Thanks for that information. Reading the ivermectin insert it describes it’s actions on insect nervous systems via a mechanism that does not exist in mammals, so it is fairly benign to humans. The package warns not to get it on skin as it could be irritating, but that’s all. The topical stuff is flammable (!) so it has a strong solvent penetrating action… recommended for application along the spine. I am still not clear on ivermectin’s action in a viral infection. I have heard that it doesn’t actually kill the virus, but prevents it from infecting cells… much like selenium does.
Papa is on a Beta-blocker and calcium channel blocker to control his AFIB, and the pacemaker takes care of any low pulse rates that may occur from these. Doesn’t seem to be any possible interaction in case I need to use the Ivermectin on him if he gets infected. But we try to prevent that first.
