Lontophoresis used in treating excessive hand sweating
Iontophoresis works by inducing electrical changes in the sweat glands that disrupts the sweat production. This works by placing the affected areas in tap water. A small electric current is then passed through the skin.
This device works well for mild to moderate forms of hyperhidrosis. However, its drawback is the time that is required to do the treatments. The treatments also have to be continued indefinitely. Treatment starts with twenty minutes on a daily basis and is tailored to individual symptoms.
Side effects of iontophoresis are few. Affected areas may crack, become too dry or fissured. If this occurs the frequency of treatments should be decreased. Most patients report a tingling sensation and mild pain especially in the beginning of the treatments.
