What is the primary purpose of the Drug Facts Panel?

The primary purpose of the Drug Facts Panel is to summarize key product information in a clear and accessible format. This panel is designed to ensure that consumers have important information at their fingertips regarding the drug's active ingredients, purposes, uses, warnings, directions, and other necessary information to help guide their decisions about the product. The succinct nature of the Drug Facts Panel is essential for consumer safety and proper use.

In the context of the other options, informing about the price of the drug would not be appropriate since the Drug Facts Panel focuses on product information rather than pricing. While providing detailed usage instructions is part of the panel's content, its broader aim is to summarize overall key information rather than just usage. Enhancing product marketing is not a function of the Drug Facts Panel; instead, it serves to ensure transparency and safety for consumers.
