> People are literally taking horse formulations of ivermectin People are taking the horse formulation because most pharmacists won't even fill an off-label prescription for the drug, which - even if it has no effect on COVID - is safe and taken by a quarter billion people every year. Let people take it. It's not harmful. Or, make a big huge deal about people taking it and, well, then it becomes a big huge deal.

It's not a placebo pill, it's an active medication that has effects on the body and undergoes metabolism. Ivermectin inhibits cytochrome P450, which the majority of prescription and OTC drugs are metabolized by. Administration of a P450 inhibitor will cause the levels of other medications in a person's blood to rise, and will cause some prodrugs to be ineffective due to reduced metabolism. I can't even walk into a do…

I agree that a doctor should not prescribe a drug that is going to interact dangerously with a patient's other medication. I also agree that a pharmacist should not fill a prescription if they know it will interact dangerously with the patient's other medication.

But I also don't know the dosage schedule doctors who are prescribing Ivermectin are using. They're probably using one from a research paper that they believe justifies its use to treat or prevent COVID. Those dosage schedules are afaict similar to how it's used to treat on-label conditions - take one dose every three months, or whatever.

It's pure speculation that doctors are out there writing prescriptions for dangerous dosages of Ivermectin.

However one thing for sure is that in lieu of a prescription, people are more likely to self-medicate with a dangerous formulation and dosage, ex: horse paste.

I could change every assumption in this comment to the opposite and it would make just as much or little sense. You can’t pretend to be searching for truth if your solution to the problem of people making mistakes is to shut down any possible way to discuss the disagreement. I just find the cognitive dissonance on display here staggering. How do you you know you’re right? Have you ever been wrong? I suppose you knew…

I am not arguing that I know anything to be right or wrong - I am not an epidemiologist or an infectious disease expert, or a doctor. I explicitly said that us non-experts are not able to verify these things on our own. I am saying that those communities of experts have decided that the question of ivermectin’s effectiveness is effectively settled. There are of course experts that disagree - there always are (I work…

> I am saying that those communities of experts have decided that the question of ivermectin’s effectiveness is effectively settled.

Trials[1] don't tend to be run on settled science, so it really does seem that you've taken a position based on political arguments.

> I also never said shut down disagreement. That’s a straw man you created. Anti-vax is not a good-intentioned disagreement

You've said to shut down disagreement based on a standard that requires mind reading. How is that effectively any different from shutting down disagreement? That old Chomsky quote about Stalin being for free speech he agreed with come to mind.

> Allowing pseudoscience to flourish under some strange argument that their positions are as scientifically valid as actual science, is, frankly, nonsense.

This is an actual straw man, by the way, the comment you're replying to made no such faulty conflation.

Since mind reading is back in fashion I will do some clairvoyancy and predict that I will be labelled anti-vaxx for defending the mere possibility of disagreement and dissent. Now there's a problem with a non-zero number of the HN community you should be concerned about.

>Instead, I’m interested in how these “treatments” with no strong evidence are getting weaponized by motivated agents (like the anti-vax crowd) to sow distrust both in scientific organizations (the CDC, and the FDA, Pfizer, Moderna, et al), and in the use of tools with proven effectiveness, like the vaccines themselves. In this polarized environment CDC/FDA/WHO/AMA are political organizations first and authoritative…

Sorry what is the conflict of interest in offering the most accurate information they can? Even discarding whether we drill into the issues with the relatively small body of ivermectin studies, for or against. There isn’t anything approaching a consensus there. On the other hand what does have a consensus is that the vaccines work. Recommending the best possible action is pretty clear and obvious. Using ivermectin as…

>Sorry what is the conflict of interest in offering the most accurate information they can?

* When Fauci was telling people masks aren't needed was he speaking as a scientific authority giving "most accurate information" or was he speaking as a bureaucrat concerned about ppp availability for hospitals?

* When WHO goes against the booster shot narrative is it because of the science or is it because they want vaccines distributed to other parts of the world?

* When these organizations were casting doubt and even CENSORING the Wuhan lab origin theory is it because of the science or because of potential gain of function research and their association?

