Metformin Linked to Increased Risk of Bladder Cancer

Metformin, the well-known drug often prescribed for Type 2 diabetes, was recalled by the US Food and Drug Administration (FDA) on May 28, after testing found high levels of the carcinogen N-nitrosodimethylamine (NDMA). The FDA is recalling all extended-release products containing metformin hydrochloride, including under the brand names Riomet, Glumetza, Fortamet, and Glucophage XR.

How is Bladder Cancer Linked to Metformin?

FDA agency tests revealed that samples of metformin contained NDMA amounts significantly higher than the recommended daily limit. NDMA can be produced both naturally and artificially and was formerly used to make rocket fuel and plastics. It is not currently produced or commercially used in the US, except for in laboratory research. In fact, its main use today is to induce tumor growth in experimental animals, and it has been known as a cancer risk for decades. An article from the 1970s stated that “NDMA has caused cancer in nearly every laboratory animal tested so far.”

NDMA can be found in pharmaceuticals for a number of reasons. The FDA has found in the past that NDMA formation has occurred due to the manufacturing, packaging, and storage conditions of the drug, as well as the chemical structure of the drug itself. Some research has even found that NDMA can be formed in the human body after ingestion.

People with Type 2 diabetes already have an approximately 40% increased chance of developing bladder cancer, but the NDMA levels in Metformin can further extend that risk. Various studies throughout the world have shown that there is a specific link between nitrosamines like NDMA and bladder cancer.

Though Metformin has been approved as a safe drug to control high blood sugar since 1994, recent tests have shown that there are levels of NDMA that exceed the amount allowed by the law.
