Aims: Prospective pharmacist’s interventions aimed to improve patient’s knowledge and behaviors to adhere to medications in patients with type 2 diabetes with or without cardiovascular medical conditions in primary health care (PHCs) centers in Nyala city, South Darfur State, Sudan. Methodology and Materials: 300 patients were enrolled for assessing adherence with the Brief Medication Questionnaire (BMQ) in ten PHCs in Nyala city. We assessed patients’ responses to BMQ pre-and post-interventions plan by: complex interventions, humanitarianism and disease outcomes determined by health-related outcomes (SF-36), glycosylated hemoglobin (HbA1c) and blood pressure. Results: BMQ scores have improved significantly in four screens (pre-and post-interventions): regimen [4.6 ± 0.2 to 1.8 ± 0.1; P = 0.001], belief [1.6 ± 0.3 to 0.3 ± 0.3; P = 0.007], recall [1.7 ± 0.2 to 0.6 ± 0.2; P = 0.043] and access screens [1.8 ± 0.1 to 0.4 ± 0.1; P = 0.005]; which have indicated an improved patients’ adherence to medications. Percentage of subjects reaching target of post prandial blood glucose (PPBG) have increased from 28.0% to 49.3%; [P = 0.02] post interventions. PPBG mean values have decreased significantly from [11.1 ± 0.6 mmol/L to 8.1 ± 0.8 mmol/L;
