Really lovely article. In paramedicine we usually treat 10g of acetaminophen in a 24-hour window as a potentially fatal overdose. That's also why the law in Australia was changed to require acetaminophen to come in blister packs (harder to get each pill out) of no more than 16. At 500 mg, that only gets you up to 8 g if you eat the whole thing, which is still hopefully non-fatal. I always thought a simple over-the-co…

Could somebody package Tylenol with a sufficient amount of NAC to de-risk it? I suspect such a formulation would not require trials?

See superscript 6 on the article. Apparently NAC might has side effects of its own.

Here in Singapore NAC is sold to make muckus more liquid to alleviate coughs. Apparently for some people it also helps with lessening tolerance for their ADHD meds, but I'm not so sure about that.

I'd believe it. I first heard of NAC on the nootropic subreddit in a past lifetime. The benefits vary, but generally it's a safe thing with a low chance of making anything worse, but a possibility to improve things. Many neurodivergent folk have written about how they benefit.

I'd give more info on the exact benefits they found (iirc OCD and rumination loops could be broken more easily), but unfortunately my memory is failing me.

I grew up with the understanding that acetaminophen was the safe choice for fever or aches, and ibuprofen what the more potent compound for inflammation and severe pain. I recall casual anecdotes that "my doctor said 1.5x or 2x ibuprofen dose is ok when warranted" to address major incursions. I've never once thought about taking more than the recommended dosage of acetaminophen, largely because I had no expectation t…

I think most overdoses happen as a result of someone trying to hurt themselves, but I’ve also previously been in sufficient pain (always dental) that I’m counting the minutes down to when I can take more painkillers, so it’s easy to see how you could take double the expected dosage.

It’s also easy to imagine that you may be in a state of confusion and lose track of time and/or the count of doses.

This is some of the most useful information I've received in a while. Like the author, the low overdose threshold of acetaminophen made me avoid it, even though I always take low doses anyway and ibuprofen gives me acid reflux almost every time.

Same here. Great article. I avoid both and stick with naproxen sodium. Any issues with that one? Lasts the longest too.

All the over the counter NSAIDs have a similar safety profile.

I lived with an ICU nurse for years and one of the things he emphasized was the risk of acetaminophen overdose. He's more than once treated the liver failure (and death) from it and by his words, it's one of the worse ways to go.

The positive of it is it got me in the habit of logging whenever I take it, either in a note on my phone or just a sheet of paper I place on my dresser under the bottle. This helps make sure I stay under the 3-4g/d limit.

Last year I was diagnosed with a rare headache disease (NDPH). We thought it completely came out of nowhere, but I had logs in my phone recording headaches and acetaminophen use intermittently from a few weeks prior. This proved useful in the diagnosis.

Moral of the story: log when you take it to avoid overdosing. Combine that with some basic symptom logging (like 1 line, 10 words or less). You never know when that might be useful for your doctors later on.

Earlier quoted context omitted.

I took 2 full packs in a day once while trying to recover from severe pain. Didnt find out until later that it was supposedly a fatal dose.

Mm. Apparently i don't understand pain and the medication it drives people towards.

Totally get it, I too only understood it "theoretically" till I had a (fairly minor!) dental operation.

... Suddenly I'm maintaining a continuous note of when I'm taking which medicine to avoid crossing safe limits (which I anyway was crossing most days).

I was only told to take 2 paracetamols a day (bullshit dose, I'd be waking up from the pain even with more pain meds).

"Diclofenac for rare use" - well, if nothing else is touching the pain, is it an emergency?

Eventually after forever I was able to transition to Ibuprofen + paracetamol. And I already have a health condition which is heavy on my kidneys... pain management can be absolutely crazy.

> What does ingesting 10g of acetaminophen even look like? 20 not-especially-large tablets

Is this not suicidal behavior?

Apparently a common source of problems is taking two different medications without realizing they both contain acetaminophen.

Suppose your arthritis is acting up, so you start taking Tylenol 8hr Arthritis Pain[1]. That's 2 tablets every 8 hours. They're extended-release with 650mg per tablet. A total of 3900 mg in 24 hours.

A few days later you get the flu, so you decide to add what seems like a completely different medication: Theraflu Flu Relief Max Strength[2]. It has a cough suppressant and an antihistamine. But each caplet also contains 500 mg of acetaminophen. It says to take 2 caplets every 6 hours, so you take 8 of them in 24 hours[3]. That's another 4000 mg.

Between the two, you're at 7900 mg.

Then you wake up in the morning and take both medications, but 30 minutes later you've forgotten you took them. You're not thinking straight because you're sick. So you accidentally take a second dose. That additional 2300 mg brings your total to 10200 mg.

[3] You weren't supposed to take 8 of them, though. If you'd read the label very carefully, you'd have seen it also says not to exceed 6 in a 24-hour period.

P.S. like someone mentioned in a comment below happened to them, be careful with NSAIDs over the long term. Until recently I took them daily for better part of 3 years. I was recently diagnosed with chronic kidney disease. Can't definitively say causation, but they definitely contributed. They're fine for short term use but can really f$%# you up with long term, daily use.
