The data were collected by means of the demographic and occupational questionnaire and the medication errors questionnaire whose content validity and reliability (Alpha Cronbach's coefficient) have been approved The data were analyzed using descriptive statistics and the Chi-square statistical test through SPSS software V.16. Results: The findings revealed that 66.7 of the nurses had medication errors. 40.6 of the nurses had made medication error only once, and 58.7 of the errors occurred during the night shift. As to the injectable medications, administrating nonprescription medications, making mistakes in dosage calculation, and giving medication after discontinuation were reported with higher frequencies. Regarding the injectable medications, paying no attention to interactions of concomitant drugs, making calculation mistakes, and administrating nonprescription medications were more frequent.

Conclusion: Given the high frequency of medication errors) 66.7 in the last six months( particularly during the night shift as well as the nurses’ fatigue as the most important cause of the error incidences, it appears important that healthcare authorities and nursing managers take account of the approaches that enhance the nurses’ working conditions.
