Hyperhidrosis (excessive sweating) is uncomfortable, displeasing and can be detrimental to one's self-esteem. 

One of the most effective ways to treat excessive underarm sweating is to inject small doses of Botox to the underarm (axilla), which blocks excessive sweat gland activity.  To keep excessive sweating under control, it is recommended to have injections every four to six months.  Some people may experience longer lasting results, up to one year.
