This cross-sectional study was conducted in 2016. A total of 42 Pharmacists participated in the survey while a total of 270 Registered Nurses were selected from nurses working at the study centre using consecutive sampling method (n=312). Reliability coefficient was 0.84; Kruskal-Wallis test and T-Test were applied to test hypothesis at α = 0.05 level of significance. Results showed that about 33 (90.5%) of pharmacists and 178 (68.7%) of nurses were previously involved in Medication Errors (MEs). Furthermore, the most common types of MEs among the respondents were wrong patients, giving the wrong medications, wrong dosage and wrong dosage form. The extent of respondents’ action to MEs after recognition varied although the pharmacists had greater positive attitudes (mean= 3.76) towards MEs than the nurses (mean= 3.5). The Kruskal-Wallis test results showed that there was significant difference (p<0.05) between the types of medication error and the action to medication errors among pharmacists and nurses. However, t-test result showed that there was no significant difference between pharmacists and nurses in their action to medication errors at UPTH p-value (0.212)
