🛒 Compare PricesWhat is Metformin?
Metformin is a prescription medication used to treat type 2 diabetes. It belongs to a class of drugs called biguanides. It helps control blood sugar levels by reducing glucose production in the liver, decreasing intestinal absorption of glucose, and improving insulin sensitivity. It is often the first medication prescribed for newly diagnosed type 2 diabetes.
Metformin may also be used for other conditions, including prediabetes and polycystic ovary syndrome (PCOS), as directed by a healthcare provider.
What is Metformin Used For?
According to the FDA, metformin is approved to treat:
- ✔️ Type 2 diabetes mellitus – helps lower blood sugar levels in adults and children over 10 years old.
- ✔️ Prediabetes – may help delay or prevent progression to type 2 diabetes in high-risk adults.
Doctors may also prescribe it off-label for PCOS and other metabolic conditions. Always follow your prescriber's instructions.
Available Dosages and Forms
Metformin is available as oral tablets in several strengths and formulations:
- Immediate-release tablets: 500 mg, 850 mg, 1000 mg
- Extended-release tablets: 500 mg, 750 mg, 1000 mg
- Oral solution: 500 mg/5 mL
Generic metformin is available in the same strengths and is equally effective, usually at a lower cost.
Brand Glucophage vs Generic Metformin
Both contain the same active ingredient and meet the same FDA standards for quality, safety, and effectiveness. The only significant difference is price: generic metformin is typically much less expensive. Most insurance plans prefer or require generics.
When comparing prices, you may see both options. Choose the one that best fits your budget and prescription.
How to Take Metformin Safely
Always follow your healthcare provider's instructions. Metformin is usually taken with meals to reduce stomach upset. Dosage may be gradually increased to improve tolerance.
- Take metformin with a meal, unless your doctor tells you otherwise.

- Take it at the same time(s) each day.
- Do not stop taking it without consulting your doctor, even if you feel well.
- Monitor your blood sugar regularly and keep all lab appointments.

Like all medications, metformin may cause side effects. The most common include:
- Nausea
- Diarrhea
- Stomach upset or abdominal pain
- Loss of appetite

Serious side effects are rare but require immediate medical attention, including lactic acidosis (symptoms: muscle pain, weakness, trouble breathing, severe drowsiness). This is not a complete list. Read the full FDA label or consult your pharmacist.
