Note that the doses required here are MUCH higher (one European hospital tried 1000mg doses) which is toxic. It can result in blindness, heart failure and other issues.
Retinal damage is not an issue unless you take it for years. Heart failure is not an issue in a hospital because it's not sudden, so all treatment protocols specify that patients are monitored for QT prolongation. Moreover if you don't get it right away, you're unlikely to get it at all. "Other issues" in this case are mostly nausea and diarrhea. I don't know about you, but I'd rather shit myself than die.
