It's been tested for years (decades? it's generic) as an anti-malaria drug. Any drug can be overdosed.
Re:Man dies after self-medicating with chloroquine by Uehreka on Monday March 23, 2020 @07:14PM (#22669888)
It hasn’t been tested against Covid-19. Recommending (or even vaguely hinting) that people just try random drugs that the FDA has approved for other uses is not a strategy with no downside.
Re:Man dies after self-medicating with chloroquine by tomp on Monday March 23, 2020 @07:34PM (#22670080)
There's two reasons to test drugs. (1) To know it's effective. (2) To know it's (reasonably) safe. Chloroquine has passed (2), which is relevant for this article.

Maybe Chloroquine hasn't been tested, but Hydroxychloroquine+azithomycin was tested in a tiny 36 person trial in France, and I believe that's what Trump is basing his "hunch" on. He heard and thought he understood some small snippet of information.

It's been confirmed effective against SARS CoV in vitro [1]. Before you say it, yes, I know treatments in vitro do not always work in vivo.

Reports from China, South Korea and France have suggested efficacy in humans against COVID-19.

Actually they rarely translate.

Chloroquine is a particularly funny example because they have already tried it as an antiviral drug several times without any efficacy.

Re:Man dies after self-medicating with chloroquine by pbreit on Tuesday March 24, 2020 @12:39AM (#22672000)
Can you point to evidence that in vitro efficacy rarely translates to in vivo?

I've seen the one situation of chloroquine showing promise in vitro against SARS CoV but no others. Is there literature on others?

Re:Man dies after self-medicating with chloroquine by ryan_j_naughton on Monday March 23, 2020 @06:55PM (#22669696)
That's an oversimplification.

The amount for an overdose is only around 3X a regular dose (2g vs 600mg) In contrast, most drugs for which you overdose need to be at much higher dosage multiples compared to the prescribed dose.

Re:Man dies after self-medicating with chloroquine by eindiran on Monday March 23, 2020 @07:18PM (#22669927)
There are plenty of drugs with a narrow therapeutic index (NTIs or NTIDs), some of which are available over the counter. Some extremely popular ones: lithium, valproic acid, acetaminophen, almost all anticoagulants (warfarin/heparin), almost all of the -mycin antibiotics (and a lot of other antibiotics), all of the tricylic antidepressants.

See this paper for a very interesting discussion of the topic: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4412688/

Re:Man dies after self-medicating with chloroquine by refurb on Monday March 23, 2020 @07:40PM (#22670130)
Lithium, valproic acid, anticoagulants and -mycin antibiotics (topical excluded) and all anti-depressants are not available OTC in the US.

Acetaminophen has a therapeutic index of close to 8, much better than chloroquine.

Re:Man dies after self-medicating with chloroquine by eindiran on Monday March 23, 2020 @07:56PM (#22670257)
I am not really sure why you think I was listing only OTC drugs. Chloroquine does require a prescription in the US, so comparison with other prescription drugs seems entirely reasonable to me.

Two points on the topic of OTC drugs in the US:

1. Unfortunately you can buy Lithium as a supplement in the US. I have seen bottles of it for sale on Amazon.

2. Having seen enough accidental (not to mention intentional) overdoses from Acetaminophen, I wouldn't be so fast to act like the therapeutic index is wide enough to be treated as "safe". Anything with a narrow therapeutic window needs to be weighed carefully before use. I hope your take away from my comment wasn't that I think chloroquine is "safe": merely that there are a lot of drugs with narrow windows, and there are trade-offs associated with their use. I included that paper because it discusses this very explicitly.

Re:Man dies after self-medicating with chloroquine by refurb on Monday March 23, 2020 @08:09PM (#22670371)
I missed the "some of which are OTC". My mistake.

You are correct that there is a "gray market" for some compounds. The FDA won't come after you for selling lithium carbonate as long as you're not touting it as a medicine. I assume that if it became widespread enough and people got injured, those products would be pulled off the market pretty quickly.

My comments of the TI for acetaminophen was more that it was larger than that for chloroquine. No drug is "safe", but some are safer than others.

Re:Man dies after self-medicating with chloroquine by et2o on Monday March 23, 2020 @07:29PM (#22670026)
People taking warfarin literally have serum levels measured frequently. Typically lithium and valproate too.

TCAs barely used any longer.

Acetaminophen doesn’t belong in this conversation with the other drugs.

Re:Man dies after self-medicating with chloroquine by Johnny555 on Monday March 23, 2020 @07:35PM (#22670086)
Acetaminophen doesn’t belong in this conversation with the other drugs.

I don't see why not? It's a good example where the max therapeutic dose (4000mg/day) is within 2X of the toxic dose range (7500mg-10000mg/day). And even the max therapeutic dose can be toxic to the liver.

