Europe restricts chloroquine use to clinical trials or what we'd call "compassionate use." Concerns over whether it has efficacy, and if patients who need the drug and can't get it will not survive without it.

In a Los Angeles Times column, writer Michael Hiltzik outlined flaws. In one of Raoult's studies, for example, six patients dropped out in the first six days; those patients either died, were transferred to the ICU, couldn't tolerate the drug, or dropped for another reason.

"Those six results, however, were not included in the results, meaning that Raoult 'cured' only 100% of those who didn’t get sicker, die, or leave the study," Hiltzik wrote.
