按医嘱;按处方指示(尤指药物的用法用量、频率和疗程要严格遵照医生或药品标签的说明来执行)。在非医疗语境中也可引申为“按规定/按要求”。
/æz prɪˈskraɪbd/
Take this medicine twice a day, as prescribed.
按医嘱每天服用两次这种药。
If symptoms persist even when the antibiotics are taken exactly as prescribed, you should contact your doctor rather than increasing the dose on your own.
如果即使严格按医嘱服用抗生素症状仍持续,你也应联系医生,而不是自行加大剂量。
prescribe 源自拉丁语 praescribere(prae- “在前” + scribere “写”),原义有“预先写下/规定”的意思;在现代英语中常指医生“开处方、规定用法”。as prescribed 字面即“如同所规定的那样”,因此固定用来表示“按处方/按医嘱”。
