In 2004, the U.S. Food & Drug Administration (FDA) approved BOTOX (onabotulinumtoxinA) for treating severe primary axillary hyperhidrosis (excessive sweating of the underarms) in adult patients who are unable to find medical relief using clinical-strength antiperspirants.
How it works
OnabotulinumtoxinA is a purified protein that temporarily blocks the chemical pathways responsible for triggering the body's sweat glands. By interrupting this chemical messenger at the local site, botulinum toxin pauses sweating in the treated areas.
What to expect
Botox injections for hyperhidrosis are shallow and highly localized, meaning the medication remains just below the surface of the skin where it is placed.
