Metformin has been shown to reduce the risk of Long COVID

Summary

Rachel Hall-Clifford took metformin, titrating up slowly to minimize GI side effects, and continued taking it for several months after her infection, though the article does not give an exact dose. She developed Long COVID in 2022 and later had a SARS-CoV-2 reinfection, and her symptoms got much better during the months she was on metformin, though she says she can't directly attribute the improvement to the drug alone, calling it "part of the toolkit." The article gives no information about whether the improvement held, faded, or required ongoing dosing after she stopped.
