If antiperspirants aren’t able to stop the floodgates, you could ask your doctor about getting Botox injections, which were FDA-approved in 2004 for treating hyperhidrosis. Another treatment known as the miraDry Procedure recently received FDA approval, and a handful of doctors are beginning to offer it across the country. “The miraDry Procedure eliminates sweat glands in the underarm safely and non-invasively, so people can expect lasting results and stop excessive underarm sweat from interfering with their lives," says Jeffrey Klein, MD, a dermatologic surgeon practicing in San Juan Capistrano and Newport Beach in Orange County, California. You can get the one- to two-hour treatment at a dermatologist’s office. The results are long-lasting since sweat glands don’t regenerate, but it calls for two treatments to reap maximum benefits.