These "authorities" have chosen to act as political bureaucrats first and they have done it poorly. This is the result.

A friend of mine found a doctor to prescribe it but his pharmacy won't fill it. He is so pissed. He was only planning to take small doses here or there as he's a teacher and around sick kids all the time, as if it were like Zinc to hopefully help reduce the severity of Covid-19 if he does get it, but despite going through the effort and succeeding in finding a doctor willing to prescribe it (and my friend even signed…

> pharmacy shouldn't be allowed to decide not to fill it, as if they know better than your doctor. It sounds like you have a pretty misguided idea of how pharmacies and pharmacists worked before Covid. You’re describing a situation where pharmacists act at the behest of doctors who know best, when in reality pharmacists have always had some level of independent authority over what drugs get dispensed to whom thanks t…

Not really disagreeing that a pharmacist might know more about the drugs than a doctor. I wasn't warned about the potential side effects of Ciprofloxacin once, just told it was an "antibiotic" by the specialist I saw, and the pharmacist did clue me in about some side effects, which I promptly had some of the worst ones after a single pill. I might not have made the connection it was a bad reaction to the pills without their warning, at least not so quickly. I continued to have side effects off and on for years afterwards.

I learned my lesson and now do my own research before just taking any medicine a doctor wants to prescribe now.

But I still don't think pharmacists should be able to just override the decision of a doctor. Make sure the person is fully informed of potential dangers, side effects and correct usage, sure, but not override the doctor. The doctor has had an opportunity to examine and talk to the patient at length, multiple times over multiple visits, and know their history and specific needs, the pharmacist doesn't know any of that background and are most likely just making assumptions.

I mean if it's literal rat poison or a dose guaranteed to kill the person is being prescribed, maybe they can hold off on fulfilling it and alert authorities, but otherwise?

Opioids are a major problem, as there are addicts that cycle doctors to get multiple prescriptions so some doctors might not realize it's being overprescribed, but that's a matter of addiction and abuse and I don't know how a pharmacist is expected to know when it's being abused or not, unless they're getting them all filled at the same pharmacy. Again, they're not spending enough time with these people to know what their situation is. The most interaction I have with my pharmacist is "Picking up a prescription." "Verify your address please?" "My address." "Okay this has these side effects and you should only have it after a meal." "Okay thanks." Yeah that's totally enough for them to make a medical decision on my behalf. /s

If anything, I think them deciding when to withhold medicine could make them MORE liable, not less, because they're inserting themself into the decision process. What if their withholding fulfillment of a prescription results in that person dying? If the doctor said yes and they said no, that seems to open up room for litigation to me.

You’re free to believe that, but understand that this is well in the “wishes and hopes” territory more than a factual understanding of how doctors, patients, and pharmacists actually interact. Personally I believe the idea that we’d spend a huge amount of time and effort as a society training a whole class of specialists and then declare that they must abide by the decisions made by a generalist to be quite odd. Your personal doctor isn’t able to override your oncologist, so why should they be able to override the experts on prescribed medicine?

> If anything, I think them deciding when to withhold medicine could make them MORE liable, not less, because they're inserting themself into the decision process.

I’m sorry, but that’s clearly motivated reasoning and completely unrelated to the actual law. Pharmacists are subject to medical malpractice laws just like every other type of doctor, there’s no magical “I didn’t insert myself into the process therefore I’m not liable” clause.

I'm going to make what is probably a controversial statement, which is that, in my experience, most meta-analyses are trash. A meta-analysis is usually grounded on the assumption that an aggregation of multiple, well-conducted studies can provide significant information that may not be evident by taking each study individually. Essential to this assumption is the premise that those studies included in the meta-analys…

