Common, inexpensive diabetes drug could cut long COVID risk, study finds – CBC

Metformin reduced long COVID incidence among infected patients by 41 per cent

A well-known, inexpensive diabetes drug appears to cut the risk of developing long COVID, hopeful-but-early new research suggests.

The study, published Thursday in the peer-reviewed journal Lancet Infectious Diseases, found outpatient treatment with the drug metformin — a common treatment for Type 2 diabetes — reduced long COVID incidence among infected patients by 41 per cent.
