Are corticosteroids (anti-inflammatory medicines) given orally or by injection an effective treatment for people with COVID-19?
Cochrane has produced a series of reviews relevant to the COVID-19 pandemic and is keeping these up-to-date in light of new evidence. In November 2022, we published the second version of a living systematic review on systemic corticosteroids and, in this podcast, the first authors, Mirko Griesel of the University of Leipzig Medical Center and Carina Wagner of the University Hospital in Cologne in Germany, talk about the evidence they ’ve found and the potential effects of these drugs.
