Which auxiliary label must be added to topical solution prescriptions?

• A. For external use only
• B. Keep refrigerated
• C. Shake well before use
• D. Do not ingest

Answer: (A)

For topical medications, the crucial safety message is that the product is intended for external use only. This clearly communicates to patients and caregivers that the solution should be applied to the skin or mucous membranes and not swallowed or used internally. Ingesting topical solutions can cause serious harm, depending on the ingredients, so marking them as for external use helps prevent accidental or purposeful misuse. Other labels are useful in specific situations but aren’t universal requirements for all topical solutions: keeping the product refrigerated is only necessary if the formulation is unstable at room temperature; shaking before use is needed for suspensions or emulsions to ensure the dose is uniform; and a caution like “do not ingest” may apply in some cases, but the blanket, always-required label for topical prescriptions is external use only.
