The effectiveness of tap water iontophoresis for palmoplantar hyperhidrosis using a Monday, Wednesday, and Friday treatment regime

Dermatol Online J. 2013 Mar 15;19(3):14.

Abstract

Primary focal hyperhidrosis is a benign condition of unknown etiology. Tap water iontophoresis has long been known to inhibit sweat production. The mechanism of reduced hyperhidrosis by iontophoresis is not completely clear. For operational convenience, our patients received their treatments at different intervals to those recommended by the manufacturer of the iontophoresis unit. We performed a retrospective audit to evaluate the effectiveness of tap water iontophoresis using this regimen. This new treatment regimen was effective at controlling palmoplantar hyperhidrosis. Minimal undesirable effects such as mild skin irritation and erythema were noted but none were severe enough to necessitate discontinuation of treatment. In conclusion, tap water iontophoresis is a safe and effective treatment of palmar and plantar hyperhidrosis when used on Monday, Wednesday, and Friday for 4 weeks. Continued treatment is needed to maintain the effect and many patients go on to purchase their own machines. This technique should be considered prior to systemic or aggressive surgical intervention.
