The iontophoresis procedure uses electricity to temporarily turn off the sweat glands. This procedure has been used for several decades to treat palmar and plantar hyperhidrosis, or sweaty hands and feet.
During the procedure, your hands or feet are placed into water and a gentle current of electricity is passed through it. The electricity is gradually increased until the patient feels a light tingling sensation. The therapy lasts about 10 to 30 minutes and may require several sessions a week.
While this treatment works on some patients, it may be ineffective on others. Serious side effects are uncommon, but you may suffer from skin irritation. There are several iontophoresis devices on the market including Dridonic, Fischer, Hidrex and Idromed. It may be possible to rent a unit on a weekly basis to assess its efficacy.
