Radiocontrast-Induced Anaphylaxis

Radiocontrast-induced anaphylaxis is a severe allergic reaction that can occur after receiving substances called radiocontrast agents, which are used in medical imaging tests like CT scans. When injected, these agents enhance the visibility of internal structures. In some individuals, the body mistakenly identifies these agents as harmful, triggering an intense immune response. Symptoms can include difficulty breathing, swelling, rapid heart rate, and a drop in blood pressure. This reaction is serious and requires immediate medical attention, as it can be life-threatening. Understanding your allergy history can help healthcare providers manage this risk effectively.
