The FDA has approved Botox for use in treatment of muscle spasms in flexor muscles, including muscles in the elbow, wrist and fingers. This condition commonly occurs as a result of stroke, brain injury or multiple sclerosis. Spasticity causes muscles to become stiff and is very painful, having a negative effect on patients’ daily activities. Botox works by preventing nerves from activating muscles, temporarily halting the muscle’s movement and spasticity. It is already approved for use cosmetically to reduce fine lines and wrinkles, as well as for use in treating underarm sweating and cervical dystonia, a condition that causes neck spasms. It is currently being studied for use in treating a variety of other conditions, including migraine headaches. Botox carries a warning that its effects may spread from the site of injection to other parts of the body, resulting in symptoms that can be life-threatening, such as swallowing and breathing difficulties.
