What Experts Say

Metformin is a biguanide that lowers blood sugar mainly by reducing the amount of glucose the liver releases into the bloodstream. It also improves the sensitivity of muscle and fat cells to insulin and slightly slows glucose absorption in the gut. Because it does not push the pancreas to release more insulin, it carries little risk of hypoglycemia on its own.

The 500mg strength is often the starting dose used to introduce metformin gradually, allowing the digestive system to adjust before the dose is increased. Doctors commonly begin treatment once or twice daily with meals and review blood sugar response over several weeks before adjusting further. This step up approach reduces the chance of stomach related side effects.

Regular monitoring of kidney function is recommended throughout treatment, since metformin is cleared by the kidneys and its dose depends on how well they work. Lactic acidosis is rare but serious, and risk increases with dehydration, heavy alcohol use, or acute illness. Mild nausea or loose stools early in treatment usually settle without stopping the medicine.

Drug Interactions

• Contrast Dye: Iodinated contrast media used in imaging can affect kidney function and raise lactic acidosis risk.
• Diuretics: May affect kidney function and blood sugar control when taken alongside metformin.
• Corticosteroids: Can raise blood sugar and work against metformin's effect.
• Cimetidine: May increase metformin levels in the blood, raising side effect risk.
• Other Antidiabetic Drugs: Combining with insulin or sulfonylureas raises the risk of hypoglycemia.

Risks and warnings

• Lactic Acidosis: A rare but serious risk, higher in patients with kidney disease, liver disease, or heavy alcohol use.
• Kidney Function: Doctors typically check kidney function before starting and periodically during treatment.
• Vitamin B12: Long term use may lower vitamin B12 levels, so periodic testing is advised.
