Urticaria is an allergic skin disease with the main clinical manifestation of repeated erythema and wind-bursts around the body, accompanied by significant itching. When suffering from urticaria, you should first avoid eating spicy and irritating foods, such as beef and mutton, seafood, and spicy hotpot. For treatment, you can take oral antihistamines, such as loratadine tablets, levocetirizine hydrochloride tablets or olopatadine hydrochloride tablets. However, it is recommended to go to a regular hospital and give reasonable treatment after a clear diagnosis by a clinician, and if necessary, several drugs can be combined.
