Efficacy of the Drionic unit in the treatment of hyperhidrosis.

A portable iontophoretic device (the Drionic unit) has recently been introduced for the treatment of hyperhidrosis. Twenty-two patients with hyperhidrosis were treated at twenty-seven sites (axillae, palms, soles) with this unit. Sweat output was measured by use of Persprint paper and the data were quantified by an image analysis computer. The data clearly demonstrate the efficacy of the Drionic unit at all treatment locations in the great majority of subjects. One month posttreatment follow-up showed a statistically significant continued sweat inhibition at the palmar sites. Side effects were common, but none was severe enough to necessitate discontinuation of treatment. Based on the results of this study, we conclude that the Drionic unit appears to have a definite place in the treatment of hyperhidrosis.
