You mean ivermectin (human version) being prescribed and used to treat head lice, scabies, worms - if I had any of those ailments and a doctor prescribed ivermectin (human version) to me, I’d be 100% fine with taking it.
I am fortunate to be on no prescribed medication. I am not a fan of taking a pill for any/every ailment I may have. If I feel a cold coming on, I drink two glasses of orange juice, it usually works for me. I don’t know if it’s the OJ working or is it mind over matter - if one thinks it helps then it can often actually help you.
But would I take ivermectin (human or cow dewormer version) to treat/prevent Covid because of some posters on Yappi - absolutely not.
