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

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.

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.

Generic Name
Carvedilol (car-VAY-dih-lol)
Brand Names
Coreg    Coreg CR
Type of Drug  Alpha-beta-adrenergic blocker.
Prescribed For
Heart failure, high blood pressure, angina pain, and cardiomyopathy.
General Information
Carvedilol was the first beta blocker approved for heart failure. It is also the only beta blocker approved for severe heart failure.
Carvedilol blocks both the alpha- and beta-adrenergic portions of the central nervous system. This dual action reduces the amount of blood pumped with each heartbeat and also decreases the risk of tachycardia (very rapid heartbeat). Carvedilol’s beta-blocking effects begin within an hour of taking the first dose; maximum blood-pressure-lowering occurs after 1 or 2 weeks. The drug also causes blood vessels to dilate (widen), allowing the heart to pump blood more efficiently.
Cautions and Warnings
Do not take carvedilol if you are allergic or sensitive to any of its ingredients, or if you have AV block, sick sinus syndrome or severe bradycardia (slow heart rate) without the use of a pacemaker.
Carvedilol should not be taken 13y patients with bronchial disease, qQQkVaS thronic bronchitis, emphysema, or asthma.
Carvedilol therapy should not be stopped suddenly due to the risk of worsening the heart condition.
In studies, carvedilol caused mild and reversible liver injury in about 1 of every 100 people who took it. Those with severe liver disease should not take this medication. Call your doctor at once if you develop signs of liver damage (symptoms include severe itching, dark-colored urine, flu-like symptoms, appetite loss, and yellowing of the skin or whites of the eyes).
Check with your doctor about continuing carvedilol if you are to receive general anesthesia; heart function that is depressed by anesthetics can worsen if carvedilol is used at the same time.
Make sure your doctor knows if you have diabetes. Carvedilol can mask signs of low blood sugar and may increase the effects of insulin or oral antidiabetes drugs, making it more difficult to recover from the effects of low blood sugar.
Carvedilol can mask symptoms of an overactive thyroid gland. Abruptly stopping carvedilol can trigger an attack of hyperthyroidism.
Possible Side Effects
Most side effects are considered mild or moderate.
✓    Most common: dizziness, sleepiness or sleeplessness, diarrhea, abdominal pain, slow heartbeat, dizziness when rising from a sitting or lying position, swelling of the hands or feet, sore throat, breathing difficulties, tiredness, back pain, urinary infection, and viral infection.
✓    Less common: extra heartbeats; palpitations; blood-pressure changes; fainting; reduced blood supply to the arms and legs (symptoms include aches, cramps, pain, or tiredness on walking, or pain in the foot, thigh, hip, or buttocks); tingling in the hands or feet; reduced sensation; depression; nervousness; constipation; gas; liver irritation; cough; impotence and reduced sex drive in men; itching; rash; visual difficulties; ringing or buzzing in the ears; high blood cholesterol, sugar, or uric acid; anemia; weakness; hot flushes; leg cramps; dry mouth; not feeling well; sweating; and muscle ache.
✓    Rare: Rare side effects can affect the heart, mental status, the respiratory tract, the urinary tract, and the kidney. It can also cause hair loss, weight gain, high blood-triglyceride levels, low blood-platelet counts, and sugar in the urine. Contact your doctor if you experience any side effect not listed above.
Drug Interactions
•    Carvedilol increases the effects of insulin and oral antidiabetes drugs. People taking this combination must monitor their blood sugar levels regularly. Call your doctor if there is any change from your normal pattern.
•    Carvedilol increases the effects of verapamil, diltiazem, and similar calcium-channel blocking drugs.
•    Monoamine oxidase inhibitor antidepressants may increase the effects of carvedilol.
•    Carvedilol increases the blood-pressure-lowering effect of clonidine. People taking this combination may need less clonidine to control their pressure.
•    Carvedilol increases the amount of digoxin in the blood by about 15%. Your digoxin dosage may have to be adjusted.
•    Cimetidine increases the amount of carvedilol absorbed into the blood by about 30%, but the importance of this interaction is not clear.
•    Rifampin reduces the amount of carvedilol in the blood by about 70%. Dosage adjustment is necessary.
•    Do not consume alcohol (including medicines that contain alcohol) within 2 hours of taking carvedilol.
Food Interactions
Take carvedilol with food to reduce the risk of dizziness or fainting.
Usual Dose
Heart Failure
Adult: 3.125 mg twice a day for 2 weeks. Dose may be doubled every 2 weeks to the highest level tolerated. Maximum daily dosage is 25 mg twice a day in people weighing less than 187 lbs., and 50 mg twice a day in people who weigh more.
High Blood Pressure and Cardlomyopathy
Adult: 6.25 mg twice a day to start, increased to 25 mg twice a day if needed.
Senior: Seniors may require smaller doses than younger adults. Child (under age 18): not recommended.
Overdosage
~3%rdose may lead to very low blood pressure (symptoms include dizziness and fainting), slow heartbeat and other cardiac symptoms, including shock and heart attack, breathing difficulties, bronchial spasm, vomiting, periods of unconsciousness, and seizures. Overdose victims must be taken to a hospital emergency room. ALWAYS bring the prescription bottle or container.
Special Information
Carvedilol should be taken continuously. Do not stop taking it without your doctor’s knowledge, because abrupt withdrawal may cause chest pain, breathing difficulties, increased sweating, and unusually fast or irregular heartbeat. The dose should be gradually reduced over a period of about 2 weeks.
People taking carvedilol may become dizzy or faint when rising quickly from a sitting or lying position. If this happens to you, sit or lie down until you feel better. Carvedilol can also cause drowsiness, lightheadedness, or blurred vision. Be careful when driving or doing any task that requires concentration.
Contact lens wearers are more likely to experience dry eyes with carvedilol.
Swallow extended-release tablets whole; do not crush or break them.
It is best to take carvedilol at the same time each day. If you forget a dose, take it as soon as you remember. If it is within 4 hours of 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: Animal studies indicate that carvedilol passes into the fetal bloodstream and may interfere with pregnancy. When this drug is considered crucial by your doctor, its potential benefits must be carefully weighed against its risks.
It is not known if carvedilol passes into human breast milk, though it passes into rat breast milk. Beta-blocking drugs like carvedilol may affect babies’ hearts. Nursing mothers who must take this drug should use infant formula.
Seniors: Seniors are more likely to develop dizziness and may require reduced dosage.
