Often actions speak with more truth than words.
Doctors and dentists have been called out by pharmacists because they have hoarded hydroxycholriquine. Many articles have been published about this activity, including in the NYT and others. This one is from March but the motive behind the hoarding is pertinent:
Hydroxychloroquine May Not Work Against COVID-19, But Hoarding's Already A Problem : Shots - Health News : NPR
So if doctors and dentists want to secure large personal supplies of it, don’t you think they believe it has beneficial properties? Hoarding large quantities also seems to indicate planned prophylactic use (before becoming very sick/hospitalized) since treatments of advanced disease actually has fewer recommended doses in total. we should be concerned that this may be yet another instance of those who make the rules not following them. “Do as I say, not as I do!” could cause many to needlessly suffer or even die.
