On May 28, 2020, the U.S. Food and Drug Administration (FDA) asked five makers of metformin extended-release (ER) tablets to remove their products from the market.

June 30, 2020  

There are other makers of metformin ER that are not being asked to remove their product from the market at this time.  This step was taken when an impurity that may cause health risks was found in these drugs.

What do you need to do?

  • Do not stop taking the drug on your own. The FDA recommends that you should keep taking your medication until you talk with you provider. The risk of harm to your health may be higher if you stop taking your drug without switching to another treatment.
  • Please call your pharmacist to see if they filled your prescription with one of the impacted products. Your pharmacist will be able to tell you if they filled your prescription with medicine from one of the drug makers being asked to remove their product from the market. The pharmacist will let you know if you need to contact your healthcare provider for a new prescription. If needed, call your healthcare provider to obtain a new prescription for another medication so you can keep treating your health issue without any breaks. Please note: Watch for updates from the FDA and your local pharmacy. More drug makers may have to remove their products from the market as more testing and information becomes available.
  • In light of COVID-19, the FDA recommends that you do not take your medicines to a drug take-back site. Instead, follow the disposal steps in the medication guide or package insert. Or go to Follow the FDA steps to dispose of drugs safely at home.
