Paracetamol poisoning rises
The annual number of paracetamol poisoning cases is ballooning.
The annual number of cases of paracetamol poisoning in Australia has increased by 44.3 per cent since 2007-08, and the number of cases of toxic liver disease due to those overdoses ballooned by 108 per cent over the same period, according to new research.
The experts say public health measures that restrict the availability of paracetamol, such as reducing non-prescription pack sizes, are needed to stem the increasing number of paracetamol overdoses.
The study used data from a range of morbidity and poison databases to find that;
- there were 95,668 admissions with paracetamol poisoning diagnoses (2007–08 to 2016–17)
- the annual number of cases increased by 44.3 per cent during the study period
- toxic liver disease was documented for 1816 of these patients; the annual number increased by 108 per cent during the study period
- most paracetamol overdoses involved women (about 70 per cent)
- the NSWPIC database included 22,997 reports of intentional overdose with paracetamol (2004–2017)
- the annual number of intentional overdoses increased by 77 per cent during the study period
- the median number of tablets taken increased from 15 in 2004 to 20 in 2017
- modified release paracetamol ingestion report numbers increased 38 per cent per year between 2004 and 2017
- 126 in-hospital deaths were recorded in the NHMD, and 205 deaths (in-hospital and out of hospital) in the NCIS, with no temporal trends
- the median age of patients in the NSWPIC database was 18 years. The median age in cases of fatal overdoses recorded in the NCIS was higher (53 years), perhaps reflecting greater suicidal intent in overdoses by older people or the presence of comorbid conditions that increase the risk of liver injury
