The World Health Organization doesn’t recommend ivermectin as a COVID-19 treatment; the drug’s safety and effectiveness remains uncertain in COVID-19 patients
Repurposing existing drugs is a helpful strategy that can accelerate the approval of new treatments against a disease. However, simply because a drug works against one disease isn’t evidence that it will work for another. Therefore, even existing drugs used for one disease still need to demonstrate that they are safe and effective in the context of another disease. While some studies suggest that ivermectin might have a beneficial effect in COVID-19 patients, they don’t provide sufficient evidence to recommend ivermectin as a COVID-19 treatment due to potential biases and small sample sizes.
