A large analysis of health records from 87 health care centers across the United States found that people taking a class of antidepressants called selective serotonin reuptake inhibitors (SSRIs), particularly fluoxetine, were significantly less likely to die of COVID-19 than a matched control group.
The results add to a body of evidence indicating that SSRIs may have beneficial effects against the worst symptoms of COVID-19, although large randomized clinical trials are needed to prove this.
The UCSF-Stanford research team analyzed electronic health records from the Cerner Real World COVID-19 de-identified database, which had information from almost 500,000 patients across the U.S. This included 83,584 adult patients diagnosed with COVID-19 between January and September 2020. Of those, 3,401 patients were prescribed SSRIs.
The large size of the dataset enabled researchers to compare the outcomes of patients with COVID-19 on SSRIs to a matched set of patients with COVID-19 who were not taking them, thus teasing out the effects of age, sex, race, ethnicity, and comorbidities associated with severe COVID-19, such as diabetes and heart disease, as well as the other medications the patients were taking.
The results showed that patients taking fluoxetine were 28 percent less likely to die; those taking either fluoxetine or another SSRI called fluvoxamine were 26 percent less likely to die; and the entire group of patients taking any kind of SSRI was 8 percent less likely to die than the matched patient controls.
Though the effects are smaller than those found in recent clinical trials of new antivirals developed by Pfizer and Merck, the researchers said more treatment options are still needed to help bring the pandemic to an end. JAMA Network Open
