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

The effects of prednisone, oral acyclovir, and radiotherapy were compared with placebo in the prevention of post-herpetic neuralgia.

Radiotherapy was of no value in either the acute or post-herpetic phase.
