Proper management, medication adherence, and changes in lifestyle lead to control of diabetes and hypertension. Counseling patients is an approach to the management of hypertension and diabetes.

This study aimed to assess the impact of counseling by pharmacists on hypertensive and diabetic patients by reviewing the previous studies who assessed this subject.

The included original English articles reporting counselling of diabetic/and/or hypertensive patients by pharmacists. A total of eight articles met the inclusion criteria and were involved in this review. The total number of patients was 1,390; there were three studies that assessed counseling impact on T2DM patients, three studies conducted on hypertensive patients, and two studies conducted on patients with both diseases.
