Tysabri and Multiple Sclerosis

A healthcare provider may prescribe
 Tysabri® (natalizumab) to treat multiple sclerosis (MS). This medication can help slow down disability and prevent relapses (times when symptoms worsen) in people with multiple sclerosis (MS).
 
The dosage of Tysabri is the same for everyone, regardless of age or weight. Your healthcare provider will administer the intravenous (IV) infusion once every four weeks.
 
Although Tysabri can be an effective treatment for relieving MS symptoms, it is not a cure for this condition. You should only receive Tysabri if other MS treatments are unsuccessful.
