What is the medical ward admission threshold for paracetamol tablets?

  1. 12 tablets or 6g

  2. 24 tablets or 12g

  3. 30 tablets or 15g

  4. 18 tablets or 9g

The correct answer is: 24 tablets or 12g

In clinical practice, the medical ward admission threshold for paracetamol is based on both the quantity ingested and the potential for liver toxicity, which can occur at doses exceeding 12 grams in adults. The threshold recognizes that ingestion of 24 tablets corresponds to a dose of approximately 12 grams, which is a significant amount and would warrant attention due to the risk of acute liver failure. Monitoring and managing paracetamol overdose is critical, particularly after ingestion of quantities that exceed the safe therapeutic range. This threshold is established to ensure that patients showing potential symptoms or who have ingested this amount can be appropriately assessed and treated in a medical setting. Understanding these treatment protocols is essential for medical professionals when dealing with possible overdoses, ensuring that patients receive timely interventions and that medical resources are allocated to those at risk of serious complications from paracetamol toxicity.
