According to the International Hyperhidrosis Society, the three most common treatments for sweaty hands are antiperspirant, iontophoresis and Botox. In some cases, suffers use a combination of the three treatments to achieve the results needed.
The least invasive treatment for sweaty hands is the use of antiperspirant directly on the hands. If antiperspirants are ineffective, iontophoresis, which uses a tray of water and a specially designed medical device to induce a low-current electrical charge that is applied to the skin of the hands. This procedure can only be carried out by a trained medical professional, but it offers an 83% success rate. Finally, a doctor can inject Botox directly into the palms of the hands to inhibit sweat production. This procedure needs to be repeated every six months.
