What’s been said?
The medicines regulator said: "During testing prior to batch release, levels of the impurity NDMA in batch number 0LL0018 of metformin oral solution were found to be within acceptable limits.
"However routine monitoring of the batch while on the market showed that levels of NDMA were no longer acceptable at nine months."
Dr Alison Cave, MHRA chief safety officer, said: "Patient safety is at the heart of everything we do.
"This recall of one batch of metformin oral solution is a precautionary measure to prevent further exposure to the nitrosamine impurity.
