: 0.75-9 mg a day. Daily dosage sometimes exceeds 9 mg. A temporary dosage increase may be necessary it you are experiencing emotional stress. In alternate-day therapy, twice the usual daily dose is taken every other day.
Hydrocortisone: 20-240 mg a day.
Methylprednisolone: starting dosage-4-48 mg or more a day. Maintenance dosage varies. A temporary dosage increase may be necessary if you are experiencing emotional stress. in alternate-day therapy, twice the usual daily dose is taken every other day.
Prednisone and Prednisoione: 5-60 mg a day. Daily dosage sometimes exceeds 60 mg. A temporary dosage increase may be necessary if you are experiencing emotional stress. In alternate-day therapy, twice the usual daily dose is taken every other day.
Equivalent doses: Using 5 mg of prednisone as the basis for comparison, equivalent doses of other corticosteroids are 0.6 mg-0.75 mg of betamethasone, 25 mg of cortisone, 0.75 mg of dexamethasone, 20 mg of hydrocortisone, 4 mg of methylprednisolone, and 5 mg of prednisolone.
Overdosage
Symptoms of overdose are anxiety, depression or stimulation, joint or muscle pain, blurred vision, stomach bleeding, increased blood sugar, high blood pressure, and water retention. The victim should be taken to a hospital emergency room immediately. ALWAYS bring the prescription bottle or container.
Special Information
Do not stop taking this medication without your doctor’s knowledge. Suddenly stopping any corticosteroid drug may have severe consequences; the dosage must be gradually reduced by your doctor.
G& your doctor if you develop unusual weight gain, black or tarry stools, swelling of the feet or legs, muscle weakness, vomiting of blood, menstrual irregularity, prolonged sore throat, fever, cold or infection, appetite loss, nausea and vomiting, diarrhea, weight loss, weakness, dizziness, or low blood sugar.
If you take several doses a day and forget a dose, take the dose you forgot as soon as possible. It it is almost time for your next dose, skip the one you forgot and double the next dose. If you take 1 dose a day and forget a dose, skip the dose you forgot and continue with your regular schedule. Do not take a double dose.
If you take a corticosteroid every other day and forget a dose, take it immediately if you remember it in the morning of your regularly scheduled day. If it is much later in the day, skip the dose you forgot and take it the following morning, then go back to your regular schedule. Do not take a double dose.
Special Populations
Pregnancy/Breast-feeding: Studies have shown that long-term corticosteroid therapy at high dosages may cause birth defects, as may chronic corticosteroid use during the first 3 months of pregnancy. When this drug is considered crucial by your doctor, its potential benefits must be carefully weighed against its risks.
Corticosteroids taken by mouth may pass into breast milk. Most nursing mothers who must take a corticosteroid should use infant formula, though low dosages of some of these drugs may be taken for short periods while breast-feeding. Consult your doctor.
Seniors: Seniors are more likely to develop high blood pressure while taking an oral corticosteroid. Older women are more susceptible to osteoporosis (a condition characterized by loss of bone mass due to depletion of minerals, especially calcium) associated with high dosages of oral corticosteriods. Lower dosages are just as effective in seniors and cause fewer side effects.

Prescribed For
Inflammation, itching, eczema, dermatitis, vitiligo (patchy loss of skin color), blistering skin diseases, lupus and other connective tissue diseases, psoriasis, and many other specialized skin problems; may also be used to Weal severe diaper rash.
General Information
Topical corticosteroids do not cure the underlying cause of skin problems, but they can relieve symptoms of rash, itching, or inflammation by interfering with the body mechanisms that produce them. You should never use a topical corticosteroid without your doctor’s knowledge because it could mask a symptom important in diagnosing your condition. Also, improper use of a topical corticosteroid could lead to unwanted and sometimes permanent side effects. In general, ointment forms of topical steroids are more potent and usually more effective than cream or lotion forms. Ointments are also less likely to cause allergic reactions because they contain fewer inactive ingredients.
Generic products in this group can vary in potency and produce different results from their brand-name counterparts, even though they contain the identical quantity of active ingredient. Topical steroids are rated from 1 (most potent) to 7 (least potent). Generally, products within a potency class are interchangeable. Ask your doctor or pharmacist which products are interchangeable. The lowest potency products are available without a prescription. Ointments tend to be more potent than creams and solutions and different product concentrations affect their classification.
Super-potent topical corticosteroids (class 1) should not be used on the face, neck, under the arms, or in the groin area. These products are generally reserved for situations in which less potent products have not worked. They should be used with caution, and should only be applied to the areas that are affected with the rash. Using a product in this category for longer than 2 weeks at a time increases the risk of permanent skin damage.
