The FDA-approved Drug Ivermectin inhibits the replication of SARS-CoV-2

We know it as the least expensive way to treat head lice.  Trials start in 30 days but I would think people will start using it off-label.   I would if I had Covid-19.   Vets use it for ticks.  Also skin lotion.  Merck makes it and gives away million of doses for treating ‘river blindness’.

“Australian researchers have published a study showing a drug commonly used to treat parasite infections can also kill coronavirus in a laboratory setting in under 48 hours.

Researchers at Monash University in Melbourne, Australia have discovered that the antiparasitic drug Ivermectin can inhibit replication of SARS-CoV-2, the virus the causes COVID-19, according to a study published Friday in the journal Antiviral Research.

“Ivermectin is very widely used and seen as a safe drug. We need to figure out now whether the dosage you can use it at in humans will be effective—that’s the next step,” said the study’s leader Dr. Kylie Wagstaff in a statement.

“We found that even a single dose could essentially remove all viral RNA by 48 hours and that even at 24 hours there was a really significant reduction in it,” she added.”
