Is the inclusion of questions and a telephone number in the Drug Facts Panel mandatory for OTC drugs?

The inclusion of questions and a telephone number in the Drug Facts Panel for OTC drugs is indeed optional. According to the regulations set forth by the FDA, while manufacturers are encouraged to include a telephone number for consumers to reach out with questions or to report adverse effects, it is not a mandatory requirement. This guideline allows for some flexibility, ensuring that consumers have access to a point of contact for additional information, but does not impose a strict obligation on manufacturers. Therefore, it's accurate to say that including this information in the Drug Facts Panel is not required and falls under the category of optional content. This understanding is crucial for compliance with labeling regulations for over-the-counter medications.
