The FDA has asked five drugmakers to voluntarily recall their metformin products after it found unacceptable levels of a carcinogen in the drug, The Wall Street Journal reported.

The agency said May 28 that after months of testing, it found unacceptable levels of N-nitrosodimethylamine, or NDMA, a cancer-causing chemical when ingested at high levels, in extended-release versions of metformin.
