For years it has been used to get rid of facial wrinkles, and when doctors noticed it stopped sweating in the face, they decided to try it as a remedy for excessive sweating. The procedure requires 30-60 injections right under the skin. The Botox paralyzes the sweat glands and will last anywhere from three to twelve months. Patients usually have one hand done at a time to see if the procedure is effective. If it succeeds, they will go back to get the other hand done.
Patients can also have injections to help sweaty feet, armpits and faces.
But for patients who suffer with sweaty palms, it is money well spent.
