Background: Hypertension affects about 1.5 billion persons worldwide. Compliance to appropriate medical therapy for hypertension can result in controlled blood pressure and reduction in adverse outcomes.Objective: To determine the relationship between knowledge, attitudes and medication compliance in patients diagnosed with hypertension. Method: A cross-sectional, descriptive study was conducted with 386 hypertensive patients (60.4% female, mean age: 60.6 ± 12.6). The researcher used a questionnaire with total of 38 questions. Determine the relationship between these variables by the Chi squared test.Results: The rate of good knowledge of medication usage in outpatients diagnosed with hypertension was 55.7%; the rate of positive attitudes was 35.8% and 49.5% of patients with medication compliance.There were significant differences between knowledge about medication use with age, education level, occupation, income, health insurance (p<0.05). Education level was significant relationship of attitudes toward medication use ((p<0.05). Patients who were ≥ 50 years of age reported high medication compliance (p=0.032).There was a correlation between attitudes toward medication use and medication compliance (OR = 1.78, 95% CI: 1.17- 2.71, p = 0.007). Between knowledge of medication usage and medication compliance showed no significant relationship (p>0.05). In patients who were compliance and non-compliance with medication showed that there was significantly associated between knowledge and attitudes toward medication use (OR=3.07, 95%CI:1.65-5.72,p<0.001).Conclusion: Patients who had positive attitudes toward medication use, who were ≥ 50 years of age reported high medication compliance.
