BOTOX® (onabotulinumtoxinA) is injected into the skin to treat symptoms of severe underarm sweating (severe primary axillary hyperhidrosis) when medicines used on the skin (topical) do not work well enough in people 18 years and older.
In a clinical study, the duration of response in patients receiving BOTOX® treatment was 201 days, or 6.7 months. *Individual results may vary.
