Uses

Natalizumab is used to treat multiple sclerosis-MS. It is not a cure for MS, but it is thought to help by preventing your immune system from attacking the nerves in your brain and spinal cord. It helps decrease the number of episodes of worsening symptoms and may prevent or delay disability. Natalizumab is also used to treat a bowel condition called Crohn's disease (CD). It is not a cure for CD, but it is thought to work by preventing your immune system from causing inflammation/swelling within your bowels. Natalizumab is a protein called a monoclonal antibody.
