Famciclovir Oral Uses
This drug is used in certain patients to treat or help prevent outbreaks of herpes simplex on the skin (mouth, lips, genitals, anus). Famciclovir is also used to treat outbreaks of shingles (herpes zoster). The viruses that cause these infections are similar. They live in the body quietly until an outbreak is triggered. Famciclovir is not a cure for the infections, but treating an outbreak can speed up healing of the sores, decrease pain, and lower the risk of complications from the virus (e.g., whole body infection, brain infection, persistent pain after sore healing).
How To Use Famciclovir Oral
Take this medication by mouth with or without food, usually 2-3 times daily or as directed by your doctor. It is very important to continue taking this medication exactly as prescribed by your doctor.
Dosage is based on your kidney function, medical condition, and response to therapy.
This medication works best when the amount of drug in your body is kept at a constant level. Therefore, take this drug at evenly spaced intervals. To help you remember, take it at the same times each day.
Do not take more or less of this drug than prescribed or stop taking it even for a short time unless directed to do so by your doctor. Skipping or changing your dose without approval from your doctor may decrease the effectiveness of the drug.
Inform your doctor if your outbreak does not get better or worsens.
