I was prescribed by my doctor to take Metformin extended release 500 mg. Recently I found out it was on recall due to cancer enhancing chemicals through the NDC.

The pharmacist insisted I'd be fine; however, due to my concern he claims he would give me another brand of metformin (still 500mg) that is not on the recall list.

The Walmart label does NOT show the NDC so I cannot verify.

I'd like to see how I can go about taking this medication peacefully. How can I check and see if these are indeed safe?
