Parameters associated with efficacy of epidural steroid injections in the management of postherpetic neuralgia: the Mayo Clinic experience.

Thirty percent of patients with postherpetic neuralgia (PHN) receiving conservative treatment report unsatisfactory pain relief. Epidural steroid injections (ESIs) are commonly used as a therapeutic intervention in these patients. In this study, we aimed to determine if there are variables that predict the efficacy of ESI in patients with PHN.

Premedication With Gabapentin Significantly Reduces the Risk of Postherpetic Neuralgia in Patients With Neuropathy.

Postherpetic neuralgia (PHN) is the most common complication of varicella zoster virus (VZV) reactivation and a cause of considerable physical and psychosocial morbidity. No known treatment effectively prevents the development of PHN in patients with VZV reactivation. In this study, our objective was to evaluate the efficacy of premedication with gabapentin for reducing the risk of PHN in patients with diabetic and nondiabetic neuropathy.
