If a patient experiences an adverse reaction, which action best describes the pharmacist's response?

• A. Document the reaction in the patient file and notify the pharmacy manager.
• B. Report the reaction to the prescribing physician and monitor the patient's condition.
• C. Ignore the reaction unless it is life-threatening.
• D. Stop all medications until the physician approves.

Answer: (B)

When a patient experiences an adverse reaction, immediate clinical management and communication with the prescriber are essential. The pharmacist serves as a safety bridge, helping ensure the patient isn’t left with unresolved symptoms and that the therapy can be reassessed promptly. Reporting the reaction to the prescribing physician allows the clinician to determine causality, adjust the treatment plan if needed, and provide specific instructions for monitoring. Ongoing observation of the patient’s condition helps catch any progression or improvement quickly, so changes can be made in a timely and safe manner.

While documenting the reaction in the patient’s record is part of good practice, and informing the pharmacy manager may be necessary for institutional safety processes, these steps do not substitute for clinical action. Other options—ignoring the reaction or stopping all medications without a physician’s directive—pose clear safety risks and can harm the patient. The core responsibility is to ensure the patient is evaluated and managed in collaboration with the prescriber, with careful monitoring until stability is confirmed.
