Dosage
The initial dose of 600 mg is administered as two separate intravenous infusions; first a 300 mg infusion followed by a second 300 mg infusion that is administered 2 weeks later.
After the initial dose, subsequent doses of ocrelizumab are administered as a single intravenous infusion of 600 mg every 6 months (Table 1). The first of the subsequent doses of 600 mg should be administered 6 months after the first infusion of the initial dose. A minimum interval of 5 months should be respected between each dose of ocrelizumab.

Management of IRRs during and after infusion
Patients should be monitored during the infusion and for at least 1 hour after the infusion is completed.
During infusion
In the event of IRRs during infusion, consult the following adjustments.
Life-threatening IRRs
If there are signs of a potentially life-threatening or incapacitating IRR during an infusion, such as acute hypersensitivity or acute respiratory distress syndrome, the infusion should be stopped immediately and the patient should receive appropriate treatment. In these patients, the infusion should be stopped permanently (see section 4.3).
Severe IRRs
If a patient experiences a severe IRR (such as dyspnea) or a combination of symptoms of flushing, fever, and sore throat, the infusion should be stopped immediately and the patient should receive symptomatic treatment. The infusion should only be restarted after the resolution of all symptoms. The initial infusion rate at the time of restarting should be half the infusion rate at the time of the reaction. No adjustment of the infusion is required for subsequent infusions, unless the patient experiences an IRR.
Mild to moderate IRRs
If a patient experiences a mild to moderate IRR (e.g. headache), the infusion rate should be reduced to half the infusion rate at the time of the reaction. This reduced rate should be maintained for at least 30 minutes. If tolerated, the infusion rate may be increased according to the patient's initial infusion rate. No adjustment of the infusion is required for subsequent infusions, unless the patient experiences an IRR.
?Patients who experience severe respiratory symptoms, such as bronchospasm or exacerbation of asthma, should stop the infusion immediately and permanently. After administering symptomatic treatment, the patient should be monitored until the respiratory symptoms have resolved, as initial improvement of clinical symptoms may be followed by deterioration.
?Hypersensitivity may be clinically indistinguishable from an IRR in terms of symptoms. If hypersensitivity is suspected during infusion, the infusion should be stopped immediately and permanently.
