— Explanation · 中文詳解 —
硝化甘油貼片應貼在乾淨、無毛髮的皮膚區域以利吸收。為了避免藥物耐受性（Tolerance），通常建議會有 8-12 小時的「無藥期」。必須移除舊貼片再貼上新貼片，否則會導致藥物劑量過載。頭痛是血管擴張的常見副作用，通常可耐受，不需立即停藥。
A nitroglycerin patch should be applied to clean, hairless skin to optimize absorption. To prevent drug tolerance, a 'nitrate-free interval' of 8-12 hours is generally recommended. The old patch must be removed before applying a new one to avoid dose overload. Headache is a common side effect of vasodilation and is usually tolerable; the medication should not be discontinued without consulting a provider.
