Consult your doctor if you have any questions or concerns about your hyperhidrosis. When it comes to iontophoresis, here are some things to know:
- If the mineral content of the tap water is low, current flow is reduced, and the desired amperage (10 to 18 milliamps) may not be achieved. A teaspoonful of baking soda added and dissolved in each tray should remedy the problem.
- Patients need treatments every 2 to 3 days for 5 to 10 sessions before an effect is observed. Once euhidrosis is achieved the interval between treatments may be stretched out. Some patients need only treat themselves once every 2 to 4 weeks.
- Avoid treating patients who are pregnant, have pacemakers or implants, cardiac conditions, electrical sensitivity, or epilepsy.
- Do not treat a patient with a metal orthopedic pin, screw or rod. The current may be localized at the metal causing pain.
- Some patients experience irritation along the water line following treatment. Simple 1% hydrocortisone cream is usually sufficient to relieve this.
