Safety and efficacy not established
Lactation. Type I hypersensitivity or anaphylactic reactions to murine proteins or component of the formulation.
Rituximab is a chimeric monoclonal antibody to CD20 antigen which regulates cell cycle initiation. It binds to the antigen on the cell surface, activating complement-dependent B-cell cytotoxicity; and to human Fc receptors, mediating cell killing through an antibody-dependent cellular toxicity.
Extensive tumor burden, pulmonary tumor infiltration or pulmonary insufficiency; history of cardiac disease; effective contraception during and up to 12 mth after treatment; pregnancy. Monitor CBC and platelet counts regularly. Premedication with analgesics, antihistamines and corticosteroids may be recommended.
