Recommended Action
Management		The increased risk of additive immunosuppression should be considered if coadministering ocrelizumab with other immunosuppressive therapy. In addition, the prolonged immunosuppressant effects and mode of action of other immunosuppressant drugs such as daclizumab, fingolimod, natalizumab, teriflunomide, or mitoxantrone should be considered prior to starting ocrelizumab therapy. Patients should be advised to notify their doctor if they develop signs or symptoms of infection, including upper or lower respiratory tract infection, skin infection, herpes related infection, or PML.
