TYSABRI IV Uses and How to Use
This medication is used to treat a type of multiple sclerosis that occurs when symptoms appear in cycles of worsening and improvement (relapsing/remitting 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 and may prevent or delay disability.
Natalizumab is also used to treat a bowel condition called Crohn's disease (CD) when it is moderate to severe and/or keeps coming back. 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.
