The below caught my eye, especially since both times I got a Robinul prescription, my doctor had to be persuaded by me that it works for hyperhidrosis. And one of these doctors was a dermatologist!
He also notes there have been multiple reports on the use of oral glycopyrrolate for the treatment of hyperhidrosis.
“Anticholinergic therapy for hyperhidrosis is not a new concept, but there are new data showing glycopyrrolate is safe and effective when used in a low dose regimen,” Dr. Levine says. “With just modest side effects and seemingly favorable safety with long-term use, perhaps it may replace more costly and difficult treatments such as iontophoresis , sympathectomy and even onabotulinumtoxinA (Botox, Allergan) injections.”
