Pronounced

Common brand names:

Diogent, Garamycin, Gentak

Uses

This medication is used to treat bacterial infections (such as blepharitis, conjunctivitis) of the eye and the skin around the eyes (such as eyelids). It is also used to prevent infection after eye injury or surgery. It belongs to a class of drugs known as aminoglycoside antibiotics. Gentamicin works by killing the bacteria.

This medication treats only bacterial eye infections. It will not work for other types of eye infections. Unnecessary use or misuse of any antibiotic can lead to its decreased effectiveness.

How to Use This Medication

Use this medication in the affected eye(s) as directed by your doctor, usually every 4 hours.

To apply eye drops, wash your hands first. To avoid contamination, do not touch the dropper tip or let it touch your eye or any other surface. Use in the eyes only. Do not swallow or inject.

Do not wear contact lenses while you are using this medication. Sterilize contact lenses according to the manufacturer's directions, and check with your doctor before you begin using them again.

Tilt your head back, look upward, and pull down the lower eyelid to make a pouch. Hold the dropper directly over your eye and place one drop into the pouch as directed by your doctor. Look downward, gently close your eyes, and place one finger at the corner of your eye (near the nose). Apply gentle pressure for 1 to 2 minutes before opening your eyes. This will prevent the medication from draining out. Try not to blink or rub your eye. Repeat these steps for your other eye if so directed or if your dose is for more than 1 drop. Do not rinse the dropper. Replace the dropper cap after each use.

The dosage is based on your medical condition and response to treatment. Your doctor may direct you to use this medication more often at first, then use it less often as the infection improves. Follow your doctor's directions carefully. Your doctor may prescribe gentamicin drops for use during the day and gentamicin ointment at bedtime.

If you are using another kind of eye medication (such as drops or ointments), wait at least 5 minutes before applying other medications. Use eye drops before eye ointments to allow the drops to enter the eye.

Wait several minutes for your vision to clear before driving or operating machinery.

Use this medication regularly in order to get the most benefit from it. To help you remember, use it at the same times each day. Continue to use this medication for the full time prescribed, even if symptoms disappear after a few days. Stopping the medication too early may result in a return of the infection.

Tell your doctor if your condition lasts or gets worse.
