This is a long story, but I will condense it. I was paralyzed from the waist down and in pain for 7 months, doctors didn't know why. I decided to commit suicide. Ex-husband told me he was giving me Oxycontin (I had cancer, only 1 kidney), and I took 40 pills! I had been intentionally poisoned with Tylenol (acetaminophen). He bragged about the switch, it would go undetected, 20,000 mg, and shut down my liver. I was life-flighted to a hospital where my life hung in the balance for 2 months. I lived, and can now walk!

Two days ago I took 11 acetaminophen within 24 hours. I feel tired, dizzy and I am in my periods and I am scared of the amount of medicine I took. I didn't know they were 500 mg because usually I take 3 ibuprofen 200 mg for my headache, and I didn't know I was taking 500 mg medicine after I took all those acetaminophen.

I took Tylenol extra strength 1000 mg at 5:15 a.m. and mistakenly took it again at 7:15 a.m. I am concerned about acetaminophen poisoning.

I am 66 years young and in fair health. I was a critical care nurse for 35 years and very satisfied with my work. I began having pain in my back in 2004, then I was host to a serious lung infection. I had to stop working in 2006. I was on patches for my back pain and taking acetaminophen for arthritic pain. The patches were not doing as well as they were eight years ago. I was taking up to six extra strength per day. I thought I was safe. Package warnings should include information about long-term use of acetaminophen. My first symptom was debilitating nausea and weakness. Saliva was pouring from my mouth and nose, and abdominal pain was constant. I perspired profusely. The acute phase lasted about 45 minutes. I hallucinated people in my home and about the house for 12-14 hours. I was aware that I was hallucinating, but it still was disconcerting.

A lot of diarrhea and a weight loss of 6 pounds in 2 or 3 days.

I had a Tylenol overdose a few years ago. I was 18 years old and took 17,000 mg of extra strength Tylenol. I didn't have any symptoms until about 5 hours after I took the pills. I felt very nauseas and vomited a lot. I could barely walk. My dad found me and took me to the emergency room where they gave me an antidote through my IV. I spent a couple days in the critical care unit then was sent to a psychiatric hospital. In the emergency room they told me they were going to put me on the transplant list because there was no way my liver would function after taking so much. But I was released with no long term effects to my liver or the rest of my body. I was lucky. I realize that now. The pain of a Tylenol overdose is horrible. That is no way to die. I realize that now and now I live a happy life. I finish school this year to be a paramedic. I want to save lives because now I know just how precious they are.

I just got over an accidental overdose of acetaminophen. I take Tylenol tablets to control chronic pain, then got a cold and started taking medication for that which also had Acetaminophen in it. I did back off of my regular pain reliever, but what I didn't realize, that this article has helped greatly with, is that the drug levels build over time, and an overdose can lie dormant for a fair while.

I had no symptoms at all, although they told me in the hospital I had a toxic amount in my system.

Thank you for your help. Four extra strength Tylenol every 4 hours for 16 hours will be enough.

Nyquil/night time has acetaminophen in it, and is really the only thing that relieves my pain, all my pain. I have 3 pain relievers my doctors prescribe me and for some reason they don't give me stronger ones. I use night time when I can't take the pain any longer and relief it is. I got on this site to see if my doctors could change my meds to prescribe something that had acetaminophen. My research on acetaminophen as I have peripheral arteries disease, and fibro.
