Definition
Taking more than the recommended amount of paracetamol. (2x500mg, 4 times a day with 6 hour gaps between each dose).
Epidemiology
I think the big red thing covers it. It's more common in girls because it's generally a form of parasuicide but blokes do it too.
Pathophysiology
Basically, paracetamol is metabolised by conjugation with two chemicals called sulfate and glucuronide; some is oxidised by the cytochrome P450 enzyme system. Producing a substance called NAPQI which is metabolised by glutathione.
In high levels, the glutathione runs out, leaving NAPQI floating around the liver. 'NAPQI kills liver cells i.e. it's hepatotoxic. This is what does the damage.
