The package labeling recommends the administration of a standard infusion of rituximab for all patients initiating rituximab therapy to minimize IRR. If this infusion is tolerated then subsequent infusions may be titrated up to a faster rate to decrease infusion time. Based on the manufacturer's package insert, rituximab is infused at a rate of 50 mg/hr and can be increased every 30 minutes by 50 mg/hr (maximum rate of 400 mg/hr). If a grade 3 or 4 IRR does not occur, subsequent infusions are given at a rate of 100 mg/hr and can be increased every 30 minutes by 100 mg/hr (maximum rate of 400 mg/hr). The average infusion time is estimated to be 4-6 hours for the first infusion, and 3-4 hours for subsequent infusions. Rituximab is typically given in cycles and the timing will vary depending on the indication.