High-potency topical corticosteroids (classes 2 and 3) are best for the trunk, arms, and legs, but should not be used on the face, neck, under the arms, or in the groin area. Using a product in this category for longer than 2 weeks at a time increases the risk of permanent skin damage.
Intermediate-potency topical corticosteroids (classes 4 and 5) can be used in children for up to 1-2 weeks at a time. This type of medication is best for the trunk and extremities. It is safer for use on thin skin, and less effective on thicker skin.
Low-potency topical corticosteroids (classes 6 and 7) can be used on any part of the body, and can be used in children. They are the best choice for the face, uadera~m area, groin, neck, and i ftl Occluded areas such as skin folds.
Cautions and Warnings
Do not use a topical corticosteroid if you are allergic or sensitive to corticosteroids or to any ingredients of the aerosol, cream, gel, lotion, ointment, or solution. Do not use a topical corticosteroid as the sole treatment for bacterial skin infections such as impetigo, viral skin diseases such as herpes, fungal skin infections such as athlete’s foot, or known tuberculosis of the skin. These drugs should not be used in the ear if the eardrum is perforated. Do not use a topical corticosteroid on ulcerated skin, or to treat acne.
Skin problems can become less responsive with time if a product is applied continuously over a long period of time. This can re-
sult in a flare-up of the problem when the medication is stopped.
Using a less potent product may avoid this problem.
Rectal corticosteroid products should not be used if you have any serious bowel condition, including bowel perforation, obstruction, abscess, and systemic fungal infection.
The rectal foam is not expelled after it has been applied and may result in higher drug blood levels than those associated with rectal enema products. The risk of systemic (whole-body) side effects is greater when more of the drug enters the blood. If there is no improvement after 2 or 3 weeks of using a rectal corticosteroid, contact your doctor.
Using a topical corticosteroid around the eyes for prolonged periods may cause cataracts, glaucoma and/or permanent thinning and fragility of skin around the eyes where the corticosteroid is being applied.
Children may be more susceptible to serious systemic side effects from topical corticosteroids, including growth retardation, Cushing’s syndrome, and suppression of natural corticosteroid production, requiring a tapering of the medication, especially if the medications are applied to large areas over long periods. Super-potent topical corticosteroids are not recommended for children.
Possible Side Effects
♦ Most common: burning; itching; irritation; “steroid” acne; skin thinning, tightening, or discoloration; stretch marks; dry cracked skin; bruising; and secondary i0ection. These effects are more likely when the treated area is covered Stith al) occlusive bandage (one that prevents contact with water and air). Side effects are more likely with extended use of high-potency topical corticosteroid products and when the treated area is covered with a bandage that completely prevents skin contact with water and air.
Possible Side Effects (continued)
V Significant amounts of corticosteroids may be absorbed into the bloodstream if large amounts are used for long periods. This can result in systemic effects and may cause serious problems, particularly in people with liver disease. Systemic side effects include lightheadedness, hives, growth suppression, and adrenal suppression.
Drug Interactions None known.
Usual Dose
Adult
Cream, Ointment, Solution, Foam, and Aerosol: Apply a thin film to the skin 2-3 times a day. High- and super-potent products should be applied no more than twice a day, and should be used for short-term treatment, usually 2-3 weeks at a time. Some may have to be applied only once a day.
Rectal Enema: 100 mg nightly for 21 days.
Rectal Foam: 1 applicator’s worth, 1-2 times a day for 2-3 weeks.
Child: Dosages for children should be limited to the lowest possible potency.
Overdosage
Serious adverse effects are unlikely after accidental ingestion. Excessive use of large amounts of topical corticosteroids may cause overdose symptoms and require gradual discontinuation of the drug. Call your local poison control center or a hospital emergency room for more information. ALWAYS bring the prescription bottle or container.
Special Information
To prevent secondary infection, clean the skin before applying the drug. Apply a very thin film and rub in gently—effectiveness depends m contact area, not the thickness of the layer applied.
Do not wash, rub, or put clothing on the area until the medication has dried.
Topical corticosteroids have an additive effect: with continuous use, 1 or 2 applications a day may be as effective as 3 or more. Once the drug begins to take effect, your doctor may recommend reducing the dose to the minimum level needed to control the
condition.
Flurandrenolide tape comes with specific directions for use-, fol-
low them carefully.
