Natalizumab injection is used to treat patients with relapsing forms of multiple sclerosis (MS). Natalizumab will not cure MS, but it may slow some of the disabling effects and decrease the number of flare-ups (relapses) of the disease.

Natalizumab injection is also used to treat moderate to severely active Crohn's disease (CD) when other medicines or treatments did not work well. Natalizumab will not cure CD, but may prevent it from occurring again.

Natalizumab is available only under a restricted distribution program called the TOUCH® Prescribing program.
