Originally methotrexate was given in massive doses in chemotherapy in the treatment of cancer. However it was found a result those relatively small doses of methotrexate can cause enough of a change in the immune system to stop it from causing the inflammation that is Rheumatoid Arthritis. Methotrexate is now seen as the gold standard in the treatment of Rheumatoid arthritis. It has to be administered with care though along wit folic acid supplements because it depletes folic acid and can bring about kidney toxicity
