Abstract

Herpes zoster (HZ), also known as shingles, is a painful vesicular rash resulting from reactivation of the virus that also causes chickenpox – Varicella zoster virus (VZV). Typically, the rash runs its course in a matter of 4-5 weeks. The pain, however, may persist months, even years, after the skin heals. This phenomenon is known as postherpetic neuralgia (PHN). Often described as an intense burning, itching sensation, this pain can be significant to the point of being debilitating, and as such can greatly affect quality of life. Although shingles is generally regarded as a self-limited condition, the fact it can take several weeks to resolve and has the potential for development of complications such as PHN presents a challenge to clinicians. Many treatment options are available, each offering variable levels of efficacy. Conventional therapies include prescription antivirals, corticosteroids, and analgesics, both oral and topical. Other considerations include use of over-the-counter anti-inflammatory agents, physiotherapy, and nerve block injections. This article reviews herpes zoster and postherpetic neuralgia, and presents the most effective conventional treatment options currently available, as well as select botanical, nutritional, and other considerations that may be beneficial in the management of this condition.
