Actemra treats rheumatoid arthritis and certain types of arthritis in children. Can increase your risk for serious infections. Report signs of infections such as a fever to your doctor.

Actemra Overview


Actemra is a prescription medication used to treat rheumatoid arthritis (RA) in adults. It is also used to treat systemic juvenile idiopathic arthritis (SJIA) or polyarticular juvenile idiopathic arthritis (PJIA) in children 2 years or older.

Actemra is referred to as an interleukin-6, or IL-6, receptor inhibitor. IL-6 is a molecule produced by the body that binds to the IL-6 receptor and causes inflammation. Patients with arthritis have increased levels of IL-6 in their body. By blocking the IL-6 receptor, Actemra can decrease the symptoms of arthritis.

Actemra comes in an injectable form to be given directly into a vein (IV) by a healthcare provider. It is usually given once every 4 weeks for RA and PJIA or every 2 weeks for SJIA.

Common side effects of Actemra are cold-like symptoms, increased blood pressure, and headache.

Actemra Precautions

Actemra can cause serious infections by lowering the ability of your immune system to fight infections including tuberculosis (TB), as well as others. These are serious infections that may cause death. 

  • Your doctor should test you for TB before starting Actemra as well as monitor you closely for signs and symptoms of TB during treatment with Actemra.
You should not start taking Actemra if you have any kind of infection unless your doctor says it is okay. Before starting Actemra, tell your doctor if you think you have an infection or have symptoms of an infection such as:
  • fever, sweating, or chills

Before starting Actemra, tell your doctor if you:

  • are being treated for an infection
  • get a lot of infections or have infections that keep coming back
  • have diabetes, HIV, or a weak immune system. People with these conditions have a higher chance for infections.
  • have TB, or have been in close contact with someone with TB
  • live or have lived, or have traveled to certain parts of the country (such as the Ohio and Mississippi River valleys and the Southwest) where there is an increased chance for getting certain kinds of fungal infections (histoplasmosis, coccidiomycosis, or blastomycosis). These infections may happen or become more severe if you use Actemra. Ask your doctor, if you do not know if you have lived in an area where these infections are common.

You should not receive Actemra if your neutrophil or platelet counts are too low or your liver function tests are too high. Your doctor may stop your Actemra treatment for a period of time or change your dose of medicine if needed because of changes in these blood test results. 

You may also have changes in other laboratory tests, such as your blood cholesterol levels. Your doctor should do blood tests to check your cholesterol levels 4 to 8 weeks after you start receiving Actemra, and then every 6 months after that.

Actemra FDA Warning


Patients treated with Actemra are at increased risk for developing serious infections that may lead to hospitalization or death. Most patients who developed these infections were taking concomitant immunosuppressants such as methotrexate or corticosteroids.

If a serious infection develops, interrupt Actemra until the infection is controlled.

Reported infections include:

  • Active tuberculosis, which may present with pulmonary or extrapulmonary disease. Patients should be tested for latent tuberculosis before Actemra use and during therapy. Treatment for latent infection should be initiated prior to Actemra use.
  • Invasive fungal infections, including candidiasis, aspergillosis, and pneumocystis. Patients with invasive fungal infections may present with disseminated, rather than localized, disease.
  • Bacterial, viral and other infections due to opportunistic pathogens.

The risks and benefits of treatment with Actemra should be carefully considered prior to initiating therapy in patients with chronic or recurrent infection.

Patients should be closely monitored for the development of signs and symptoms of infection during and after treatment with Actemra, including the possible development of tuberculosis in patients who tested negative for latent tuberculosis infection prior to initiating therapy.
