Hi, Doctor My mother who is 61 years old is suffering from chronic rhymatoid arthritis daiagnosed about 7 years ago. She was treated wiht mutiple medications , but currently she is on Folvite, Folitrex ( methotrexate ), and SAZO , and about 2 to 4 tablets of chrocin 650 mg daily, but still now her problem has increased to the point where she is finding difficulty to walk few steps. I think she is allergic to sulfa medications. Can u please suggest any other medication that does not contain sulfa drug.
