The clinical trial, which began in 2020, analyzed more than 1,300 patients in Brazil who were infected with the coronavirus. Half were given ivermectin and half a placebo in the randomized, double-blind study, meaning neither doctors nor trial participants knew what a patient received. In double-blind RCT, ivermectin that was administered within 7 days after Covid-19 symptom onset was shown not to be of any clinical benefit. Preliminary experiments suggested at the time that ivermectin might block the coronavirus, and some doctors began prescribing it despite FDA warnings. Some people began turning to farm supply stores to buy dosages of the drug used for livestock, overdosing on medication meant for much larger creatures.
