How soon must patients be notified of a pharmacy's closure via direct mail?

Patients must be notified at least 1 business day prior to the closing of a pharmacy via direct mail to ensure they have adequate time to make necessary arrangements for their medications. This notification requirement is in place to uphold patient care standards and ensure continuity of medication access.

Notifying patients in advance helps them prepare for potential disruptions in their pharmaceutical care, allowing them the opportunity to transfer prescriptions to another pharmacy if needed. The requirement emphasizes the importance of clear communication between pharmacies and their patients regarding significant changes that may affect their health and well-being.

The other options do not align with this requirement, as they either suggest a time frame that is too lengthy or conditional on previous interactions, which could lead to gaps in care for patients who may not be informed promptly.
