Nobesit 850 mg is an oral antihyperglycemic medication manufactured by Incepta Pharmaceuticals Ltd., containing metformin hydrochloride as its active ingredient. Belonging to the biguanide class, it is primarily used to manage type 2 diabetes mellitus, especially in overweight patients when dietary management and exercise alone do not result in adequate glycemic control. Metformin works by decreasing hepatic glucose production, reducing intestinal glucose absorption, and improving insulin sensitivity, thereby lowering both basal and postprandial plasma glucose levels without causing hypoglycemia. Nobesit 850 mg is typically administered with meals to minimize gastrointestinal side effects such as nausea and abdominal discomfort. The dosage is individualized based on effectiveness and tolerance, with the maximum recommended daily dose being 2550 mg for adults. Common side effects may include diarrhea, nausea, vomiting, gas, weakness, indigestion, abdominal pain, headaches, and decreased appetite. It is important to follow the prescribed dosage and consult a healthcare provider for personalized medical advice
