Risky idea: If you stop your infusions abruptly, and do not replace with a potent ms agent such as gilenya, you will be at very high risk for a relapse, and a substantial rebound of the disease, at about 3 months. If you do have a positive anti-jcv antibody test, you and your doctor might decide to stop tysabri (natalizumab) by 18-24 months, but you need to start a new medication. Discuss with your neurologist.
