Question: what chemotherapy drugs are used for rheumatoid arthritis?
Answer: Methotrexate (Rheumatrex, Trexall). Methotrexate is the chemotherapeutic drug most widely used by rheumatologists because it is effective in treating rheumatoid arthritis and certain other rheumatic diseases (such as certain forms of vasculitis, or inflammation of blood vessels), and it is relatively safe.
