BACKGROUND/OBJECTIVES: There are no reliably effective, well-tolerated topical agents for the treatment of hyperhidrosis. We sought to evaluate the efficacy and tolerability of oxybutynin 3% gel in adolescents and young adults with primary focal hyperhidrosis. METHODS: Patients with severe axillary hyperhidrosis were treated with topical oxybutynin 3% gel for 4 weeks. Response to treatment was assessed by calculating change in Hyperhidrosis Disease Severity Score from baseline to weeks 1 and 4. Change in health-related quality of life was assessed using the Children's Dermatology Life Quality Index or the Dermatology Life Quality Index. Adverse effects were evaluated using patient diaries, investigator global review, and physical examination. RESULTS: Of 10 patients aged 13-24 enrolled, seven completed the study. Of those who completed the study, four (57.1%) reported reduction in axillary Hyperhidrosis Disease Severity Score at week 1 and all seven (100%) at week 4. Six patients (85.7%) reported reduction in Children's Dermatology Life Quality Index or Dermatology Life Quality Index score. Anticholinergic adverse effects were infrequent. The majority of treatment-related adverse events were mild to moderate in severity. One patient experienced a severe adverse event. CONCLUSION: Oxybutynin 3% gel reduced hyperhidrosis severity and improved health-related quality of life in this small pilot study. Safety and efficacy should be further evaluated in a large, prospective, placebo-controlled study.
