The FDA provided Emergency Use Authorization to use hydroxycloroquine to treat COVID-19 back in March. I previously have posted a link to the FDA Emergency Use Authorization letter.
Any doctor is free to prescribe hydroxycloroquine to treat COVID-19 in the U.S. It is a medical decision. The doctor can choose not to use hydroxycloroquine if the patient has existing heart conditions or uses Metformin.
Politicians and media pundits should not be hyping drugs as a "cure". The medical community should drive treatment options.
Plenty of trails for hydroxycloroquine are underway. So far the results are not promising that it will be a successful treatment for COVID-19. But keep in mind that most drug trials fail -- only a small percentage are successful.
So your issue is that politicians and media pundits should not be hyping drugs as a cure. I agree with this. They also should not be saying anything "won't work". This gets back to expertise, and neither group has it when it comes to medicine. I assume you apply your critical opinions to both sides of the argument, not just one.
However, they will not stop on either front. That's kind of the way life goes.
