Ivermectin for COVID-19
4th treatment shown to reduce risk in August 2020, now with p < 0.00000000001 from 105 studies, recognized in 23 countries.
No treatment is 100% effective. Protocols combine treatments.
5,100+ studies for 110 treatments. c19ivm.org
Safety study concluding that ivermectin was generally well tolerated, with no indication of associated CNS toxicity for doses up to 10 times the highest FDA-approved dose. Adverse effects were similar between ivermectin and placebo and did not increase with dose. Authors also show that the plasma concentration is much higher when taken with food (geometric mean AUC 2.6 times higher).

I vermectin is a derivative of the avermectins, a family of macrocyclic lactones produced by the filamentous bacterium Streptomyces avermitilis. It is a highly effective antihelmintic agent used in animals and humans. Ivermectin was first approved for human use in 1987 and is donated by Merck & Co., Inc., as Mectizan ® for the treatment of onchocerciasis and, more recently, lymphatic filariasis in Africa and Latin America.
