Postherpetic Neuralgia in Herpes Zoster

摘要

To the Editor: In his Clinical Crossroads article discussing herpes zoster, Dr Whitley1 stated that our Cochrane review2 reported no benefit of valacyclovir for prevention of postherpetic neuralgia (PHN) at 4 or 6 months after rash onset. However, this is not accurate; our review did not include any trials of valacyclovir.
