Results: The prevalence of low adherence to diabetic medication was 45.4% among the study population. Bivariate analysis shows significant association with the patients who are literate (odds ratio [OR] = 0.6, confidence interval [CI] = 0.38–0.95), hypertensive (OR = 1.6, CI = 1.04–2.5), taking treatment from private facility (OR = 0.54, CI = 0.34–0.87), perceived lack of satisfaction with doctor–patient relationship (OR = 3.3, CI = 1.3–8.3), and perceived lack of knowledge about diabetes (OR = 2.03, CI = 1.29–3.1) with low adherence to medication. Conclusions: The prevalence of nonadherence to medications is common among diabetics in rural areas, and there is a need to strengthen the primary health-care system in addressing barriers to achieve better health outcomes.
