The root cause of persistent eczema is mainly from life and living conditioning. If there are medical conditions, such as kidney failure, digestive system diseases, or endocrine system diseases, the disease needs to be treated in internal medicine first, followed by eczema conditioning. It is also necessary to reduce the occurrence of excessive exertion due to the stress of life and the resulting insomnia. Avoid prolonged exposure to strong sunlight, contact with animal fur and chemical fiber components, scrubbing and scrubbing with salt water, alcohol, vinegar, etc. Clinical treatment may include oral antihistamines such as chlorpheniramine maleate tablets, olopatadine hydrochloride tablets or levocetirizine hydrochloride tablets, and topical medications such as glucocorticoid ointment, halomethasone ointment or hydrocortisone butyrate ointment.
