Effects of MetforminThere have been several studies documenting the effects of metformin for type 2 diabetes. In these studies, the drug has been shown to decrease fasting blood sugar and to decrease hemoglobin A1c (HbA1c). HbA1c is a test used to measure long-term blood sugar control in people with diabetes. Normal HbA1c levels are usually less than 6 percent in people without diabetes; people with diabetes usually have higher HbA1c results.
When and How Do I Take It?Some general considerations for when and how to take the medication include:
- Metformin tablets should be taken by mouth, usually one to three times daily. The long-acting form, metformin ER, should be taken once daily with your evening meal.
- The medication should be taken with food to reduce stomach upset.
- The long-acting form (metformin ER) should be swallowed whole and should not be broken or crushed.
- It should be taken at the same time(s) each day to maintain an even level of the drug in your blood.
- For the medication to work properly, it must be taken as prescribed. It will not work if you stop taking it.
