How Much Does Metformin Cost Without Insurance?

The cash price for 500 mg oral metformin tablets without insurance is typically around $13-$22 for a supply of 100 tablets, depending on your pharmacy.

What Is Metformin Used For?

Metformin is a prescription medication used to treat type 2 diabetes. It does not help patients who have insulin-dependent or type 1 diabetes because they don’t produce insulin from their pancreas gland. Metformin is generally considered a first-line treatment for type 2 diabetes. This means it’s typically the first medication medical providers prescribe for this condition. 

Metformin works by controlling blood sugar levels. It does this by reducing the amount of glucose produced by the liver and increasing the sensitivity of cells to insulin. It also reduces the amount of sugar the intestines absorb. In addition, metformin can also help lower the risk of complications such as heart disease and stroke. 

Metformin is available in both tablet and liquid form. It’s typically taken with meals to help reduce side effects such as nausea and diarrhea. Take metformin exactly as your medical provider instructs. Sometimes, they may need to change your dose depending on your blood sugar levels. 

How to Get Metformin

If you have a prescription for metformin, you can fill it at your local pharmacy. You can also purchase metformin online from an accredited pharmacy. However, you will need a prescription from your medical provider to get metformin online.

Manufacturer coupons and patient assistance programs are also available for metformin. These programs can help you save money on your medication costs. Contact the manufacturer of your medication to inquire about discounts and coupons, or contact a patient assistance program for help.

Finally, you can check online for discounts. There are often websites that offer coupons or discounts on prescription drugs. With a bit of research, you should be able to find a way to get a discount on the prescription medications you need.
