Drug

Tocilizumab

Pronounced

"TOE-si-LIZ-oo-mab"

Uses

This medication is used to treat rheumatoid arthritis in adults and in children (such as systemic juvenile idiopathic arthritis-SJIA, polyarticular juvenile idiopathic arthritis-PJIA). It helps to reduce pain and swelling due to rheumatoid arthritis. Tocilizumab can also be used to treat giant cell arteritis. It helps to reduce swelling in your blood vessels so blood can flow more easily. Tocilizumab may be used to treat a reaction (Cytokine Release Syndrome-CRS) caused by certain cancer treatments. Tocilizumab is also used in combination with a corticosteroid (such as dexamethasone) to treat coronavirus disease (COVID-19) in hospitalized patients who need supplemental oxygen (including patients on a mechanical ventilator). Tocilizumab belongs to a class of drugs known as Interleukin-6 (IL-6) blockers. It works by blocking IL-6, a substance made by the body that causes swelling (inflammation).

This monograph is about the following tocilizumab products: tocilizumab, tocilizumab-aazg, and tocilizumab-bavi.

Before using tocilizumab, tell your doctor your medical history, especially of any kind of infection. During treatment, get medical help right away if you have any signs of infection (such as sore throat that doesn't go away, fever, swollen lymph nodes, chills, cough, pain when urinating).

Before starting this medication, your doctor should test you for tuberculosis (TB), except if you are using this medication to treat COVID-19.
