Hypertension is a major public health concern with a high prevalence and significant impact on morbidity and mortality. Non-adherence to antihypertensive medication remains a critical challenge, often influenced by patients’ knowledge levels. This study aimed to examine the relationship between knowledge and medication adherence among hypertensive patients in the working area of Penujak Public Health Center, Praya Barat District, Central Lombok Regency. A quantitative approach with a cross-sectional design was employed. A total of 73 respondents were selected from 267 hypertensive patients using Slovin’s formula and purposive sampling technique. Data collection utilized a knowledge questionnaire and the Morisky Medication Adherence Scale (MMAS-8), both tested for validity and reliability. Data analysis applied Chi-Square with a significance level of p<0.05. The results indicated that 47.9% of respondents had low knowledge and 71.2% demonstrated low adherence. Statistical analysis revealed a significant relationship between knowledge and medication adherence (p=0.021). Patients with moderate to high knowledge levels showed better adherence than those with low knowledge. These findings underscore the necessity of continuous health education to improve patients’ understanding and adherence to therapy, thereby reducing long-term complications.
