So you're suggesting that taking even a regular dose might send people to the ICU?

The article linked simply says there have been people who misused ivermectin who presented at the hospital. For what reason they went we have no idea because it does not say.

For all we know the two individuals who landed in the ICU were admitted because they were attempting to unsuccessfully self-treat COVID and ended up there, not because of the ivermectin misuse but because of COVID itself.
