I would like to clarify multiple concerns regarding the use of Metformin.
The recent recall of Metformin XR (extended-release) does not have any effect on those using Metformin IR (immediate-release).
Let me explain the difference.
Extended-release medication is prescribed to patients when patients are sensitive to the medication or when they need the medication to be released gradually over 24 hours
The only concern is that the presence of NDMA (N-Nitrosodimethylamine) in XR Metformin exceeds the acceptable limit in some manufacturers.
If you or a family member is on Metformin XR, DO NOT STOP taking the medication.
If you have not already been contacted by your pharmacy, check with them to see if your medication is on the recall list - they will provide you with a different, approved manufacturer.
Please do not switch to Metformin IR without consulting with your prescribing doctor.
If you have any additional questions regarding your manufacturer, you can check the official FDA website for updates.
Metformin has been approved for the treatment of Diabetes, Prediabetes, PCOS, Insulin resistance/Metabolic syndrome. In fact, Metformin is the oldest, most effective, and least expensive medication used for the treatment of diabetes. Metformin works by reducing glucose production from the liver (from glycogen stores).
Gastrointestinal side effects, such as bloating and diarrhea, can be diminished with the use of ER formulation.
If you are still concerned about the medication and would like to switch to a different medication, please discuss your specific concerns at your upcoming appointment.
