Basiliximab, sold under the brand name Simulect, is a medication used to prevent rejection following a kidney transplant.[1] It is used together with ciclosporin and corticosteroids.[2] It is given by injection into a vein.[2]

Common side effects include constipation, nausea, abdominal pain, heart burn, high potassium, low potassium, headache, swelling, fever, shortness of breath, and trouble sleeping.[1] Other side effects may include infections and anaphylaxis.[1] Use in pregnancy is not recommended.[2] It is a monoclonal antibody that attaches to CD25 on T cells and thus blocks interleukin-2.[3]

Basiliximab was approved for medical use in the United States and Europe in 1998.[1][3] In the United Kingdom a typical dose costs about £840 as of 2021.[2] In the United States this amount costs about 4,100 USD.[4]

Medical uses

Basiliximab is an immunosuppressant agent used to prevent immediate transplant rejection in people who are receiving kidney transplants, in combination with other agents.[5] It has been reported that some cases of lichen planus have been successfully treated with basiliximab as an alternative therapy to cyclosporin. No short-term side effects have been reported.[6]


It is given as a dose of 20 mg within two hours of surgery followed by 20 mg 4 days later.[2]

Mechanism of action

Basiliximab competes with IL-2 to bind to the alpha chain subunit of the IL2 receptor on the surface of the activated T lymphocytes and thus prevents the receptor from signaling. This prevents T cells from replicating and also from activating B cells, which are responsible for the production of antibodies, which would bind to the transplanted organ and stimulate an immune response against the transplant.[7][8]


It is a chimeric CD25 monoclonal antibody of the IgG1 isotype.[7][8]


It is a Novartis product and was approved by the Food and Drug Administration (FDA) in 1998.[9]
