What minimum information must be included on an OTC drug label?

The essential components that must be included on an over-the-counter (OTC) drug label are the active ingredients, warnings, and directions for use. The inclusion of active ingredients provides consumers with crucial information regarding what the product contains and its therapeutic effects, which helps users identify the drug's intended purpose. Warnings are critical for informing consumers about possible side effects, contraindications, and any necessary precautions that should be taken while using the product, ensuring consumer safety. Directions for use guide individuals on how to properly utilize the medication, including dosage instructions and any specific recommendations, which are vital for efficacy and safety.

In contrast, while the price and quantity information may be relevant for consumer decision-making and purchase contexts, they are not among the minimum requirements mandated by regulations for OTC drug labeling. Thus, focusing on active ingredients, warnings, and directions provides a comprehensive understanding of how to use the product responsibly and safely.
