Drug Uses
Famvir is an oral antiviral prescription medication
that is prescribed for: treatment of recurrent genital
herpes in otherwise healthy patients; suppression of
recurrent genital herpes in otherwise healthy patients;
treatment of recurrent herpes simplex virus infections
(genital herpes and cold sores) in HIV-infected patients.
How Taken
Famvir can be prescribed in one of three ways: -Episodic
treatment: your doctor treats an outbreak of genital
herpes as it occurs. The usual dose of Famvir is one
125-mg pill, twice a day, for 5 days. -Suppressive treatment:
if you have frequent or severe outbreaks, you take one
250-mg pill, twice a day, for up to 1 year to suppress
the genital herpes virus and help to prevent outbreaks.
-Patients with HIV: Famvir is the only prescription
oral antiviral therapy indicated for treating genital.
In patients with herpes simplex and HIV, the dose of
Famvir is 500 mg, twice a day, for 7 days. Famvir can
be taken with or without food. Warnings/Precautions
Do not take Famvir if you are allergic to penciclovir
(Denavir) without first talking to your doctor. Before
taking this medication, tell your doctor if you have
kidney disease. You may need a dosage adjustment or
special monitoring during treatment with Famvir. Famvir
(Pregnancy Category B) should be used during pregnancy
only if the benefit to the patient clearly exceeds the
risk to the fetus. Missed Dose
IF YOU MISS A DOSE OF THIS MEDICINE, take it as soon
as possible. If it is almost time for your next dose,
skip the missed dose and go back to your regular dosing
schedule. Do NOT take 2 doses at once. Possible 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, or itching. Storage
Store between 15C and 30C (59F and 86F) and out of reach
of children. Overdose
Seek emergency medical attention. A Famvir overdose
has no known symptoms, but an overdose of Famvir
(Zovirax), which is a similar drug, may cause seizures,
hallucinations, and kidney damage (decreased urine production).
More Information
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. For more information, talk to your doctor,
pharmacist or health care provider. Disclaimer
