What is Valcyte (valganciclovir)?
Valganciclovir is an antiviral drug. It works by preventing viral cells from multiplying in your
body. Valganciclovir will not cure CMV but it can help control the infection.
Valganciclovir treats cytomegalovirus (CMV) infection of the eye in patients with acquired
immunodeficiency syndrome (AIDS). Valganciclovir also prevents CMV infection in patients who have
received an organ transplant (kidney, heart, or kidney-pancreas).
Valganciclovir may also be used for purposes other than those listed in this medication guide.
Your doctor may have switched you from ganciclovir (Cytovene) to valganciclovir (Valcyte).
Be aware that 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. To avoid overdosage, take only as many valganciclovir tablets as your doctor has
prescribed. An overdose of this medication can cause serious illness.
What is the most important information I should know about Valcyte (valganciclovir)?
Valganciclovir (Valcyte) and ganciclovir (Cytovene) must never be taken together. If your
doctor switched you from ganciclovir (Cytovene) to valganciclovir (Valcyte), the number of pills you
use each day may change. To avoid overdosage, take only as many valganciclovir tablets as your
doctor has prescribed.
Using valganciclovir while you are pregnant may cause harm to the unborn baby. If a man
fathers a child while using this medication, the baby may have birth defects. Use an effective form of
birth control while you are using valganciclovir. If you are a man, use a condom to prevent pregnancy
during your treatment. Continue using condoms for at least 90 days after you stop using valganciclovir.
Do not use a tablet that has been accidentally broken. The medicine from a crushed or
broken tablet can be dangerous if it gets in your eyes, mouth, or nose, or on your skin. If you must
handle a broken tablet, ask your doctor or pharmacist how to handle and dispose of the tablet safely.
Valganciclovir can lower the blood cells in your body that control bleeding and help you fight
infection. Your blood will need to be tested on a regular basis. It is important that you not miss any
scheduled visits to your doctor. Contact your doctor right away if you have any bleeding or signs of
infection (fever, chills, body aches, or flu symptoms).
What should I discuss with my healthcare provider before taking
Valcyte (valganciclovir)?
Before taking this medication, tell your doctor if you have:
Tell your doctor if you are on hemodialysis or if you have recently had a

Valganciclovir is in the FDA pregnancy category C. This means that it is not known if it will

Do not use this medication without telling your doctor if you are pregnant. Tell your doctor if you
become pregnant during treatment.

has prescribed.
Take each dose with a full glass of water.
Take valganciclovir with food.
Take this medication for as many days as it has been prescribed for you even if you begin
to feel better. Your symptoms may start to improve before the infection is completely treated.
It is very important to take this medicine at the same time each day. To best treat your
condition, you should not miss any doses.
Do not crush or break a valganciclovir tablet. Do not use a tablet that has been accidentally
broken. The medicine from a broken tablet can be dangerous if it gets in your eyes, mouth, or nose, or

with plain water. If you must handle a broken tablet, ask your doctor or pharmacist how to dispose of
the tablet safely.
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.
Valganciclovir can lower the blood cells in your body that help you fight infections. This can
make it easier for you to bleed from an injury or get sick from being around others who are ill. To be
sure your blood cells do not get too low, your blood will need to be tested on a regular basis. It is
important that you not miss any scheduled visits to your doctor.
Store valganciclovir at room temperature away from moisture and heat.

Take the missed dose as soon as you remember. If it is almost time for the next dose, skip the
missed dose and take only the next regularly scheduled dose. Do not take extra
medicine to make up the missed dose.

your lower back or sides), or signs of liver damage (yellowing of the skin or eyes, severe and sudden
stomach pain, diarrhea, vomiting).
What should I avoid while taking Valcyte (valganciclovir)?
If you have AIDS, follow your doctor's instructions with respect to high-risk activities such as
unprotected sex and the sharing of needles.
Use birth control to prevent pregnancy while you are using
valganciclovir, whether you are a man or a woman. Valganciclovir use by either
parent can cause birth defects. If you are a man, use a condom to keep from causing a pregnancy
while you are taking valganciclovir. Continue using condoms for at least 90 days after you stop taking
