The treatment methods for rheumatoid arthritis mainly consist of three major categories. The first category is the use of anti-inflammatory and analgesic drugs, commonly including non-steroidal analgesics such as sustained-release diclofenac sodium tablets, and small doses of corticosteroids can also be used. For rheumatoid arthritis, the most important treatment is the choice of immunosuppressants. Commonly used immunosuppressants include methotrexate and leflunomide. After using these medications, it is necessary to regularly monitor blood routine tests and liver and kidney functions to check for possible side effects of the drugs. If the effects of the above oral medications are not satisfactory, the application of biologics can also be considered. (Specific medications should be used under the guidance of a doctor, do not self-medicate.)
