Ganciclovir

Ganciclovir is an antiviral medicine used to treat cytomegalovirus (CMV) retinitis in people with a weak immune system and to prevent CMV disease in at-risk transplant recipients. This guide covers ganciclovir uses, how it works, dosage, side effects, precautions, drug interactions, use in pregnancy and breastfeeding, brand names and its approximate price in India.

At a Glance

What is Ganciclovir?

Ganciclovir is an antiviral medicine for cytomegalovirus (CMV). CMV is a common virus. It can cause serious illness in people whose immune system is weak. Ganciclovir is used in adults for treatment of CMV retinitis and prevention of CMV disease in at-risk transplant recipients. Ganciclovir does not cure CMV retinitis. The eye problem can still worsen during or after treatment, so regular eye checks are important.

How Ganciclovir Works

Ganciclovir is an antiviral medicine that inhibits CMV DNA polymerase, an enzyme the virus needs to copy its genetic material. The medicine is activated inside cells and interferes with viral DNA replication. Because it can also affect healthy cells, particularly blood-forming cells, blood counts need to be monitored during treatment.

When Ganciclovir Is Used

CMV retinitis

Ganciclovir is used to treat CMV retinitis in immunocompromised adults, including people with AIDS.

Preventing CMV disease

It is also used to prevent CMV disease in adult transplant recipients who are at risk.

Your doctor decides if ganciclovir is appropriate for your condition.

Ganciclovir Dosage and How It Is Given

The dosage is individualized according to the condition being treated, body weight and kidney function. The prescribing information used for ganciclovir includes different treatment phases and requires dose adjustment when kidney function is reduced.

Ganciclovir should be given only as prescribed by a healthcare professional. Do not calculate, start, stop or change the dose yourself.

Kidney function

Ganciclovir is cleared mainly through the kidneys. Reduced kidney function can cause the medicine to remain in the body longer, so the dose or dosing interval may need to be adjusted. Kidney function should be checked before and during treatment.

Children

Safety and effectiveness have not been established in pediatric patients. Use in children should be determined by an appropriate healthcare professional.

How it is given

Ganciclovir injection is administered intravenously by a healthcare professional. It should be given as a controlled infusion rather than as a rapid injection. It should not be administered into a muscle or under the skin.

Side Effects of Ganciclovir

Blood-count changes

Ganciclovir can lower white blood cells, red blood cells and platelets. Tell your doctor promptly about fever, signs of infection, unusual bruising or bleeding.

Kidney problems

Kidney function can worsen during treatment, particularly in people who already have kidney problems or who receive other medicines that can affect the kidneys. Kidney function should be monitored during treatment.

Nerve and brain effects

Seizures, dizziness and confusion have been reported. If you experience dizziness or confusion, ask your healthcare professional whether it is safe for you to drive or operate machinery.

Eye problems

Retinal detachment has been reported in people with CMV retinitis both before and after treatment. It is not known whether ganciclovir causes retinal detachment. Keep all recommended eye examinations.

Allergic reactions

Serious allergic reactions, including anaphylaxis, have been reported. Seek urgent medical attention if you develop symptoms of a serious allergic reaction.

Fertility and cancer risk

Ganciclovir may cause temporary or permanent effects on fertility. Based on animal studies, it should also be considered potentially carcinogenic to humans.

Who Should Not Use Ganciclovir, and Precautions

Do not use ganciclovir if you have had a serious allergic reaction to ganciclovir, valganciclovir or an ingredient in the injection.

Doctors use extra caution in people who already have low blood counts or who receive other treatments that can lower blood counts.

Your healthcare team may monitor blood counts, platelets and kidney function before and during treatment. People with CMV retinitis may also need regular eye examinations.

Older adults

Kidney function can decline with age, so healthcare professionals may need to take extra care with dosing and monitoring.

Liver disease

The safety and effectiveness of ganciclovir have not been adequately established in people with hepatic impairment. Tell your doctor if you have liver disease.

Ganciclovir in Pregnancy, Breastfeeding and Fertility

Pregnancy

Animal studies have shown fetal harm and birth defects. Human pregnancy data are limited, so the risk cannot be determined with certainty. Tell your doctor if you are pregnant or planning a pregnancy. Your doctor will weigh the potential benefits and risks.

Effective contraception is recommended according to the prescribing information for people who can become pregnant and for males with partners who can become pregnant.

Breastfeeding

Breastfeeding is not recommended during treatment because of the potential for serious adverse effects in a breastfed infant. Talk with your healthcare professional about appropriate alternatives.

Fertility

Ganciclovir may impair fertility in both males and females. Discuss fertility concerns with your healthcare professional before treatment.

Ganciclovir Interactions and Other Medicines

Ganciclovir can interact with medicines that affect the kidneys, blood counts or seizure risk.

Important interactions include certain medicines such as imipenem-cilastatin, cyclosporine, amphotericin B, mycophenolate mofetil, other medicines that can suppress blood counts or affect the kidneys, didanosine and probenecid.

This list is not complete. Tell your doctor and pharmacist about all prescription medicines, over-the-counter medicines, vitamins and herbal products you use.
