A medicine used to treat diabetes will reduce the risk of contracting Covid long after contracting Covid. This was shown by a study published this Friday, June 9, in the journal Lancet Infectious Diseases. This is metformin, a common drug used to treat type 2 diabetes.
The trial ran from December 2020 to January 2022 and involved 1,126 overweight or obese people in the United States. After testing positive for Covid, half of the patients were given metformin and the other half were given a placebo. Ten months later, 35 participants who took metformin were diagnosed with long-term Covid, compared with 58 people who took placebo. Thus, the drug will reduce the risk by 40%.
A step forward against lingering Covid, a disease that affects 10% of positive Covid cases
“Our data show that metformin reduces the amount of SARS-CoV-2 virus.” in patients, study author Carolyn Bramante, a researcher at the University of Minnesota, told AFP. The drug, however, has not been tested on patients who have had Covid for a long time. Therefore, it can only be used to prevent disease, and not to treat it.
Metformin has the advantage of being inexpensive and widely available because it is commonly used in diabetes.

The researchers also looked at ivermectin, a drug that has often been the subject of misinformation, as well as fluvoxamine, an antidepressant. The study shows that neither of these two treatments are effective in preventing lingering Covid.
According to the World Health Organization, one in ten people who test positive for Covid develop long-term Covid.