If your doctor instructs you to apply plastic wrap or any other occlusive dressing, follow directions carefully. These dressings can increase the penetration of the drug into your skin by as much as 10 times, which may be a crucial element in the medication’s effectiveness. Occlusive dressings should not be used with any of the super-potent topical products.
If you are using one of these products for diaper rash, do not use tight-fitting diapers or plastic pants, which can cause too much drug to be absorbed into the blood.
Your doctor may prescribe a specific form of the product with good reason. Do not change forms without your doctor’s knowledge: a different form may not be as effective.
If you forget to administer a dose, do so as Soon as you remember. If it is almost time for your next dose, skip the one you forgot and continue with your regular schedule. Do not administer a double dose.
Special Populations
Pregnancy/Breast-feeding: Large amounts of corticosteroids applied to the skin for long periods of time may increase the risk of birth defects. When your doctor considers any of these drugs crucial, its potential benefits must be carefully weighed against its risks. Do not use any over-the-counter hydrocortisone product for more than a few days without your doctor’s knowledge.
Nursing mothers who must use a topical corticosteroid should consider using infant formula. If you apply a corticosteroid to the nipple area, be sure to completely clean the area prior to nursing. Nursing mothers should never use the highest potency corticosteroids (classes 1, 2 or 3) because of the risk of absorbing large amounts of drug into the system that could find its way into breast milk. Nursing mothers should discuss toqkoa1 corticosteroid use with their doctor befQ(e,applying any product.
Seniors: Seniors are more susceptible to high blood pressure and osteoporosis (a condition characterized by loss of bone mass due to depletion of minerals, especially calcium) associated with large dosages. These effects are unlikely with topical corticosteroids unless a high-potency medication is used over a large area for an extended period.

Brand Name
Cosopt
Generic Ingredients  Dorzolamide + Timolol
Type of Drug
Carbonic anhydrase inhibitor and beta blocker combination.
Prescribed For
Open-angle glaucoma and ocular hypertension.
General Information
Cosopt contains 2 glaucoma drugs that work in different ways. It is intended for people whose glaucoma does not respond to either drug used alone. Small amounts of dorzolamide and timololthe active ingredients in Cosopt–enter the bloodstream.
Cautions and Warnings
Do not use Cosopt if you are allergic or sensitive to any of its ingredients or cannot take sulfa drugs or beta blockers. Cosopt should not be used by people with bronchial asthma, severe chronic obstructive pulmonary disease, slow heart rate or heart block, heart failure, or who are in shock.
People with diabetes or an overactive thyroid should use Cosopt with caution since beta blockers can mask the signs of low blood sugar or hyperthyroidism.
Small amounts of both ingredients enter the bloodstream and can produce the same kinds of systemic (whole-body) reactions associated with larger dosages of either a sulfa drug or beta blocker. Stop using the drug at once and call your doctor if a serious reaction develops.
4lt?18b)ockers may have to be discontinued prior to major surgery because they can affect the heart’s ability to respond normally. Some people taking a beta blocker experience severe reductions in blood flow while undergoing general anesthesia.
Dorzolamide should not be used by people with kidney disease and has not been studied in people with liver disease.
People with a history of severe allergic reactions who take a beta blocker may be at increased risk of experiencing a reaction because the drug blocks part of the body’s natural allergic
response.
Timolol can worsen the muscle weakness that accompanies myasthenia gravis.

Allergic and inflammatory eye conditions, and to speed healing after eye surgery or injury.
General Information
Corticosteroid eye products are prescribed for general relief of inflammation due to allergy and other causes. They are also used after eye surgery or serious eye injury to aid the healing process by reducing the natural inflammatory process. Very severe eye conditions that do not respond to these products may require treatment with corticosteroid drugs taken by mouth. Fluorometholone, medrysone, and prednisolone (up to 0.125%) are preferred for long-term treatment because they are least likely to raise the fluid pressure inside the eye. corticosteroid eye products have not been widely studied in children, though fluorometholone has been proven safe for use in children age 2 and over.
Cautions and Warnings
Do not use a corticosteroid eye product if you are allergic or sensitive to corticosteroids. These products should be used with caution if you have a fungal, herpes, tuberculosis, or viral infection of the eye, or have cataracts, glaucoma, or diabetes. Do not use any of these products without your doctor’s knowledge.
Long-term use of these products can lead to eye damage, including glaucoma, infection, and nerve damage.
Do not use any of these products in children without consultng a doctor.
