The pharmacy at Mercy Hospital fills medical prescriptions for all patients and distributes these medications to the nurse stations responsible for the patient's care. Medical prescriptions are written by doctors and sent to the pharmacy. A pharmacy technician reviews the prescriptions and sends them to the appropriate pharmacy station. Prescriptions for drugs that must be formulated (made on site) are sent to the lab stations, prescriptions for off the shelf drugs are sent to the shelving station, and prescription for narcotics are sent to the secure station.

At each station, a pharmacist reviews the order, check the patient's file to determine the appropriateness of the prescriptions, and fills the order if the dosage is at a safe level and is will not negatively interact with the other medications or allergies indicated in the patient's file. If the pharmacist does not fill the order, the prescribing doctor is contacted to discuss the situation. In this case, the order may ultimately be filled or the doctor may write another prescription depending on the outcome of the discussion. Once filled, a prescription label is generated listing the patient's name, the drug type, and dosage, an expiration date, and any special instructions. The label is placed on the drug container and the orders are sent to the appropriate nurse stations. The patients admission number, the drug type and amount dispensed, and the cost of the prescription are then sent to the billing department.
