How should I use gentamicin ophthalmic (Gentak)?

Use gentamicin ophthalmic eyedrops or ointment 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 the eyedrops or ointment.

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.

To apply the ointment:

• Hold the tube in your hand for a few minutes to warm it up so that the ointment comes out easily. Tilt your head back slightly and pull down gently on your lower eyelid. Apply a thin film of the ointment into your lower eyelid. Close your eye and roll your eyeball around in all directions for 1 to 2 minutes. If you are applying another eye medication, allow at least 10 minutes before the next application.

Do not touch the dropper or tube opening to any surface, including your eyes or hands. The dropper or tube opening 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 gentamicin ophthalmic at room temperature away from moisture and heat. Keep the bottle or tube properly capped.
