Women presenting to the cardiac catheterization laboratory with normal coronary arteries without significant atherosclerotic disease is a common presentation. In such patients, it is important to maintain a wide differential and consider alternate diagnoses. We present two cases of women presenting with chest pain found to have severe coronary vasospasm in the setting of recent initiation of phentermine. Phentermine may have vasospastic proprieties which are important to consider when prescribing to patients.
