Which of the following is an exemption to the Poison Prevention Packaging Act (PPA)?

The Poison Prevention Packaging Act (PPA) is designed to prevent children from easily accessing hazardous substances, including prescription medications. Certain exemptions from this requirement do exist, particularly for medications that are determined to pose a minimal risk of poisoning to children.

Oral contraceptives are considered to be a low risk because of their intended use and the specific demographics that utilize them. Therefore, they are exempt from the requirement for child-resistant packaging under the PPA.

Topical products are also exempt, as they are used in a way that generally does not pose a significant risk if ingested in small amounts. Since their intended application is external, they do not necessitate child-resistant packaging in the same way that other medications might.

Liquid antibiotics, on the other hand, typically do not fall under these exemptions because they can be harmful if ingested by children, thus requiring child-resistant packaging to minimize risks.

Therefore, the correct answer encompasses both oral contraceptives and topical products, both of which are recognized as safe from the provisions of the PPA, leading to the conclusion.