Possible Side Effects
V Rare: watery eyes; glaucoma; optic nerve damage; gradual blurring, reduction, or loss of vision; eye pain or infections; drooping eyelid; eye burning, stinging, or redness; nausea; and vomiting. Contact your doctor if you experience any side effect not listed above.
Drug Interactions
•    Corticosteroids applied to the eye may interfere with the effect of antiglaucoma drugs.
•    The risk of raising fluid pressure inside the eye is increased when corticosteroid eye products are taken with anticholinergic drugs, especially atropine, over a long period of time.
Food Interactions  None known.
Usual Dose
Eyedrops: 1-2 drops several times a day.
Eye Ointment: Place a thin strip of ointment into the affected eye several times a day.
Overdosage
Swallowing a container of corticosteroid eyedrops or ointment usually does not produce serious effects. Call your local poison center or a hospital emergency room for more information. ALWAYS bring the prescription container.
Special Information
If you forget to administer a dose, do so as soon as you remember. If it is almost time for your next dose, skip the one you forgot and continue with your regular schedule.
To prevent infection, keep the eyedropper from touching your fingers, eyelids, or any surface. Wait at least 5 minutes before using any other eyedrops.
If the brand you are taking contains benzalkonium chloride, wait at least 15 minutes before inserting contact lenses. In some cases, you may be instructed not to wear contact lenses for the duration of treatment.
Special Populations
Pregnancy/Breast-feeding: Using large amounts of corticosteroid eyedrops during pregnancy may affect the adrenal gland of the fetus. When your doctor considers one of these products crucial, its potential benefits must be carefully weighed against its risks.
Oral corticosteroids pass into breast milk, but it is not known if this is also true of corticosteroid eyedrops. Nursing mothers who must use one of these medications should use infant formula.
Seniors: Seniors may use these products without special precaution.

Chronic asthma and bronchial disease.
General Information
Corticosteroid inhalers relieve the symptoms associated with asthma and bronchial disease by reducing inflammation of bronchial mucous membranes, making it easier to breathe. Corticosteroid inhalers produce the same treatment effect as oral corticosteroids, with some important differences. Because inhalers deliver the drug directly to the lungs, smaller dosages can be used. They also have fewer side effects because little of the drug reaches the bloodstream. Corticosteroid inhalers can prevent asthma attacks if used regularly but do not relieve them once they start.
Cautions and Warnings
Do not use a corticosteroid inhaler if you are allergic or sensitive to any of its ingredients.
Corticosteroid inhalers should not be used as the primary treat- MV)~ of severe asthma. They are recommended only for people who take prednisone or another oral corticosteroid, or for people who do not respond to other asthma drugs. These drugs cannot relieve asthma attacks once they start.
In people with asthma, death from adrenal gland failure has occurred during and after switching from an oral corticosteroid to an inhaler. Adrenal function is impaired for several months after the
switch.
Those who use any corticosteroid product, including inhalation, are more likely to have reduced immune system function. This reduces the body’s ability to fight infection from any source, including chicken pox, shingles, and measles. Adults who have not had these viral infections should take care to avoid becoming infected while using any corticosteroid product. Do not receive a live virus vaccine while taking corticosteroids of any kind, as they interfere with the body’s reaction to the vaccine.
Combining an oral corticosteroid with a corticosteroid inhaler may cause pituitary gland suppression.
During a period of severe stress, you may have to switch to an oral corticosteroid if the inhaler does not control your asthma. During periods of stress or a severe asthmatic attack, people who have stopped using an inhaler should ask their doctors about taking an oral corticosteroid.
corticosteroid inhalers may be associated with immediate or delayed drug reactions, including breathing difficulties, rash, and bronchospasm.
Use corticosteroids with caution if you have respiratory tuberculosis, herpes of the eye, a bacterial, fungal, or parasitic infection, or any other untreated systemic infection.
The combination products Advair and Symbicort both contain beta-2 agonists. In some asthma patients, beta-2 agonists may increase the risk of asthma-related death. See Formoterol, page 509, and Salmeterol, page 1013, for more information on these drugs.
Possible Side Effects
V Most common: dry mouth, hoarseness, rash, bronchospasm, respiratory infections, fungal infection of the mouth, runny nose, headache, upset stomach, and palpitations.
V Rare: depression, cough, wheezing, infection, and facial swelling. Cough and wheezing are probably caused by an ingredient in the inhaler other than the corticosteroid itself. GW20 your doctor if you experience any side effect not listed above.
Drug Interactions
• Ketoconazole may increase blood levels of budesonide and fluticasone.
