Iontophoresis is really effective in treating hyperhidrosis. It can really help with people suffering from excessive sweating, however, they need to undergo 20- to 40-minute treatment sessions several times per week until sweating decreases to a desirable level. At that point, treatments are scheduled less frequently, usually about once per week.
Iontophoresis treatments must be done regularly before sweating increases to maintain results. Most people with sports injuries undergo a handful of 5- to 10-minute treatment sessions over the span of a week or two to promote healing. After that point, physical therapy, rest, and proper nutrition will continue aiding the healing process.
