What type of violation occurs when a drug does not bear its generic name in a type size less than half that of the trade name?

The situation described pertains to labeling requirements for pharmaceuticals, particularly the necessity for proper representation of both the trade name and the generic name. If a drug's generic name is not displayed in a type size that is less than half that of the trade name, it constitutes a violation related to misbranding.

Misbranding involves misleading information on the label or failure to conform to federal labeling requirements, which stipulate that the generic name must be clearly and prominently displayed, but not as prominently as the trade name. The purpose of these regulations is to ensure that healthcare providers and patients are adequately informed about the medication they are receiving and can make informed choices.

In this context, misbranding specifically addresses the issue of misleading or improper labeling which could lead to confusion about the identity or use of the drug. Failure to meet these labeling requirements does not necessarily compromise the drug's physical integrity—thus it would not fall under adulteration—nor does it involve the integrity of the drug itself being falsified as seen in counterfeit situations. Over-labeling typically refers to excess information rather than information that is improperly formatted or presented in a misleading manner.
