Ganciclovir belongs to the class of medications called antivirals. Ganciclovir ophthalmic gel is used to treat eye infections affecting the cornea, that are caused by herpes viruses.
This medication may be available under multiple brand names and/or in several different forms. Any specific brand name of this medication may not be available in all of the forms or approved for all of the conditions discussed here. As well, some forms of this medication may not be used for all of the conditions discussed here.
Your doctor may have suggested this medication for conditions other than those listed in these drug information articles. If you have not discussed this with your doctor or are not sure why you are taking this medication, speak to your doctor. Do not stop taking this medication without consulting your doctor.
Do not give this medication to anyone else, even if they have the same symptoms as you do. It can be harmful for people to take this medication if their doctor has not prescribed it.
What form(s) does this medication come in?
Each gram of sterile, preserved, opalescent, colourless, topical ophthalmic gel contains 1.5 mg of ganciclovir. Nonmedicinal ingredients: benzalkonium chloride (as preservative), carbomer, sodium hydroxide, sorbitol, and water.
How should I use this medication?
The recommended adult dose of ganciclovir eye gel is one drop of gel in the infected eye(s) 5 times daily (approximately every 3 hours while awake) until the eye is healed. After healing, use one drop of gel into the infected eye(s) 3 times a day for 7 days.
To use the eye drops:
- Wash your hands before using the eye drops.
- Remove the cap and place it in a clean location. To avoid possible contamination, keep the tip of the container away from contact with any surface.
- Tilt your head back and look towards the ceiling.
- With your index finger, gently pull the lower eyelid down and away from the eye to form a pouch.
- Apply one drop into the pouch by following the instructions on the eye drop container. Do not allow the tip of the container to touch the eye or area around the eye.
- Gently apply pressure to the inner corner of the eye (at the bridge of the nose) for about 30 seconds (this is called nasolacrimal occlusion). This prevents the medication from dripping down through the tear duct and entering the bloodstream, which could cause you to experience some side effects.
- Repeat with the other eye, if prescribed by your physician.
- Wash your hands again to remove any medication.
Do not allow the bottle's dropper tip to touch the eye or other surrounding structures. This can contaminate the tip with common bacteria known to cause eye infections. Serious damage to the eye may result if you use eye drop solutions that have become contaminated.
