The good news about Hyperhidrosis is that it can be successfully treated with Botox. This procedure is a simple one, a small amount of the medication is injected intradermally to interrupt the signal from the nerves to the sweat glands that cause excessive sweating. You should notice a significant reduction of sweating within a week and can last up to six months. Botox treatment for excessive sweating is often covered by private health plans.
