Patient Education

RimabotulinumtoxinB Injection


RimabotulinumtoxinB injection is used to relieve the symptoms of cervical dystonia (spasmodic torticollis; uncontrollable tightening of the neck muscles that may cause neck pain and abnormal head positions). RimabotulinumtoxinB injection is also used to treat chronic sialorrhea (ongoing drooling or excessive salivation). RimabotulinumtoxinB injection is in a class of medications called neurotoxins. When rimabotulinumtoxinB injection is injected into a muscle, it works by blocking the nerve signals that cause uncontrollable tightening and movement of the muscles. When rimabotulinumtoxinB is injected into saliva glands, it works by blocking the nerve signals that cause excessive saliva production.
