Hyperhidrosis is a medical condition that causes excessive sweating. Sweating is a necessary bodily function. It cools the body, preventing you from overheating. However, people who have hyperhidrosis sweat even when the body does not need to be cooled down.
You may be a candidate for Botox for hyperhidrosis if your sweating fails to improve with prescription antiperspirants. During the treatment, small amounts of Botox are injected into the muscle in the axilla region on both sides. Botox injections block the nerve signals responsible for sweating, stopping the sweat glands from producing too much sweat. You should notice a significant reduction in underarm sweating within the first 4 weeks after treatment. Results usually last 6-8 months before treatment needs to be repeated.
