Botulinum toxin is a nerve impluse "blocker." It binds to nerve endings and prevents the release of chemical transmitters that activate muscles. These chemicals carry the "message" from the brain that causes a muscle to contract; if the message is blocked, the muscle doesn't spasm. Botulinum toxin usually takes full effect within 1 to 2 weeks. However, the nerve endings usually grow new connections to the muscles at sites that have been exposed to botulinum toxin. Therefore, treatment must be repeated as necessary. |
