It seems that the power of electricity is often an overlooked option in the treatment of palmar and/or plantar hyperhidrosis. While iontophoresis is far from being a new option, it remains one of the most effective treatments. Few clinicals studies corroborate this but they all demonstrate convincing results. One of the more recent studies dates back about a dozen years and showed that more than one hundred (112 to be exact) experienced a greater than 80% reduction in the sweating of their palms. These observations came after 8 treatments and return of symptoms occured on average 35 days after the last treatment.
Combining iontophoresis with the nighttime use of a high-strength antiperspirant such as DryDerm is also recommended for greater efficacy. This strategy also reduces the frequency of iontophoresis treatments.
