How should I use natamycin ophthalmic (Natacyn)?

Use natamycin ophthalmic eyedrops exactly as directed by your doctor. If you do not understand these directions, ask your pharmacist, nurse, or doctor to explain them to you.

Wash your hands before using your eyedrops.

To apply the eyedrops:

• Shake the drops gently to be sure the medicine is well mixed. Tilt your head back slightly and pull down on your lower eyelid. Position the dropper above your eye. Look up and away from the dropper. Squeeze out a drop and close your eye. Apply gentle pressure to the inside corner of your eye (near your nose) for about 1 minute to prevent the liquid from draining down your tear duct. If you are using more than one drop in the same eye or drops in both eyes, repeat the process with about 5 minutes between drops.

Do not touch the dropper to any surface, including your eyes or hands. The dropper is sterile. If it becomes contaminated, it could cause an infection in your eye.

Do not use any eyedrop that is discolored or has particles in it.

Store natamycin ophthalmic at room temperature away from moisture and heat. Keep the bottle properly capped.
