Trexall (methotrexate) is an antimetabolite and antifolate drug used in both the treatment of cancer and certain autoimmune diseases. Its use in lupus has not been thoroughly tested, but it has been shown to improve joint pain and stiffness in lupus patients who have arthritis. It is only modestly effective for organ-threatening lupus.
Trexall works by slowing the growth rate of certain cells.
