OnabotulinumtoxinA is a natural, purified protein with the ability to temporarily block the secretion of the chemical that is responsible for "turning on" the body's sweat glands. By blocking, or interrupting, this chemical messenger, botulinum toxin "turns off" sweating at the area where it has been injected. Botox injections are very shallow, meaning that the medicine is injected just below the surface of the skin, where it remains.
Research demonstrates that treating excessive sweating of the armpits, hands, feet, head and face with onabotulinumtoxinA is safe and effective. When used to treat underarm excessive sweating.
Results start to be noticeable approximately 2 to 4 days after treatment with the full effects usually noted within 2 weeks. Dryness typically lasts 4 to 12 months but some studies have found it can last as long as 14 months.
Repeated treatment with Botox is safe and effective for hyperhidrosis and consistently results in meaningful, long-lasting improvements in an excessive sweating patient’s symptoms, daily functioning, and quality of life.
