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.
Roughly six per cent of those taking metformin went on to develop the condition, compared to close to 11 per cent of those in the placebo group. Participants on metformin were also less likely to be hospitalized roughly a month after infection by SARS-CoV-2, the virus that causes COVID-19.
"Metformin has clinical benefits when used as outpatient treatment for COVID-19 and is globally available, low-cost and safe," wrote the research team.
Lead author Dr. Carolyn Bramante, a physician-scientist with the University of Minnesota in Minneapolis, told CBC News that the effect was even larger when metformin was given quickly
