Accidental staggered paracetamol overdose: An interesting case report

Area of Science:

• Pharmacology
• Pediatrics
• Clinical Toxicology

Background:

• Paracetamol (acetaminophen) is a widely used analgesic and antipyretic, available globally in various liquid formulations.
• Common concentrations for pediatric liquid paracetamol are 120 mg/5 ml and 250 mg/5 ml.
• Discrepancies in available paracetamol concentrations across different countries can lead to unintentional overdoses.

Observation:

• A case of staggered paracetamol overdose was managed over a 24-hour period.
• The overdose was attributed to the use of a higher concentration liquid paracetamol formulation (500 mg/5 ml) available in the UK.
• Misconceptions regarding international dosing similarity contributed to the overdose event.

Findings:

• Accidental therapeutic intent overdose is a significant risk due to varying paracetamol concentrations.
• Effective diagnosis and management of staggered paracetamol overdose require careful patient history and formulation identification.
• Interprofessional and parent-healthcare provider communication is crucial for preventing and managing paracetamol toxicity.

Implications:

• Healthcare providers must be aware of international variations in paracetamol concentrations to prevent dosing errors.
• Patient education regarding correct liquid paracetamol dosing and formulation is essential.
• Enhanced communication strategies are needed to ensure safe management of common medications like paracetamol.
