Abstract

Methods, systems, computer program products, and data structures are used for dispensing medication and verifying proper medication use. Medication of a purported type and dosage is dispensed into an individualized patient medication dispensing cup. The cup includes a bar code that associates a designated patient with the dispensed medication. The cup is placed on a network connected scale. Through network communication the scale accesses medication and patient information. From the accessed information (e.g., medication weight data), the scale determines if it is appropriate to administer the dispensed medication to the designated patient and visual indicates the determination. When it is appropriate to administer the medication, it is transported on a secure cart to a patient location. Sensors (e.g., RFID or ultrasound) detect if the dispensed medication is prescribed for the patient at the patient location. When a medication error is detected at any time during dispensing or administration of medication, staff members are alerted.
