Prevention of post-herpetic neuralgia. Evaluation of treatment with oral prednisone, oral acyclovir, and radiotherapy

Abstract

The effects of prednisone, oral acyclovir, and radiotherapy were compared with placebo in the prevention of post-herpetic neuralgia. No treatment used was able to prevent, with statistical significance, post-herpetic neuralgia, although prednisone and acyclovir showed some pain reduction in the acute phase. Radiotherapy was of no value in either the acute or post-herpetic phase.
