Azithromycin
Why this is used
Azithromycin is used to treat certain infections caused by bacteria, such as bronchitis; pneumonia; sexually transmitted diseases (STD); and infections of the ears, lungs, skin, and throat. Azithromycin is in a class of medications called macrolide antibiotics. It works by stopping the growth of bacteria. Antibiotics will not work for colds, flu, or other viral infections.
How to take it
Azithromycin comes as a tablet and oral suspension (liquid) to take by mouth. It is usually taken with or without food once a day for 1-5 days. To help you remember to take azithromycin, take it around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take azithromycin exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor. Shake the liquid well before each use to mix the medication evenly. Use only the syringe provided to measure the correct amount of medication. Rinse the syringe with water after taking the full dose of medication. The tablets should be taken with a full glass of water. Take azithromycin until you finish the prescription, even if you feel better. Stopping azithromycin too soon may cause bacteria to become resistant to antibiotics.
