What is Glucophage (Metformin)?
Glucophage, also known by its generic name metformin, is a medication commonly used to help manage type 2 diabetes. If you have type 2 diabetes, your body either doesn’t produce enough insulin or can’t use it properly. Insulin is a hormone that helps control your blood sugar levels.
Metformin works by:
- Reducing the amount of sugar your liver releases: Your liver makes and releases glucose (a type of sugar) into your blood. Metformin helps to reduce this release.
- Improving your body’s response to insulin: It helps your body use insulin more effectively, which helps lower your blood sugar levels.
- Decreasing sugar absorption: It also reduces the amount of sugar absorbed from the food you eat.
People usually take Glucophage with meals to help reduce any stomach-related side effects. Some common side effects include nausea, diarrhea, and stomach upset, but these often improve over time.
What are Glucophage used for?
Glucophage (metformin) is mainly used to help people with type 2 diabetes manage their blood sugar levels. Here are the key uses:
- Managing Type 2 Diabetes: The primary use of this drug is to help lower high blood sugar levels in people with type 2 diabetes. It works by reducing the amount of sugar your liver makes, helping your body use insulin better, and decreasing the amount of sugar absorbed from food.
- Preventing Diabetes Complications: By keeping blood sugar levels in check, it helps prevent complications associated with diabetes, such as nerve damage, kidney problems, and heart disease.
- Weight Management: Some doctors may prescribe this medicine to help with weight loss in people who are overweight and have type 2 diabetes or prediabetes. It helps by improving insulin sensitivity, which can make it easier to lose weight.
- Polycystic Ovary Syndrome (PCOS): In some cases, it is used to treat PCOS, a condition that affects women and can cause irregular periods, infertility, and other health issues. Metformin can help regulate menstrual cycles and improve insulin resistance, which is often linked to PCOS.
What is the best time to take Glucophage?
The best time to take Glucophage (metformin) can depend on your specific needs and your doctor’s advice. Here are some general guidelines:
- With Meals: This medicine is often taken with meals to reduce the chances of stomach upset. It can help prevent nausea, diarrhea, and other digestive side effects when taken with food.

- Evening Dose: Many people are advised to take Glucophage in the evening, especially if they are on a once-daily dose. Taking it at night can be particularly beneficial because it helps control blood sugar levels during sleep, when the liver is most active in producing glucose.
