The pharmacy at Mercy Hospital fills medical prescriptions for all hospital patients and distributes these medications to the nurse stations responsible for the patients' care. Prescriptions are written by doctors & sent to the pharmacy.  A pharmacy technician reviews every prescription and sends it to the appropriate pharmacy station.  Prescriptions for drugs that must be formulated (made on-site) are sent to the lab station, prescription for off-the-shelf drugs are sent to the shelving station, and prescriptions for narcotics are sent to the save station.  At every station, a pharmacist reviews the order, checks the patient's file to determine the appropriateness of the prescription, and fills the order if the dosage is at a safe level and it will not negatively interact with the other medications or allergies indicated in the patient's file.
