Which of the following actions can a pharmacist take regarding prescription refusal?

A pharmacist has a professional responsibility to ensure that patient safety is prioritized. The scenario in which a pharmacist can refuse to fill a prescription if doing so could harm the patient is rooted in the pharmacist's duty to act in the patient's best interests. This could involve situations where the prescribed medication might interact adversely with other medications the patient is taking, where there are significant allergies involved, or where there could be a detrimental impact on the patient's health due to other factors.

This aligns with ethical principles and legal requirements in pharmacy practice, where safeguarding a patient's well-being is paramount. If a pharmacist believes that filling the prescription would result in harm, it becomes not just a right but an obligation to refuse to dispense the medication. This protective stance is essential in maintaining the integrity of pharmaceutical care and ensuring that patients receive safe and appropriate treatment.
