Hi lobdell! I do know that at least a few of our members take (or have taken) both Leflunomide and Methotrexate to treat their RA. However, I do not know that their particular treatment plans entailed. Hopefully, some of them will chime in here! I hope this treatment plan is working well for you, if you are on this particular protocol. Best, Erin, RheumatoidArthritis.net Team Member.
