Patient Education

Iontophoresis is a procedure used to treat excessive sweating in the hands or feet. The procedure involves one or a series of short, 10- to 20-minute sessions in the doctor's office during which a light electrical current is passed through water into the feet. The current is gradually increased until the patient experiences a slight tingling sensation. It is believed, although not clinically proven, that this process plugs up the sweat glands.
