Xeomin® (incobotulinumtoxinA), made by Merz Pharmaceuticals, is approved by the US FDA for the treatment of adults blepharospasm. IncobotulinumtoxinA is made from the bacteria that causes botulism. Botulinum toxin blocks nerve activity in the muscles, causing a temporary reduction in muscle activity.
Xeomin® contains a form of botulinum toxin known as incobotulinumtoxinA, which varies slightly from the chemical composition of BOTOX® Cosmetic and Dysport. When injected into the underlying muscle, Xeomin® blocks the release of a wrinkle-causing chemical called acetylcholine. While Xeomin® doesn’t prevent all facial muscles from contracting, it does decrease the force with which the targeted muscles contract when you scowl, sneeze or otherwise contort your face.