And it's exceptionally easy to accidentally overdose if you don't read product labels, since you could be taking multiple products that contain it.

Re:Man dies after self-medicating with chloroquine by et2o on Monday March 23, 2020 @07:41PM (#22670144)
Almost no one should be taking 4g of acetaminophen a day. That’s definitely going to be toxic given enough time.

It doesn’t belong in convo with other drugs because it requires far less monitoring. It’s also not taken chronically like the other drugs. Or shouldn’t be, at least.

Re:Man dies after self-medicating with chloroquine by Johnny555 on Monday March 23, 2020 @07:53PM (#22670234)
Maybe they shouldn't, but isn't that kind of the whole problem with overdose? People take a higher dose than they should?

Acetaminophen overdose is the leading cause for calls to Poison Control Centers (>100,000/year) and accounts for more than 56,000 emergency room visits, 2,600 hospitalizations, and an estimated 458 deaths due to acute liver failure each year.Data from the U.S. Acute Liver Failure Study Group registry of more than 700 patients with acute liver failure across the United States implicates acetaminophen poisoning in nearly 50% of all acute liver failure in this country. Available in many single or combination products, acetaminophen produces more than 1 billion US dollars in annual sales for Tylenol products alone. It is heavily marketed for its safety compared to nonsteroidal analgesics. By enabling self-diagnosis and treatment of minor aches and pains, its benefits are said by the Food and Drug Administration to outweigh its risks. It still must be asked: Is this amount of injury and death really acceptable for an over-the-counter pain reliever?

I have lost track of the point of this conversation.

If you think acetaminophen is qualitatively the same as warfarin or lithium, you need to go to med school.

Re:Man dies after self-medicating with chloroquine by refurb on Monday March 23, 2020 @08:11PM (#22670382)
4g of acetaminophen is what you'd take if you followed the directions of an adult taking 2 regular strength tablets every 4 hours for 24 hours (3.9g to be exact).
Re:Man dies after self-medicating with chloroquine by et2o on Monday March 23, 2020 @08:21PM (#22670439)
I understand that.

That said, any physician who sees a patient taking 4g of acetaminophen a day chronically is going to tell them to reduce their dosage, switch to another drug, or stop.

It’s not safe in the long run.

Acetaminophen is also easy to overdose and has been recommended as a fever reducer for Coronavirus.

UK National Health Service, for one: https://www.nhs.uk/medicines/paracetamol-for-adults/

> NHS coronavirus advice

> There is currently no strong evidence that ibuprofen can make coronavirus (COVID-19) worse.

> But until we have more information, take paracetamol to treat the symptoms of coronavirus, unless your doctor has told you paracetamol is not suitable for you.

> If you are already taking ibuprofen or another non-steroidal anti-inflammatory (NSAID) on the advice of a doctor, do not stop taking it without checking first.

> Updated: 17 March 2020

Over-the-counter use of paracetamol (aka acetaminophen) for fever reduction is entirely standard medical advice, not specific to coronavirus at all.

Strictly speaking it's on the self-isolation if symptomatic or living with someone who does page, and not necessarily aimed directly at confirmed cases, but you also get the same advice at the end of the NHS online advice service if you present with (mild) COVID-19 symptoms:

I'm fairly libertarian so I'm going to say, that's fine. As long as the correct / max dosage is noted on the label/instruction sheet (don't know about US, but in Slovenia, pretty much every drug, even common ones like Aspirin, come with detailed instructions), I don't really see the need to excuse people from being responsible adults (with possible exception for opioids and other addiction-prone drugs).

Perhaps for over the counter medication. This statement is false when we consider drugs requiring a prescription especially those used mainly in acute care or hospital situation. There are all sorts of medications in that class for which a double dose will straight up kill you.

In discussing such situations we often use terms like "patient safety" and "medical malpractice".

The arguments for against this drug seem center around the person recommending it, not its actual efficacy.

Re:Man dies after self-medicating with chloroquine by et2o on Monday March 23, 2020 @07:30PM (#22670043)
Actually there is extremely weak to none evidence for its efficacy in COVID. One terrible French clinical trial.
Re:Man dies after self-medicating with chloroquine by briandear on Monday March 23, 2020 @07:00PM (#22669753)
However nobody should be self-prescribing. The toxic dose is irrelevant because you shouldn’t be taking this drug without a doctor’s supervision. Lithium, a treatment for bipolar disorder is also very toxic and required blood level monitoring but it isn’t being criticized for having the therapeutic dose being so close to the toxic dose. But Trump hasn’t talked about Lithium, so thus nobody cares to complain about it.
