My mom has knee pain and the doctor has her taking acetaminophen. Since my aunt died 2 years ago from acetaminophen induced liver damage, I told her she should take NAC/N-acetyl cysteine. So now she comes to me and says the nurse was questioning her taking NAC, has never heard of it. I remember buying NAC 20 years ago for my liver before I ever started lifting because I was drinking all the time at college. Am I wrong that this should be common knowledge to someone in healthcare?

Acetaminophen is about as common as it gets for OTC pain relief in Aus/UK/NZ and nothing is said about its side effects compared to NSAID (iBuprofen especially) because they are so damn low if taken at low doses so NAC just doesn't get talked about.

Very few stack NAC and nobody is out there claiming it has enough benefits for the general population for performance enhancement compared to joint health stuff, vitamin B/C/D, BCAA's, detox, green cleanse, antioxidants etc

The nurse might know it by another name for treating the borderline personality disorder girls who come through ED or psych wards for paracetamol overdose but for a nurse at the family doctor, no, no reason to know it.
