Paracetamol-associated knowledge, attitudes and practices of the New Zealand public: an online survey

Although paracetamol is the most widely used prescription and over-the-counter drug globally, it also has a higher toxicity than other common non-opioid analgesics and is a leading preventable cause of acute liver failure and liver transplants. International evidence suggests that the public may have inadequate knowledge about paracetamol; however, in Aotearoa New Zealand (NZ), paracetamol is relatively cheap and readily available in large quantities at pharmacy and non-pharmacy outlets.

To identify paracetamol-associated knowledge, attitudes and beliefs of the NZ public.

Using Horizon Research Limited, a NZ-based research panel, we explored paracetamol-associated knowledge, attitudes and practices using an online survey.

A total of 1723 respondents completed the survey. High rates of unintentional misuse of paracetamol were identified, in addition to significant knowledge gaps, particularly those related to participants' ability to identify paracetamol-containing formulations. Participants were also supportive of introducing policies restricting the supply and sale of paracetamol, such as where paracetamol can be purchased.

There appears to be a need to increase the NZ public's knowledge of the safe use of paracetamol. Given the current lack of policies restricting access to paracetamol, the substantial proportion of the NZ adult population exceeding paracetamol dosing guidelines, and the public's apparent support for introducing policies, our findings may have important implications. However, research is required to understand the potential impact of tightening current regulatory policies, including restricting where you can purchase paracetamol or reducing the amount of paracetamol you can purchase at once, before they are introduced.
