Frequently Asked Questions

Who first described metformin, and when did it become a medicine?

First described in 1922 by Emil Werner and James Bell; introduced as a medication in France in 1957.

Metformin was first described in the scientific literature in 1922 by Emil Werner and James Bell. French physician Jean Sterne began the study in humans in the 1950s. It was introduced as a medication in France in 1957.

Why is metformin restricted in people with severe kidney disease?

Because of the rare but serious risk of lactic acidosis, which seems related to impaired kidney or liver function.

The most serious potential adverse effect of metformin is lactic acidosis; this complication is rare, and seems to be related to impaired liver or kidney function. Metformin is not approved for use in those with severe kidney disease, but may still be used at lower doses in those with kidney problems. Because of concerns about potential lactic acidosis, the US Food and Drug Administration recommends avoiding its use in more severe chronic kidney disease, below an eGFR cutoff of 30 mL/minute/1.73 m2.
