Aim: The aim of this study was to compare the characteristics of older and younger patients with suspected paracetamol toxicity. Methods: A retrospective audit of the medical records of older (≥65 years, n = 25) and younger (20–30 years, n = 50) patients with a detectable paracetamol level at a Sydney hospital. Results: Older patients showed a different clinical pattern of suspected paracetamol toxicity and were more likely than younger patients to have multifactorial elevation of liver function tests. Additionally, older age was more likely to be associated with chronic therapeutic paracetamol dosing (71% older, 6% younger, P < 0.001), or with accidental toxic exposure (90% older, 29% younger, P < 0.001), while younger patients were more likely to have a deliberate high‐dose exposure (10% older, 71% younger, P < 0.001). Conclusions: The age‐related differences in paracetamol exposure, paracetamol levels and liver function tests described in this population should be considered when ordering and interpreting paracetamol levels.
