I am currently on Stelara. However, my GI/rheum docs want to switch me to Humira because they think it helps better with the joints (synovitis). My GI symptoms are controlled on stelara. The GI doc wants to start me on Humira PLUS methotrexate to prevent antibody formation. However, it seems that practice is falling out of favor? Is methotrexate really necessary when starting humira????
