I do believe that ivermectin is useful in treating many conditions...but I do worry about people depending upon it once they become symptomatic...If you get sick seek help and demand monoclonal antibody infusion! once symptoms appear don't sit at home hoping you can treat it yourself... get an infusion and live...of all the treatments it is the best.
I also am concerned that people may get veterinary ivermectin that has other active ingredients in it...make certain it is pure and make certain of your dose!
Using it on the chance it will have prophylactic benefit is one thing...believing it is a magic elixir that can cure anything and bring someone back from the brink of death is another.
I'm taking the usual assortment of supplements including..D3,zinc,C and quercetin...and I have a lot of ivermectin 10mg/cc injectable but have not started taking it as a prophylactic (it tastes bad..lol) and I am really isolated here on the farm..When I have to get off my butt and take care of some necessary business that involves travel I will start the ivermectin.

The prudent hting woudl be to start the ivermectin (or HCQ or whatever regime liek quecitin they wish to do) but also go to doctor’s office if they feel they have covid- there is no reason ivermectin can’t be taken alongside conventional medicines too- that is what Joe rogan did when he got covid, this gives the person the best possible chance- it doesn’t have to be an ‘either or’ situation- Ivermectin now has enough clinical studies and even peer reviewed studies to indicate it works well especially if given early- but still, one shoudl also go to doctors in addition

Very valid concern, and also take the right dose of the correct paste or liquid- the folks that are being poisoned (IF it’s to be believed they are) could very well be taking a whole syringe in one go- not realizing they have to dose it per lb-
IF folks are gettign sick from it- they likely could be taking the one with 2 dewormers in it- and thaqt is a no-no for sure-
