A male patient with a medical history of bronchial asthma, allergic rhinitis, and atopic dermatitis developed immediate-type hypersensitivity reactions while being treated with cefcapene-pivoxil, heparinoid, and olopatadine. The patient had previously experienced recurrent idiopathic urticaria and developed urticaria after using heparinoid lotion. He also experienced anaphylaxis after taking olopatadine granules. A prick test revealed a positive reaction to polyethylene glycol, which is present in both the heparinoid and olopatadine. After receiving cefcapene-pivoxil, the patient developed skin and respiratory symptoms. The diagnosis of immediate-type hypersensitivity reaction was made, and the patient was treated with epinephrine and discharged with improvement. [Extracted from the article]
