A prescription calls for one capsule of a medication to be administered PO ac.

The abbreviation"PO"means"by mouth" (per os).

The abbreviation"ac"stands for"before meals" (ante cibum).

The phrase"daily for 14 days"indicates that the patient should take the medication once a day for a total of 14 days.

Thus, the correct label instructions should be:"Take one capsule by mouth before a meal once daily for 14 days."
