Gentamicin ointment (generic Gentak)
Member Price: $45
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 Gentak Ointment
To apply eye ointment, wash your hands first. To avoid contamination, be careful not to touch the tip of the tube or let it touch your eye, eyelid, or any other surface. Apply to 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.
To apply eye ointments, tilt your head back, look up, and gently pull down the lower eyelid to make a pouch. Place a half-inch (1.3 centimeters) strip of ointment into the pouch as directed by your doctor. Gently close the eye and roll the eyeball in all directions to spread the medication. Try not to blink and do not rub the eye. Repeat these steps for your other eye if so directed. Wipe the tip of the ointment tube with a clean tissue to remove extra medication before recapping it. Wait several minutes for your vision to clear before driving or operating machinery.
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 frequently as the infection improves. Do not increase your dose or use it more often than directed. 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.
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 using it for the full time prescribed. Stopping the medication too soon may allow the bacteria to continue to grow, which may result in a return of the infection.
Tell your doctor if your condition persists or worsens.
