4. A pharmacy receives the following prescriptions: Donepezil 5 mg #28 1 tablet by mouth daily for 4 weeks, then increase to Donepezil 10 mg #30 1 tablet by mouth daily thereafter 5 refills The prescriptions are both dispensed, and the patient reports taking both strengths daily. Which would be the best strategy to prevent similar errors?
Answer: D
Dispensing the donepezil 5 mg prescription first and the donepezil 10 mg prescription about four weeks later is the best strategy.
This approach ensures that the patient receives the correct dosage at the appropriate times, thereby preventing confusion and potential medication errors.
A) Having a pharmacy technician counsel the patient regarding how to take their medications
While counseling is essential in pharmacy practice, it may not effectively prevent errors in this scenario. The patient has already reported taking both strengths daily, indicating that verbal instructions alone may not resolve the issue of confusion regarding the dosing schedule.
B) Dispensing #58 donepezil 10 mg tablets and updating the instructions
Dispensing the higher dosage prematurely could exacerbate the problem, as the patient would not be following the intended titration schedule. This could lead to an increased risk of side effects or toxicity from taking the stronger dose too soon.
C) Placing auxiliary labels on the vials to indicate that the 10 mg tablets should be taken first
This option could confuse the patient further, as it contradicts the prescribed dosage schedule. If the patient is instructed to take the 10 mg tablets first, it undermines the titration plan intended by the healthcare provider.
D) Dispensing the donepezil 5 mg prescription first and the donepezil 10 mg prescription about four weeks later
This option aligns with the prescribed treatment plan, allowing the patient to start at the appropriate lower dose and transition to the higher dose after the specified period. This method minimizes the risk of confusion and ensures adherence to the prescribed regimen.
Conclusion
Dispensing the donepezil 5 mg prescription first and the 10 mg prescription later is the most effective strategy to prevent confusion and ensure patient safety. The other options either do not address the core issue of the dosage schedule or could lead to further complications. By adhering to the prescribed titration plan, the pharmacy can better support the patient’s treatment and minimize the risk of medication errors.
