<![CDATA[Hypertension is a public health problem with high prevalence whose management is strongly influenced by self care behavior. This study aims to determine the level of success in changing self care behavior in maintaining blood pressure among hypertensive patients. The study used a quantitative design with a one-group pretest-posttest approach involving 60 respondents selected through purposive sampling. Data were collected using a closed questionnaire administered face to face before and after the intervention, then analyzed using the Wilcoxon Signed Rank Test and Spearman Correlation. The results showed a significant increase in the proportion of respondents in the Good self care category from 53.3% to 81.7% (p=0.000), accompanied by a decrease in systolic blood pressure from 137.9 mmHg to 134.7 mmHg and diastolic blood pressure from 81.4 mmHg to 80.5 mmHg (p<0.05). Self care was significantly associated with systolic blood pressure at pretest (p=0.020), but this association weakened and became non-significant at posttest (p=0.450). This study concludes that self care education intervention is effective in improving self care behavior and reducing blood pressure among hypertensive patients. Primary healthcare services are recommended to integrate ongoing self care education to support optimal blood pressure control.]]>
