shingles, genital herpes, and cold sores (in people with HIV).
Famvir Directions
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.
Famvir 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.
Famvir 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.
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 of Famvir
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.
