Methods: The study was conducted at the Obafemi Awolowo University Teaching Hospitals; Ile-Ife and Ilesa; Nigeria. Data was collected by the use of pre-tested questionnaire administered to 35 pharmacists and a stratified sample of 130 nurses over a period of 2 weeks. The questionnaires were sorted and analysed. Results: The pharmacists that responded (80) cited incorrect drug; incorrect strength of drug (70) and wrong dose of drug (60) as the most common dispensing errors. Fifty percent of pharmacists put the estimated frequency of occurrence of these dispensing errors at 1 per 100 prescriptions dispensed. Most of the nurses (65) identified administration of wrong drug; administration of wrong dose (63) and wrong time of drug administration (57) as the most frequently occurring medication administration errors in the teaching hospital. All the pharmacists and 78of nurses identified excess workload as the most important factor contributing to errors in medication dispensing and administration respectively. Conclusion: The fundamental factor perceived to be contributing to errors in medication dispensing and administration was excess workload resulting from insufficient members of staff.) cited incorrect drug; incorrect strength of drug (70) and wrong dose of drug (60) as the most common dispensing errors.
