According to Dr. Rohr, there's actually little scientific evidence that expired medications can be toxic or make you sick the way rotten food can. "The drug is likely to lose some potency after the expiration date, but it is not clear how much potency is lost over a certain period of time past expiration dates."
罗尔博士表示,事实上能够证明过期药物有毒或者会让你感到恶心(像腐烂食物那样)的科学证明非常少。"过期之后,药品可能会失去一定的药效,但尚不清楚过期后的某个时间段会失去多少药效。"
Just beware: Certain meds' expiration dates may matter more than others. "Insulin and nitroglycerin [which is used to treat chest pain] are known to very quickly lose their potency and therefore should not be used past expiration dates," notes Dr. Rohr. Other drugs that shouldn't be consumed after their use-by date include liquid antibiotics, which aren't as stable as their pill counterparts, and some injectables. Norepinephrine (used to treat shock and low blood pressure), for example, should be discarded if you notice discoloration, adds Dr. Rohr.
但请注意:有些药物的过期日期可能比其它药品更为重要。"众所周知,用于治疗胸痛的胰岛素和硝酸甘油会很快失去药效,所以过期后不应使用,"罗尔博士指出。其它过期后不能再使用的药品包括:液体抗生素(没有固态抗生素稳定)和一些注射剂。例如,如果去甲肾上腺素(用于治疗休克和低血压)的颜色发生变化,则应丢弃,罗尔博士补充道。
