You may be wondering what Actemra is, how it works, and what the side effects are. In this article, we will break down everything you need to know about Actemra.
What Is Actemra?
Actemra (tocilizumab) is a prescription drug used to treat several autoimmune and inflammatory diseases. These diseases include rheumatoid arthritis (RA), giant cell arteritis, a type of lung disease, certain types of arthritis in children, and COVID-19. Actemra is also used to manage cytokine release syndrome, a severe reaction to certain cancer treatments.
Actemra was developed by Genentech, and the FDA first approved it on January 8, 2010 [1]. It belongs to a class of drugs known as interleukin-6 (IL-6) receptor antagonists, and it works by blocking a protein in the body called IL-6, which causes inflammation in autoimmune diseases [2].
Like all medications, Actemra can also cause side effects. Therefore, discussing the risks and benefits of the treatment with your provider is crucial.
What Is Actemra Used To Treat?
Actemra is FDA-approved to treat the following conditions [2]:
Rheumatoid Arthritis (RA): RA is a long-term inflammatory disease that primarily affects the joints. It causes symptoms like joint pain, swelling, and stiffness. Actemra is used to treat moderate to severe rheumatoid arthritis in adults who have not responded well to other treatments.
Giant Cell Arteritis (GCA): This is an inflammatory disease that affects the large blood vessels in the head. Actemra is used to treat GCA. It can help reduce inflammation and prevent complications like vision loss.
Systemic Sclerosis-Associated Interstitial Lung Disease (SSc-ILD): This is a rare and severe condition where the lungs get scarred, making it hard to breathe. Actemra is used to slow the progression of this lung disease.
Polyarticular Juvenile Idiopathic Arthritis (PJIA): This is a type of arthritis that affects five or more joints in children. Actemra is indicated to treat children aged 2 years or older with PJIA.
Systemic Juvenile Idiopathic Arthritis (SJIA): SJIA is a severe form of juvenile arthritis that causes inflammation in one or more joints and affects internal organs. Actemra is indicated to treat children aged 2 years or older with SJIA.
Cytokine Release Syndrome (CRS): CRS is a serious and life-threatening reaction caused by certain cancer treatments like CAR T-cell therapy. Actemra is used to treat adults and children aged 2 years or older with CRS. It can manage CRS by reducing inflammation.
COVID-19: Actemra was granted emergency use authorization by the FDA for treating hospitalized adults with severe COVID-19. It is used for COVID-19 patients who are already taking corticosteroids and need oxygen support.
How Does Actemra Work?
In autoimmune diseases such as rheumatoid arthritis, your immune system becomes overactive and mistakenly attacks your own body. This action causes inflammation and pain, especially in the joints. This happens because a protein in your body called interleukin-6 (IL-6) signals your immune system to create inflammation.
Actemra works by blocking the IL-6 protein from attaching to its receptor on the surface of cells [2]. By doing this, Actemra reduces the inflammation that causes the symptoms of various autoimmune and inflammatory diseases.
Side Effects
Like all medications, Actemra can cause side effects. Below are some of the side effects of Actemra [3]:
