LAHAINA, HAWAII – Hyperhidrosis affects nearly 5% of the U.S. population, and in a survey of U.S. teenagers, about 17% reported excessive sweating, Jashin Wu, MD, said at the Hawaii Dermatology Seminar provided by the Global Academy for Medical Education/Skin Disease Education Foundation.

In an interview with MDedge reporter Bruce Jancin, Dr. Wu, founder of the Dermatology Research and Education Foundation, Irvine, Calif., discussed the off-label use of oral agents to treat hyperhidrosis. Dr. Wu said he is a fan of oral glycopyrrolate in particular, which he tends to use even earlier than suggested in the International Hyperhidrosis Society guidelines.

Glycopyrrolate is available in 1 mg and 2 mg tablets; Dr. Wu starts patients at a dose of 1 mg twice a day, escalating by 1 mg per week until the “desired effects occur” or the patient has problems tolerating treatment because of side effects.

Other oral options include oxybutynin and propranolol. Sofpironium bromide, an analog of glycopyrrolate, is in the pipeline, he said.

During the interview, Dr. Wu discussed mydriasis, an adverse effect associated with both topical and systemic anticholinergic treatment. In the two pivotal phase 3 randomized trials of prescription glycopyrronium cloth (Qbrexza) for axillary hyperhidrosis, the incidence of mydriasis was 6.8% in 463 patients on active treatment for 4 weeks. Three-quarters of cases were unilateral. The mydriasis resolved without permanent treatment discontinuation in 27 of the 31 patients (J Am Acad Dermatol. 2019 Jan;80[1]:128-138.e2).

“The most important point is that patients need to be educated that they need to wash their hands very well after they apply it to the affected areas” to prevent accidental medication contact with the eyes, he advised.

Alarm bells can go off when a patient with anticholinergic therapy–induced mydriasis presents to an ED without mentioning their treatment status, Dr. Wu observed.
