How do over-the-counter antiperspirants help treat hyperhidrosis?

ANSWER

Over-the-counter antiperspirants containing a low dose of metal salt (usually aluminum) are usually tried first because they are readily available. Antiperspirants containing aluminum chloride (for example Certain Dri) may be more effective when other antiperspirants have failed.

  • Prescription strength antiperspirants, which contain aluminum chloride hexahydrate.
  • Iontophoresis, a device which passes ionized tap water through the skin using direct electricity.
  • Oral medications, Anticholinergics reduce sweating.
  • Botox (botulinum toxin)-A, has been approved in the U.S. by the FDA for treating excessive axillary (underarm) sweating.
  • miraDry. This technique uses microwave energy to permanently kill sweat glands.
  • Lasers. Lasers can target and kill the underarm sweat glands.
  • Surgery. A procedure called thoracic sympathectomy may be considered as a last resort.
