Final answer:
When a DUR warning appears when entering a prescription, it is important to consult the drug interaction database and potentially contact the prescriber for clarification.
Step-by-step explanation:
When a DUR (Drug Utilization Review) warning appears when entering a prescription, it is important to take appropriate action to ensure patient safety. One should consult the drug interaction database to evaluate potential drug interactions or other safety concerns. This will provide information on whether the prescribed medication may cause harm or interact with other medications the patient is taking. Once the information is assessed, one may need to contact the prescriber for clarification if the warning indicates a specific issue that needs attention.
