1 Efficacy and Safety of Hydroxychloroquine for COVID-19 Post-Exposure Prophylaxis of Healthcare Workers in the Philippine General Hospital and UP Manila National Institutes of Health: A Randomized, Double-blind, Placebo-controlled Trial

This COVID-19 pandemic warrants urgent strategies to protect people at high risk of infection, particularly the healthcare workers. Secondary prevention through post-exposure prophylaxis (PEP) and early treatment of infection are needed to prevent severe cases and cut secondary transmission. Hydroxycholoroquine (HCQ) is an inexpensive anti-malarial drug with immunomodulatory effects that are currently used as an off-label treatment for symptomatic COVID-19 patients. In vitro studies have shown that it can efficiently inhibit SARS-CoV-2 infection and has potential as a post-exposure prophylaxis drug.
