It was a panacea, but not the good kind. Hydroxychloroquine, praised in a French study and at the White House podium, has lost its shine as a potential COVID-19 treatment.

Observers say the biggest sign that the drug and its cousin chloroquine have fallen from favor is that Fox News' positive coverage of them has gone silent.
