Upper Limb Spasticity in Adults

How XEOMIN Works

In adults with upper limb spasticity, there is an imbalance of signals from the brain to the muscles, which causes stiffness and spasms. This can lead to abnormal arm or hand positions, uncomfortable movement, and pain.1

XEOMIN is injected into muscles to help interfere with these signals. This helps decrease muscle stiffness and improve your ability to function using the affected muscles.2

Some stiffness and spasms may still occur, but in most patients less severely.

XEOMIN Helps Improve Upper Limb Spasticity Symptoms

In clinical studies, XEOMIN improved muscle tone and showed functional improvements 4 weeks after initiating treatment2*

3 out of four patient graphic

3 out of 4 patients showed at least "minimal improvement" in function with XEOMIN2*

43 percent graphic

43% of patients were rated as "much improved" (40%) or "very much improved" (3%) in function with XEOMIN2*

*Functional improvement was measured using the Global Impression of Change Scale (GICS), a global measure of a patient's functional improvement.
