    Default Testing Lab Challenges FDA Findings: Carcinogens In Metformin

    Eric Palmer
    March 2 2020

    As questions about suspected carcinogens in drugs continue to roil the supply chain, the FDA last month said its testing of metformin did not find any with unacceptably high levels of NDMA. But testing laboratory Valisure has challenged those findings in a new Public Citizen petition, saying it discovered problems in 42% of the batches it checked. It contends the situation is likely to get worse as the COVID-19 outbreaks wreak havoc on supply chains.

    I am skeptical about all prescription drugs, and had my doctor's approval to discontinue metformin at my six month diabetes review. All prescription drugs have potential side effects, and clearly there are purity concerns as well.

    If I understood correctly, the problem seems to be worse with the "generic" form of metformin. Generic drug forms are generally cheaper, mainly becuase the patents have expired. I believe they're cheaper because of the ingredients used too. As I understand it, generic drugs must contain all the "acitve" ingredients of the parent drug, but can contain different "inactive" ingredients. It's the "inactive" stuff that concerns me becuase that's the stuff the officials typically don't pay attention to.

    Good points, often overlooked.

    Studies have indicated that different "inactive" ingredients, such as coloring or flavoring, can affect how the active ingredients are more or less absorbed. People can also have allergic reactions to inactive ingredients that may be wheat based, etc.
