The treatment of rheumatic fever includes general treatment, where patients are advised to rest in bed. The second is the use of antibiotics, aimed at eliminating streptococcal infections to prevent recurrent attacks of rheumatic fever. The third is anti-rheumatic treatment, with the preferred choice being non-steroidal anti-inflammatory drugs, such as sustained-release diclofenac sodium tablets. If the patient's rheumatic fever affects the heart, corticosteroid treatment is also required. In addition, to assist in the reduction of corticosteroids, some immunosuppressants need to be added, such as methotrexate and leflunomide, which help control the condition. For the treatment of complications of rheumatic disease, such as concurrent lung infection, antibiotic treatment should also be considered. (The use of medication should be under the guidance of a professional doctor.)
