How should I use azithromycin ophthalmic?
Azithromycin ophthalmic is usually applied twice daily for 2 days, and then once daily for 5 more days. Use exactly as prescribed by your doctor. Do not use in larger or smaller amounts or for longer than recommended. Follow the directions on your prescription label.
Wash your hands before using the eye drops.
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 with the tip down. Look up and away from the dropper and squeeze out a drop.
Close your eyes for 2 or 3 minutes with your head tipped down, without blinking or squinting. Gently press your finger to the inside corner of the eye for about 1 minute, to keep the liquid from draining into your tear duct.
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 medication for the full prescribed length of time. Your symptoms may improve before the infection is completely cleared.
Store an unopened bottle of azithromycin ophthalmic in the refrigerator. Do not freeze.
After opening the bottle, you may keep the medication at room temperature for up to 14 days. Keep the bottle tightly closed when not in use. Protect from moisture and heat.
What happens if I miss a dose?
Use the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not use extra medicine to make up the missed dose.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.
What should I avoid while taking azithromycin ophthalmic?
Do not use this medication while wearing contact lenses. Azithromycin ophthalmic may contain a preservative that can discolor soft contact lenses. Wait at least 15 minutes after using azithromycin ophthalmic 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 (eye redness, irritation, or drainage).
