Zymaxid Ophthalmic Solution is an antibiotic eye drop medication used to treat bacterial infections of the eye, specifically bacterial conjunctivitis. It contains the active ingredient gatifloxacin, which is a quinolone antibiotic that works by killing the bacteria causing the infection.

Use and Dosage

Zymaxid is administered as a sterile ophthalmic solution for topical administration into the eye and is prescribed for patients ages one and older.

To use Zymaxid Ophthalmic Solution, first, wash your hands, then remove the cap from the bottle that contains the eye drops. Tilt your head back and pull down your lower eyelid to create a small pocket. Hold the bottle upside down over your eye and gently squeeze one drop of the solution into the pocket formed by the lower eyelid. Close your eyes for a few seconds to allow the drops to be absorbed. If you have been instructed to use the eye drops in both eyes, repeat the process for the other eye. Be sure to replace the cap on the bottle after each use.

Follow your doctor's instructions on how often to use the eye drops and how many days to continue treatment. Do not stop using the medication early as it can result in a return of the infection.
