RESUMEN
While antidepressant drugs (ADs) have shown some efficacy in treatment of COVID-19, their preventative potential remains unexplored. To investigate association between AD and COVID-19 incidence in the community, we analysed data from community-living, non-hospitalized adults admitted to inpatient care of the South London&Maudsley (SLaM) NHS Foundation Trust during the 1st wave of COVID-19 pandemic in the UK. Prescription of ADs within the period of 1 to 3 months before admission was associated with an approximately 40% decrease in positive COVID-19 test results when adjusted for socioeconomic parameters and physical health. This association was specifically observed for ADs of the Selective Serotonin Reuptake Inhibitor (SSRI) class. These results suggest that ADs, specifically SSRIs, may help prevent COVID-19 infection in the community. Definitive determination of AD preventative potential warrants prospective studies in the wider general population.
