This study evaluated the efficacy of topical oxybutynin 10% gel in treating 61 patients with primary focal hyperhidrosis. The gel was applied to the right or left axilla, palms or soles vs. a placebo compound to the contralateral side for 30 days. A blinded visual grading of the change in starch- iodine tests was performed by 2 non-involved physici- ans. The Hyperhidrosis Disease Severity Scale (HDSS) and Dermatology Life Quality Index (DLQI) questionn- aires were administered before and after treatment. The patients rated their satisfaction with treatment. Fifty-three patients completed the 4-week treatment. Sweat reduction in the drug-treated sweating areas was higher than in the control-treated areas. There was a significant mean improvement in pre- and post- treatment HDSS and DQLI (pā€‰ =ā€‰0.001 for both). Thirty- nine subjects (74%) reported moderate-to-high satis- faction. Twice-daily topical application of oxybutynin 10% gel appears to be an effective, safe and well-tole- rated treatment for focal primary hyperhidrosis.
