Manini, MD, from Harvard Medical School in Boston, Massachusetts, and colleagues."Cardiovascular adverse effects can occur, including hypertension, arrhythmias, prolongation of the QT interval, and angina pectoris. Dangers of over-the-counter sympathomimetic use are illustrated by the recent ban on dietary supplements containing ephedrine alkaloids by the US Food and Drug Administration because of increased risk of sudden death, acute myocardial infarction, and stroke."

Manini医师表示，Pseudoephedrine是ephedrine的镜面异构物，会产生肾上腺素的综合促效作用，一般被用来作为解充血剂；此药的副作用包含高血压、心律不整、心电图QT波间距延长及心绞痛等；最近，美国食品药物检验局规定添加剂不得含ephedrine生物碱，由此可看出仿交感神经作用的药物所潜藏的危险；这些危险包含猝死、急性心肌梗塞及中风等。
