Oregon Poison Center Reports 21 Horse Paste Cases

Consumer Health reports:

Twenty-one cases of poisoning for ivermectin exposure relating to COVID-19 were reported to the Oregon Poison Center in August 2021, according to a letter to the editor published online Oct. 20 in the New England Journal of Medicine.

Courtney Temple, M.D., from the Oregon Health and Science University in Portland, and colleagues describe the calls received by the Oregon Poison Center regarding ivermectin exposure in August 2021.

The researchers note that there were 21 calls in August 2021; 11 of the callers were reported to have used ivermectin to prevent COVID-19 and 10 used it to treat symptoms of COVID-19. Three people had received prescriptions from physicians or veterinarians; 17 had purchased veterinary formulations.

The New England Journal Of Medicine reports:

Six of the 21 persons were hospitalized for toxic effects from ivermectin use; all 6 reported preventive use, including the 3 who had obtained the drug by prescription. Four received care in an intensive care unit, and none died. Symptoms were gastrointestinal distress in 4 persons, confusion in 3, ataxia and weakness in 2, hypotension in 2, and seizures in 1. Of the persons who were not admitted to a hospital, most had gastrointestinal distress, dizziness, confusion, vision symptoms, or rash.

These cases illustrate the potential toxic effects of ivermectin, including severe episodes of confusion, ataxia, seizures, and hypotension, and the increasing frequency of inappropriate use. There is insufficient evidence to support the use of ivermectin to treat or prevent Covid-19, and improper use, as well as the possible occurrence of medication interactions, may result in serious side effects requiring hospitalization.
