A medication-dispensing unit is provided for tracking medical products having a Radio Frequency Identification (RFID) tag uniquely associated therewith. The dispensing unit includes compartments for receiving medical products therein, and readers for reading the RFID tags associated with the medical products in the compartments. A processor is coupled to the readers for receiving and processing readings of the RFID tags in the compartment to identify the medical products in the compartments. The processor may identify a medical product removed from a compartment by determining a difference between readings of the RFID tags in the compartment taken before and after the medical product is removed from the compartment. The processor may verify that the medical product removed from the compartment is authorized to be removed or confirm that an identified patient is intended to receive the medical product being removed from the compartment.

1. A method for monitoring unit dose medical products stored in a medication-dispensing unit, each of the unit dose medical products comprising a Radio Frequency Identification (RFID) tag uniquely associated therewith, the method comprising:removing a unit dose medical product from the dispensing unit; identifying the unit dose medical product removed from the dispensing unit by detecting removal of the RFID tag associated with the medical product removed from the dispensing unit; verifying that the unit dose medical product removed from the dispensing unit is authorized to be removed from the dispensing unit, the verifying step comprising comparing a product name identified by the RFID tag removed from the dispensing unit with a product authorized to be removed from the dispensing unit; and further comprising identifying a patient, and wherein the verifying step further comprises comparing a product name identified by the RFID tag removed from the dispensing unit with a list of medical products scheduled for delivery to the identified patient and assigning the removed unit dose medical product to an individual patent to ensure that the correct medical product is delivered to the patient. 2. The method of claim 1, further comprising:returning a medical product to the dispensing unit; and reading an RFID tag associated with the medical product to identify the returned medical product. 3. The method of claim 2, further comprising determining an intended patient for the returned medical product, and sending a notice that the intended patient did not receive the returned medical product.4. A method for monitoring unit dose medical products as in claim 1 wherein the unit dose medical products are medication containers each comprising one of a vial, bottle or bag.5. A method for monitoring unit dose medical products stored in a medication-dispensing unit, each of the unit dose medical products comprising a Radio Frequency Identification (RFID) tag uniquely associated therewith, the method comprising:removing a unit dose medical product from the dispensing unit; identifying the unit dose medical product removed from the dispensing unit by detecting removal of the RFID tag associated with the medical product removed from the dispensing unit, wherein the steps of identifying the medical product removed from the dispensing unit further comprises: reading the RFID tags of the medical products in the dispensing unit before the medical product is removed from the dispensing unit; reading the RFID tags of the medical products in the dispensing unit after the medical product is removed from the dispensing unit and assigning the unit dose medical products to respective individual patients to ensure that correct medical products are delivered to the patients; and determining a difference between the readings of the RFID tags taken before and after the medical product is removed from the dispensing unit to identify the unit dose medical product removed. 6. The method of claim 5, wherein the verifying step comprises comparing a product name identified by the RFID tag removed from the dispensing unit with a product name authorized to be removed from the dispensing unit.7. The method of claim 6, wherein the product name of the medical product removed from the dispensing unit is obtained by reading the RFID tags before the medical product is removed from the dispensing unit.8. The method of claim 5, further comprising identifying a patient, and wherein the verifying step further comprises comparing a product name identified by the RFID tag removed from the dispensing unit with a list products scheduled for delivery to the identified patient.9. The method of claim 8, wherein the product name of the medical product removed from the dispensing unit is obtained by reading the REID tags before the medical product is removed from the dispensing unit.10. A method for monitoring unit dose medical products as in claim 5 wherein the unit dose medical product removed from the dispensing unit is assigned to an individual patient upon removal from the dispensing unit.11. A method for monitoring removal of unit dose medical products stored in a medication-dispensing unit, each of the unit dose medical products comprising a Radio Frequency Identification (RFID) tag uniquely associated therewith, the method comprising:reading the RFID tags of the unit dose medical products in the dispensing unit before removing one or more medical products from the dispensing unit; removing one or more unit dose medical products from the dispensing unit; reading the RFID tags of the medical products in the dispensing unit after the one or more medical products are removed from the dispensing unit; and determining a difference between the readings of the RFID tags taken before and after the one or more medical products are removed from the dispensing unit to identify the one or more unit dose medical products removed from the dispensing unit, and assigning the unit dose medical products to respective individual patients to ensure that correct medical products are delivered to the patients. 12. The method of claim 11, further comprising verifying that the one or more medical products removed from the dispensing unit are authorized to be removed from the dispensing unit.13. The method of claim 12, wherein the verifying step comprises comparing a product name identified by an RFID tag removed from the dispensing unit with a product name authorized to be removed from the dispensing unit.14. The method of claim 12, further comprising identifying a patient, and wherein the verifying step further comprises comparing a product name identified by the RFID tag removed from the dispensing unit with a list of medical products scheduled for delivery to the identified patient.15. The method of claim 11, further comprising transmitting an inventory notice from the dispensing unit when a quantity of RFID tags stored within the dispensing unit falls below a threshold.16. The method of claim 11, further comprising:returning a medical product to the dispensing unit; reading the RFID tags of the medical products in the dispensing unit after the medical product is returned to the dispensing unit; and determining a difference between the readings of the RFID tags taken before and after the medical products are returned to the dispensing unit to identify the medical product returned to the dispensing unit. 17. The method of claim 16, further comprising determining an intended patient for the returned medical product, and sending a notice that the intended patient did not receive the returned medical product.18.
