The treatment of drug allergy requires promptness and caution. Once a drug allergy is identified, the suspected allergenic medication should be discontinued immediately, and medical attention should be sought as soon as possible. The treatment principles include discontinuation of the allergenic drug, promotion of drug excretion, anti-allergic therapy, and symptomatic treatment. For patients with mild symptoms, antihistamines such as loratadine or cetirizine may be appropriately selected to alleviate symptoms. For more severe cases, a combination of various anti-allergic medications might be necessary, such as intravenous administration of vitamin C, calcium gluconate, or sodium thiosulfate. In severe cases, such as anaphylactic shock, immediate emergency treatment is required, including administration of adrenaline and possibly intravenous corticosteroids. Additionally, the patient's vital signs should be closely monitored to prevent complications. In summary, the treatment of drug allergy should be tailored according to the severity of the condition to ensure patient safety.
