What is Zirgan or generic Ganciclovir?

Zirgan ophthalmic gel or generic Ganciclovir is an antiviral medication that is prescribed for the treatment of eye infections/ulcers resulting from the herpes simplex virus. This type of infection, which is dubbed herpetic keratitis or acute herpetic keratitis, may range from mild to severe enough that it affects the ocular nerves and possibly leads to blindness.

The active ingredient in Zirgan is Ganciclovir, which is thought to inhibit DNA replication of the herpes simplex virus, thereby helping to halt herpetic keratitis. People dealing with eye infections stemming from the herpes simplex virus may be prescribed this medication.

Drugs similar to Zirgan include:

Conditions treated by Zirgan or generic Ganciclovir

Zirgan or Ganciclovir ophthalmic gel is used to treat herpes keratitis, which is a viral infection of the eye that results from the herpes simplex virus.

The herpes simplex virus is usually categorized as one of two main types.

  • Type I is the most common type. It usually infects the face and is the cause of common cold sores.
  • Type II is the sexually transmitted form of herpes, which leads to infection in the genitals.

Each of these types of the herpes simplex virus can lead to eye infections, but Type I is most likely. Eye infections may occur if, for example, you or someone else touches an active lesion (such as a cold sore) and then touches your eye.

Zirgan ophthalmic gel or Ganciclovir gel does not cure herpes, and it will not treat herpes symptoms in other parts of the body.

While Zirgan or Ganciclovir are generally used in the treatment of herpes keratitis, these medications may also be prescribed for other purposes.

What to know before using Zirgan or generic Ganciclovir

Prior to using Zirgan, keep the following in mind:

  • Tell your doctor about any other medical conditions or medications that you take. Also let them know if you are pregnant, breastfeeding, or planning to become pregnant.

  • Carefully follow your doctor's directions for using Zirgan gel. Do not use more or less than directed, and follow the directions for use on the prescription label.

  • See your doctor regularly while using Zirgan to monitor your progress and examine your eyes.

  • Always wash your hands prior to using Zirgan gel or Ganciclovir ophthalmic gel. Do not touch the dropper to any surface, including your eyes or skin, as this can provoke additional infection and possibly lead to serious eye damage.

  • Do not use contact lenses or other eye medications while taking Zirgan (unless your doctor has also prescribed the other eye medication). Ask your doctor about the appropriate time to resume wearing contacts.

  • Because Zirgan may cause blurred vision, be cautious about driving, operating machinery, or handling sharp objects while taking this medication.

  • If you miss a dose and it is near the time of your next dose, simply continue with your regular dosing schedule. If you miss a dose and it is not near the time of your next dose, take the dose as soon as you remember and then continue with your regular dosing schedule. Do not double up on doses. If you believe you have overdosed, seek emergency medical attention.

Zirgan or generic Ganciclovir FAQs

What is the proper Ganciclovir or Zirgan dosage?

The proper Zirgan dosage depends on the patient and the condition, so it's important to follow your doctor's directions. In general, the recommended dosage for Zirgan is one drop administered in the affected eye five times per day until the ulcer heals, and then one drop three times per day for an additional seven days.

What is the difference between Zirgan and generic Ganciclovir?

Both Zirgan and generic Ganciclovir contain the same active ingredient (Ganciclovir), which helps treat acute herpetic keratitis.

If you're unsure whether the brand or generic version is right for you, consult your doctor.
