Rheumatoid arthritis is a chronic disease. Like hypertension and diabetes, rheumatoid arthritis is a chronic autoimmune disease that requires long-term medication to achieve clinical remission, so patients with rheumatoid arthritis can apply for chronic disease health insurance. After applying for chronic disease health insurance, some patients can also be reimbursed in outpatient settings. For patients with rheumatoid arthritis, once diagnosed, it is important to add drugs that control the disease as soon as possible and can slow down the progression of the patient’s joints, most commonly methotrexate, leflunomide and other immunosuppressive drugs. However, in the process of using these drugs, it is necessary to regularly monitor such indicators as blood routine, liver and kidney function to monitor the side effects of the drugs.
