Fact check: Are there any reported cases of humans taking horse ivermectin resulting in hospitalization?

1. Summary of the results

The analyses provided suggest that there are indeed reported cases of humans taking horse ivermectin resulting in hospitalization ^{[1] [2] [3] [4] [5] [6]}. Multiple sources confirm hospitalization due to ivermectin toxicity, with patients experiencing symptoms such as altered mental status, neurotoxicity, gastrointestinal symptoms, and musculoskeletal complaints ^{[1] [3] [4]}. The majority of patients in these cases were taking veterinary formulations of ivermectin, which are highly concentrated and not intended for human consumption ^{[2] [1] [6]}. The FDA has received multiple reports of patients requiring medical attention, including hospitalization, after self-medicating with ivermectin intended for animals ^[5]. Additionally, a study found that 19 patients were admitted to the hospital after using ivermectin for the prevention or treatment of COVID-19, with self-medication with veterinary formulations reported in 18 out of 40 patients ^[6].

2. Missing context/alternative viewpoints

While the analyses provide strong evidence for the claim, there is limited discussion on the overall safety and efficacy of ivermectin in human medicine ^[7]. This context is important, as it could help to understand the potential risks and benefits of using ivermectin to treat COVID-19. Furthermore, the sources do not provide a comprehensive analysis of the dosages and concentrations of ivermectin used in the reported cases of hospitalization ^{[3] [4]}. This information would be crucial in determining the likelihood of hospitalization due to ivermectin toxicity. Alternative viewpoints, such as the potential benefits of ivermectin in treating COVID-19, are not thoroughly discussed in the analyses ^[8]. It is essential to consider these perspectives to gain a more nuanced understanding of the issue.

3. Potential misinformation/bias in the original statement

The original statement may be misleading, as it implies that all cases of hospitalization due to ivermectin toxicity are directly related to the use of horse ivermectin ^{[1] [2]}. However, the sources suggest that the primary concern is the use of veterinary formulations, which are highly concentrated and not intended for human consumption ^{[2] [1] [6]}. Pharmaceutical companies and medical professionals may benefit from this framing, as it emphasizes the importance of using prescription-strength ivermectin and highlights the risks associated with self-medication ^{[7] [8]}. On the other hand, individuals who advocate for the use of ivermectin to treat COVID-19 may be negatively impacted by this framing, as it may lead to increased scrutiny and regulation of the drug ^[8]. It is essential to consider these potential biases and misinformation when evaluating the claim ^{[1] [2] [3] [4] [5] [6]}.
