BEND, Ore. (AP) — Around two dozen people have contacted the poison center in Oregon after self-medicating against COVID-19 with a drug used to treat parasites, with five becoming hospitalized and two of them winding up in intensive care units. The drug they used was ivermectin, which has no proven use against the coronavirus and is instead approved to treat some parasites in people and some animals. Between Aug. 1 and Sept. 14, the Oregon Poison Center at OHSU managed a total of 25 cases. The medical director of the Oregon Poison Center said people shouldn’t use unproven and potentially dangerous drugs to fight COVID-19.
