How should I use Zymaxid?

Use Zymaxid exactly as prescribed by your doctor. Do not use in larger or smaller amounts or for longer than recommended. Follow the directions on your prescription label.

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 eye drops.

To apply the Zymaxid 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 as you squeeze out a drop, then close your eye.

  • Use only the number of drops your doctor has prescribed.

  • Gently press your finger to the inside corner of the eye (near your nose) for about 1 minute to keep the liquid from draining into your tear duct. If you use more than one drop in the same eye, wait about 5 minutes before putting in the next drop.

  • Also wait at least 10 minutes before using any other eye drops that your doctor has prescribed.

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.

Do not use the eye drops if the liquid has changed colors or has particles in it. Call your doctor for a new prescription.

Store Zymaxid at room temperature away from moisture and heat. Do not freeze. Keep the bottle tightly closed when not in use.

What happens if I miss a dose?

Use the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not use extra medicine to make up the missed dose.

What happens if I overdose?

An overdose of Zymaxid is not expected to be dangerous. Seek emergency medical attention or call the Poison Help line at 1-800-222-1222 if anyone has accidentally swallowed the medication.

What should I avoid?

You should not wear contact lenses while you still have active symptoms of the eye infection you are treating.

Do not use other eye medications during treatment with Zymaxid unless your doctor tells you to.
