Contributor: Don Stader, MD Educational Pearls: Ivermectin is a Nobel-Prize winning antiparasitic  used to treat filariasis and onchocerciasis Ivermectin is receiving press due to a scientific study examining ivermectin on COVID-19 viral replication in vitro, but the dosages needed for this effect were much higher than is safe for human use Ivermectin has since been studied in humans with no evidence suggesting it is a viable treatment for COVID-19 Ivermectin is a neurotoxin but at normal levels it does not cross the blood-brain barrier Ivermectin toxicity can include altered mental status, seizures, coma, tachycardia, hypotension, nausea, vomiting and diarrhea Treatment of suspected ivermectin overdose is predominately supportive References Caly L., Druce J.D., Catton M.G., Jans D.A., Wagstaff K.M.
