Michelle from Sunny Island Beach asks: I have RA and Lupus and have been taking Methotrexate and Plaquenil in combination with rituximab. My insurance will no longer cover Rituxan but it will cover Humira or Enbrel. Is it possible to replace rituximab with a TNF blocker? My doctor told me I can’t “step down” from rituximab to another medication.
For rheumatoid arthritis, there is no clear evidence to suggest any biologic when used under optimal conditions is better than another. A patient would never be stepping down between different biologics, just switching. However, patients with lupus do need to be cautious with TNF blockers as they can exacerbate their disease. Rituximab is considered safer for lupus patients.
