Which act requires child-resistant packaging for most over-the-counter products?

The Poison Prevention Act is the legislation that specifically mandates the use of child-resistant packaging for most over-the-counter products. This act was enacted to help prevent accidental poisonings in children, particularly ensuring that household substances, including medications and certain consumer products, are packaged in a way that is not easily accessible to young children.

The act outlines standards for the design of packaging, ensuring that it's difficult for children to open, while still being easy for adults to use. The implementation of child-resistant packaging has played a significant role in reducing the incidence of poisonings among children, highlighting the importance of safety measures in product design.

In contrast, the Food, Drug, and Cosmetic Act primarily governs the safety and efficacy of drugs and food products rather than specific packaging requirements. The Orphan Drug Act deals with incentives for the development of medications for rare diseases and does not address child safety in packaging. The Drug Price Competition Act focuses on generic drug approval processes and pricing, without any provisions related to packaging safety. Thus, the Poison Prevention Act stands out as the critical piece of legislation for child-resistant packaging in over-the-counter products.
