New Procedure Makes Hyperhidrosis No Sweat

Small Study Finds Ultrasound Therapy Destroys Underarm Sweat Glands, Reduces Sweat Production

Excess Sweating: Other Options

Among the current options for treating excessive sweating:

  • Antiperspirants
  • Medications to prevent sweat glands from being stimulated
  • Botox, FDA-approved for excess sweating in 2004
  • Surgery to turn off the nerve signals that trigger excess sweating.
  • Iontophoresis, an FDA-approved procedure using electricity to block sweat glands
  • miraDry, approved by the FDA in 2011. A handheld device delivers electromagnetic energy to the sweat glands. "It takes the sweat glands to a temperature that results in irreversible damage," says Steve Kim, chief technology officer and founder of Miramar Labs, which makes it. The loss of the glands will not adversely affect body cooling, he says. The procedure costs $2,500 to $3,000, he says.

This study was presented at a medical conference. The findings should be considered preliminary as they have not yet undergone the "peer review" process, in which outside experts scrutinize the data prior to publication in a medical journal.
