Ganciclovir
What is Zirgan used for?
Ganciclovir is used to treat herpes infection of the eye. Although ganciclovir stops the growth of the virus, it is not a cure for the herpes infection. Herpes virus continues to live in the body even between outbreaks of infection. However, treating an outbreak may help the sores in the eye to heal faster and lower the risk of complications (such as decreased vision, blindness). Ganciclovir is an anti-viral drug. This medication treats only herpes eye infections. It will not work for other types of eye infections, such as those caused by bacteria. Unnecessary use or misuse of any anti-infective drug can lead to its decreased effectiveness.

Zirgan Frequently Asked Questions
Apply this medication to the affected eye as directed by your doctor, usually 5 times a day (about every 3 hours while awake) until the eye has healed, and then 3 times a day for 7 more days.
To apply eye medication, wash your hands first. To avoid contamination, do not touch the dropper tip or let it touch your eye or any other surface.
Do not wear contact lenses while you have an eye infection or while using this medication. Sterilize contact lenses according to the manufacturer's directions, and check with your doctor before you begin using them again.
Tilt your head back, look upward, and pull down the lower eyelid to make a pouch. Hold the dropper directly over your eye and place one drop into the pouch. Look downward, gently close your eyes, and place one finger at the corner of your eye (near the nose). Apply gentle pressure for 1 to 2 minutes before opening your eyes. This will prevent the medication from draining out. Try not to blink or rub your eye. Repeat these steps for your other eye if so directed.
Do not rinse the dropper. Replace the dropper cap after each use.
If you are using another kind of eye medication (such as drops or ointments), wait at least 5 minutes between applying each medication. Use eye drops before eye ointments to allow the drops to enter the eye.
Wait several minutes for your vision to clear before driving or operating machinery.
Use this medication regularly to get the most benefit from it. To help you remember, use it at the same times each day. Continue to use this medication for the full time prescribed, even if symptoms disappear after a few days. Stopping the medication too early may result in a return of the infection.
Tell your doctor if your condition lasts or if it gets worse (for example, you develop eye pain/itching/swelling).
