What is ganciclovir?

Ganciclovir is an antiviral medicine.

Ganciclovir ophthalmic (for the eyes) is used to treat eye ulcers caused by herpes infection in adults and children at least 2 years old.

Ganciclovir ophthalmic is not a cure for herpes and will not treat symptoms of herpes in any other part of your body.

Ganciclovir ophthalmic may also be used for purposes not listed in this medication guide.

Warnings

Use only as directed. Tell your doctor if you use other medicines or have other medical conditions or allergies.

Before taking this medicine

Tell your doctor if you are pregnant or breastfeeding.

ganciclovir ophthalmic should not be given to a child younger than 2 years old.

How should I use ganciclovir?

Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.

Ganciclovir ophthalmic is usually applied about every 3 hours while you are awake (up to 5 times per day). Once the eye ulcer heals, the gel is usually applied 3 times per day for 7 days. Follow your doctor's dosing instructions very carefully.

Wash your hands before using eye medication.

To apply the eye gel: Pull down your lower eyelid to create a small pocket and squeeze a drop into this pocket. Close your eyes for 1 or 2 minutes.

Use only the prescribed number of drops.

Do not touch the dropper tip or place it directly on your eye. A contaminated dropper can infect your eye and lead to serious vision problems.

Ask your doctor before using contact lenses. Wearing them may increase your risk of repeated herpes infections or eye ulcers.

Do not wear contact lenses while you have an active eye ulcer or infection.

Ganciclovir does not cure herpes and your infection may come back. You may need frequent vision exams.

Store at room temperature away from moisture and heat. Do not freeze.

What happens if I miss a dose?

Use the medicine as soon as you can, but skip the missed dose if it is almost time for your next dose. Do not use two doses at one time.

What happens if I overdose?

Seek emergency medical attention or call the Poison Help line at 1-800-222-1222 if anyone has accidentally swallowed the medicine.

What should I avoid while taking ganciclovir?

May cause blurred vision. Avoid driving or hazardous activity until you know how ganciclovir ophthalmic will affect you.

Avoid touching your eyes. Wash your hands frequently to prevent the spread of infection.

Do not use other eye medications unless your doctor tells you to.
