The prescriptions are both dispensed, and the patient is hospitalized after several weeks. The patient reports that they have been taking both strengths of donepezil daily. Which of the following would be the best strategy to implement to prevent similar errors in the future?

While patient counseling is crucial, relying solely on verbal instructions may not sufficiently address potential confusion, especially if the patient has memory or comprehension issues. Directly controlling the dispensing sequence can provide a more concrete safeguard against dosage errors.

Increasing the total quantity of the higher-strength medication and updating instructions may not address the fundamental issue of concurrent administration of different strengths. Moreover, a higher quantity does not necessarily mitigate the risk of unintentional double dosing.

While labeling can help improve medication adherence, it may not prevent initial errors in dosage regimen comprehension or execution. Reliance solely on labeling might not sufficiently mitigate the risk of simultaneous ingestion of different strengths.
