Skin urticaria can be treated by removing the cause of the disease, using anti-allergy drugs, and injecting drugs intramuscularly or intravenously. 1.

Therefore, we should look for the causes of urticaria, remove the causes of urticaria, and if we can’t remove the causes, we should try to minimize the factors that promote and aggravate the condition. 2. Anti-allergic drugs (1) Topical medication: mainly to symptomatic relief of itching, can be used externally with glycerite lotion, Eloxon cream, etc. to relieve itching symptoms. (2) oral drug therapy: if the itching symptoms of urticaria is more serious, often recurring, you can take antihistamines under the guidance of the doctor, such as loratadine, cetirizine and so on. 3. Intramuscular or intravenous drugs (1) Acute urticaria: If urticaria symptoms are severe, accompanied by anaphylactic shock or laryngeal edema, medical attention should be sought immediately. (2) Chronic urticaria: Possible underlying diseases should be actively sought and treated. The addition of immunologic or biologic agents, such as omalizumab, may be considered for those that are persistent. Therefore, urticaria should be removed as soon as a suspected cause is identified. In the case of more severe allergies, or even anaphylaxis, immediate medical attention should be sought.
