Note
The following information is intended to supplement, not substitute for, the
expertise and judgment of your physician, pharmacist or other healthcare

safe, appropriate, or effective for you. Consult your healthcare
professional before using this drug.
Uses
Valtrex is an antiviral agent most commonly used in the treatment of herpes
zoster (shingles), genital herpes and is also being used for herpes simplex
(cold sores). It slows the growth and spread of the herpes virus so that the
body can fight off the infection and lessens the symptoms of these
infections and shortens the length of time you are sick. It may also be used
to treat other conditions.
How to Use
Take as directed by your doctor. Valtrex can be taken with or without food.
Taking Valtrex with food may decrease stomach upset. Usually take 1 tablet 2
times daily by mouth for acute outbreaks and 1 tablet daily as a maintenance
dose if needed. Do not skip doses or stop taking this without your doctor's
approval. Stopping therapy too soon may result in ineffective treatment.
Take all of the Valtrex that has been prescribed for you even if you begin
to feel better. Your symptoms may start to improve before the infection is
completely treated.
Side Effects
Possible side effects of taking Valtrex are nausea, vomiting, headache, loss
of appetite, weakness, stomach pain or dizziness may occur the first several
days as your body adjusts to the medication. Notify your doctor if your
condition does not appear to improve or you experience a worsening of
symptoms while taking this medication. Talk to your doctor about any side
effect that seems unusual or that is especially bothersome.
Precautions
Do not take Valtrex without first talking to your doctor if you are allergic
to Acyclovir (Zovirax).Tell your doctor if you have any kidney disease,
blood disorders or if you have any allergies. Valtrex should be used only if
clearly needed during pregnancy. Do not take this medication without first
talking to your doctor if you are breast-feeding a baby. If you plan on
becoming pregnant, discuss with your doctor the benefits and risks of using
this medicine during pregnancy.
Drug Interactions
Tell your doctor of any over-the-counter or prescription medication you may
take including cimetidine (Tagamet, Tagamet HB) or probenecid (Benemid), as
they may increase the effects of Valtrex and possibly lead to dangerous side
effects. Talk to your doctor and/or pharmacist before taking any
prescription or over-the-counter medicines, including herbal products.
Notes
Herpes infections are contagious and you can infect other people, even
during treatment. Avoid letting infected areas come into contact with other
people. Wash your hands frequently to prevent transmission. Do not share
Valtrex with others for whom it was not prescribed, since they may have a
problem that is not effectively treated by this drug.
Missed Dose
If you miss a dose of this medicine, take the dose as soon as you remember.
However, if it is almost time for the next regularly scheduled dose, skip
the missed dose and take only your next regularly scheduled dose. Do not
take a double dose.
Storage
Store this medicine at room temperature in a tightly-closed container, away
from heat, moisture, and light. Keep this and all medications out of the
reach of children.
