Metformin — What You Really Need to Know

Metformin is one of the most commonly prescribed medicines for type 2 diabetes. It lowers blood sugar, is usually cheap, and works well for a lot of people. But that doesn’t mean everyone uses it right or knows the risks.

How metformin works

Metformin reduces glucose production in the liver and helps your body use insulin better. It comes as immediate-release and extended-release tablets. Doctors often start low and increase dose slowly. Typical starting doses are 500 mg once or twice a day, and many people end up on 1500–2000 mg daily if tolerated.

Practical tips & safety

Take metformin with food to cut down on stomach upset. The most common side effects are nausea, diarrhea, and bloating during the first weeks. These usually get better if you stick with a slow dose increase or switch to extended-release tablets.

Serious problems are rare but worth knowing. Metformin can affect vitamin B12 levels, so ask your provider about a B12 check if you feel weak or have numbness. People with very poor kidney function should not take metformin—doctors watch kidney tests before and during treatment. If you’re having an imaging test that uses iodinated contrast, your doctor may tell you to stop metformin briefly and restart it after your kidney tests look normal.

Metformin is also used off-label for conditions like polycystic ovary syndrome (PCOS), often to help with insulin resistance. If you’re trying to conceive or are pregnant, talk to your doctor—use in pregnancy requires careful discussion.

Drug interactions are usually low, but tell your clinician about other medicines and supplements you take. Alcohol can increase the risk of side effects for some people, so keep drinking moderate and discuss risks if alcohol is regular in your life.

Monitoring matters. Expect periodic blood tests for blood sugar control and kidney function. If you notice persistent stomach pain, muscle pain, shortness of breath, or sudden fatigue, contact your provider right away—these symptoms may need urgent review.

If side effects bother you, options exist. Switching to extended-release, dividing doses differently, or trying a different diabetes medicine can help. Newer drugs add benefits like weight loss or heart protection, so talk to your doctor about the right combo for you.
