Clinical characteristics of hospitalized patients with paracetamol poisoning before and after restrictions of over-the-counter sale of paracetamol.

The present study demonstrated a lower number of paracetamol poisonings, a decreased proportion of poisonings involving ingestion of more than 20 g of paracetamol, and a lower occurrence of hepatotoxicity after the regulation. However, circumstances other than pack size restrictions, such as increased public awareness of the danger of paracetamol poisonings, may affect these associations. Furthermore, the study showed that females and males constitute two distinct groups in terms of age and intentional poisoning.
