Final answer:
A patient's drug therapy record includes their personal information, prescription details, medication dosage and instructions, and any noted side effects or interactions. Pharmacists are responsible for maintaining these records, ensuring medication safety and efficacy as per FDA regulations.
Step-by-step explanation:
A patient's drug therapy record should retain comprehensive information on all prescriptions filled at a pharmacy to ensure ongoing patient safety and track medication history. Key details that must be included are the patient's name and contact information, the prescribing physician's details, the date the prescription was filled, the name and dosage of the medication, directions for use, quantity supplied, and any side effects or drug interactions noted.
Moreover, it's essential to record the specific batch number of the medication dispensed and the expiration date. A pharmacist plays a critical role in this process by not only dispensing medication but also monitoring pharmacovigilance, advising on drug interactions, and ensuring the appropriate usage of medications according to their chemical and biological effects on the body. Vigilant record-keeping contributes to the safety and effectiveness of drug therapy and fulfills the legal and professional requirements set by the Food and Drug Administration (FDA) and other regulatory bodies.
