Etanercept (etanercept) — Uses, Dosage, Side Effects & Safety

Drug class: Tumor Necrosis Factor (TNF) Inhibitor; Biologic Disease-Modifying Antirheumatic Drug (bDMARD)

Overview

Etanercept is a biologic medicine used to treat autoimmune conditions such as rheumatoid arthritis, juvenile idiopathic arthritis, psoriatic arthritis, ankylosing spondylitis, and plaque psoriasis. It works by blocking tumor necrosis factor (TNF), a substance in the body that causes inflammation and can lead to joint and tissue damage. By reducing inflammation, etanercept helps relieve pain, swelling, and stiffness, and can slow the progression of joint damage. It is usually prescribed when other treatments have not worked well enough. Etanercept is given as a subcutaneous injection, typically once or twice a week, and can be used alone or in combination with other medications. Patients should be aware that etanercept can increase the risk of infections and may require regular monitoring. It is important to discuss your full medical history with your healthcare provider before starting this medication.
