Medications which can kill a toddler with one tablet or teaspoonful

Area of Science:

• Medical Toxicology
• Pediatric Pharmacology

Background:

• Accidental ingestion of medications poses a significant risk to young children.
• Identifying specific drugs that are acutely toxic to toddlers is crucial for prevention.

Purpose of the Study:

• To identify medicinal preparations that can be fatal to a toddler (10 kg) upon ingestion of one standard dose unit.
• To compare calculated fatal doses with real-world poisoning data.

Main Methods:

• Reviewed four major medical toxicology texts for fatal poisoning cases in children and fatal doses in adults.
• Identified the largest commercially available dose units using the Physicians Desk Reference.
• Calculated the number of dose units a toddler would need to ingest to reach a fatal dose.
• Analyzed annual reports from the American Association of Poison Control Centers National Collection System (1983-1989).

Main Results:

• Very few drugs are fatal to a 10 kg toddler with a single commercially available dose unit.
• Lethal single-dose drugs include camphor, chloroquine, tricyclics, phenothiazines, quinine, methyl salicylate, and theophylline.
• These specific drugs accounted for 42% of fatal acute ingestions in children under 2 years old in the US (1983-1989).

Conclusions:

• A small number of commonly available medications present a high risk of fatality for toddlers with single-dose ingestion.
• Unique labeling of these high-risk drugs could help reduce severe and fatal poisonings in young children.
