How much does Metformin cost without insurance?

Prescription prices vary by different factors, such as quantity and pharmacy location. On average, the price of Metformin oral tablets for uninsured customers is $138.22 for 180, 1000mg tablets of Metformin. Metformin is considered an inexpensive generic medication that can typically be found at affordable prices. 

How much does Metformin cost with insurance?

Your Metformin copay amount may vary depending on your insurance company and the plan’s formulary. The price of Metformin with insurance can also vary depending on the dosage, formulation, and quantity prescribed. You may have a higher out-of-pocket cost if you’re in the deductible stage of health insurance coverage. After meeting your plan’s deductible, you may have a copay or coinsurance after sharing the costs with your insurance provider.

With SingleCare, generic Metformin costs $9.92 for 180, 1000mg tablets, which may be lower than your insurance copay. Consult with your pharmacist to determine the best option. Check the SingleCare website to take advantage of prescription savings right away at participating pharmacies.

Does Medicare cover Metformin?

Metformin costs with Medicare will vary by plan, prescription, and coverage stage. Metformin is generally covered by Medicare Advantage and Medicare Part D prescription drug plans. Consult your plan’s provider or local pharmacist to determine your Metformin cost with your Medicare prescription plan. You can use a prescription discount card, such as the one offered by SingleCare, in place of your Medicare coverage if your cost with Medicare is too high.

Does Medicaid cover Metformin?

Medicaid plan structure and coverage options vary by state. Typically, your Medicaid plan will have a formulary of pre-approved drugs. It is reasonable to expect to have Metformin on the formulary in at least some dosages and formulations. If Metformin is not on your Medicaid plan or your cost responsibility seems too high, you can ask the pharmacy to use a SingleCare coupon instead of Medicaid to provide you with the lowest possible price without coverage. 

What is the brand name for Metformin?

Metformin is a generic prescription drug produced by various manufacturers, including Mylan, Sun, and Zydus Pharmaceuticals. There is also a generic extended-release version of Metformin. Brand-name versions, such as Glucophage, Glucophage XR, Glumetza, and Fortamet, are no longer available in the United States, but their respective generics are. Your cost is very much dependent on which formulation is prescribed for you.

  • Medicare Extra Help or Medicaid: These programs can help cover your drug costs based on income eligibility. Check with your local entity for more details and to apply.

  • FSA or HSA accounts: Your employer may offer opportunities to put funds into accounts for healthcare costs. This can help you budget these costs, and your contribution may be tax-deductible. Some employers even match these funds, so take advantage of what is offered to you.

Is there a cheaper alternative to Metformin?

There are several Metformin alternatives available to help control blood sugar levels, but whether they are more cost-effective depends on your coverage. These drugs include: 

  • SGLT-2 inhibitors, such as Jardiance (empagliflozin), Invokana (canagliflozin), and Farxiga (dapagliflozin)

  • GLP-1 receptor agonists, such as Byetta (exenatide), Victoza (liraglutide), Ozempic (semaglutide), and Mounjaro (tirzepatide), DPP-4 inhibitors, such as Januvia (sitagliptin), Onglyza (saxagliptin), and Tradjenta (linagliptin)

  • Sulfonylureas, such as Glucotrol (glipizide), Diabeta (glyburide), and Amaryl (glimepiride)

  • Thiazolidinediones, such as Actos (pioglitazone) 

  • Insulin may also be recommended to help control blood sugar levels. 

The best Metformin alternative will depend on your overall condition, potential side effects, and other factors. Consult your healthcare provider for more information if you want to change your treatment plan.
