WHAT TO KNOW
Treatment with Famvir should be started as soon as possible
after the first appearance of symptoms (e.g. tingling,
burning, blisters). Take all of the Famvir 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. 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.
WHAT IS Famvir
Famvir is an antiviral drug. It slows the growth and
spread of the herpes virus so that the body can fight
off the infection. Famvir shortens the length of time
symptoms are present. Famvir is used to treat infections
caused by herpes viruses including shingles, genital
herpes, and cold sores (in people with HIV)
HOW TO TAKE Famvir
Take Famvir exactly as directed by your doctor. If you
do not understand these directions, ask your pharmacist,
nurse, or doctor to explain them to you. Treatment
with Famvir should be started as soon as possible after
the first appearance of symptoms (e.g. tingling, burning,
blisters). Take each dose with a full glass of water.
Famvir can be taken with or without food. Taking Famvir
with food may decrease stomach upset. Take all of the
Famvir that has been prescribed for you even if you
begin to feel better
MISSED DOSE
Take the missed dose as soon as you remember. However,
if it is almost time for the next regularly scheduled
dose, skip the missed dose and take the next one as
directed. Do not take a double dose of this med unless
otherwise directed by your doctor.
OVER DOSE
Seek emergency medical attention. A Famvir overdose has
no known symptoms, but an overdose of acyclovir (Zovirax),
which is a similar drug, may cause seizures, hallucinations,
and kidney damage (decreased urine production).
SIDE EFFECTS
Stop taking Famvir and seek emergency medical attention
if you experience:
an allergic reaction (difficulty breathing; closing
of your throat; swelling of your lips, tongue, or face;
or hives)
Other, less serious side effects may be more likely to
occur. Continue to take Famvir and talk to your doctor
if you experience:
nausea or vomiting
a headache
diarrhea
dizziness, tingling in your hands or feet
itching
PRECAUTIONS
Do not take Famvir if you are allergic to penciclovir
(Denavir) without first talking to your doctor. Before
taking this med, tell your doctor if you have kidney
disease. You may need a dosage adjustment or special
monitoring during treatment with Famvir.
DRUG INTERACTIONS
Probenecid (Benemid) may increase the effects of Famvir
and lead to dangerous side effects. You may need a
dosage adjustment or special monitoring during treatment
if you are taking probenecid.
