Patients with urticaria can develop a generalized pattern of hives, which is usually accompanied by intense itching, and often does not heal on its own. If no medication is taken, the hives may subside temporarily, but they will reappear again and again, causing greater distress to the patient. Therefore, if a patient has this condition, he or she still needs immediate medication. First, he or she can take oral antihistamines, such as loratadine, cetirizine, paracetamol, and ibastine tablets, all of which are often chosen clinically and have good effects. If the patient is not able to play a better therapeutic role through oral medication, and this situation is getting more and more serious, and can even appear dyspnea, chest tightness and suffocating wheezing, to rush to the regular hospital for intravenous injection of calcium gluconate and glucocorticoid treatment.
