Drug

Certolizumab Pegol

Pronounced

"SER-toe-LIZ-oo-mab"

Uses

This medication is used to reduce pain and swelling due to certain inflammatory conditions (such as rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis, plaque psoriasis, polyarticular juvenile idiopathic arthritis). Some brands may also be used to treat a certain type of spine condition (axial spondyloarthritis) or a certain bowel condition (Crohn's disease). Certolizumab belongs to a class of drugs known as tumor necrosis factor (TNF) blockers. It works by blocking TNF, a substance made by the body that causes inflammation.

Warning

This medication can decrease your body's ability to fight an infection. This effect can lead to very serious (possibly fatal) infections (such as fungal infections, bacterial infections including tuberculosis). You should have a tuberculosis (TB) skin test before and during treatment with this medication. Also tell your doctor your medical history, especially of past/recent/current infections. You should also tell your doctor if you have lived or traveled in areas where certain fungal infections (such as coccidioidomycosis, histoplasmosis) are common or if you have been near someone with tuberculosis. Tell your doctor right away if you develop signs of an infection while using this drug, such as sore throat or cough that doesn't go away, fever, chills, night sweats, painful/frequent urination, unusual vaginal discharge, white patches in the mouth (oral thrush).

If you are diagnosed with TB, you must first be treated for it before you start certolizumab to prevent a serious TB infection.

Though it is very unlikely to happen, there is a risk (especially in children/teens/young adults) of developing cancer (such as lymphoma, skin) due to this medication or due to your medical condition. Discuss the risks and benefits of treatment with your doctor. Tell your doctor right away if you develop symptoms such as fever that doesn't go away, unusual lumps/growths, skin changes, swollen glands, swollen or painful abdomen, unexplained weight loss, or night sweats.
