Infliximab (Renflexis)

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

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

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


Renflexis 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.

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

Taking Renflexis

Renflexis is administered by intravenous infusion at specialized clinics.

Some patients start to feel better quickly with Renflexis, 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 by their doctor.
