WHY is this medicine prescribed?
Erythromycin is an antibiotic used to treat certain infections caused by bacteria, such as bronchitis; diphtheria; Legionnaires' disease; pertussis (whooping cough); pneumonia; rheumatic fever; venereal disease (VD); and ear, intestine, lung, urinary tract, and skin infections. It is also used before some surgery or dental work to prevent infection. Antibiotics will not work for colds, flu, or other viral infections.
This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.
HOW should this medicine be used?
Erythromycin comes as a capsule, tablet, long-acting capsule, long-acting tablet, chewable tablet, liquid, and pediatric drops to take by mouth. It usually is taken every 6 hours (four times a day) or every 8 hours (three times a day) for 7 to 21 days. Some infections may require a longer time. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take erythromycin exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Shake the liquid and pediatric drops well before each use to mix the medication evenly. Use the bottle dropper to measure the dose of pediatric drops.
The chewable tablets should be crushed or chewed thoroughly before they are swallowed. The other capsules and tablets should be swallowed whole and taken with a full glass of water.
Continue to take erythromycin even if you feel well. Do not stop taking erythromycin without talking to your doctor.
