30. 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?
Answer: D
Dispensing the donepezil 5 mg prescription first and the donepezil 10 mg prescription about four weeks later
Implementing a strategy of dispensing the donepezil 5 mg prescription first and the donepezil 10 mg prescription about four weeks later would effectively align with the prescribed treatment plan. This approach ensures the patient follows the intended titration schedule, reducing the risk of confusion regarding simultaneous dosing.
A) Having a pharmacy technician counsel the patient regarding how to take their medications
While counseling patients is important, it does not directly address the root cause of the error in this scenario. A patient might still misunderstand or mismanage their medication regimen, especially if they have received both prescriptions at the same time.
B) Dispensing #58 donepezil 10 mg tablets and updating the instructions for the patient
This option would not be advisable as it could lead to further confusion for the patient, who is not yet due to start the higher dose. The instructions would contradict the original treatment plan, potentially resulting in overdose or adverse effects.
C) Placing auxiliary labels on the vials to indicate that the 10 mg tablets should be taken first and the 5 mg second
Although auxiliary labels may provide additional information, they do not resolve the fundamental issue of the patient receiving both strengths simultaneously. This could still lead to misinterpretation and improper use of the medications.
D) Dispensing the donepezil 5 mg prescription first and the donepezil 10 mg prescription about four weeks later
This option is the most effective strategy as it follows the prescribed treatment plan and ensures the patient uses the medications as intended. By staggering the prescriptions, it minimizes the risk of confusion and potential dosing errors.
Conclusion
Dispensing the donepezil 5 mg prescription first and delaying the donepezil 10 mg prescription is the best approach to prevent similar medication errors in the future. This strategy directly addresses the need for proper titration and adherence to the prescribed regimen. All other options fail to adequately mitigate the risk of confusion or mismanagement of the patient's medications.
