Ganciclovir
Zirgan
Zirgan (ganciclovir) is an antiviral medication used to treat eye ulcers caused by the virus, also known as herpes simplex virus, in adults & children aged 2 years and older. While not a cure for cytomegalovirus or herpes, Zirgan targets the affected eye to manage symptoms by preventing the virus from replicating. This medication comes in a gel form and is administered as a drop directly to the affected eye under a specific dosage regimen to ensure effectiveness. Patients are advised not to wear any contact lenses during treatment and to maintain strict hygiene to prevent contamination & the spread of infection. If you plan to buy Zirgan online, trust reliable Canadian pharmacies for quality medications.
Product Overview
Zirgan (ganciclovir) is a specialized antiviral treatment to manage eye ulcers specifically caused by the herpes simplex virus. Approved for use in adults and children over the age of 2, Zirgan is effective in treating these specific ocular conditions by inhibiting the DNA replication of the virus, thus controlling the spread and severity of the infection. The medication is packaged in a 5g bottle of 0.15% ganciclovir gel. To treat acute herpetic keratitisa, a common form of eye ulcer caused by herpes, Zirgan is applied one drop at a time in the affected eye five times daily until the patient sees improvement.
Once improvement is noted, the application is reduced to three times daily for an additional seven days to ensure full efficacy. Applying Zirgan requires careful attention to hygiene; hands must be washed thoroughly before use, and the dropper must not touch any surfaces, including the eye itself, to avoid contamination. Patients are instructed not to wear contact lenses during the treatment period and to avoid any activities that could introduce bacteria to the eye area.
The treatment comes with specific precautions, such as not using Zirgan if there is a known allergy to ganciclovir or acyclovir. Side effects can include blurred vision and red, sore eyes, but more serious symptoms like painful eye irritation or redness should be reported to a healthcare provider immediately. Zirgan eye drops should be stored at room temperature and kept out of reach of children. It is crucial not to use the medication past its expiration date and to discard it properly to ensure safety. Patients should always follow their healthcare provider’s instructions and discuss any potential interactions with other medications they are taking.

- Zirgan is prescribed to treat eye ulcers caused by the herpes simplex virus. This medication is suitable for use in adults and children who are at least 2 years old.
[Important Warning: Zirgan is not a cure for cytomegalovirus (CMV) or herpes infections. It is an ophthalmic gel administered as an eye drop and does not treat other body parts where these viruses might exist.]

- Zirgan is available as an ophthalmic gel. Each bottle contains 5 grams of the gel, which has a concentration of 0.15%.
What Are the Recommended Dosage of Zirgan?
The correct dosage of Zirgan eye drops may vary depending on the individual’s needs. Always follow the dosage prescribed by your healthcare provider. Do not alter your dosage without consulting your doctor. The dosage depends on the medicine’s strength, the number of doses you take each day, the time between doses, and the duration for which the medicine is prescribed. Here are the average dosage recommendations of Zirgan for different patients:

How Do You Administer Zirgan?
Proper administration steps are important for the effective use of the medication. The following section discusses the detailed steps on how to use Zirgan eye drops.
- Follow your doctor’s instructions when using Zirgan on your affected eye.
- Typically, you will apply it 5 times a day every 3 hours while you are awake until your eye heals. After that, continue applying it 3 times a day for another 7 days.
- Use this medication consistently at the same times each day to maximize its effectiveness. Continue using it for the entire duration prescribed, even if your symptoms improve early. Stopping too soon may cause the infection to return.
- Inform your doctor if your condition persists or worsens, such as if you experience increased eye pain, swelling, or itching.
Application Steps:
- Clean Hands: Always wash your hands thoroughly before applying the eye medication to avoid contamination.
- Avoid Contact: Do not touch the dropper tip to your eye or any other surface to keep it germ-free.
- Contact Lens Caution: Do not wear contact lenses during an eye infection or while using this medication. Follow your lens manufacturer’s sterilization instructions and consult your doctor before using them again.
- Application Technique:
-
-
- Tilt your head back and look up.
- Pull down the lower eyelid to create a small pocket.
- Hold the dropper above the eye and squeeze out a drop into the pocket.
- After applying, look down and gently close your eyes.
- Press gently at the corner of your eye near your nose for 1 to 2 minutes. This helps keep the medicine in the eye.
- Avoid blinking or rubbing your eyes.
- If you need to treat both eyes, repeat these steps for the other eye.
-
- Dropper Care: Do not rinse the dropper. Close the dropper cap tightly after each use.
- If Using Other Eye Medications: If you are prescribed other eye drops or ointments, wait at least 5 minutes between each type of medication. Always apply eye drops before ointments to ensure the drops can penetrate the eye properly.
- Post-Application: Allow your vision to clear before you drive or operate machinery.
[Note: Your doctor will decide the right amount for you based on your condition, following guidelines and studies on the drug. They’ll adjust it as needed over time.]

