Famvir Special Precautions





Full Prescribing Info
Special Precautions
Patients with renal or hepatic impairment: Special attention should be paid to patients with impaired renal function as dosage adjustment is necessary (see DOSAGE & ADMINISTRATION and OVERDOSAGE). No special precautions are required for elderly patients with normal renal function and patients with mild or moderate hepatic impairment. Famciclovir has not been studied in patients with severe hepatic impairment. Conversion of famciclovir to the active metabolite penciclovir may be impaired in these patients resulting in lower penciclovir plasma conentrations, and thus possibly a decrease of efficacy of famciclovir (see PHARMACOLOGY under Actions.)
Transmission of genital herpes: Genital herpes is a sexually transmitted disease. The risk of transmission is increased during acute episodes. Patients should be advised to avoid intercourse when symptoms are present even if treatment with an antiviral has been initiated.
