Why is this medication prescribed?

Zirgan (ganciclovir ophthalmic gel) is an antiviral medication used to treat certain viral eye infections, specifically those caused by herpes simplex virus (HSV) or cytomegalovirus (CMV). These infections can affect the cornea of the eye and may lead to conditions such as keratitis.

How should this medicine be used?

Here’s a general guideline on how Zirgan is typically used:

  • Dosage: The usual dose is a small amount of gel (approximately 1/2 inch or 1.27 cm) applied to the affected eye(s) five times per day. The treatment duration and frequency of use may vary based on the severity of the infection and the healthcare provider’s recommendations.
  • Administration:
    • Wash your hands thoroughly before applying the medication.
    • Tilt your head backward or lie down and look up.
    • Gently pull down your lower eyelid to create a small pocket between your eyelid and eyeball.
    • Place the prescribed amount of Zirgan gel into the pocket using a clean fingertip or a sterile applicator provided with the medication.
  • Avoid Contamination: Be careful not to touch the tip of the applicator or your fingertip with your eye, eyelashes, or any other surface, as this can introduce bacteria and compromise the sterility of the medication.
  • Contact Lenses: If you wear contact lenses, remove them before applying the gel and wait at least 15 minutes before reinserting them.
  • Continue Treatment: Continue using Zirgan for the full course of treatment, even if symptoms improve before completion.
  • Adherence to Prescription: It’s essential to follow your healthcare provider’s instructions regarding the dose and duration of treatment. Do not alter the dosage or stop using the medication without consulting your doctor.
  • Side Effects: Be aware of any side effects or adverse reactions. If you experience persistent or worsening symptoms or notice any unusual side effects, contact your healthcare provider promptly.

Always use Zirgan exactly as prescribed by your healthcare provider. If you have any questions or concerns about the medication or its use, consult your healthcare professional for clarification. Additionally, inform your healthcare provider about any other medications you are taking, including over-the-counter drugs and supplements, to avoid potential interactions.
