Antiperspirants are the first method of attack in stopping sweaty armpits, according to the International Hyperhidrosis Society of SweatHelp.org. Changing clothing made of certain materials can also help to reduce sweaty armpits.
Regular over-the-counter antiperspirants can be found to be effective in some cases, notes the International Hyperhidrosis Society. There are "clinical strength" antiperspirants available without a prescription that often prove as powerful as prescription antiperspirants. Dri and Secret Clinical are the names of two brands that have shown to have the same efficacy as prescription antiperspirants, with less irritation. These are easily found at the local drugstore. It is important to apply antiperspirants on dry skin at night before bed.
Injecting botox into the underarms by an experienced professional is proven to be quite effective in reducing sweaty armpits for months at a time, explains the International Hyperhidrosis Society. A clinical study involving 322 patients yielded results with over 50 percent of patients having reduced swelling for a minimum of 201 days, and some for over a year.
MiraDry is an FDA approved outpatient procedure that greatly reduces underarm perspiration, states miraDry.com of MiramarLabs, Inc. This treatment is non-invasive and permanently eliminates the sweat glands in the armpit. If these remedies and procedures fail to relieve or cure the problem of sweaty armpits, surgical procedures are available, notes the International Hyperhidrosis Society.
