Types of Treatment
After the initial outbreak* of genital herpes, 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 or orolabial herpes in people infected with HIV. 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.

When discussing treatment options with your doctor, be sure to discuss your lifestyle, how you feel about outbreaks, the pain and severity of your symptoms, and the frequency of your outbreaks. Be sure to talk with your doctor about the type of treatment (episodic or suppressive) that would be most appropriate for you.

For episodic and suppressive treatment, always take your medicine as prescribed by your doctor. If you are taking any other prescription or over-the-counter medications, please be sure to tell your doctor. No medication has been proven to prevent the transmission of genital herpes. It's important to know that FAMVIR will not prevent the spread of genital herpes to others. During an outbreak, you must avoid sexual contact, and use a condom in between outbreaks.

Efficacy of FAMVIR

• Episodic Treatment
  One clinical study showed that episodic treatment with FAMVIR significantly relieved all of the symptoms of a genital herpes outbreak. For many people, the duration of the symptoms associated with genital herpes, pain, burning, itching, and tenderness, was reduced. These same people also experienced a faster healing of sores compared to those taking a sugar pill.

• Suppressive Treatment
  Many people on twice-daily suppressive therapy with FAMVIR may go almost a year without experiencing an outbreak.