I am also skeptical of meta-analyses. I will re-post some thoughts I have previously shared from John P.A. Ioannidis who is a professor of medicine and thoughtful critic of medical research. He often raises good points about trends in research and research ethics. His view is that meta-analyses are mass produced, redundant, misleading, and conflicted [1]! One criticism of meta-analyses in [1], using anti-depressants…

https://en.wikipedia.org/wiki/John_Ioannidis#COVID-19

> In an editorial on STAT published March 17, 2020, Ioannidis called the global response to the COVID-19 pandemic a "once-in-a-century evidence fiasco" and wrote that lockdowns were likely an overreaction to unreliable data.[14] He estimated that the coronavirus could cause 10,000 U.S. deaths if it infected 1% of the U.S. population, and argued that more data was needed to determine if the virus would spread more.[28][5][14] The virus in fact eventually infected far more people, and would cause more than 600,000 deaths in the U.S.[29][28][5] Marc Lipsitch, Director of the Center for Communicable Disease Dynamics at the Harvard T.H. Chan School of Public Health, objected to Ioannidis's characterization of the global response in a reply that was published on STAT the next day after Ioannidis's.[30]

> Ioannidis widely promoted a study of which he had been co-author, "COVID-19 Antibody Seroprevalence in Santa Clara County, California", released as a preprint on April 17, 2020. It asserted that Santa Clara County's number of infections was between 50 and 85 times higher than the official count, putting the virus's fatality rate as low as 0.1% to 0.2%.[n 1][32][29] Ioannidis concluded from the study that the coronavirus is "not the apocalyptic problem we thought".[33] The message found favor with right-wing media outlets, but the paper drew criticism from a number of epidemiologists who said its testing was inaccurate and its methods were sloppy.

Okay then.

Nothing like spending a career picking apart people's research and then generating absolutely garbage research outside your field of expertise, that is widely criticized by people who are actually the experts in that field...as being inaccurate and sloppy.

COVID hit, dude went all Don Quixote seeing conspiracies everywhere, and then generated a paper that suited his personal biases...

> There is much less safety data on doses that frequent. You can say the same thing about COVID boosters.

And yet there is a wealth of data on both the safety and the efficacy of covid vaccines, and there is also a wealth of data on the effects of getting covid. So why are people going for something without any data?

I specifically said boosters.

However, there is no data on the long-term effects of the COVID vaccines, mRNA or otherwise. That's an indisputable scientific fact. They just haven't existed long enough for that data to be available. Hopefully a decade from now we'll discover that they were safe.

We do have data on the long-term effects of Ivermectin.

Someone who is not concerned about COVID will take neither a vaccine nor Ivermectin. Someone who is concerned about COVID but who is also concerned about the long-term effects of the vaccine may opt to take Ivermectin. It's their choice. It could also end up being the wrong choice.

What I find almost more interesting than the article itself is the comments that show a non-zero portion of the HN community (which I think is generally more intellectually curious and educated than average) are actually strongly arguing that ivermectin has strong effect, and even crazier, that it may be safer or more effective than the mRNA vaccines. Is this from being incapable of following science and drawing rati…

It’s because on this website there is a huge number of people that just drink whatever is the kool-aid du jour that goes around in the right side disinformation circles and social networks. Imagine to oppose a perfectly safe vaccine that has been administered 6 BILLION times all around the world and that has a proven efficacy of at least one order of magnitude against delta variant and to push for a horse dewormer (t…

I see this a lot and it's very strange to see super smart people such as yourself conflate with . We cannot observe long-term effects through number of people.

> “My experience is enough to determine for everyone else” is a really bad look.

Let's put it this way, I haven't seen any evidence based on what I've seen that this isn't the normal interaction with a pharmacist after decades of seeing pharmacists myself, or sitting waiting for my parents to get medicine filled, or watching other users interact with pharmacists while I've been waiting in line, etc., across multiple pharmacies in multiple cities.

If there's a more personal and intimate pharmacist reaction that you see as common (or even uncommon), please share those details for me. I would love to have an example otherwise.

What's the motivation for this sort of thing? It seems the very thing they crave (attention) will invariably bring them undone as attention invites scrutiny.

For one, money. There is an organized group that charges $90 online for hocus-pocus covid medication prescriptions [1]. The more people that can be convinced that this is a worthwhile purchase, the more money they get. https://americasfrontlinedoctors.org/treatments/how-do-i-get...

That and politics. The frontline group was also involved in the Hydroxychloroquine debacle, and they were selected specifically by political actors as a pro-trump solution to the pandemic.

With any of these politically connected things, there’s always a mix of grift, political opportunism, and true believers.
