Etanercept is widely used in the treatment of autoimmune diseases, particularly rheumatoid arthritis. It works by inhibiting tumor necrosis factor (TNF), a substance in the body that causes inflammation. By blocking TNF, etanercept helps reduce inflammation, pain, and swelling in joints, improving mobility and quality of life for patients.

In addition to rheumatoid arthritis, etanercept is also effective in managing other conditions such as psoriatic arthritis, ankylosing spondylitis, and plaque psoriasis. It is often prescribed when other treatments have not provided sufficient relief. The medication is typically administered via subcutaneous injection, allowing for convenient at-home use.

Etanercept has shown significant benefits in slowing the progression of joint damage in rheumatoid arthritis patients, making it a crucial component of long-term management strategies. It is also used in pediatric patients with juvenile idiopathic arthritis, offering relief and improved function in younger populations.

While etanercept is highly effective, it is important for patients to be monitored for potential side effects, including an increased risk of infections due to its immune-suppressing properties. Overall, etanercept plays a vital role in the therapeutic landscape for chronic inflammatory and autoimmune conditions.
