Remicade is an FDA (U.S. Food and Drug Administration) approved medication manufactured by Janssen Biotech, Inc. It is classed as a tumor necrosis factor-alpha inhibitor and is used to treat inflammatory autoimmune diseases. While Remicade is generally well tolerated, there are some potential side effects that people should be aware of. The most common side effects of Remicade include an increased risk of infections. Less common, but more serious side effects, can include kidney or liver injury.

What is Remicade (infliximab)?

Remicade contains infliximab as the active ingredient. It is a biologic drug made from living organisms. Remicade is used alone or in combination with methotrexate to treat inflammatory autoimmune diseases such as rheumatoid arthritis, plaque psoriasis, psoriatic arthritis, and ankylosing spondylitis. It can also be used to treat similar inflammatory conditions, such as Crohn’s disease, and ulcerative colitis.

Infliximab reduces the inflammation caused by some autoimmune and inflammatory diseases. Inflammation is a natural process your immune system uses to clear itself of infections. When your immune system detects infections, or when it accidentally attacks normal cells in your body, it releases a substance called TNF. TNF travels to the site of infection where it triggers inflammation.

Infliximab blocks this process. It binds with TNF, stopping it from working, and reducing your levels of inflammation. This can ease the symptoms of your disease, limit the damage they can cause, and reduce the severity and frequency of flare-ups.

Always check with your doctor or pharmacist before taking any medication, including Remicade, to make sure it is safe for you.
