What is Valcyte (valganciclovir)?
Valganciclovir is an antiviral drug. It works by preventing viral cells from multiplying in your body.
Valganciclovir is used in adults to prevent infection with cytomegalovirus (CMV) that may occur after an organ transplant (heart, kidney, or pancreas). Valganciclovir is also used to treat CMV infection of the eye in adults with acquired immunodeficiency syndrome (AIDS).
Valganciclovir is used in children at least 4 months old to prevent CMV infection after a kidney transplant. Valganciclovir is also used in children at least 1 month old to prevent CMV disease after a heart transplant.
Valganciclovir will not cure CMV but it can help control the infection. Valganciclovir is not for treating CMV that a baby is born with.
Valganciclovir may also be used for purposes other than those listed in this medication guide.
What is the most important information I should know about Valcyte (valganciclovir)?
Valganciclovir has caused birth defects in animal studies. Do not use valganciclovir without telling your doctor if you are pregnant.
Use birth control to prevent pregnancy, whether you are a man or a woman. Valganciclovir use by either parent may cause birth defects. A man taking valganciclovir should use a condom during treatment, and for at least 90 days after treatment ends.
Serious infections may occur during treatment with valganciclovir. Stop using this medicine and call your doctor right away if you have signs of infection such as: fever, chills, sore throat, weakness, cold or flu symptoms, painful mouth sores, pale skin, easy bruising or bleeding, dry cough, weight loss, or trouble breathing.
Valganciclovir (Valcyte) and ganciclovir (Cytovene) must never be taken together.
What should I discuss with my healthcare provider before taking Valcyte (valganciclovir)?
You should not use this medicine if you are allergic to valganciclovir or ganciclovir (Cytovene).
Valganciclovir (Valcyte) and ganciclovir (Cytovene) must never be taken together.
Your doctor may have switched you from ganciclovir (Cytovene) to valganciclovir (Valcyte). The strength of these two medications is different. A valganciclovir tablet contains more medicine than a ganciclovir capsule. You may not need to use as many valganciclovir tablets as you did ganciclovir capsules. Take only the number of valganciclovir tablets your doctor has prescribed.
To make sure valganciclovir is safe for you, tell your doctor if you have:
kidney disease (or if you are on dialysis);
a blood cell disorder (such as anemia or low levels of platelets in your blood); or
if you are receiving radiation treatment or drugs that weaken your immune system (such as cancer medicine or steroids).
Valganciclovir can cause birth defects. Do not use if you are pregnant, and tell your doctor right away if you become pregnant. You may need to have a negative pregnancy test before taking valganciclovir. Use effective birth control while you are taking valganciclovir and for at least 30 days after your treatment ends.
HIV can be passed to your baby if you are not properly treated during pregnancy. Take all of your HIV medicines as directed to control your infection. Valganciclovir will not prevent congenital (inherited) CMV in a newborn baby.
If a man fathers a child while using valganciclovir, the baby may have birth defects. Use a condom to prevent pregnancy during your treatment. Continue using condoms for at least 90 days after you stop using valganciclovir.
This medication can affect fertility (your ability to have children), whether you are a man or a woman.
You should not breast-feed while you are taking valganciclovir. Women with HIV or AIDS should not breast-feed a baby. Even if your baby is born without HIV, the virus may be passed to the baby in your breast milk.
How should I take Valcyte (valganciclovir)?
Follow all directions on your prescription label. Do not take this medicine in larger or smaller amounts or for longer than recommended.
Valganciclovir tablets are for adults or children, but valganciclovir liquid is only for children. Adults should not use the oral solution or the dose may not be correct.
Take valganciclovir with food.

Do not crush or break a valganciclovir tablet. The medicine from a crushed or broken pill can be dangerous if it gets in your eyes or on your skin. If this occurs, wash your skin with soap and water or rinse your eyes with water. Ask your doctor or pharmacist how to safely handle and dispose of a broken tablet.
While using valganciclovir, you may need frequent blood tests.
You should have your eyes checked at least every 4 to 6 weeks while you are using valganciclovir. Your doctor may want you to have eye exams more often.
