Overview:  Botulinum products work to limit chronic sweating by inhibiting the release of acetylcholine.  This in turn block contraction of fibers within the sweat glands, which in turn limits chrnoic sweating.  For patients that have excessive sweating (hyperhidrosis) to the underarms, Botox is a great treatment option.

Botox Dosing:  Generally, 50 units are administered in EACH underarm with multiple injection sites.  Discomfort is easily managed with ice packs. 

Duration of Botox/Dysport Treatments:  The expectation is anywhere from 4 to 9 months with the average being 6 months.

Standard of Practice:  The use of Botox for the treatment of axillary hyperhidrosis was FDA-approved in 2004.
