What Brenzys is used for
Brenzys is used in adults for the treatment of:
non-radiographic axial spondyloarthritis (nr-AxSpA)
Tumour necrosis factor (TNF) is a naturally occurring chemical messenger in your bloodstream.
TNF plays a role in causing pain and swelling in the joints. Brenzys is a biotechnology-derived
protein that works by binding to TNF and preventing it from acting. This reduces the
pain and swelling of rheumatoid arthritis and psoriasis, helps to treat the skin lesions
of psoriasis and psoriatic arthritis, and improves the condition of patients with
ankylosing spondylitis and nr-AxSpA.
Your doctor may have prescribed Brenzys for another reason. Ask your doctor if you
have any questions about why Brenzys has been prescribed for you.
This medicine is available only with a doctor's prescription.
Brenzys is not addictive.
Brenzys is not indicated for use in children less than 18 years of age. Other etanercept
products are available for use in children.

other parts of the body, rash, itching, hives or flushed red skin, dizziness or light-headedness.
You have, or are at risk of developing, sepsis (blood poisoning), or long-term or

to fight a serious infection.
