Symptom relievers include: small doses of hormones, anti-inflammatory and painkillers. They are applied for a short period of time and are reduced or stopped under the guidance of a doctor when the disease improves. The drugs for treating the disease are divided into oral and injectable. Oral ones include methotrexate, leflunomide, hydroxychloroquine, salazosulfamethoxazole, and rhodopsin. The cost is relatively low. Injectable drugs are biologic agents with the best efficacy and high cost, including Classic, Ixep, Enzyme, and Xumile. Classic is injected intravenously, 6-8 times a year. The rest are subcutaneous injections, with Iscap and Enry being given once or twice a week and Xumel once every 2 weeks.
