I already know that with the nature of my personal health conditions Chloroquine would not be an option for me if I come down with COVID. Brazil has just announced that it is halting a small test of its effectiveness for safety reasons. An interesting note,since Chloroquine is actually a "recommended treatment for COVID patients" under Brazil's national guidelines, the study was unable to use a placebo in the study which only involved 81 test patients...
"A small study in Brazil was halted early for safety reasons after coronavirus patients taking a higher dose of chloroquine developed irregular heart rates that increased their risk of a potentially fatal heart arrhythmia.
Chloroquine is closely related to the more widely used drug hydroxychloroquine. President Donald Trump has enthusiastically promoted them as a potential treatment for the novel coronavirus despite little evidence that they work, and despite concerns from some of his top health officials. Last month, the Food and Drug Administration granted emergency approval to allow hospitals to use chloroquine and hydroxychloroquine from the national stockpile if clinical trials were not feasible. Companies that manufacture both drugs are ramping up production."
