Question

A pre-hospital team is managing a 60-year-old male who has ingested a large quantity of slow-release potassium chloride tablets in a deliberate overdose. His ECG shows peaked T-waves. Why is this overdose particularly dangerous compared to other tablet overdoses?

Accepted Answer

Slow-release preparations continue to release potassium over 12-24 hours - the hyperkalaemia may worsen progressively despite initial treatment; whole bowel irrigation may be needed to remove unabsorbed tablets

Answer

The slow-release formulation makes the tablets non-toxic

Answer

Potassium is rapidly excreted by the kidneys so toxicity cannot occur

Answer

Activated charcoal effectively binds potassium chloride

Answer

Potassium chloride overdose is always benign
