The AMA, the country’s largest doctors group, is now joining in warning against use of the drug, joining the Food and Drug Administration and the CDC.

“We are alarmed by reports that outpatient prescribing for and dispensing of ivermectin have increased 24-fold since before the pandemic and increased exponentially over the past few months,” the AMA said in a statement, joined by the American Pharmacists Association and American Society of Health-System Pharmacists. “As such, we are calling for an immediate end to the prescribing, dispensing, and use of ivermectin for the prevention and treatment of COVID-19 outside of a clinical trial.”
