Botox® is a purified derivative of botulism toxin, a powerful neurotoxin. It is best known as a treatment for facial wrinkles, but can also be used for the treatment of hyperhidrosis. Botox blocks neuromuscular transmission by inhibiting the release of the neurotransmitter acetylcholine. Since the nerves that activate the sweat glands use acetylcholine as their neurotransmitter, blocking that pathway will lead to a reduction in sweating wherever Botox is injected.
Botox injections are as effective as surgery at reducing excessive sweating, but the effects wear off in four to six months. Patients may therefore need the injections two or three times a year, which can be costly. Botox injections offer a temporary cure for axillary hyperhidrosis, whereas the surgical cure is permanent.
