Fact-Check Article: Hydroxychloroquine Overdose Claims

What We Know

The claim in question suggests that some studies of hydroxychloroquine (HCQ) for COVID-19 resulted in patients being poisoned with doses exceeding 9 grams of the drug. Hydroxychloroquine is primarily used to treat rheumatologic diseases and has been investigated for its potential efficacy against COVID-19.

  1. Toxicity Levels: According to a review on chloroquine and hydroxychloroquine toxicity, acute toxicity can occur with doses as low as 2-3 grams, and the most commonly reported lethal dose in adults is between 3-4 grams. Severe toxicity has been documented in cases where patients ingested significantly higher amounts, such as 24 grams, leading to severe complications including cardiac arrhythmias and hypotension (Richardson et al.).

  2. Case Reports: A notable case reported in the literature involved a 49-year-old woman who ingested 24 grams of hydroxychloroquine in a suicide attempt. This case highlighted the severe cardiotoxic effects and the complex management required for such overdoses (Richardson et al.).

  3. Clinical Studies: Various studies have explored the use of hydroxychloroquine in COVID-19 patients, with findings indicating that it did not significantly reduce mortality or the need for intubation (RECOVERY Collaborative Group). Despite this, the drug was widely prescribed during the pandemic, leading to increased reports of toxicity.

Analysis

The claim that studies of hydroxychloroquine resulted in patients being poisoned with doses over 9 grams is partially true. While it is accurate that severe toxicity can occur at doses exceeding 9 grams, the context of "studies" leading to poisoning requires clarification.

  1. Overdose Incidents: The literature does document instances of overdose, particularly in non-clinical settings where individuals self-administered high doses, often with suicidal intent. For example, the case of the woman who ingested 24 grams illustrates the potential for severe toxicity, but this was not a result of clinical trials or studies, rather an isolated incident (Richardson et al.).

  2. Clinical Trials and Safety: Most clinical studies involving hydroxychloroquine for COVID-19 did not administer doses anywhere near the toxic levels cited. The typical doses used in trials were significantly lower, and the adverse effects reported were generally related to the drug's safety profile rather than acute poisoning (Della Porta et al.).

  3. Source Reliability: The sources referenced in this analysis are credible, with peer-reviewed articles and clinical case reports providing a detailed account of hydroxychloroquine's toxicity. However, the interpretation of these findings should be approached with caution, as the context of overdose cases differs from the controlled environments of clinical trials.

Conclusion

The claim that studies of hydroxychloroquine for COVID-19 poisoned patients with doses exceeding 9 grams is partially true. While there are documented cases of severe toxicity from high doses, these incidents primarily stem from intentional overdoses rather than from clinical studies. Most clinical trials adhered to safety protocols and did not involve such high doses, indicating that the assertion lacks complete context.

Fact Check: We have 50 years of data that tells us what corporations do with tax cuts. This has been one of the most studied things by universities around the world for the last 50 years. And in the last 50 years across 18 of the wealthiest nations in the world not one has corporate tax cuts equated to higher job growth. 00:35 Not once. Or we can just look at the Trump tax cuts passed in twenty 17. Donald Trump created 40, 000 less jobs a month than Barack Obama did. And oh by the way that's leaving out COVID. That's leaving out all the job losses from the pandemic. There is one thing that happens when you give corporations big tax breaks. This right here. 50 years of data. You see that red line on top? That's the rich getting richer. You see those two lines on the bottom? That's the bottom 905percent? No In 01:06 twenty 18 corporations spent over a trillion dollars on stock buybacks and created less jobs than they did in twenty fourteen, 15, 16, and seventeen. You see the rich can afford to pump all of this misinformation into your brain. And that's why you believe it. There's not a single case in history of tax cuts for the rich helping an economy in any way shape or form.

Fact Check: Obama became president illegally because he was born in Kenya. The Bush family is involved in the New World Order (NWO). Hillary Clinton was passed over by the Vatican for the presidency because people care more about race than character. The Vatican is described as "Satan's earthly HQ" and supposedly orchestrates various political events. Trump was anti-Illuminati, fought a stolen election, and was targeted by a coup and various conspiracies. The COVID-19 mRNA vaccine is framed as part of a satanic/globalist plan (NWO). Jesus gave Trump two terms because of what the Vatican did on 9/11.

Fact Check: Transcript 00:00 911 was a false flag. For the first 10 years, I did not think anything other than the official narrative then after being shown a video, a close up video of building number seven coming down and that got me going because it's obvious to me that building seven was was a controlled demolition because the building collapses from the bottom down. The trade centers were unique in that they were designed to withstand the 00:33 impact of a a a jet. From what I understand the the outer skeleton of the building. The outer columns was like a a fish net and you had these inner core columns which was substantial thick steel beams to withstand four or five times what the loads were. Got it. The engineers always over design a building. No steel frame building has ever collapsed before or since 9/ eleven. So that should say something right there. And it said that building seven it was 01:05 aggressive collapse that it was caused by fire but progressive collapse unlike the twin towers, the twin towers collapse from the top down. That's a progressive collapse. Sure. Floor by floor by floor. But if you look at the videos of building seven collapsing, it collapses uniformly, it's collapsing from the bottom, the building stays intact all the way to the bottom of the ground and you could see the sides caving in on it. For a building to collapse uniformly which the video show all the load bearing it would have to have failed 01:36 simultaneously. Now, fire doesn't act like that. I came across an analogy of the twin towers and if you could visualize cast iron stoves stacked. One on top of each other. The stoves up at the top. Yes, there's fire and they've been damaged but the stoves on the bottom, they haven't been damaged. Okay. So, the structure underneath all of that is intact. So, it's impossible for a building to collapse near free fall speed and increase. Without a 02:07 controlled demolition. You're running into the path of most resistance. I something else is going on. I don't believe that it was just the planes or the fires I think that and they examine the dust and they found what they call thermitic material which is like a explosive incendiary which was in the dust samples and that's documented. There were reports of the buildings were undergoing a extensive elevator renovation in the two or three years prior to all kinds of 02:40 workers they had access to the the core the cores of the building and on the day of the attack the the elevator company would not assist in the operations of the elevators and the elevator company was the elevator company it subsequently went out of business and a couple of years after that
