Respectfully, though I understand your effort to warn others, I think it is dangerous at this time to conflate chloroquine derivatives with Chloroquine. Single substitutions in biologically active compounds can cause drastically different effects including substantially different therapeutic ratios. Compare for example the various drugs in the amphetamine family (methamphetamine, amphetamine, MDMA, etc). They are not equally dangerous.

Similarly, the terrible results you report are AFAIK rare with Chloroquine. It is a well tolerated drug and if you're an older or immunocompromised patient playing Russian roulette with a late stage COVID19 infection, the minimal risk is highly preferable to no treatment.
