Adverse Effects of Famciclovir
Famciclovir has been generally well tolerated. Headache, nausea and diarrhea have been reported. Like acyclovir, famciclovir has been associated with dose-related adverse effects on testicular function in animals, but not in humans. In female rats, 600 mg/kg/day of famciclovir for 2 years enhanced the incidence of mam- mary adenocarcinoma.
