He said he has seen ivermectin work at every stage of COVID — preventing it, eliminating early infection, quelling the destructive cytokine storm in late infection, and helping about a dozen patients so far who suffered months after COVID.
“When you have people that can’t breathe for five, six, eight, nine months and they tried multiple drugs and supplements with no success, and you give them ivermectin,” Dr. Santin said of long-haul patients, “and you see that they start immediately feeling better, this is not placebo. This is real.”

The majority of patients improved within one to three days, he said, particularly those with breathing problems, debilitating fatigue and chest pain.
“Use your brain. If your patient is dying, change something, try to do something more.”
