Which of the following drugs can be dispensed without child-resistant containers?

The correct response relates to the specific exemptions in regulations regarding child-resistant containers as mandated by the Poison Prevention Packaging Act (PPPA). Certain prescription medications are classified as requiring special attention due to their safety profile and potential risk if mistakenly ingested by children.

Betamethasone and erythromycin ethylsuccinate are examples of medications that can be dispensed without the requirement of child-resistant containers. This exemption is typically granted because the packaging of these drugs is not deemed necessary for preventing accidental ingestion by children, likely due to factors such as the nature of the medication, its intended use, and the population typically prescribed this medication.

For instance, betamethasone is a corticosteroid used primarily in adults for a variety of conditions, and erythromycin ethylsuccinate is an antibiotic that is generally prescribed and instructed for adult use or in specific pediatric cases where the prescribing physician assesses the risks. In contrast, the other medication pairs listed have characteristics or previous historical considerations that typically mandate child-resistant packaging to mitigate risks of accidental ingestion.
