Metformin

Attorneys Representing Consumers Injured by Dangerous Drugs

Pharmacy Medicament Metformin is a commonly prescribed medication that is used to control high blood sugar levels in patients with type 2 diabetes. Sometimes it is prescribed with insulin medications. Metformin is sold under various names, including Glucophage, Fortamet, Glumetza, and Riomet. Since late 2019, the FDA has been investigating whether there is a carcinogenic impurity in metformin. If you believe that you may have been harmed by a metformin drug product, you should consult the metformin injury lawyers at Moll Law Group.

Impurities in Metformin

Metformin is a prescription drug taken daily to keep diabetes. It comes in extended release formulas. In late 2019, the FDA posted lab results that revealed N-nitrosodimethylamine (NDMA) levels in certain metformin products. The FDA determined that the levels were not detectable or were low, and none went over the acceptable daily intake for carcinogenic impurity. However, the FDA continued to monitor NDMA in metformin.

Early in July 2020, a private laboratory reported that NDMA levels were above the acceptable intake limit in 16 of 38 metformin products that they tested. The same 38 samples were analyzed by the FDA, but they observed lower levels of NDMA.

Metformin Recall

Later in July 2020, several companies voluntarily recalled extended release metformin based on the possibility that these drugs could contain NDMA above the acceptable intake level. In August, the FDA alerted patients and doctors that Bayshore was recalling two lots of extended release metformin. These lots were discovered to contain an impurity that exceeded the acceptable intake limit. A recalled metformin list was published. It contained the following products:

  • Amneal Pharmaceuticals: Metformin HCl 500 mg Extended Release Tablets
  • Amneal Pharmaceuticals: Metformin HCl 750 mg Extended Release Tablets
  • Apotex Corp: Metformin HCl 500 mg Extended Release Tablets
  • AVKARE Inc. (Amneal): Metformin HCl 500 mg Extended Release Tablets
  • AVKARE Inc. (Amneal): Metformin HCl 750 mg Extended Release Tablets
  • Bayshore Pharmaceuticals: Metformin HCl 500 mg Extended Release Tablets
  • Bayshore Pharmaceuticals: Metformin HCl 750 mg Extended Release Tablets
  • Granules Pharmaceuticals: Metformin HCl 750 mg Extended Release Tablets
  • Lupin Pharmaceuticals: Metformin HCl 500 mg Extended Release Tablets
  • Lupin Pharmaceuticals: Metformin HCl 1000 mg Extended Release Tablets
  • Marksans Pharma Limited: Metformin HCl 500 mg Extended Release Tablets
  • PD-Rx Pharmaceuticals (Amneal): Metformin HCl 500 mg Extended Release Tablets
  • PD-Rx Pharmaceuticals (Marksans): Metformin HCl 500 mg Extended Release Tablets
  • Teva Pharmaceuticals: Metformin HCl 500 mg Extended Release Tablets
  • Teva Pharmaceuticals: Metformin HCl 750 mg Extended Release Tablets

Our metformin injury attorneys know that NDMA impurities can increase the risk of cancer if people are exposed to them at higher-than-acceptable levels over an extended period. However, the FDA does not believe that shorter-term exposure at levels above the acceptable intake limit would result in an increased cancer risk. Accordingly, patients taking extended release metformin that has been recalled are supposed to discuss the risk with their doctors and keep taking metformin until a doctor gives them a different treatment option or replacement. It may be dangerous for a patient with type 2 diabetes to stop taking metformin without discussing it with their health care provider.

In its testing of extended release metformin, the FDA found no NDMA in many samples. The agency determined that the NDMA did not come from an active pharmaceutical ingredient in the drug. The FDA believes that it is possible to make metformin without these impurities, but the root cause of the NDMA impurity is the subject of an ongoing investigation. Our injury lawyers will follow the metformin investigation closely. The agency also has issued a reminder to manufacturers that they have an obligation to develop appropriate ways of detecting impurities, and when new or higher degrees of impurities are found, manufacturers should evaluate them. Manufacturers should make sure that pharmaceuticals are safe for patients.

Suing a Manufacturer for Compensation

If you were harmed by metformin, you may be able to recover compensation through a product liability lawsuit. Generally, pharmaceuticals can be defective in terms of their design, marketing, or manufacturing. When an impurity like NDMA is present in some of the drugs but not others, a manufacturing defect may exist. This means that the danger may result from an error in how the drug was made.

However, it may also be possible to allege design or marketing flaws in a dangerous drug. Design flaws are errors that exist in every iteration of the drug. Marketing flaws most often involve failures to warn of the risks associated with the drug, such as a heightened risk of cancer.

If we can establish liability for harm arising out of metformin use, we may be able to recover compensation on your behalf. This can include both economic losses, such as medical bills and lost income, and non-economic losses, such as pain and suffering and mental anguish.