Important Safety Information for Using Zirgan
What Are the Side Effects of Zirgan?
Common Side Effects of Zirgan: Zirgan might cause some temporary side effects, which typically last a few days to weeks. If these side effects persist, become bothersome, or intense, it’s essential to consult your doctor or pharmacist. Common side effects may include:
- Blurred Vision: You may notice temporary blurred vision after applying Zirgan eye gel. This happens due to the medication’s antiviral properties that affect the eye. However, it is a common side effect that usually resolves on its own. Moreover, it is advisable to avoid activities that require clear vision.
- Eye Irritation: Ganciclovir ophthalmic gel may cause mild irritation or a burning feeling in the eye. If this irritation persists for a long time or intensifies, consult a medical professional. They will determine whether or not it is a sign of a serious reaction.
- Redness, Watering, and Sensitivity to Light: These symptoms result from the medication’s reaction, which can lead to discomfort and increased sensitivity. Wear sunglasses and avoid bright lights to alleviate the risk of such symptoms until your eyes adjust to the surroundings.
- Sore Eyes: The ophthalmic gel may lead to soreness in the eyes. This generally happens due to irritation from Zirgan eye drops. Using lubricating eye drops & reducing screen time can help manage this discomfort. If the soreness continues, consult your a medical expert.
Serious Side Effects of Zirgan: While rare, this medication can cause serious side effects. The following list does not include all possible severe side effects. If you experience serious side effects, contact your doctor immediately. In case these side effects seem life-threatening or if you think you’re having a medical emergency, call 911 or your local emergency number without delay. Serious side effects may include:
- Conjunctival Hyperemia: In severe cases, ganciclovir ophthalmic gel can cause redness in the whites of your eyes or inner eyelids. This results from the medication’s reaction as your eyes adjust to the treatment. If left untreated, this side effect can cause adverse complications.
- Corneal Irritation: Zirgan gel may irritate your cornea, leading to discomfort or a burning sensation. This irritation might occur as the eyes react to the medication’s antiviral properties. If not treated on time, it can cause severe reactions. Therefore, if you notice any painful irritation in your cornea (the clear front part of the eye), report it to your doctor immediately.
- Severe Allergic Reactions: In rare cases, this medication can cause severe allergic reactions, including swelling, difficulty breathing, dizziness, itching, and hives. If you suspect any signs or symptoms of an allergic reaction, get medical attention right away to prevent potential complications.
[Note: Remember, this list may not cover all possible side effects. Always consult with your healthcare giver for medical advice about side effects.]
Are There Any Warnings for Zirgan?
Like all medications, Zirgan also has some warnings that can lead to various complications. If you plan to buy Zirgan online to manage eye ulcers, be aware of its warnings to ensure timely prevention:
- Do not use this medication if you are allergic to ganciclovir or acyclovir (Zovirax), as this could lead to severe reactions.
- Avoid wearing contact lenses while using Zirgan, especially if you have an active eye ulcer or infection, to prevent further irritation or damage to your eyes.
- Do not share your ophthalmic gel with others. It has been prescribed specifically for your current eye condition. Doing so may spread the infection, causing irritation in the eyes.
- After applying this medication, you may experience temporary blurred vision. Therefore, it is advisable to avoid driving or using machinery that requires attention until your vision clears.
What Are the Zirgan Precautions?
Zirgan may cause several serious reactions if not used properly. To minimize these risks, it is important to understand its preventive measures. Here are some precautions to keep in mind while using this medication:
- Before using Zirgan, inform your doctor if you have low platelet levels (which can cause easy bruising or bleeding) or any infection in body parts other than your eyes.
- Do not reuse the gel for another infection without consulting your doctor.
- Regular eye exams and possibly other medical tests may be required while using Zirgan. Make sure to keep all your medical and lab appointments.
- If you notice any signs or symptoms of an allergic reaction, inform your doctor immediately to avoid potential risks. The product may contain certain inactive components that can cause severe hypersensitivity reactions.
- The effects of Zirgan on an unborn baby are unknown. If you are pregnant or planning to become pregnant, discuss the risks with your doctor.
- Zirgan, the brand name for ganciclovir ophthalmic gel, may affect fertility in men by decreasing sperm count. Discuss with your doctor if you have concerns about fertility, either as a prospective mother or father.
- It is also not known if ganciclovir passes into breast milk. Do not breastfeed while using this medication without your doctor’s advice.
- Zirgan should not be used in children under 2 years of age.
- If you are using other eye medications along with Zirgan, keep at least a 5-minute interval between them. This allows each medication to be fully absorbed in the eyes.
- This medication is not a cure for viruses like cytomegalovirus or herpes. It only treats eye symptoms caused by these infections and does not address symptoms in other body parts.
What Are the Contraindications of Zirgan?
Do not use this medication if you fall under any of the following categories:
- Hypersensitivity Reactions: Patients with a known allergic reaction to ganciclovir or any of the ingredients present in gel should avoid using this medication. Doing so may cause severe hypersensitivity reactions.
- Pregnancy: Ganciclovir may be contraindicated during pregnancy unless its potential benefits justify the potential risk to the unborn baby, as ganciclovir has been associated with teratogenic & embryotoxic effects in animal studies.
- Severe Bone Marrow Suppression: Ganciclovir and Cytomegalovirus infection may harm the bone marrow. This can lead to a decline in white blood cells, making patients prone to bacterial or fungal infections. These infections can be life-threatening for patients with weakened immune systems.
- Non-Herpetic Conditions: Zirgan is primarily indicated for treating herpes simplex virus keratitis. It should not be used for other conditions unless prescribed by a medical professional.
What If You Missed a Dose of Zirgan?

