RA has no cure, but medications can help relieve symptoms. These medications include anti-inflammatory drugs, corticosteroids, and drugs that suppress the immune system. Some of the most effective drug treatments are disease modifying anti-rheumatic drugs (DMARDs), which include TNF-alpha inhibitors. Tumor necrosis factor alpha, or TNF alpha, is a substance that occurs naturally in your body. In RA, the immune system cells that attack the joints create higher levels of TNF alpha. These high levels cause pain and swelling.
