Anyone on Humira and sulfasalazine? I've been on Humira since May 2013 and just started sulfasalazine for psoriatic arthritis. Blood work was run and Humira is doing what it is supposed to do inside. Yay! I've had horrible joint pain/flu like symptoms for months. Rheum dr. put me on sulfasalazine. It seems to be working. Just wondered what others experiences have been with these two meds together. I'm sorry if this is not the correct forum to post in.
