Expired acetaminophen toxic to liver?

Hey Pharmily, I’m reading a book about vestibular migraine and in the section about rescue treatments there’s a statement that reads:

> Expired acetaminophen breaks down into compounds that are toxic to the liver.

I am only aware of tetracyclines being toxic when expired, and I cannot find any information about this being the case for acetaminophen (nor do I have any personal experience with liver toxicity in my two-year expired apap that I use like a bad pharmacist).

Can anyone corroborate this statement?
