The Impact of Metformin and Self-Treatment on Long COVID and Antiviral Sales.

Metformin, a cheap diabetes drug, could potentially impact sales of Pfizer's COVID-19 antiviral pill, Paxlovid, due to its potential effectiveness in treating Long COVID. Research indicates that metformin and Paxlovid could have synergistic effects, and metformin may also encourage more individuals to take Paxlovid. While the evidence for metformin in COVID-19 is promising, more research is needed. Pfizer has warned of a decline in Paxlovid sales in 2023, but remains optimistic about the drug's future beyond that year.
