Final answer:
The expiration date used to label a prescription is usually one year from the date dispensed or the manufacturer's expiration.
Step-by-step explanation:
The expiration date used to label a prescription is one year from the date dispensed or the manufacturer's expiration.
This means that the prescription is valid for one year from the date it was dispensed, or until the manufacturer's expiration date, whichever comes first.
For example, if a prescription is dispensed on January 1, 2022, it would expire on January 1, 2023, or the manufacturer's expiration date, if that date is earlier.
