Herpes Zoster

The recommended dosage is 500 mg every 8 hours for 7 days. Therapy should be initiated promptly as soon as herpes zoster is diagnosed. No data are available on efficacy of treatment started greater than 72 hours after rash onset.

Herpes Simplex Infections

Recurrent genital herpes: The recommended dosage is 1000 mg twice daily for 1 day. Initiate therapy at the first sign or symptom if medical management of a genital herpes recurrence is indicated. The efficacy of Famvir® (famciclovir) has not been established when treatment is initiated more than 6 hours after onset of symptoms or lesions.

Suppression of recurrent genital herpes: The recommended dosage is 250 mg twice daily for up to 1 year. The safety and efficacy of Famvir therapy beyond 1 year of treatment have not been established.

Patients with Reduced Renal Function

In patients with reduced renal function, dosage reduction is recommended (see PRECAUTIONS, General).

Administration with Food

When famciclovir was administered with food, penciclovir Cmax decreased approximately 50%. Because the systemic availability of penciclovir (AUC) was not altered, it appears that Famvir may be taken without regard to meals.
