Twenty-four patients with notalgia paresthetica were treated with topical capsaicin (Zostrix) in a concentration of 0.025 percent for four months. In approximately 70 percent of the patients who remained in the study, relief of pruritus was achieved up to the 90 percent level. In the majority of these patients pruritus returned when use of the medication was stopped. The history, causes, and prevalence of the condition are reviewed. This treatment is the first described that is relatively effective.
