[Successful treatment of diabetic gustatory hyperhidrosis with topical glycopyrrolate].

Gustatory hyperhidrosis is a condition characterised by excessive craniofacial sweating in relation to food intake and is associated with diabetic neuropathy. The existing guidelines for treatment of this condition include antiperspirants, oral anticholinergic treatment, ionophoresis, botulinum toxin injections and endothoracic surgery. In this case a patient with diabetes suffering from gustatory hyperhidrosis was treated successfully with topical glycopyrrolate, an anticholinergic agent applied directly on the affected area.
