Silent But Deadly: Paracetamol Overdose — A Common Cause of Liver Failure

Paracetamol (also called acetaminophen) is the most commonly used over-the-counter painkiller and fever medicine.

But did you know — Paracetamol overdose is one of the leading causes of Acute Liver Failure (ALF) worldwide, including in India?

It can happen accidentally or in suicide attempts — and can be fatal if not treated on time.

How Does Paracetamol Cause Liver Failure?

Normally, the liver breaks down paracetamol safely.

But in overdose (especially more than 10-15 tablets or >150 mg/kg in a short time) — toxic metabolites accumulate in the liver and cause:

• Liver cell death (necrosis)

• Oxidative stress

• Clotting failure

• Multi-organ dysfunction

Symptoms of Paracetamol-Induced ALF:

Early (within 24 hours):

• Nausea, vomiting

• Stomach pain

• Loss of appetite

Late (after 48-72 hours):

• Jaundice (yellow eyes/skin)

• Confusion / drowsiness

• Bleeding

• Kidney failure

• Brain swelling (encephalopathy)

• Coma

Treatment Protocol for Paracetamol ALF:

"Paracetamol overdose is 100% treatable if detected early. But if liver failure sets in — urgent ICU care and liver transplant may be needed."
— Dr. Chetan Kalal

Life-Saving Treatment Steps:

1. NAC Therapy (N-acetylcysteine)

• Antidote that neutralises paracetamol toxins

• Best results if started within 8 hours of overdose

• Can still work in late-presenting cases

2. Liver ICU Management:

• Intensive monitoring

• Blood sugar control

• Ammonia-lowering drugs

• Kidney support

3. Liver Transplant Evaluation:

If liver failure worsens despite treatment:

• Emergency liver transplant is the definitive life-saving solution.

Prevention is Better Than Cure:

Dr. Chetan Kalal’s Liver Safety Tips:

• Avoid taking more than 1.5 to 2 grams/day of Paracetamol

• Never combine Paracetamol with alcohol or other hepatotoxic drugs

• Store medicines away from children

• Avoid self-medication in fever or viral illness

• Consult a liver specialist in case of overdose
