The efficacy and safety of famciclovir have not been established as suppressive therapy in infants following neonatal HSV infections. In addition, the efficacy cannot be extrapolated from adults to infants because there is no similar disease in adults. Therefore, famciclovir is not recommended in infants.

If you have not had chickenpox, it's important that you avoid exposure to anyone known to have the infection -- or even crowds where you may come in contact with the infection, particularly if you are pregnant.

Nevertheless, if a shingles outbreak affects your or you notice any symptoms outside of the area of the outbreak, you should speak to your doctor right away. Clinical studies of Famciclovir tablets in patients with recurrent genital herpes did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently compared to younger subjects.

Following the oral administration of a single 500 mg dose of radiolabeled Famciclovir to 3 healthy male volunteers, 73% and 27% of administered radioactivity were recovered in urine and feces over 72 hours, respectively. Penciclovir accounted for 82% and 6-deoxy penciclovir accounted for 7% of the radioactivity excreted in the urine. Approximately 60% of the administered radiolabeled dose was collected in urine in the first 6 hours. Take Famvir exactly as prescribed.

Urinary excretion and renal clearance were correspondingly reduced. The inhibitory activity of acyclovir is highly selective due to its affinity for the enzyme thymidine kinase TK encoded by HSV and VZV. This viral enzyme converts acyclovir into acyclovir monophosphate, a nucleotide analogue. The monophosphate is further converted into diphosphate by cellular guanylate kinase and into triphosphate by a number of cellular enzymes. In vitro, acyclovir triphosphate stops replication of herpes viral DNA. This is accomplished in three ways: 1 competitive inhibition of viral DNA polymerase, 2 incorporation into and termination of the growing viral DNA chain, and 3 inactivation of the viral DNA polymerase. HSV or varicella zoster virus VZV infection. Fifty-one subjects were enrolled in the pharmacokinetic part of the study and received a single body weight adjusted dose of Famciclovir doses ranged from 125 mg to 500 mg. These doses were selected to provide penciclovir systemic exposures similar to the penciclovir systemic exposures observed in adults after administration of 500 mg Famciclovir. Based on the pharmacokinetic data observed with these doses in children, a new weight-based dosing algorithm was designed and used in the multiple-dose safety part of the study. Pharmacokinetic data were not obtained with the revised weight-based dosing algorithm. The steady-state pharmacokinetics of digoxin were not altered by concomitant administration of multiple doses of Famciclovir 500 mg three-times-daily. No clinically significant effect on the pharmacokinetics of zidovudine, its metabolite zidovudine glucuronide, or emtricitabine was observed following a single oral dose of 500 mg Famciclovir coadministered with zidovudine or emtricitabine.
