Millions of people across the globe are suffering from one or the other type of diabetes. Besides, Metformin is one of the most well-known medication for treating Type 2 diabetes. But, have you ever thought of the dark side of this diabetes-treating drug. Scientists surmise Metformin contains probable cancer-causing elements. Thus, the US Food and Drug Association is probing the medicine, whether it has carcinogenic ingredients or not. Well, it is not the first drug that consists of cancer-causing compounds. Since the past one-and-a-half year, a wide array of medicines has revealed the existence of cancer-causing chemicals within them. The list includes Zantac (ranitidine), angiotensin II receptor blockers, etc.
Researchers have discovered those drugs contain small quantities of genotoxic substances or nitrosamines like NDMA. According to the FDA, more than adequate introduction to such chemicals for an extended period of time may raise the risk of cancer. Currently, the FDA is probing whether metformin in the US contains NDMA. As per Janet Woodcock, M.D., director of the FDA Center for Drug Evaluation and Research, researchers have found a small amount of NDMA in metformin sold in other countries. Thus the FDA is seeking whether the medicine in the US goes above the suitable daily limit of 96 mg. She noted the amount of NDMA in medications aboard is within the limit that naturally exists in some foods or water.
Woodcock noted; still, officials in some other countries are recalling some metformin medicines. She also said, for now, none of the metformin recalls are influencing the U.S. market. Woodcock said the FDA would also function with companies to test samples of metformin present across the U.S. market. Even more, the federal agency will recall medications if essential, or it founds excessive levels of NDMA. Currently, the FDA is requesting people using metformin not to stop the consumption of the drug without the advice of health experts.
