Dipyrone overdose typically causes mild gastrointestinal issues, not severe agranulocytosis. Early decontamination is key for managing dipyrone toxicity.

Area of Science:

  • Pharmacology
  • Toxicology
  • Clinical Medicine

Background:

  • Dipyrone, a pyrazolone derivative, is used for pain and fever relief.
  • Agranulocytosis is a serious adverse effect, leading to bans in some countries.
  • Dipyrone remains widely used globally, with limited data on overdose effects.

Purpose of the Study:

  • To characterize the demographic and clinical features of dipyrone overdose.
  • To identify risk factors and outcomes associated with dipyrone overdose.

Main Methods:

  • Retrospective analysis of prospectively collected poison center data.
  • Included 243 cases of acute dipyrone exposure over three years.
  • Utilized descriptive statistics, Mann-Whitney, and Chi-square tests.

Main Results:

  • Median age was 17 years, with a median overdose of 5g.
  • 16% of patients experienced toxic events, primarily mild gastrointestinal symptoms.
  • Symptomatic and suicidal ingestions involved higher doses; no agranulocytosis was reported.

Conclusions:

  • Dipyrone overdose is linked to mild, mainly gastrointestinal toxicity, often at doses around 7.5g.
  • Early gastrointestinal decontamination may mitigate toxicity.
  • Recommended treatment includes decontamination and supportive care.
