Gustatory sweating is a more common manifestation of diabetes mellitus than is appreciated. It is a distressing problem that has been difficult to treat safely.
Daily topical application of glycopyrrolate roll-on lotion was offered as an alternative to oral anticholinergic agents to an 87-year-old woman with long-standing type 2 diabetes mellitus who complained of profuse sweating after eating.
Gustatory sweating was relieved by application of glycopyrrolate and reappeared when the glycopyrrolate was briefly withdrawn to confirm its therapeutic effect.
For moderate to severe symptoms of diabetic gustatory sweating, topical application of glycopyrrolate is safe, effective, well tolerated, and convenient.
