Golimumab is a biologic medicine used for inflammatory autoimmune diseases such as rheumatoid arthritis, psoriatic arthritis, axial spondyloarthritis and ulcerative colitis. It is used when inflammation causes pain, stiffness, joint damage risk or persistent bowel symptoms.
Golimumab blocks tumour necrosis factor alpha, a protein involved in the inflammatory process. By reducing this signal, it may lessen pain, swelling, stiffness and disease activity. The effect may take time, so the doctor will reassess whether the treatment is working well enough. It may be combined with methotrexate or other medicines according to the treatment plan.
The medicine is given as a subcutaneous injection, usually monthly, or intravenously in certain situations, depending on the prescribed formulation. Before starting, patients need screening for tuberculosis, hepatitis B and other relevant infections. Do not receive live vaccines unless your doctor agrees. Report fever, repeated infections, persistent cough, non-healing wounds or planned surgery.
Common side effects include upper respiratory tract infections, sore throat, blocked or runny nose and injection-site reactions. Serious but less common problems include severe infections, reactivation of tuberculosis or hepatitis B, allergic reactions, worsening heart failure, neurological disorders or certain cancers. Seek prompt help for high fever, breathing difficulty, jaundice or sudden weakness.