•    Using an inhaled corticosteroid and an oral corticosteroid together may increase the effect of both drugs. Use with
caution.
•    See Formoterol, page 509, for further drug interactions for the
combination product Symbicort.
•    See Salmeterol, page 1013, for further drug interactions for
the combination product Advair. Food Interactions

Overdosage
Serious adverse effects are unlikely. Excessive use of large amounts of an inhaled corticosteroid may cause overdose symptoms and require gradually stopping the drug. Call your local poison control center or a hospital emergency room for more information.
Special Information      People using both a corticosteroid inhaler and a bronchodilator, such as albuterol, should use the bronchodilator first, wait a few minutes, and then use the corticosteroid inhaler. This allows more corticosteroid to be absorbed.
These drugs are for preventive therapy only and will not affect an asthma attack. Inhaled corticosteroids must be taken regularly, as directed. Wait at least 1 minute between inhalations.
To properly take this medication, thoroughly shake the inhaler if it is one that must be shaken. Take a drink of water to moisten your throat. Place the inhaler 2 finger-widths away from your mouth and tilt your head back slightly. While activating the inhaler, take a slow, deep breath for 3-5 seconds. then hold your breath for about 10 seconds, and finally breathe out slowly. Allow at least 1 minute between puffs. Rinse your mouth after each use to reduce dry mouth and hoarseness.
If you forget to administer a dose, do so as soon as you remember. If it is almost time for your next dose, skip the dose you forgot and continue with your regular schedule. Do not take a double dose. Tell your doctor or pharmacist if you forget to take more than 1 dose.
Special Populations
Pregnancy/Breast-feeding: corticosteroids may cause birth defects or interfere with fetal development. When any of these drugs is considered crucial by your doctor, its potential benefits Must be carefully weighed against its risks.
It is not known if inhaled corticosteroids pass into breast milk, though oral corticosteroids do. Nursing mothers who must take an inhaled corticosteroid should use infant formula.
StniOrs: Seniors may use corticosteroid inhalers without special restriction. Tell your doctor if you have bone or bowel disease, colitis, diabetes, glaucoma, fungal or herpes infections, high blood pressure, high blood cholesterol, an underactive thyroid, or heart, kidney, or liver disease.

Prescribed For
Rhinitis (nasal inflammation) associated with seasonal or chronic allergy and other causes; also used to prevent recurrence of nasal polyps.
General Information
Nasal corticosteroids are used to treat severe symptoms of seasonal allergy that have not mSpDrided to other drugs such as deQQQgtS%TAS. ‘They work by reducing inflammation of the mucous membranes that line the nasal passages, making it easier to breathe. These drugs may take several days to produce an effect. Some nasal corticosteroids are approved for both allergic and non-allergic rhinitis.
Cautions and Warnings    __  allergic or sensitive Do not use a nasal corticosteroid if you ate alle
to corticosteroids. Rarely, serious and life-threatening drug-sensitivity reactions have occurred.
very rarely, deaths caused by failure of the adrenal gland have occurred in people taking adrenal corticosteroid tablets or syrup who were switched to a nasal corticosteroid. This is a rare complication and usually results from stopping the liquid or tablets suddenly instead of gradually.
Combining prednisone or another oral corticosteroid with a nasal corticosteroid may cause pituitary gland suppression, although nasal corticosteroids alone rarely cause this problem.
Use nasal corticosteroids with caution if you have tuberculosis, chicken pox, measles, shingles, or any serious fungal, bacterial, or viral infection.
Do not receive a live virus vaccine while taking corticosteroids of any kind, as they interfere with the body’s reaction to the vaccine.
Rarely, nasal Candida infections develop in people using a nasal corticosteroid. These infections may require treatment with an antifungal drug, as well as the discontinuance of the nasal corticosteroid.
During a period of severe stress, you may have to switch to an oral corticosteroid drug if the nasal form does not control your symptoms.
Children using nasal corticosteriods may experience reduction in growth velocity.
Possible Side Effects
✓    Most common: mild irritation of the nose, nasal passages,
and throat; burning; stinging; dryness; and headache.
♦    Less common: lightheadedness, nausea, nosebleed or bloody mucous, unusual nasal congestion, bronchial asthma, sneezing attacks, runny nose, sore throat, and loss of the sense of taste.
✓    Rare: ulcers 0 Vie nasal passages, watery eyes, vomiting. hypersensitivity reactions (symptoms include itching, rash, swelling, bronchospasms, and breathing difficulties), nasal infection, wheezing, perforation of the wall between the nostrils, and increased eye pressure. Contact your doctor if you experience any side effect not listed above.
