How Valtrex Works
Role
of Valtrex
Valtrex is used to treat herpes zoster
(shingles) and genital herpes. It
does not cure herpes infections, but
alleviates the pain associated with
herpes, helps sores to heal faster,
and prevents new sores from forming.
Valtrex is the brand name for valacyclovir,
which is an oral prescription antiviral
medication. This medication works
by hindering the reproduction of the
active herpes viruses in the body.
Valtrex is also used to treat oral
herpes and varicella-zoster viruses.
Valtrex comes in a pill, which is
to be taken orally. It is important
to start treatment as soon as you
feel the first sign of a cold sore,
such as tingling, itching, or burning.

cold sore. You may take Valtrex with
or without food. It is also important

directed and at regular intervals.
