Used to manage symptoms of Type 2 Diabetes, metformin is one of the most successful drugs in the United States. It was first approved by the United States Food & Drug Administration (FDA) in 1994, and by 2020, it was being prescribed to more than 78 million people, making it the fourth most-prescribed drug in the country. 

Metformin has long been considered safe and reliable; it’s even on the World Health Organization’s (WHO) 2019 “Essential Medications” list. But that may be changing. 

Following an alert by independent pharmacy Valisure and investigations by the FDA, there is a growing concern that metformin tablets may be contaminated by NDMA, a potentially dangerous, cancer-causing chemical. The FDA has contacted metformin manufacturers whose  products may be contaminated to request that they voluntarily recall their medications. The FDA is also asking all metformin manufacturers to conduct further testing on their products. 

Metformin users who have cancer are now filing lawsuits against these manufacturers — their negligence may be the cause of users’ illnesses. If you or a loved one has taken metformin and was diagnosed with cancer, you may be eligible for compensation

Voluntary Recall List Growing 

According to the FDA, the following manufacturers have voluntarily recalled some or all of their metformin products:

  • Apotex
  • Amneal Pharmaceuticals
  • Teva Pharmaceuticals
  • Marksans Pharma 
  • Lupin Limited

How Was The Risk Discovered?

Valisure, an online pharmacy, was founded on the principle of testing drugs independently to ensure their quality. As such, they have been testing for NDMA in various popular medications for a while. In 2019, they were the first to blow the whistle about NDMA contamination in Zantac/Ranitidine

In March 2020, Valisure announced that it had found unacceptably high levels of NDMA contamination in metformin tablets. Following this announcement, the FDA found NDMA contamination in metformin as well. 

It is currently unclear whether some or all metformin batches from some or all manufacturers are contaminated by NDMA, or if they’re susceptible to future contamination due to time spent in storage.  

What Illnesses Are Linked To NDMA

NDMA is classified as a “probable human carcinogen” by the FDA — meaning it likely causes cancer in humans — and government regulators around the world and in the United States have set maximum safe contamination levels for humans ingesting this chemical. 

If ingested by humans, NDMA is believed to be linked to a wide range of illnesses and conditions, including:

  • Esophageal cancer 
  • Liver cancer
  • Stomach cancer (large and small intestines)
  • Bladder cancer 
  • Kidney cancer 
  • Prostate cancer 
  • Leukemia 
  • Pancreatic cancer 
  • Non-Hodgkin Lymphoma 
  • Colorectal cancer 
  • Testicular cancer

Am I Eligible For A Metformin Lawsuit?

If you or a loved one took metformin and has since been diagnosed with any of the above listed illnesses, you may be eligible for a lawsuit. If successful, you could win compensation for losses incurred due to the illness, including medical costs, lost wages, and damages for pain and suffering. 

Should I Stop Taking Metformin?

If you or a loved is taking metformin for diabetes, talk to your doctor before making any changes. Make sure to go over your options with your doctor and get a different prescription before you stop using metformin.
