舌下片正確用法：含於舌下溶解，不可吞服。若胸痛未緩解，每 5 分鐘含服一片，最多 3 片。若含服第一片後 5 分鐘疼痛未緩解或加劇，應立即呼叫急救系統（911/119），而非等吃完三片再報。藥物具光敏感性，需避光保存。
Nitroglycerin tablets should be placed under the tongue to dissolve for rapid absorption, as chewing or swallowing significantly reduces efficacy. The medication must be stored in a dark, airtight container to protect it from degradation by light and moisture, and patients should be instructed on the proper dosing schedule during an angina attack.
✦ 台美臨床差異
美國 EMT 體系發達，社區衛教常強調早期啟動 911；台灣民眾對於含服藥物後的緊急後送啟動時機常有猶豫。
