Angiotensin Receptor Blockers (ARB) are used as an alternative of Angiotensin Converting Enzyme Inhibitors (ACEI) in patients where ACEIs cannot be used because of their known adverse effects, cough and angioedema. Thus ARB induced angioedema is considered to be a rare phenomenon and it is continued to be used as an alternatives of ACEIs. In this case report, we reported a case of 78-year-old gentleman who presented to emergency department with losartan, an ARB induced angioedema, who did not have history of any previous use of ACEIs. He was given steroids and antihistamine as a treatment. His angioedema resolved rapidly and he was discharged after six hours of emergency department (ED) observation with stable hemodynamically. We, the authors by reporting this case, wants to make clinicians aware ARB, however rarely, can cause angioedema, which can be life threatening if clinicians are not aware of it and diagnose and stop the offending drug promptly and treat it early.
