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.<p>I've never once thought about taking more than the recommended dosage of acetaminophen, largely because I had no expectation that it would provide additional benefit..<p>In reality, I try to consume 1/2 doses of anything or nothing at all, unless it's a serious medical treatment being administered by a professional.

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.

My father, who is otherwise in very good health for a ~60 year old, has severely reduced kidney function from taking an ibuprofen+antihistamine most days of his early life to deal with allergies.<p>I'll second the claim that no doctor at any point in his life had told him the risks of doing that, and many encouraged the use of ibuprofen over any other alternative (including the alternative of not using OTC painkillers every single day).

Well, I mean, <i>drats</i>. I too always assumed Ibuprofen was safer than Acetaminophen; not the least because of massively oversimplificatic "reduced inflammation - GOOD!" 'Logic'. I'm 47 now and have probably preferred ibuprofen for last 27 or so.

Both of these pills are really dangerous for dogs.<p>Ibuprofen damages the kidneys -- and that damage is often permanent. The little filtering devices inside the kidneys don't grow back once they're destroyed. A dog who survives the poisoning can end up with lifelong kidney disease, which means special diets, more frequent vet visits, and a shorter life than she should have had.<p>(I watched this happen to my own dog after a house sitter stepped on her paw and gave her ibuprofen to "help." My dog lived, but she needed a special diet for the rest of her life.)<p>Acetaminophen wrecks the liver, and it also can damage red blood cells so they can't carry oxygen properly. A poisoned dog may get lethargic, vomit, start to breathe heavily... This is especially dangerous for older dogs, or any dog whose red blood cells are already compromised, by conditions like IMHA.
