The treatment of dry syndrome includes symptomatic treatment, mainly for symptoms such as dry mouth, dry eyes, joint pain, and low blood potassium, such as using artificial tears, drinking more water, and taking oral potassium supplements. After dry syndrome involves other organs, comprehensive treatment is needed, such as interstitial pneumonia, hormone or immunosuppressant is needed. Immunosuppressants are preferred to cyclosporine, and methotrexate must be used with caution or disabled with special emphasis on interstitial lung lesions. If there is myositis, immunosuppressants, mycophenolate and cyclophosphamide are preferred, and hormone therapy can also be added. Combined autoimmune hepatitis is treated with hormones and ursodeoxycholic acid. Hematologic involvement and thrombocytopenia are treated with hormones, cyclosporine and other immunosuppressive agents. All in all, hormone and immunosuppressive therapy is needed under the guidance of a doctor.
