Over a year ago I ran into some kind of warning about the kind of anti-coagulant to use for people with problems related to Covid. I don’t remember the details or the reference, but I think it was the use of heparin that was the concern. Some other kind was recommended.
I vaguely remember that too; I think it was when they were comparing COVID coagulation to the more often seen (at least at first) DVT following, say, hip or knee surgery, or extended hospital bed stays, or both.
