Sweaty feet or plantar hyperhidrosis is a common condition affecting 3% of Australians. miraDry can not treat sweaty feet due to the fact that tendons and nerves maybe damaged by the pulsed electromagnetic energy of miraDry. Treatment for excessive feet sweating can be successful with iontophoresis glycopyrrolate treatments.

How do we approach managing plantar hyperhidrosis / wet feet?
Next to compensatory hyperhidrosis, plantar hyperhidrosis or sweaty feet is one of the more difficult areas to treat. Simple measures such as changing socks frequently, together with managing any secondary infection as well as the use of innersoles is super important. Most patients who see us would have already tried, and failed Driclor and other antiperspirants.
The use of glycopyrrolate iontophoresis is the next step- it can be highly effective in some patients. Sweat stopping treatments is not advisable as the cost-benefit ratio is not there.
miraDry is an excellent treatment for patients with underarm sweating- axillary hyperhidrosis, but can not be used to treat sweaty hands/ feet. There are too many nerves and tendons in these areas, and electromagnetic waves in these areas are not recommended.
