How is excessive sweating treated?

There are a couple of medical procedures that can control excessive sweating. Iontophoresis uses electricity to turn down sweat glands and works well on hands and feet. It’s an effective solution but a temporary one. Follow-up treatments will be necessary.

Another potential treatment is Botox, which can help block the nerves involved in sweating. Again, Botox is effective and temporary, lasting around four months.

More recently a microwave technology (MiraDry) has become available for underarm sweating. This device uses a heating and cooling sequence to selectively target sweat glands. The technique is noninvasive but does require a local anesthetic. Sweating typically is reduced by 70%, and the results are long-lasting.

Liposuction is another approach. In this procedure, a small cannula (a small metal straw-like device) is introduced through a small incision. A to-and-fro motion is then applied by the doctor to damage and remove the glands.
