Natalizumab is used to prevent episodes of symptoms and slow the worsening of disability in adults who have relapsing forms of multiple sclerosis (MS; a disease in which the nerves do not function properly and people may experience weakness, numbness, loss of muscle coordination, and problems with vision, speech, and bladder control), including: clinically isolated syndrome (CIS; first nerve symptom episode that lasts at least 24 hours), relapsing-remitting disease (course of disease where symptoms flare up from time to time), active secondary progressive disease (later stage of disease with continuous worsening of symptoms.) Natalizumab is also used to treat and prevent episodes of symptoms in adults who have Crohn's disease (a condition in which the body attacks the lining of the digestive tract, causing pain, diarrhea, weight loss, and fever) who have not been helped by other medications or who cannot take other medications. Natalizumab is in a class of medications called monoclonal antibodies. It works by stopping certain cells of the immune system from reaching the brain and spinal cord or digestive tract and causing damage.
