What is required before administering an over-the-counter topical medication?

The requirement that the skin must be intact before administering an over-the-counter topical medication is crucial for ensuring safety and effectiveness. Topical medications are designed to be applied to the skin and work locally. When the skin barrier is compromised, such as in the presence of cuts, wounds, or rashes, the medication can be absorbed more systemically, potentially leading to side effects or adverse reactions that are not intended. Furthermore, an intact skin barrier helps to ensure that the medication performs its intended action without causing further irritation or complications.

Other choices do not align with standard practices for administering topical medications. While a physician's prescription or a pharmacist's verification may be necessary for some medications, over-the-counter topical medications often do not require them. Similarly, while patient consent is important, simply having verbal approval does not adequately address the specific requirement for the condition of the skin, which is critical for safe administration.
