The only side effect to Ivermectin I saw was it saved my husband's life. I say "side effect' because the hospital refused him treatment of HCQ or Ivermectin. They were perfectly comfortable with hooking him up to a ventilator and killing him for that payout. My hubby doesn't know it, but he's married to a fighter who doesn't take NO for an answer. He's one lucky man, even if I have to say so myself.
