Acute coronary syndrome (ACS) is caused by a thrombotic condition in the coronary arteries. It may present as acute ST-segment elevation myocardial infarction (STEMI) or non–ST-segment elevation acute coronary syndrome (NSTEACS). Dual antiplatelet therapy (DAPT) is the primary strategy to reduce mortality and prevent future thrombosis in patients with acute STEMI. Nonetheless, allergy to these agents remains a clinical challenge during treatment. We describe a 68-year-old man with inferolateral STEMI who developed an allergic reaction to acetylsalicylic acid and clopidogrel after administration of a loading dose of DAPT. The patient was treated with fibrinolysis, which was considered successful. Angiography was not performed because of the patient’s antiplatelet allergy. The DAPT allergy was successfully managed by reintroducing and rapidly desensitizing DAPT through the ADAPTED registry protocol. Alternative strategies are available when desensitization is not feasible.
