When labeling a package item, which of the following should never be covered?

The expiration date is critical information that should always be clearly visible on any labeled package item. This date indicates the timeframe in which the medication is guaranteed to be effective and safe for use. If the expiration date is covered or obscured, it could lead to potential health risks for patients who may unknowingly use medication that is past its effective date. Maintaining the visibility of this information ensures compliance with regulatory standards and supports patient safety, as well as proper medication management practice in pharmacy settings.
