Etanercept (Brenzys)

Brenzys (etanercept) is a biologic medicine that helps the pain and swelling of arthritis. It is used in the treatment of Rheumatoid Arthritis, Psoriatic Arthritis, Ankylosing Spondylitis, and other types of arthritis.

Brenzys works by blocking a signalling protein (or cytokine) called Tumor Necrosis Factor (TNF) that is involved in systemic inflammation. Brenzys belongs to a class of similar medications called Anti-Tumor Necrosis Factor agents.


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

Brenzys is a biosimilar of Enbrel. Both medications are known by the same generic name: etanercept. Biosimilars are often cheaper than the original medication.

Taking Brenzys

Brenzys is available as a subcutaneous (under the skin) injection that can be taken at home.
