After the patient, drug, and prescriber information has been entered (often by a technician or pharmacy intern), the prescription is double checked (by a registered pharmacist) to ensure the information was entered accurately. Intercom Plus's Automatic Label Printing System (ALPS) program generates a leaflet for the prescription. The technician then scans the leaflet on a Check-weigh Scale and the system generates a vial label for the prescription after the system performs a National Drug Code (NDC) validation via scanner. The vial label is placed appropriately sized container for the prescription. The system automatically checks the patient's current medication list for any potential drug interactions via Drug Utilization Reviews (DUR).
