This medication is used to treat bacterial eye infections (such as conjunctivitis). It belongs to a class of drugs known as sulfa antibiotics. Sulfacetamide works by stopping the growth of 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 Cetamide Opht
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 or any other surface. Apply to the eyes only. Do not swallow or inject.
Do not wear contact lenses while you are using this medicine. Sterilize contact lenses according to 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. 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. Use as directed by your doctor. 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. Follow your doctor\'s directions exactly. Your doctor may direct you to use sulfacetamide drops during the day and the 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, usually 7 to 10 days. 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.
Eye stinging/burning/redness and temporary blurred vision may occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.
