Do unit-of-use products such as inhalers require a product identification label?

Unit-of-use products, such as inhalers, do not require a product identification label. This is because these products are typically packaged and labeled in a way that aligns with their specific use, allowing patients to identify and use them without the need for an additional product identification label. The design and packaging of inhalers often provide relevant usage information directly on the product, fulfilling regulatory and safety standards without necessitating a separate identification label.

The other choices suggest varying levels of requirements for labeling. The incorrect options imply that unit-of-use products either always or only under certain circumstances need separate identification labels, which does not align with the established regulations regarding these types of products. Many inhalers and similar medications are provided to patients in their final dosage form, meaning they already fulfill the labeling requirements inherent to their packaging.
