Hyperhidrosis is a condition that causes the sweat glands to enlarge and cause excessive sweating. It can occur in sweat glands all over the body, including the hands and feet, but it is most common in the underarm area. Excessive underarm sweating or axillary hyperhidrosis can take a toll on one’s self-esteem and affect their quality of life. There is no cure yet for primary axillary hyperhidrosis but the good news is it’s possible to reduce sweating and treat hyperhidrosis with a number of treatment options to choose from. More importantly, excessive sweating is a medical condition so hyperhidrosis treatments must be performed by a professional.

A prescription called Drysol can be an effective remedy for treating excessive sweating. Drysol is a topical antiperspirant with 20% aluminum chloride that works by affecting the cells that produce sweat, causing the enlarged sweat glands to shrink down to their normal size. Injections of Botox (a purified form of botulinum toxin) are also an effective treatment for hyperhidrosis but do require continued maintenance. Botox is a popular treatment for reducing fine lines and wrinkles, but doctors can also use botox to treat hyperhidrosis.

The series of injections needs to be repeated about 2 to 3 times a year and is typically not covered by insurance. When Botox is injected directly into muscles surrounding the enlarged sweat glands in the axillary areas (armpits), it temporarily inhibits the sweat glands from producing excess sweat. Response is usually seen within 7 to 10 days after injections, and several sessions may be needed to complete the series and achieve the best results. You may go home immediately after your botox for excessive sweating treatment but you should avoid exercise or have hot baths or showers for the rest of the day. Your aesthetician may recommend follow up treatments to touch up any missed areas and to check for side effects. 

With Botox, you can stop excessive sweating in your underarms. Schedule a consultation with our doctors at Knott Street Dermatology in Portland, Oregon today and start your journey to self-confidence.
