Hydroxychloroquine-azithromycin combo may be potentially lethal: Study

Hydroxychloroquine and azithromycin, which have been been proposed for treatment of COVID-19 patients, are a potentially lethal combination, and may have a serious impact on the cardiovascular system, according to a study.
The researchers, including those from Vanderbilt University and Stanford University in the US, carried out an observational, retrospective meta-analysis of a WHO database encompassing over 21 million adverse event case reports.
The reports span across all medication classes from over 130 countries between November 14, 1967, and March 1, 2020 — mainly before the COVID-19 pandemic.
