There are several treatments for hyperhidrosis that a doctor may suggest. The most common would be an antiperspirant, which is applied to the skin and blocks the sweat glands in an attempt to get the body to stop producing sweat. A doctor might also suggest Iontophoresis or Botulinum toxin injections. Medication may be prescribed or surgery may be considered in some cases.
