VALGANCICLOVIR VIATRIS contains the active ingredient valganciclovir. In the body valganciclovir rapidly changes to ganciclovir.

VALGANCICLOVIR VIATRIS belongs to a class of medicines used to prevent the growth of viruses.

VALGANCICLOVIR VIATRIS acts against a virus called cytomegalovirus or CMV (a type of herpes virus). It prevents this virus from growing and multiplying in the body. CMV causes infections, mainly in people with poor immunity. Poor immunity can be caused by HIV/AIDS or by medications taken after an organ transplant.

VALGANCICLOVIR VIATRIS is used to treat CMV eye infections (known as CMV retinitis) in AIDS patients, which, if left untreated can cause blindness. It is not a cure for CMV eye infections.

VALGANCICLOVIR VIATRIS is not effective against any underlying HIV infection.

VALGANCICLOVIR VIATRIS is also used to prevent CMV infection in patients following organ transplantation.

Your doctor, however, may have prescribed VALGANCICLOVIR VIATRIS for another purpose.

Ask your doctor if you have any questions about why VALGANCICLOVIR VIATRIS has been prescribed for you.


This medicine is available only with a doctor’s prescription.


Animal and other laboratory studies have shown VALGANCICLOVIR VIATRIS causes infertility, birth defects and cancer. It is possible that these effects may also occur in humans.

Things you must do

Tell all doctors, dentists and pharmacists who treat you that you are taking VALGANCICLOVIR VIATRIS.

See your doctor regularly so that your CMV disease, blood cell counts and any other potential side effects may be monitored carefully. If blood cell counts are low then this may reduce your ability to fight infection, or for your blood to clot efficiently. If left undetected these effects on blood cells may contribute to death or serious illness.

If you have a CMV eye infection, you must also see your doctor regularly to monitor the condition of your retina (part of the eye).

If you become pregnant while taking VALGANCICLOVIR VIATRIS, tell your doctor immediately.

Condoms should be used by sexually active men while taking VALGANCICLOVIR VIATRIS and for 90 days after stopping treatment.

Tell your doctor if for any reason you have not taken your medicine exactly as prescribed. Otherwise, your doctor may think that it was not effective and change your treatment unnecessarily.

Things you must not do

Do not take VALGANCICLOVIR VIATRIS to treat any other complaints unless your doctor tells you to.

Do not give VALGANCICLOVIR VIATRIS to anyone else even if they have the same condition as you.

Do not stop taking VALGANCICLOVIR VIATRIS or change the dosage without first checking with your doctor.

Be careful driving or operating machinery until you know how VALGANCICLOVIR VIATRIS affects you.
