For some patients, improved insulin sensitivity may also support modest weight loss over time.

This medication can help you:

  • Reduce high blood sugar
  • Improve insulin sensitivity
  • Support long-term metabolic health

Metformin ER is sometimes prescribed off-label for conditions such as polycystic ovary syndrome (PCOS) or to support weight management in patients with obesity.

About metformin ER prescriptions

Medically reviewed by:Dr. Allison Edwards, MD

Some people may experience modest weight loss while taking metformin ER, though it’s not the primary purpose of the drug. Metformin ER works by improving your body’s sensitivity to insulin and reducing the amount of glucose produced by the liver. For individuals with insulin resistance, common in type 2 diabetes or PCOS, this can lead to gradual weight loss.

Metformin ER is not a weight loss medication, so results vary. If you’re looking for additional support, consider exploring Sesame’s online weight loss program to help reach your goals safely and effectively.

Tell your provider about any kidney, liver, heart, or metabolic conditions, as well as all medicines or supplements you take. Possible drug interactions include other diabetes medications, diuretics, corticosteroids, blood pressure medications, thyroid medications, and seizure medications. Taking metformin ER with berberine may increase the risk of low blood sugar, as both can lower blood glucose levels.

Metformin ER may not be safe for people over 65 with reduced kidney function or those with severe cardiovascular disease. Avoid alcohol while on metformin ER. If you are pregnant, planning to become pregnant, or breastfeeding, discuss the potential risks and benefits of using metformin ER with your healthcare provider.

Store metformin ER according to the instructions provided by your healthcare provider or pharmacist. Keep it at room temperature, away from light and moisture. Ensure the container is tightly closed and out of reach of children.

Do not use expired medication or medications that appear damaged or discolored. If you have any questions about storage, consult your healthcare provider or pharmacist for guidance.

Metformin ER is usually taken once daily with a meal, often in the evening. As with any diabetes treatment, follow your provider’s dosage instructions.

If you miss a dose of metformin ER, take it as soon as you remember, unless it is close to the time for your next scheduled dose. In that case, skip the missed dose and continue your regular dosing schedule. Do not double the dose to make up for a missed one. Take metformin ER around the same time every day to maintain an even level of medication in your body.

Do not suddenly stop taking metformin ER, as this can cause your blood sugar levels to become uncontrolled. Your healthcare provider will provide guidance if you need to stop taking it.

Taking more metformin than prescribed can increase the risk of serious side effects, including low blood sugar and lactic acidosis, a rare but potentially life-threatening condition. Early signs of lactic acidosis may include nausea, vomiting, fatigue, rapid or shallow breathing, and muscle cramping.

If you suspect an overdose, seek medical attention immediately or call your local poison control center at 1-800-222-1222. Always take metformin exactly as prescribed, and never take extra doses to try to improve results.

Metformin ER is not available over the counter. You must have a prescription from a licensed healthcare provider to obtain it. Providers on Sesame can write a new prescription or refill an existing one through a telehealth visit. Depending on your location, you may be able to pick up your metformin ER the same day at a local pharmacy.

You can buy metformin online. Licensed Sesame providers can review your health history, current medications, and treatment goals during a convenient video visit.

If metformin ER is appropriate for you, your provider can send a prescription directly to a nearby pharmacy for pick-up. All prescriptions are at the discretion of the provider, and Sesame does not prescribe controlled substances.

Several other medications can be used to manage type 2 diabetes, depending on your blood sugar levels and overall health. Some patients take combination medications such as glyburide-metformin or sitagliptin-metformin (generic for Janumet), which combine metformin with other diabetes drugs to improve glucose control.

Other options include sulfonylureas such as glipizide, SGLT2 inhibitors like empagliflozin, GLP-1 receptor agonists such as semaglutide, or different types of insulin. A healthcare provider can help determine which treatment is most appropriate based on your health history and blood sugar goals.
