Comparative Study Clinical Trial
Open-label study of valacyclovir 1.5 g twice daily for the treatment of uncomplicated herpes zoster in immunocompetent patients 18 years of age or older.
Herpes zoster (shingles) is a common disease caused by a reactivation of the latent varicella-zoster virus (chickenpox), which resides in the dorsal root ganglia. Valacyclovir HCl, the L-valyl ester of acyclovir, is an antiviral drug that is used to accelerate the resolution of the herpes zoster rash and associated pain and reduce the duration of postherpetic neuralgia. ⋯ Oral valacyclovir 1.5 g bid is safe and effective for the treatment of uncomplicated herpes zoster in immunocompetent patients over 18 years of age. Twice-daily dosing may help increase patient compliance and therefore increase the effectiveness of treatment of the acute herpes zoster rash and the prevention of ZAP.
