Azithromycin is a macrolide antibiotic that fights bacteria.

Azithromycin ophthalmic (for the eyes) is used to treat eye infections caused by bacteria.

Azithromycin ophthalmic may also be used for purposes not listed in this medication guide.

Stop using this medicine and get emergency medical help if you have signs of a severe skin reaction: fever, sore throat, burning eyes, skin pain, red or purple skin rash with blistering and peeling.

Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.

Azithromycin ophthalmic is usually applied twice daily for 2 days, and then once daily for 5 more days. Follow your doctor's dosing instructions very carefully.

Do not use while wearing soft contact lenses. A preservative in this medicine could permanently stain the lenses. Use the medicine at least 15 minutes before inserting your contact lenses.

Wash your hands before using eye medication.

Turn the bottle upside down and shake it once just before each use.

To apply the eye drops: Tilt your head back slightly and pull down your lower eyelid to create a small pocket. Hold the dropper above the eye and squeeze a drop into this pocket. Close your eyes for 1 or 2 minutes.

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.

Do not touch the tip of the eye dropper or place it directly on your eye. A contaminated dropper can infect your eye, which could lead to serious vision problems.

Do not use the eye drops if the liquid has changed colors or has particles in it. Call your pharmacist for new medicine.

Use this medicine for the full prescribed length of time, even if your symptoms quickly improve. Skipping doses can increase your risk of infection that is resistant to medication.
