It has been considered a last resort in treating a select handful of few diseases, and then only with constant patient monitoring.
It was especially silly to promote it then, at a time when fear was so high and reason so low. In my opinion the president and his Fox News puppets shouldn't be promoting anything. They're not an authority on medical consensus. It was revealed Trump had financial connections to HCQ as well, which just makes the whole situation 300% more frightening and inappropriate.
There are ways to accelerate controlled studies, but the way to do that is not by having the spokesperson of the country encourage every hayseed yobbo run down to the fish supply store and start snorting non-medical grade powder. Do you not see how a line has been crossed in going from accelerating medical research, to this?
Are you kidding me? Hydroxychloroquine has been given prophylactically to people traveling into areas with Malaria that might get sick for decades. People are taking this drug chronically for lupus and rheumatoid arthritis. This drug isn't a last resort for a number of diseases. It isn't particularly dangerous when taken as prescribed by a doctor. Hell, I took this drug a few decades ago before traveling to a region in South America where malaria was endemic. The doctor wrote me a script, handed it to me, and said "Take this as written on the bottle a week before you leave", so I took it without having any disease.
It can cause QT prolongation like any number of other drugs routinely prescribed. Like for instance most of the tricyclic antidepressants and probably at least a dozen other drugs. If you are susceptible to QT prolongation you might have an issue with hydroxychloroquine just like you might with nortriptyline.
The risk is low, the cost is low, and there is to this day some evidence that it might be useful.
You really are letting your hatred of a particular politician blind you to what was very arguably a reasonable course of action. Trump is ineloquent. He speaks and tweets frequently without thinking. But prodding the FDA to get off their ass and investigate a low cost readily available drug that had every bit as much evidence behind it when this all started as remdesivir was the right thing to do. I wish he was more well spoken about it, but the FDA is a highly sclerotic bureaucracy and honestly that sort of public prodding is possibly required.
Contrast this with remdesiver which got virtually all of the initial press. It like HCQ had a single in vitro study showing that it might block SARS. But, it has never been approved, has only been produced in small batches in a research laboratory (never in a production facility), and is going to cost a king's ransom if it works. And if it does work, you're probably looking at 6 - 12 months to ramp it to volume production so you could use in widely.
HCQ has many features to recommend it over remdsiver - If either of them end up working that is.
But stop it with this notion that a drug that has been prescribed for decades prophylactically is some seriously dangerous compound. Do you image that remdesivir is going to be free from side effects? It hasn't even be trialed enough to know what it's warts are.
