Tysabri
Tysabri is a medication used to treat both Crohn's disease and different forms of Multiple Sclerosis (MS), such as clinically isolated syndrome, relapsing-remitting disease, and active secondary progressive disease in adults. Both autoimmune diseases are caused by immune cells attacking healthy cells in the body that are misrecognized as foreign cells that need to be destroyed. MS is an autoimmune disorder of the central nervous system characterized by inflammation, demyelination of nerve fibers in your brain and spinal cord, as well as the optic nerves, and axonal loss. MS lesions are thought to occur when immune cells cross the blood brain barrier and damage healthy tissues. As these healthy tissues such as nerves and myelin sheathing continue to be damaged, it can lead to a decrease in mobility and affect cognitive function.

How Does Tysabri Work?
TREATMENT EDUCATION
Tysabri is thought to work by helping prevent harmful immune cells from crossing into the central nervous system. Reducing the harmful immune cells in the brain may help reduce damage and inflammation caused by MS. For Crohn’s disease, the healthy cells that line the GI tract are attacked. This causes tissue inflammation, breakdown, and the formation of ulcers. Tysabri works by binding to the surface of white blood cells so they cannot pass through tissue layers and cause inflammation.
What to Expect During Your Infusion
Before your infusion, it is important to drink plenty of water and come to your appointment hydrated. Additionally, you must alert us as soon as possible to any changes in your insurance to ensure that we are still an in-network provider for your infusion therapy.
- Pure doesn’t believe in waiting rooms. You’ll be taken to your own private suite where you’ll check in and your nurse will take your vitals and complete a pre-infusion assessment.
- To begin the infusion, an IV line will be inserted into your arm or hand. The medication will be connected and the nurse will monitor the infusion carefully, especially the first few minutes, to watch for reactions or side effects and make sure you’re comfortable.
- When the infusion is complete, your IV will be removed and the nurse will apply a bandage. Your nurse will give you instructions on side effects to watch for and when to seek help. You may be asked to stay for a short observation period.
- You can resume normal activities, though you may feel tired or need to rest. Drink water and eat a light meal to help with fatigue or nausea.
