In the vast majority of patients with clinical urticaria, the condition does not recur within a short period of time. For patients with mild urticaria, after taking loratadine for 3-5 days, the urticaria can be completely controlled and no further attacks will occur. Patients can take loratadine, cetirizine and paracetamol, which are antihistamines, in clinical practice. However, if the patient has recurrent hives, the time taken for loratadine will be longer, and some patients will experience a reoccurrence once the medication is stopped. For such patients, it is not recommended to stop the antihistamines easily, and it is recommended to treat them with oral and topical Chinese medicine at the same time.
