Patients w/ >25 x 109/L lymphocyte counts Administer prednisone/prednisolone 100 mg IV shortly before rituximab infusion. Previously untreated & relapsed/refractory patients Recommended dose in combination w/ chemotherapy: 375 mg/m2 administered on day 0 of the 1st treatment cycle followed by 500 mg/m2 administered on day 1 of each subsequent cycle for 6 cycles.

Contraindications
Hypersensitivity to rituximab or murine proteins. Active, severe infections. Patients in severely immunocompromised state. RA: Severe heart failure (NYHA Class IV) or severe, uncontrolled cardiac disease.
Special Precautions
Do not administer as IV push or bolus. Monitor patients at regular intervals for any new or worsening neurological symptoms or signs that may be suggestive of progressive multifocal leukoencephalopathy (PML). Permanently discontinue dosing if PML develops. Patients w/ high tumour burden or w/ high number (≥25 x 109/L) of circulating malignant cells eg, patients w/ chronic lymphocytic leukemia, who may be at higher risk of especially severe cytokine release syndrome. History of pulmonary insufficiency or those w/ pulmonary tumour infiltration. Interrupt infusion immediately & institute aggressive symptomatic treatment in patients who develop severe cytokine release syndrome. Anaphylactic & other hypersensitivity reactions. Consider withholding antihypertensive medicines 12 hr prior to infusion. Closely monitor patients w/ history of cardiac disease &/or cardiotoxic chemotherapy; those who experienced prior cardiopulmonary adverse reactions; known cardiac history, & consider risk of CV complications resulting from infusion reactions. Patients w/ neutrophils <1.5 x 109/L &/or platelet counts <75 x 109/L. Perform regular full blood counts including neutrophil & platelet counts during therapy. Active, severe infection (eg, TB, sepsis & opportunistic infections) & severely immunocompromised patients (eg, those w/ very low CD4 or CD8 levels). History of recurring or chronic infections or w/ underlying conditions which may further predispose to serious infections (eg, hypogammaglobulinaemia). Perform HBV screening (including HBsAg- & HBcAb-status) before treatment initiation. Active hepatitis B disease; monitor patients w/ positive hepatitis B serology. Permanently discontinue in case of severe skin reactions eg, toxic epidermal necrolysis (Lyell's syndrome), & Stevens-Johnson syndrome. Not recommended in methotrexate-naïve patients. Patients w/ multiple PML risk factors including underlying disease & long-term immunosuppressive therapy or chemotherapy. Measure blood neutrophils prior to each course of treatment & regularly up to 6 mth after treatment cessation. Complete vaccination at least 4 wk prior to 1st rituximab administration. Concomitant use w/ live virus vaccine & anti-rheumatic therapies other than those specified under RA indication & dosage are not recommended; DMARDs. Risk of malignancy. Women of childbearing potential should use effective contraceptive methods during & for 12 mth following therapy. Pregnancy. Should not breastfeed during therapy & for 12 mth following treatment.
