Health guidance for patients with SLE: 1. Avoid sunlight exposure, quit smoking, avoid cold, exertion, mental trauma and malnutrition, and pay attention to keeping warm in winter to avoid frostbite. 2. Avoid drugs that can induce lupus and aggravate the disease such as penicillin, streptomycin, tetracycline, sulfonamide, chloramphenicol, pautazone, birth control pills, reserpine, vaccines, hydrazinoprazine, phenytoin sodium, isoniazid, etc. Vaccination is not recommended during the active period. Avoid foods that may cause photoallergy such as celery, figs, mushrooms and alfalfa. Three meals should be nutritious and balanced, rich in vitamins. Pregnancy can be avoided in patients with active lupus because pregnancy and postpartum can aggravate the disease, and SLE patients are prone to miscarriage in the first trimester of pregnancy, with high rates of preterm birth and stillbirth. It must be followed up regularly and observed closely. Because dexamethasone cannot be oxidatively inactivated by placental enzymes, so if oral hormones are needed during pregnancy to oral prednisone, dexamethasone, salicylates, non-steroidal anti-inflammatory drugs, antimalarials and cytotoxic drugs (cyclophosphamide, azathioprine, nitrogen mesylate, etc.) should not be used during pregnancy have adverse effects on the fetus, and their application is contraindicated in pregnant women. X-rays should be avoided during pregnancy. 5. Hormone is an important drug for the treatment of SLE, because lupus patients cannot get sunlight, so calcium supplements and kidney tonic herbal medicines are appropriate during taking hormone, and the amount of hormone should be gradually reduced after the condition is stabilized for a certain period of hormone treatment, but the amount must be gradually reduced under the guidance of doctors, and should never be reduced or stopped by oneself, as many relapses and deterioration of SLE are caused by this.