Drug Interactions
•    Do not use fluticasone propionate with ritonavir.
•    Ephedrine, phenobarbital, and rifampin may decrease the effect of nasal corticosteroids.
•    Use caution when combining ketoconazole with any nasal corticosteroid.

Overdosage
Serious adverse effects are unlikely after accidental ingestion. Rarely, excessive use of large amounts of nasal corticosteroids may cause overdose symptoms such as irregular menses, acne, facial puffiness, and weight gain. These symptoms require gradual, not immediate, discontinuation of the drug. Call your local poison control center or a hospital emergency room for more information. ALWAYS bring the presciption container.
Special Information
It may be necessary to clear your nasal passages with a nasal decongestant before using a nasal corticosteroid to allow it to reach the mucous membranes.
Some of these drugs take 10-14 days to start working. Beclomethasone, budesonide, and triamcinolone work faster. in 3-7 days: ciclesonide starts working within 1 or 2 days and shows additional benefits after several weeks of use; in some cases, triamcinolone and budesonide provide relief in 12 hours. FWT isolide may take up to 2 weeks. Do not use -any of these drugs continuously for more tha”‘3 weeks unless you have experienced a def- fttlbenefit.
If you are using more than one spray at a time, wait at least 1 minute between sprays.
Nasal corticosteroids may cause irritation and drying of mucous membranes in the nose. Call your doctor if this effect persists or if symptoms get worse.
Call your doctor if you are exposed to measles or chicken pox while using an of these medicines.
People using a nasal corticosteroid to prevent the return of nasal polyps after surgery may experience nosebleeds because the drug can slow healing of the wound.
If you forget to administer a dose, do so as soon as you remember. If it is almost time for your next dose, skip the dose you forgot and continue with your regular schedule. Do not take a double dose.
Special Populations
Pregnancy/Breast-feeding: Taking large amounts of corticosteroids during pregnancy may slow fetal growth. While the small amount of drug absorbed into the blood after nasal application is unlikely to have any effect, consult your doctor before taking any corticosteroid if you are or might be pregnant.
Dexamethasone passes into breast milk. Nursing mothers who must use this drug should use infant formula. It is not known if other nasal corticosteroids pass into breast milk, though oral corticosteroids do. Nursing mothers should consider using infant formula.
Seniors: Seniors may use nasal corticosteroids without special restriction. Tell your doctor if you have bone or bowel disease, colitis, diabetes, glaucoma, fungal or herpes infections, high blood pressure, high blood cholesterol, an underactive thyroid, or heart, kidney, or liver disease.

Celecoxib (sel-eh-KOX-ib)
Brand Name
Celebrex
Type of Drug
Cyclooxygenase-2 (COX-2) inhibitor nonsteroidal anti-inflammatory
drug (NSAID).
Prescribed For
Osteoarthritis, rheumatoid arthritis, juvenile rheumatoid arthritis, acute pain, some colon polyps (FAR), menstrual pain, and arthritis of the spine (ankylosing spondylitis).
General Information
Traditional NSAIDs work primarily by blocking the effects of COX-2, a body enzyme that plays an important role in regulating pain and inflammation. But these NSAIDs also have an unwanted effect: They interfere with cyclooxygenase-1 (COX-1), a related enzyme that helps to maintain the stomach’s protective lining. NSAIDs that block the effects of this enzyme may produce side effects such as stomach irritation, gas, and stomach ulcers.
COX-2 inhibitors such as celecoxib are a class of NSAIDs that work about as well as the older NSAIDs. In fact, both 200 mg a day and 400 mg a day of celecoxib work as well as naproxen 500 mg twice a day. They interfere primarily with COX-2, leaving the stomach-protecting COX-1 relatively unaffected. This means that COX-2 inhibitor NSAIDs can relieve pain and inflammation just like traditional NSAIDs but are less likely to cause gastrointestinal (GI) side effects. Another advantage of celecoxib is that it does not cause thinning of the blood or affect blood platelets as can happen with older NSAIDs. Celecoxib is broken down in the liver.
Black patients absorb about 40% more celecoxib than Caucasians; its importance is unclear. Celecoxib is the first drug proven effective in reducing the number of intestinal polyps in people with the rare genetic disorder FAR
Cautions and Warnings
Do not take celecoxib if you are allergic or sensitive to any of its ingredients or to sulfa drugs. NSAIDs should not be taken by people with asthma or by those who have had a” allergic reaction to aspirin or another NSA13.1hey can develop a group of sympWMS V1Jnny nose with or without nasal polyps and a severe bronchial spasm) known as the aspirin triad.
