四分律比丘含注戒本 2.365

2.365

舉宿而食，咽咽墮。「非時」「七日」過限，亦墮。盡形壽藥，無病因緣而服者，吉羅。

Storing it overnight and eating it, with each swallow one commits a prāyaścittika. If 'untimely' medicine or 'seven-day' medicine exceeds the time limit, one also commits a prāyaścittika. If one takes lifelong medicine without the cause of illness, it is a duṣkṛta.
