Tysabri is a medicine for treating adults with multiple sclerosis (MS) that is not sufficiently controlled with another disease-modifying therapy or is rapidly getting worse.
Multiple sclerosis is a disease of the nerves, in which inflammation destroys the protective sheath surrounding nerves and damages the nerves themselves.
Tysabri is used in relapsing-remitting MS, a type of MS in which the patient has attacks (relapses) between periods of stable symptoms (remissions).
It contains the active substance natalizumab.
