What is the classification of a drug whose label misrepresents the contents or is misleading?

The classification of a drug that misrepresents its contents or is misleading falls under the category of a misbranded drug. A misbranded drug is one that has labeling or packaging issues that could deceive consumers or healthcare professionals about its strength, quality, or identity. This can include failing to provide adequate directions for use, not disclosing the proper labeling information, or providing misleading information about the product's efficacy or safety.

In contrast, an adulterated drug refers to a product that fails to meet quality standards due to contamination or incorrect manufacturing processes, thus affecting its purity or strength. A controlled drug pertains to substances that are regulated under federal or state laws due to their potential for abuse and addiction, and requires special handling and prescribing practices. A prescription drug simply refers to medications that require a doctor's authorization for dispensing, without necessarily implying any issues regarding their labeling or quality. Therefore, when a drug is misleading in its labeling, it is aptly classified as misbranded.
