Ganciclovir Ophthalmic
Ganciclovir ophthalmic is used to treat herpetic keratitis (dendritic ulcers; eye ulcers caused by a herpes simplex virus infection). Ganciclovir is in a class of medications called antivirals. It works by stopping the spread of the herpes virus in the eye.
🔔 How should this medicine be used?
Ganciclovir ophthalmic comes as a gel to apply to the eyes. It is usually applied as one drop to the affected eye(s) five times a day (about every 3 hours while awake) until the eye(s) heal. Then apply one drop 3 times a day into the affected eye(s) for another 7 days. Use ganciclovir ophthalmic at around the same times every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Use ganciclovir ophthalmic exactly as directed. Do not use more or less of it or use it more often than prescribed by your doctor.
You should expect your symptoms to improve during your treatment. Call your doctor if your symptoms get worse, do not go away, or if you develop other problems with your eyes during your treatment.
To apply the eye gel, follow these instructions:
- Wash your hands thoroughly with soap and water.
- Avoid touching the tip of the tube against your eye or anything else. The gel must be kept clean.
- Tilt your head back slightly and pull down your lower eyelid to create a small pocket.
- Holding the tube above the eye with the tip down without touching it.
- Place a drop of the gel into the pocket made by the lower lid and the eye by squeezing the bottom of the tube. Look up and away from the tube as you squeeze out a drop of gel.
- Close your eye after the drop goes into your eye Gently press your finger on the inside corner of the eye, near your nose, for 1 minute to keep the gel from going into your tear duct.
- Wipe off any excess gel from your eyelids and lashes with a clean tissue. Wash your hands again.
Ask your pharmacist or doctor for a copy of the manufacturer’s information for the patient.
