I believe that, I don’t think it works as well as ivermectin. I did three days of ivermectin until I was feeling better then 2 days later almost had to go on oxygen. At the time AFL was changing the protocol along with that other protocol. It was ten days, then five, then until symptoms resolve. I choose wrongly but after a ten day course I was completely better. It only took about 17 hours to get my o2 levels back up from 81 to 98.
