"For hydroxychloroquine to have a benefit, it needs to begin before the
patients begin to suffer some of the severe immune reactions that

Mr Trump raised eyebrows when he said he takes hydroxychloroquine, despite warnings from his own government's health experts. He told reporters that he takes a hydroxychloroquine pill “every day”, combined with zinc.
