Famvir
(famicyclovir) is an antiviral drug. Famvir slows the growth
and spread of the herpes virus so that the body can fight off
the infection. Famvir shortens the length of time that herpes
symptoms are present. Famvir is used to treat infections caused
by herpes viruses including shingles, genital herpes, and cold
sores (in people with HIV).
Take
Famvir (famciclovir) 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.
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.
Precautions
Do not take Famvir if you are allergic to
penciclovir (Denavir) without first talking to your doctor.
Before taking Famvir, 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.
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 Famvir unless otherwise directed
by your doctor.
