What is Zymaxid?
Zymaxid (gatifloxacin) is a fluoroquinolone antibiotic that fights bacteria.
Zymaxid eye drops are used to treat eye infections caused by bacteria.
Zymaxid may also be used for purposes not listed in this medication guide.
Do not allow the Zymaxid dropper tip to touch any surface, including the eyes or hands. If the dropper becomes contaminated it could cause an infection in your eye, which can lead to vision loss or serious damage to the eye.
Call your doctor at once if you have a serious side effect such as severe swelling, burning, redness, or discomfort, eye pain or vision changes, signs of new eye infection (drainage, crusting, or oozing), or the first sign of any skin rash, no matter how mild.
Avoid wearing contact lenses while using Zymaxid eye drops while you still have active symptoms of the eye infection you are treating. Do not use other eye drops or medications during treatment unless otherwise directed by your doctor.
Follow all directions on your Zymaxid label and package. Tell each of your healthcare providers about all your medical conditions, allergies, and all medicines you use.

How should I use Zymaxid?
Use Zymaxid exactly as prescribed by your doctor. Follow all directions on your prescription label. Do not use this medicine in larger or smaller amounts or for longer than recommended.
You may need to use the eye drops every 2 hours for the first couple of days, and then every 4 hours for the rest of your treatment. Follow your doctor's instructions.
Wash your hands before using the Zymaxid eye drops.
To apply the eye drops:
Tilt your head back slightly and pull down your lower eyelid to create a small pocket. Hold the dropper above the eye with the tip down. Look up and away from the dropper and squeeze out a drop.
Close your eyes for 2 or 3 minutes with your head tipped down, without blinking or squinting. Gently press your finger to the inside corner of the eye for about 1 minute, to keep the liquid from draining into your tear duct.
Use only the number of drops your doctor has prescribed.
Do not touch the tip of the eye dropper or place it directly on your eye. A contaminated dropper can infect your eye, which could lead to serious vision problems.
Do not use Zymaxid eye drops if the liquid has changed colors or has particles in it. Call your pharmacist for new medicine.
Store at room temperature away from moisture and heat. Do not freeze. Keep the bottle tightly closed when not in use.