COX-2 inhibitors, including celecoxib, have been associated with high blood pressure, kidney damage, heart attacks, and stroke. It should not be used to treat pain associated with heart bypass surgery. Two other COX-2 inhibitors were taken off the market because of safety concerns. Rofecoxib was removed because safety issues were noted after people had taken it for 18 months or more. Valdecoxib was taken off the market because of the lack of safety data, severe skin rashes, and concerns raised in people taking the drug after having had heart surgery.
NSAIDs can cause GI bleeding and ulcers and stomach perforation. This can occur at any time, with or without warning, in people who take NSAIDs regularly. Celecoxib should be used with caution by people who have had stomach ulcers or GI bleeding. Minor upper GI problems, such as upset stomach, are common and may occur at any time during NSAID therapy. People who develop bleeding or ulcers and continue NSAID treatment should be aware of the risk of developing more serious side effects. Risk of GI bleeding and ulcers is increased with longer duration of therapy as well as treatment with oral corticosteroids and anticoagulants, smoking, alcoholism, older age, and general poor health.
Children taking celecoxib may be more likely to vomit blood, suffer acute kidney failure, or develop rashes.
Celecoxib has not been studied in people with severe kidney disease. They should not use this drug unless their doctors closely monitor their kidney function.
Celecoxib can cause liver irritation and should be used with caution by people with hepatitis or cirrhosis. People with moderate liver disease can have twice as much celecoxib in their blood and require a reduced dosage. The effect of celecoxib in people with severe liver failure is not known.
Possible Side Effects
Side effects are similar to those of traditional NSAIDs. Stomach and intestinal side effects are about half as common.
♦    Most common: headache.
✓    Common: diarrhea, upset stomach, sinus irritation, and respiratory infection.
♦    Less common: abdominal pain, gas, nausea, back pain, swelling in the legs m arms, accidental injuries, sleeplessness, dizziness, sore throat, runny nose, and rash.
✓    Rare: Rare side effects can occur in almost any part of the body. Contact your doctor if you experience any side effect not listed above.
Drug Interactions
•    Alcohol may increase the risk of serious GI-related side ef-
fects. Avoid alcohol.
•    Combining celecoxib with an aluminum and magnesium antacid slightly reduces the amount of drug absorbed. Separate doses of these antacids and celecoxib by 1-2 hours.
•    Fluconazole and lithium may raise celecoxib blood levels and increase the risk of side effects.
•    While celecoxib may be combined with low dosages of as-
pirin, taking these drugs together can increase the risk of
stomach or intestinal ulcers or other complications. The ulcer
risk associated with this combination is less than that posed
by single-drug therapy with a traditional NSAID.
•    Celecoxib can reduce the blood-pressure-lowering effect of angiotensin-converting enzyme (ACE) inhibitors and diuretic drugs. This combination can also increase the risk of kidney damage after chronic celecoxib use.
•    Celecoxib may affect lithium blood levels.
•    NSAIDS can reduce the effect of furosemide and thiazidetype diuretics.
•    Celecoxib should be used cautiously with warfarin. Concurrent use of these drugs may cause an increased risk of bleeding complications.
Food Interactions
Celecoxib can be taken without regard to Food or meals. For optimal effectiveness, avoid taking this drug with high-fat meals.
Usual Dose
Adult (age 18 and over): arthritis-100-200 mg once or twice a day. FAP-400 mg twice a day.
Child (age 2 and over): juvenile rheumatoid arthritis-22-55 lbs: 50 mg twice a day; over 55 lbs: 100 mg twice a day.
Child (under age 2): not recommended.
Overdosage
Overdosage symptoms include Mnargy, drowsiness, nausea, vomitiR(;, 16M Stomach pain. Stomach or intestinal bleeding or severe allergic reactions can occur. High blood pressure, kidney failure, breathing difficulties, and coma are rare.
The victim should be taken to a hospital emergency room. ALWAYS bring the prescription bottle or container.
Special Information
Call your doctor if you develop rash, itching, unexplained weight gain, nausea, fatigue, jaundice (yellowing of the skin or whites of the eyes), flu-like symptoms, lethargy, swelling, black stools, severe stomach pain, persistent headache, or any bothersome or persistent side effect.
If you forget a dose and remember within 1 or 2 hours of your scheduled time, take it right away. If you do not remember until later, skip the forgotten dose and continue with your regular schedule.
