Tocilizumab

Generic Name: tocilizumab (TOE-si-LIZ-ue-mab)
Brand Name: Actemra

Patients who use tocilizumab have an increased risk of developing serious and sometimes fatal infections, including tuberculosis (TB), fungal infection, and other types of infection. Most patients who developed these infections were also taking medicine that suppressed their immune system (eg, corticosteroids, methotrexate).

Patients should receive a TB skin test before using tocilizumab. Patients who test positive for TB should begin treatment for TB before starting tocilizumab. All patients should also be monitored for signs of TB while using tocilizumab even if their TB test is negative.

Contact your doctor immediately if you develop signs of TB or any other type of infection (eg, persistent cough; muscle weakness; unexplained weight loss; fever, chills, or persistent sore throat; shortness of breath; unusual tiredness; warm, red, or painful skin or sores; increased or painful urination; severe or persistent diarrhea or stomach pain; blood in the mucus).


Tocilizumab is used for:

Treating moderate to severe rheumatoid arthritis (RA) in certain patients. It may be used alone or in combination with other medicine. It may also be used for other conditions as determined by your doctor.

Tocilizumab is an interleukin-6 (IL-6) receptor blocker. It works by blocking a substance (IL-6) in the body that contributes to inflammation.

Do NOT use tocilizumab if:

  • you are allergic to any ingredient in tocilizumab
  • you have a severe infection (eg, sepsis) or any other active infection
  • you have liver problems
  • you are using abatacept, adalimumab, anakinra, canakinumab, certolizumab, etanercept, golimumab, infliximab, rilonacept, rituximab, or tofacitinib

Contact your doctor or health care provider right away if any of these apply to you.
