Postherpetic neuralgia

Postherpetic neuralgia (PHN) is a potentially debilitating condition that has been associated with profound psychosocial dysfunction. It is the most common complication of herpes zoster infection, or shingles, in immunocompetent adults. Approximately 10% of patients develop the condition. PHN is particularly common in the elderly, with 60% of patients with shingles developing PHN at the age of 60, and 75% at the age of 70. This review discusses PHN clinical features and risk factors, as well as possible ways to prevent complications. An overview of the currently recommended treatment options is also provided.
