What is AzaSite?
AzaSite is an eye drop containing azithromycin, a macrolide antibiotic that fights bacteria.
AzaSite is used to treat eye infections caused by bacteria.
AzaSite may also be used for purposes not listed in this medication guide.
Use AzaSite for the full prescribed length of time. Your symptoms may improve before the infection is completely cleared.
Stop using AzaSite and get emergency medical help if you have any signs of a rare but serious reaction: fever, sore throat, swelling in your face or tongue, burning in your eyes, skin pain followed by a red or purple skin rash that spreads (especially in the face or upper body) and causes blistering and peeling.
Do not use this medication while wearing contact lenses. AzaSite may contain a preservative that can discolor soft contact lenses. Wait at least 15 minutes after using AzaSite before putting your contact lenses in.
You should not wear contact lenses while you still have active symptoms of the eye infection you are treating.
Serious side effects of AzaSite may include eye drainage or crusting, severe eye irritation, feeling like there is something in your eye, watery eyes, increased light sensitivity, eye redness or swelling, any signs of new infection.

It is not known whether azithromycin ophthalmic passes into breast milk or if it could harm a nursing baby. Do not use this medication without telling your doctor if you are breast-feeding a baby.

How should I use AzaSite eye drops?
AzaSite eye drops are usually applied twice daily for 2 days, and then once daily for 5 more days. Follow your doctor's dosing instructions very carefully.
Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.

Use only the number of drops your doctor has prescribed.
Use only the number of drops your doctor has prescribed. If you use more than one drop, wait about 5 minutes between drops.
Wait at least 10 minutes before using any other eye drops your doctor has prescribed.
