Neurotoxin injections, to include Xeomin, Botox, and Dysport, are a new treatment option for people with hyperhidrosis. You may be a candidate for this treatment if your sweating fails to improve with prescription antiperspirants. Neurotoxins are FDA-approved for people who sweat excessively. It may also be used “off-label” to reduce sweating in other areas, such as the hands, feet, and face.