Special Populations
Pregnancy/Breast-feeding: celecoxib has caused birth defects in animal studies. Any NSAID may affect fetal heart development during the second half of pregnancy. Pregnant women should not take celecoxib without their doctor’s approval. When this drug is considered crucial by your doctor, its potential benefits must be carefully weighed against its risks.
NSAIDs may pass into breast milk. There is a possibility that a nursing mother taking celecoxib could affect her baby’s heart or cardiovascular system. Nursing mothers who must take this drug should use infant formula.
Seniors: Generally, seniors can take this drug without special precaution. Those who weigh less than 110 lbs. should begin with the lowest possible dosage.

Prescribed For
Prevention and treatment of osteoporosis (a condition characterized by loss of bone mass due to calcium depletion) in postmenopausal women and in older men; Paget’s disease of bone; and high blood calcium associated with high dosages of corticosteroid treatments and cancer.
General Information
Bisphosphonates have been used for many years to treat a variety of conditions associated with low bone mass caused by calcium depletion. They work on cells called osteoclasts that normally break down bone tissue, making bones stronger by preventing loss of bone mass. In osteoporosis, bones become weak and brittle, increasing the risk of spine, hip, and other bone fractures that are a major cause of death and disability in older women. Etidronate has been used occasionally in children, but these drugs generally are not considered safe for use in children.
Cautions and Warnings
Do not use any bisphosphonate if you are allergic or sensitive to any of its ingredients.
Do not use bisphosphonates if you have severe kidney disease or active stomach or intestinal disease such as difficulty swallowing, ulcers, or stomach irritation. Notify your doctor if you experience any gastrointestinal problems while taking bisphosphonates.
Osteonecrosis of the jaw (ONJ), a condition in which bones of the jaw lose their blood supply and eventually collapse, has been reported in people treated with bisphosphonates. Most cases of ONJ have been in cancer patients having dental procedures such as tooth extractions. People at risk may be those with cancer and those taking corticosteroids or those with poor oral hygiene.
Do not use ibandronate, alendronate, or risedronate it you cannot stand or sit upright for 30 minutes (see “Special Information”).
Bisphosphonates can cause low blood calcium and should not be used by people whose blood calcium is already low.
Bisphosphonates can cause severe and sometimes incapaciating bone,    muscle pain.
Possible Side Effects
Side effects are generally mild and similar to those reported by people taking an inactive placebo (sugar pill).

Special Information
Food interferes with the effectiveness of these drugs. Carefully follow the directions in “Food Interactions” above.
Do not suck on any of these tablets or allow them to dissolve in your mouth because they can cause mouth sores.
To reduce the risk of stomach and throat irritation, do not lie down for at least 30 minutes after taking alendronate or risedronate. Do not lie down for 60 minutes after taking ibandronate.
Separate doses of calcium, iron, and vitamin D supplements from those of a bisphosphonate by at least 2 hours. If you forget a dose, take it as soon as you remember. If it is almost time for your next dose, skip the dose you forgot and continue with your regular schedule. If you forget a morning dose and take it later in the day, you must still follow the instructions in “Food Interactions” about avoiding food.
Special Populations
Pregnancy/Breast-feeding: Bisphosphonates cause abnormal bone development in animal fetuses and are toxic to pregnant animals. When any of these drugs is considered crucial by your doctor, its potential benefits must be carefully weighed against its risks.
It is not known if bisphosphonates pass into breast milk. Since these drugs affect bone formation, nursing mothers who must take a bisphosphonate should use infant formula.
Seniors: Seniors may use these drugs without special restriction.

cytotoxic drugs A term applied to drugs that can kill cancer cells. In practice, many factors influence their therapeutic value. They are rarely selective, and therapeutic doses usually have a toxic effect on sonic normal cells. They may attack cancer cells at different stages of development, as actively dividing cells are more susceptible than resting cells. They may not reach the cancer cells in adequate concentration, or resistance to the drug may develop. The dose may also depend to some extent on the patient’s tolerance of the drug, and combined treatment with two or more drugs may have the advantages of increased potency with reduced toxicity. All cytotoxic drugs, with the exception of bleomycin and vincristine, bring about a depression of the bone marrow, which may be severe, and some degree of hair loss, which is usually reversible. Severe nausea and vomiting are also common, and early use of powerful antiemetics is essential. Many cytotoxic agents are tissue irritants, and with i.v. treatment great care must be taken to avoid extravasation, as severe local tissue damage can occur. See alkylating agents and antimetabolites. See page 122.
