Hypoglycemia is serious concern in diabetic population. Hypoglycemia commonly causes brain fuel deprivation, resulting in functional brain failure, which can be corrected by raising plasma glucose concentration. People with diabetes should become concerned about the possibility of hypoglycemia at a self-monitored blood glucose level (?70mg/dl) or (3.9mmol/litre). Hypoglycemia is common in type-1 diabetes, especially in patients receiving intensive therapy, in whom the risk of severe hypoglycemia is increased more than threefold (. They suffer an average of two episodes of symptomatic hypoglycemia per week, thousands of such episodes of symptomatic hypoglycemia per week and one episode of severe, at least temporarily disabling hypoglycemia per year. Increased risk among women, African Americans, those with less than high school education, aged participants. The aim of present study was to assess the role of diabetic education in increasing the awareness about hypoglycemia symptoms in diabetic patients. The study was conducted with the approval of the institutional ethical committee of Sri Padmavathi School of pharmacy, Tiruchanoor. A questionnaire that consisted of both closed and open-ended questions on knowledge, attitude and practices were designed and applied. Patients who are diagnosed with diabetes mellitus and patients receiving anti diabetic medications were included in the study. In this study majority of the people thinks that by not eating food the blood sugar levels fall down. Out of 350 patients 160 (45.714%) eats sugar when glucose levels are low, 110 (31.42%) eats sugar candies, 58(16.571%) drinks fruit juices, 32 (9.142%) drinks soft cool drinks and none of the patients eats glucose tablets and honey during hypoglycaemic attack. We conclude that a clinical pharmacist plays main role in improving the knowledge of health seeing care of the patients towards the disease creating awareness, providing general information about disease, prevention, management and benefits of the treatment
