Paracetamol overdose is one of the leading causes of liver failure. Scientists have known for decades that paracetamol in large amounts is toxic the liver, but until now its mechanism of poisoning has eluded them.
In general, paracetamol poisoning is associated with hepatotoxicity and very rarely with renal impairment in the absence of significant hepatic impairment. Paracetamol poisoning associated with renal impairment is rare, and it is mostly associated with hepatotoxicity.
What a paracetamol overdose does to your body. Paracetamol itself is not toxic, but in large amounts it overwhelms the body's ability to process it safely. This can lead to build up of a toxic metabolite (or break-down product), which binds to liver cells, causing these cells to die.
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.
Taking 1 or 2 extra tablets is unlikely to harm you. 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 daily dose of 4 g in any given 24 hour period should not be exceeded as well. Paracetamol is generally a safe, non-prescription pain reliever, but misuse and overdose do occur. This is because so many medications contain paracetamol that it's easy to take too much of the drug without realizing it.
The recommended paracetamol dosing for adults and children 12 years and over is 500 to 1000mg every four to six hours as necessary, with a maximum of 4000mg in any 24 hour period.
While acute liver injury can occur when used at or below the recommended daily maximum dose (4000 mg)[4], paracetamol toxicity is often the result of ingestion of paracetamol over this maximum dose.
Acetaminophen (paracetamol), when taken in reduced doses (maximum 2–3 grams per day), is generally considered to be the safest pain relief option for your liver.
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 is generally considered safer than other pain relievers. It doesn't cause side effects such as stomach pain and bleeding.
Acetaminophen remains the drug of choice for occasional use in patients with kidney disease because of bleeding complications that may occur when these patients use aspirin.
Reversing liver damage Liver Basics
For example, an overdose of acetaminophen (Tylenol) can destroy half of a person's liver cells in less than a week. Barring complications, the liver can repair itself completely and, within a month, the patient will show no signs of damage.
These symptoms include feeling tired, abdominal pain, or nausea. This is typically followed by absence of symptoms for a couple of days, after which yellowish skin, blood clotting problems, and confusion occurs as a result of liver failure.
If the glutathione runs out, then the toxic substances build up and damage liver cells. An adult body can produce enough glutathione to safely clear 4 grams of paracetamol every 24 hours which is why it is the recommended dose. Taking more than this amount risks permanent and even fatal liver damage.
Adults can usually take 1 or 2 tablets (500mg) every 4-6 hours, but shouldn't take more than 4g (8 x 500mg tablets) in the space of 24 hours. Children under 16 need to take a lower dose, depending on their age or weight – check the packet or leaflet, or ask a pharmacist or doctor for advice.
