Treatment of axillary hyperhidrosis with botulinum‐A toxin

Abstract
Background Severe axillary hyperhidrosis is a source of great embarrassment and considerable emotional stress to individuals afflicted with this condition. Existing topical and surgical therapies are either ineffective or associated with unacceptable morbidity. We attempt to determine the effect of botulinum‐A toxin (Dysport) in the treatment of axillary hyperhidrosis. Patients and methods After visualization of hyperhidrosis using the iodine–starch test, 10 patients with axillary hyperhidrosis underwent intradermal injection with 125 units of Dysport on each axilla. Patients were observed for 7 months after treatment. Results The treatment was well tolerated without side‐effects. All patients experienced relatively complete anhidrosis of the axillary skin after about 1 week for periods ranging from 4 to 7 months. Conclusions Botulinum‐A toxin may offer a fast, safe, and highly effective therapeutic option for severe hyperhidrosis.