[Note: If you have missed a dose of your medication and are unsure about when to take the next one, immediately consult your doctor or pharmacist.]
What Happens If You Take Too Much of Zirgan?
- Swallowing Hazard: Zirgan can be harmful if swallowed.
- Emergency Situations: If the person overdosing shows severe symptoms like fainting or difficulty breathing, call 911 immediately.

Frequently Asked Questions
Does Zirgan sting?
Yes, using Zirgan (ganciclovir) can sometimes cause eye discomfort. Some common side effects include a stinging or burning sensation, redness, watering, or a gritty feeling as if something is in your eye. If these symptoms persist or become bothersome, it’s important to contact your doctor or eye care professional. They can help determine whether the discomfort is a normal side effect or if you need to adjust your treatment.
What is the shelf life of Zirgan?
Zirgan has a shelf life of 18 months, which means it remains effective and safe to use for up to a year and a half after being manufactured as long as it is stored properly. The long shelf life, combined with its proven effectiveness, makes Zirgan a reliable option for managing eye infections caused by the herpes virus. If you have any concerns about your medication’s storage or shelf life, consult your pharmacist or healthcare provider for guidance.
Is zirgan a steroid?
No, Zirgan is not a steroid. It is an antiviral medication used to treat eye infections primarily caused by the herpes simplex virus. It works by preventing the virus from spreading in the eye. This process controls the infection and promotes healing. It’s specifically designed to address viral eye conditions and not related to steroid treatment.
Is there a generic for Zirgan?
Currently, no generic version of Zirgan is available. However, there is another antiviral eye medication called trifluridine (Viroptic), also used to treat herpes infections of the eye. Trifluridine is available in a generic form.
How quickly does Zirgan (ganciclovir) work?
Zirgan (ganciclovir) typically starts to work within a week for most people with herpes infections of the eye. Patients are generally advised to use the medication for approximately 7 days until the ulcers on the eye heal. It’s important to attend follow-up appointments with your healthcare provider to ensure the infection is healing correctly. Even after the ulcers heal, you should continue using Zirgan for an additional week to ensure the treatment is completely effective and to prevent the infection from returning.
Is trifluridine the same as Zirgan?
Zirgan (ganciclovir) and trifluridine (Viroptic) are both antiviral medications used to treat eye infections, but they are not the same. Zirgan is known for its ability to selectively target the replication of herpes simplex virus (HSV) DNA, making it less harmful to healthy eye cells. In contrast, trifluridine has been noted for its potential toxicity to the cells of the eye and can affect both infected and healthy corneal cells. This distinction makes Zirgan a preferred choice for some patients due to its targeted action and reduced risk of damaging uninfected eye cells.
Can you use Zirgan for pink eye?
Yes, Zirgan (ganciclovir) can be used to treat pink eye (conjunctivitis) when it’s caused by the herpes simplex virus (HSV). While pink eye can be triggered by various factors, including bacteria, allergies, and different viruses, HSV-specific conjunctivitis requires targeted antiviral treatment. Zirgan is one of the antiviral medications that is effective against this type of infection. However, always consult a healthcare professional for a proper diagnosis and treatment plan tailored to the specific type of conjunctivitis.
