Superwarfarin rodenticides cause long-lasting anticoagulant effects. A case shows recovery from bromadiolone poisoning took a month, highlighting the need for careful vitamin K management and monitoring.

Area of Science:

  • Toxicology
  • Pharmacology
  • Internal Medicine

Background:

  • Superwarfarin rodenticides are potent, long-acting anticoagulants.
  • Easy accessibility leads to accidental or intentional human poisonings.
  • Warfarin is a less potent, shorter-acting anticoagulant.

Observation:

  • A case of voluntary poisoning with bromadiolone (RATIBRONÂ) is presented.
  • The patient ingested approximately 27.5 mg over two weeks.
  • Minor bleeding episodes were observed.

Findings:

  • Anticoagulant effects and clotting test abnormalities persisted for about one month.
  • Correction of hemostasis defects requires extended management.
  • Gradual vitamin K dosage reduction and International Normalized Ratio (INR) monitoring guided safe evaluation of therapeutic response.

Implications:

  • This case underscores the prolonged anticoagulant activity of superwarfarins.
  • Lack of specific treatment guidelines necessitates individualized patient management.
  • Vitamin K therapy combined with regular INR monitoring is crucial for managing superwarfarin poisoning.
