In June 2025 we published a detailed guide on Glucophage, the brand name many know for metformin. This archive page sums up the key points: what metformin does, who it helps, common side effects, and simple daily tips to get the most out of it safely.
Metformin lowers blood sugar mainly by reducing how much glucose your liver releases and by improving insulin sensitivity in muscle. Doctors usually prescribe it as first-line treatment for type 2 diabetes. Many people see meaningful drops in fasting glucose and A1c when they combine metformin with diet and activity. If you’re newly diagnosed, on a tight budget, or looking for a well-studied option, metformin often comes up first.
Real-world example: someone in their 50s who added metformin and walked 30 minutes most days often reports lower morning glucose and fewer highs after meals within a few weeks. Results vary, but that practical combo tends to help a lot of people.
Start low and go slow. GI upset—nausea, diarrhea, and bloating—is common at first. Taking metformin with food or switching to an extended-release (XR) formula usually fixes that. If itching or rash appears, tell your provider right away.
Check kidney function before you start and periodically after that. Metformin is cleared by the kidneys, so doses may need adjusting if kidney function drops. Ask your provider whether you should pause metformin before certain imaging tests or surgeries; they’ll give specific timing based on your test and kidney numbers.
Lactic acidosis is very rare but serious. Seek care for unexplained severe weakness, breathing trouble, or persistent stomach pain. Most people can avoid problems by staying hydrated, limiting heavy alcohol use, and keeping routine lab checks.
Drug interactions matter. Some blood pressure meds, certain antibiotics, and other diabetes drugs can affect how metformin works or how your kidneys handle it. Share a full medication list with every clinician you see.
Simple dosing notes: many start at 500 mg once or twice daily, then increase slowly. XR formulas allow once-daily dosing for some people. Never change dose without checking with your clinician.

If you or a family member take metformin, keep a brief record: current dose, A1c results, kidney numbers, and notes on side effects. That makes checkups faster and helps your clinician adjust treatment more precisely.
