Introduction: Accurate documentation of medications using generic names is essential to ensure patient safety , continuity of care, and optimal clinical outcomes. This is particularly important for drugs prescribed in out-of-hospital practitioner (OHP) and outpatient department (OPD) settings when patients are later admitted for the same or recurrent illnesses. Objectives: To assess the adequacy of generic name documentation in medications prescribed in OHP and OPD settings among patients requiring inpatient care. Methods: A cross-sectional clinical audit was conducted in Ward 36, National Hospital, Galle, from November 1, 2025, to January 31, 2026. Data were collected by trained medical personnel using a structured questionnaire based on patients’ previously prescribed medications. Inclusion criteria comprised patients who presented with prior medications (tablet or syrup form) at admission. Results: Among 710 admissions, 580 patients (81%) had a history of prior treatment; 357 were from OHP settings and 227 from hospital OPD services. Only 20% of medications were appropriately labeled with generic names in both settings. Brandname labeling was observed in 15%, while 65% lacked adequate labeling. Similar deficiencies were noted in tablets and syrups. Unsafe practices included non-specific containers, labeling based on tablet color, andabsence of patient identification. Only 35% of medications included the patient’s name and age,though 70% provided clear dosage and frequency instructions. Conclusion: Poor documentation, limited use of generic names, and inadequate labeling increase patient safety risks. Standardized prescribing practices and improved clinician awareness are essential to prevent adverse outcomes and enhance patient care.
