This medication is used to treat rheumatoid arthritis, a condition in which the body's own defense system (immune system) attacks healthy tissue. This leads to swelling in the joints, which causes pain and makes it harder to move. This medication may also be used to treat a certain other type of arthritis (juvenile idiopathic arthritis).
