About
Metformin is an oral biguanide antihyperglycemic agent widely recognized as a cornerstone in the management of type 2 diabetes mellitus. Its primary mechanism of action involves reducing hepatic glucose production, which is a major contributor to elevated fasting blood sugar levels. Additionally, metformin decreases the intestinal absorption of glucose and significantly improves insulin sensitivity by enhancing peripheral glucose uptake and utilization in muscle and fat tissues. This multifaceted approach helps to lower both fasting and postprandial blood glucose levels effectively. Unlike some other antidiabetic medications, metformin does not stimulate insulin secretion from the pancreas, thereby minimizing the risk of hypoglycemia when used as monotherapy. It is frequently prescribed as a first-line treatment, especially for overweight and obese patients with type 2 diabetes, owing to its beneficial effects on weight management and lipid profiles. Its efficacy and well-established safety profile make it a preferred choice for initiating therapy and for long-term glycemic control in many individuals with type 2 diabetes.

Safety Measures
- Alcohol - Avoid excessive alcohol intake as it can increase the risk of lactic acidosis, a rare but serious side effect of metformin.
- Pregnancy - Consult your doctor. Metformin may be used during pregnancy if clearly needed, but insulin is often preferred for glycemic control.
- Breastfeeding - Small amounts pass into breast milk. Generally considered compatible, but monitor the infant for adverse effects. Consult a healthcare professional.
- Liver - Use with caution in patients with impaired liver function as it may increase the risk of lactic acidosis. Not recommended in severe hepatic impairment.
- Kidney - Contraindicated in severe renal impairment (eGFR <30 mL/min/1.73m²). Dose adjustment is required for moderate renal impairment.
- Lung - Generally safe for use in patients with lung conditions, but severe respiratory failure can increase lactic acidosis risk.
