Ivermectin for COVID-19
4th treatment shown to reduce risk in August 2020
*, now known with p < 0.00000000001 from 102 studies, recognized in 22 countries.
No treatment is 100% effective. Protocols combine complementary and synergistic treatments. * >10% efficacy in meta analysis with ≥3 clinical studies.
4,000+ studies for 60+ treatments.
Systematic review and meta analysis of trials within the first year of the pandemic, showing significantly faster viral clearance with ivermectin.
7 meta analyses show significant improvements with ivermectin for mortality Bryant, Hariyanto, Kory, Lawrie, Nardelli, Zein, hospitalization Schwartz, recovery Kory, and cases Kory.
Currently there are 102 ivermectin for COVID-19 studies, showing 49% lower mortality [35‑60%], 29% lower ventilation [12‑42%], 35% lower ICU admission [7‑54%], 34% lower hospitalization [20‑45%], and 81% fewer cases [71‑87%].

Ivermectin, an antiparasitic drug, has been repurposed for COVID-19 treatment during the SARS-CoV-2 pandemic. Although its antiviral efficacy was confirmed early in vitro and in preclinical studies, its clinical efficacy remained ambiguous. Our purpose was to assess the efficacy of ivermectin in terms of time to viral clearance based on the metaanalysis of available clinical trials at the closing date of the data search period, one year after the start of the pandemic. This meta-analysis was reported by following the PRISMA guidelines and by using the PICO format for formulating the question. The study protocol was registered on PROSPERO. Embase, MEDLINE (via PubMed), Cochrane Central Register of Controlled Trials (CENTRAL), bioRvix, and medRvix were searched for human studies of patients receiving ivermectin therapy with control groups. No language or publication status restrictions were applied. The search ended on 1/31/2021 exactly one year after WHO declared the public health emergency on novel coronavirus. The meta-analysis of three trials involving 382 patients revealed that the mean time to viral clearance was 5.74 days shorter in case of ivermectin treatment compared to the control groups [WMD = −5.74, 95% CI (−11.1, −0.39), p = 0.036]. Ivermectin has significantly reduced the time to viral clearance in mild to moderate COVID-19 diseases
