What is one of the notices that must be displayed to the public in a pharmacy?

The generic substitution policy is an essential notice that must be displayed in a pharmacy as it informs patients about their rights regarding the use of generic medications. This policy outlines whether and how pharmacists can substitute prescribed brand-name drugs with their generic equivalents. It serves to promote transparency and empower patients by ensuring they are aware of the potential for cost savings and equivalent efficacy when generics are utilized.

Having this information visibly posted helps foster trust and encourages patients to discuss their medications openly with their healthcare providers. It also aligns with regulatory requirements aimed at ensuring pharmacists fulfill their obligations related to medication dispensing practices, specifically regarding the use of generics when available.

The other choices, while they may also be important for operational transparency or customer service, do not carry the same level of regulatory requirement in the context of public notices within the pharmacy setting.
