I've always wondered why patients (and doctors) can't try virtually any remedy, at least with any legal drug or substance? Doctors and hospitals are rightly concerned about risks of liability (well, not with the "emergency" meds, which is partially why they enthusiastically promote these!!!). Why can't a patient sign a waiver (give up right to sue) in return for the right (say) to be treated with ivermectin? This concept exists in American law but is (I think) quite rarely used. Sometimes it's even codified into state laws. For example, DMSO does, in fact, have a few FDA-approved uses, but there are many more off-label uses. Florida is one of only a few states that allows doctors to prescribe it off-label, subject to a waiver form that is codified in State law.
