Drugs & Medications

Zymaxid ophthalmic



This medication is a quinolone antibiotic used for eye infections (such as conjunctivitis).

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 Zymaxid ophthalmic

For best results, use exactly as directed for the full time prescribed. Stopping this medication too soon may result in a return of the infection.

To apply eye drops, wash hands first. To avoid contamination, do not let the dropper tip touch any surface.

Tilt your head back, gaze upward and pull down the lower eyelid to make a pouch. Place the dropper directly over eye and instill the prescribed number of drops. Look downward and gently close your eye for 1 to 2 minutes. Place one finger at the corner of the eye near the nose and apply gentle pressure. This will prevent the medication from draining away from the eye. Try not to blink and do not rub the eye. Do not rinse the dropper.

If you are using other kinds of eye drops, wait at least five minutes before applying the other medications.

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 using them.

Tell your doctor if your condition does not improve in 7 days.
