Since WHO declared the COVID-19 as a pandemic,1 2 healthcare systems all over the world have focused their efforts on limiting the spread of SARS-CoV-2, and despite the ceaseless development of strategies to struggle with the impact of COVID-19, there is no sign of let-up. And the stress and overburden elicited by the pandemic—especially in vulnerable or marginalised populations—remain unstoppable, while the possibility of massive vaccination gives hope for a respite.3 4 Beyond public health interventions, several drugs have been considered for the treatment of SARS-CoV-2 infection,5 which triggers severe respiratory symptoms and critical illness in approximately 5%–20% of patients, with intensive care requirements and high mortality.6–10 In this article, we appraise and debate about the available evidence regarding the role of ivermectin for COVID-19.
Randomised Evaluation of COVID-19 Therapy (RECOVERY) trial results have had a critical role establishing the most useful pharmacological interventions in COVID-19 critical care, such as dexamethasone.11 However, despite the development of new therapies and the attempts for implementing repurposed drugs (because of their potential immunomodulator or antiviral effects), no reliable specific therapy has been identified yet. Azithromycin, chloroquine and hydroxychloroquine are some of those drugs, whose adverse effects and/or concerns about efficacy on COVID-19 treatment12 have determined its deimplementation by different agencies and regulatory authorities.13–15 And despite the wide dissemination of these recommendations, paradoxically, its adherence in both high-income, and middle-income and low-income countries has been hindered not only by the COVID-19 social media infodemic, but also by authorities.16
