Abstract

&NA; Treatment of craniofacial hyperhidrosis currently consists of thoracic sympathectomy, which is not widely available. Oral anticholinergic agents and &bgr;‐blockers may be effective but also carry significant side effects. We describe a healthy, active 27‐year‐old male resident physician who had excessive facial sweating with minimal exertion or stress. The sweating was especially pronounced on the forehead, nose, and upper lip. Daily topical application of a 0.5% glycopyrrolate solution to the face and forehead was offered. After the first treatment, facial sweating was significantly reduced and was well controlled under stressful situations, without any discomfort to the skin. No loss of efficacy was seen after multiple face washings. Facial hyperhidrosis recurred after withdrawal of the glycopyrrolate for 2 days, confirming its therapeutic effect. Two years later, he continues to use glycopyrrolate as needed. We conclude that topical glycopyrrolate is effective in treating craniofacial hyperhidrosis and is associated with few adverse effects.
