Hyperhidrosis of the palms has a significant negative impact on quality of life. There is no FDA-approved treatment; however, clinicians often use glycopyrronium cloth off-label for this indication despite the lack of published guidance on optimal method of application for treatment of palms. To compare the safety and efficacy of 4 different methods of application of glycopyrronium cloth to give clinicians guidance when treating palmar hyperhidrosis. This study, conducted completely virtually using live interactive telemedicine, compared application times of 15 minutes, 30 minutes, and overnight without occlusion and 30 minutes under occlusion. The primary endpoint was a decrease in the mean of the Hand Severity Score (HHS) after 4 weeks of once-daily application. Safety data, including local skin reactions and other adverse events, were tabulated by cohort. Of the application times and methods tested, 30 minutes without occlusion produced the greatest decrease in the HHS with an acceptable safety profile. The most common adverse event was unilateral mydriasis, which presumably occurred from inadvertent introduction of study drug into the eye despite multiple warnings to the subjects to avoid eye contact. A few subjects had adverse events presumably due to systemic absorption of the drug similar to those seen in the pivotal trials for treatment of axillary hyperhidrosis. Glycopyrronium cloth can be used successfully to treat palmar hyperhidrosis. Occlusion for 30 minutes had the poorest response presumably due to the increased sweating causing dilution of the study drug. gov: NCT04906655 J Drugs Dermatol. 2022;21(5):488-494. doi:10.36849/JDD.6688.
