Diabetes drugs being tested for carcinogens

Drugs commonly used to treat diabetes are being tested for unsafe levels of carcinogens by the FDA.

The FDA is looking into the drug, metformin, to test for nitrosamine impurity, N-nitrosodimethylamine (NDMA)––a probable human carcinogen that could cause cancer. NDMA was also recently found in trace amounts in Zantac, a heartburn drug, leading to a recall of the medication.

The FDA’s investigation into metformin, which helps control high blood sugar in patients with diabetes, has yet to determine if there are unsafe levels of NDMA.

“The agency is in the beginning stages of testing metformin; however, the agency has not confirmed if NDMA in metformin is above the acceptable daily intake (ADI) limit of 96 nanograms in the U.S.,” reads a statement by FDA spokesman Jeremy Kah. "These investigations take time. The FDA will communicate further information when we understand more of the situation and of what, if any, actions health care professionals and patients should take."

In addition, the agency stated those with diabetes who take metformin should not stop taking their medications as prescribed.

The investigation comes after some cardiology experts stated the Zantac recall and findings were likely just the “tip of the iceberg” for recalls over carcinogenic impurities.

A string of executive orders from the White House created serious concerns among radiologists and other healthcare providers throughout the United States. The American College of Radiology issued a statement to help guide its members through the chaos. 

Bridgefield Capital, founded in 2015, has previously invested in such popular brands as Cirque Du Soleil, Del Monte and Quiksilver. This transaction is expected to be completed in the second half of 2025. 

Given the precarious excitement of the moment—or is it exciting precarity?—policymakers and healthcare leaders must set directives guiding not only what to do with AI but also when to do it.
