The toxic effects of paracetamol most often occur in the liver and kidneys. Phosphate and lactate turn-over can also be impaired.
Untreated paracetamol poisoning may cause varying degrees of liver injury over the 2 to 4 days following ingestion, including fulminant hepatic failure. Rarely, massive overdose may initially present with coma and severe metabolic acidosis.
Paracetamol is the most common medicine taken in overdose. It can lead to liver failure in a number of days, despite using medication to protect the liver. Liver failure can be fatal. Over 150 people die each year as a result of a paracetamol overdose.
Do not take more than 8 tablets in 24 hours. Taking too much paracetamol can be dangerous and you may need treatment. Too much paracetamol can cause liver damage.
The maximum dose within a 24-hour period must never be exceeded. Paracetamol overdose is one of the leading causes of acute liver failure. Adults can usually take one or two 500mg tablets every 4-6 hours, but shouldn't take more than 4g (eight 500mg tablets) in the space of 24 hours.
Acetaminophen (APAP; a.k.a. paracetamol) is one of the most commonly used drugs in the US [1] and throughout the West, but has a relatively low therapeutic index. The major target organ of APAP toxicity is the liver.
As for Paracetamol of 500mg per tablet, it is generally recommended to take no more than 8 tablets (500mg) within 24 hours, and 24 to 30 tablets taken at one time can lead to overdose or even death.

5. Can I take painkillers on an empty stomach? Ibuprofen, aspirin and other NSAIDs (non-steroidal anti-inflammatory drugs) can irritate the stomach lining, so it is best to take them with food, or a glass of milk. Paracetamol doesn't irritate the stomach lining so it won't matter if you haven't eaten.
Paracetamol works better as a painkiller if taken regularly every 4-6 hours rather than when taken occasionally or as required. The concentration of the drug slowly builds up in the blood stream and in the body tissues when taken regularly therefore giving more pain relief.
But from what has been scientifically established so far, paracetamol is believed to metabolize by mean of obstructing the COX enzymes that are in the human brain as well as that of the spinal cord. This shouldn't take more than 5 hours.

Acute liver failure can happen in as little as 48 hours. It's important to seek medical treatment at the first signs of trouble.
Acetaminophen is harder on the liver than ibuprofen. The liver is the main organ responsible for breaking down acetaminophen. When taken occasionally, and at recommended doses (no more than 4,000 mg per day), it shouldn't cause any liver damage.
It's safe to take ibuprofen with paracetamol or codeine. But do not take ibuprofen with similar painkillers like aspirin or naproxen without talking to a pharmacist or doctor.
