What information must OTC drugs include according to the Durham-Humphrey Act?

The correct information that must be included for over-the-counter (OTC) drugs according to the Durham-Humphrey Act is the active and inactive ingredients. This requirement ensures transparency for consumers, enabling them to know exactly what they are using in the medication. By informing the public of these ingredients, it allows individuals to make more informed choices, especially those who may have allergies or sensitivities to certain components.

The other choices do not accurately reflect the requirements established by the Durham-Humphrey Act for OTC drugs. Prescription requirements pertain specifically to prescription medications rather than OTC. The manufacturer's address is generally included but is not a specific requirement mandated by the Durham-Humphrey Act. Clinical trial results are typically not required for OTC drugs, as they do not undergo the same rigorous approval process as prescription medications. The focus on active and inactive ingredients aligns with the act's intent to ensure that consumers are adequately informed about the products they purchase and use.
