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.
Small 72 patient RCT of ivermectin and ivermectin + doxycycline showing faster recovery with ivermectin. The ivermectin + doxycycline group uses only a single dose of ivermectin vs. 5 daily doses for the ivermectin group. PCR testing was only done weekly after day 7, therefore hospitalization time may not match symptomatic recovery.
Ivermectin group: 12mg daily for 5 days
Ivermectin + doxycycline: 12mg ivermectin single dose, 200mg doxycycline + 100mg bid 4 days
This is the 8th of 49 COVID-19 RCTs for ivermectin, which collectively show efficacy with p=0.00000038.
This is the 24th of 102 COVID-19 controlled studies for ivermectin, which collectively show efficacy with p<0.0000000001 (1 in 560 quintillion).

Ivermectin, a US Food and Drug Administration-approved anti-parasitic agent, was found to inhibit severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) replication in vitro. A randomized, double-blind, placebo-controlled trial was conducted to determine the rapidity of viral clearance and safety of ivermectin among adult SARS-CoV-2 patients. The trial included 72 hospitalized patients in Dhaka, Bangladesh, who were assigned to one of three groups: oral ivermectin alone (12 mg once daily for 5 days), oral ivermectin in combination with doxycycline (12 mg ivermectin single dose and 200 mg doxycycline on day 1, followed by 100 mg every 12 h for the next 4 days), and a placebo control group. Clinical symptoms of fever, cough, and sore throat were comparable among the three groups. Virological clearance was earlier in the 5-day ivermectin treatment arm when compared to the placebo group (9.7 days vs 12.7 days; p = 0.02), but this was not the case for the ivermectin + doxycycline arm (11.5 days; p = 0.27). There were no severe adverse drug events recorded in the study. A 5-day course of ivermectin was found to be safe and effective in treating adult patients with mild COVID-19. Larger trials will be needed to confirm these preliminary findings.
Ethical review The trial was approved by the Institutional Review Board (Research Review Committee and Ethical Review Committee) of icddr,b and subsequently by the National Ethics Review Committee of Bangladesh Medical Research Council and Clinical Trial Advisory Committee of the Directorate General of Drug Administration, Government of Bangladesh.
