The prescription is written by the doctor and sent to the pharmacy where the pharmacist reviews the prescription, checks the patient drug file to determine the appropriateness by checking with the allergy notification system. The pharmacist then fills the order if the dosage is safe, there are no known patient allergies to the drug, and the drug does not interact with other drugs the patient is taking. If the pharmacist decides not to fill the order the doctor is contacted and advised of the problem. The doctor then may decide to have the order filled anyway or the doctor may write another prescription and resubmit it to the pharmacy. Once the prescription is filled a label is generated with the patient information (patient ID number, patient name, room number, doctor name etc), prescription information (drug name, amount dispensed, dosage) and medical information (instructions). The label is put on the drug container. The Patient ID and new drug information (drug, dosage, RX #) are entered by the pharmacy into the Patient Drug File. The patient ID number, drug name, amount dispensed and cost of the drug are entered by the pharmacy into the on-line cost center system. The drug container (with drug) and the corresponding order are then sent to the appropriate Nurse Station to be administered to the patient
