Which of the following actions should you take if you suspect a drug–drug interaction on the MAR?

• A. Ignore the warning if you are uncertain
• B. Notify the clinician and monitor for signs of interaction
• C. Immediately stop all medications involved
• D. Record the concern and proceed without changes

Answer: (B)

When you suspect a drug–drug interaction, the priority is to escalate the issue to the clinician so they can assess risk, adjust therapy if needed, and monitor for effects. Interactions can change how drugs work or increase toxicity, so timely evaluation helps keep the patient safe. The best action is to notify the clinician and monitor for signs of interaction, enabling a informed decision about dose changes, hold orders, or alternative therapy. Ignoring the warning, stopping all medications, or simply recording the concern without taking action could delay necessary evaluation and put the patient at risk.
