四分律行事鈔資持記 3.479

七日更加犯捨一提，服用一吉，故有五罪。《戒疏》止生四罪，彼云有人立五，謂服此藥今解，不然，服則有罪，不服無過；不同上四不服罪生。故知今鈔猶存昔解。

For seven-day [medicine], further adding one pāyattika for the offense of forfeiture and one duṣkṛta for consuming it, there are thus five offenses. The Precept Commentary only generates four offenses; it says that someone established five, referring to consuming this medicine. The present explanation is not so: if consumed there is an offense, but if not consumed there is no fault; it is unlike the above four where offenses arise without consumption. Thus we know that the present Transactions Manual still retains the old explanation.
