Infliximab (Inflectra)

Inflectra (infliximab) is a biologic medicine that helps the pain and swelling of arthritis. Inflectra belongs to a class of similar medications called Anti-Tumor Necrosis Factor agents.

Inflectra is used in the treatment of Rheumatoid Arthritis, Psoriatic Arthritis, Ankylosing Spondylitis, Crohn’s Disease, Ulcerative Colitis, Psoriasis, and other types of arthritis.

Inflectra works by blocking Tumor Necrosis Factor (TNF), a type of signalling protein (cytokine), that is involved in systemic inflammation.

This medication may be prescribed in combination with other rheumatology medications like methotrexate.


Inflectra is a type of medicine that is called a biosimilar. A biosimilar is a type of biologic medication that has been designed to be identical to an existing biologic medication, but is created using a different process.

Inflectra is a biosimilar of Remicade. Both medications are known by the same generic name: infliximab. Biosimilars are often cheaper than the original medication.

Taking Inflectra

Inflectra is administered by intravenous infusion at specialized clinics.

Some patients start to feel better quickly with Inflectra, but in others, it can take a little longer. It’s important for patients starting this medication to give it some time and keep receiving infusions as-prescribed.
