Famvir (Famciclovir) is a prescription medication that comes in the form of coated tablets with a dosage of 500 mg. It is used to treat various viral infections, particularly herpes simplex virus (HSV) and varicella-zoster virus (VZV). Famciclovir belongs to a class of medications known as antiviral drugs, which work by preventing the growth and spread of the virus in the body.

Indications and Uses

Famvir is commonly prescribed for the following conditions:

• Genital herpes
• Cold sores (herpes labialis)
• Shingles (herpes zoster)
• Recurrent outbreaks of herpes simplex virus

It is important to note that Famvir is not a cure for these viral infections but can help to reduce the severity and duration of symptoms, as well as prevent future outbreaks.

How to Take Famvir

It is essential to follow your healthcare provider’s instructions when taking Famvir. The usual dosage for adults is 500 mg. three times daily for 7 days when treating herpes zoster. For genital herpes, the recommended dose is 250 mg. twice daily for 5-10 days.

Take Famvir with food to help increase its absorption and reduce the risk of stomach upset. Swallow the tablets whole with a full glass of water. Do not crush, chew, or break the tablets unless instructed by your doctor.

If you miss a dose of Famvir, take it as soon as you remember. However, if it is almost time for your next dose, skip the missed dose and continue with your regular dosing schedule. Do not double up on doses to make up for a missed one.
