How is herpes zoster treated with Famvir?
Herpes Zoster (shingles) is an acute infection that frequently leads to postherpetic neuralgia (PHN), a severe and painful condition. Famvir is used to shorten the length of the herpes zoster infection, speed up the healing of the skin sores, and shorten the duration of PHN in those patients who develop PHN. Famvir is used for 7 days, but must be started within 72 hours of the appearance of the herpes zoster rash.
