See the 60-second demo →Pediatric medication dosing errors are 3x more common per encounter than adult dosing errors, and the consequences are more severe — children have less physiologic reserve to compensate for an overdose, and weight-based dosing creates more opportunities for arithmetic and decimal-point mistakes. The Institute for Safe Medication Practices (ISMP) has identified pediatric dosing as one of the highest-risk medication safety issues.
The High-Risk Error Patterns
1. Decimal-point errors (10x overdoses)
The classic: a 2.5 mg dose ordered as 25 mg (missing decimal). Or .5 mg ordered as 5 mg (leading zero omitted, decimal misread). ISMP guidelines require leading zeros (0.5 mg) and prohibition of trailing zeros (5 mg, not 5.0 mg) to reduce this risk.
Common scenarios: morphine, fentanyl, methotrexate, chemotherapy agents, anti-arrhythmics. Decimal errors with these drugs are commonly lethal.
2. Weight-based dosing arithmetic errors
Pediatric doses are usually mg/kg. Provider has to: (1) record patient weight correctly, (2) calculate mg/kg × weight, (3) write the order. Errors at any step. Particularly common when weight is in pounds and dose is mg/kg requiring conversion.
3. Adult vial used for pediatric dose
Adult IV epinephrine 1:1,000 (1 mg/mL) used instead of pediatric 1:10,000 (0.1 mg/mL). 10x overdose. Classic error in pediatric code situations.
4. Pump programming errors
Continuous infusion programmed with wrong rate, wrong concentration, or wrong patient weight. ISMP guidelines require dose-error reduction software (DERS) and independent double-check on programmed rates.
5. Look-alike sound-alike (LASA) drug mix-ups
Heparin (anticoagulant) vs Hep-Lock (10x dilution): infant overdoses occurred when adult heparin used instead of pediatric Hep-Lock. ISMP tall-man lettering and storage separation requirements address this.
6. Sedation overdoses
Procedural sedation (ED, dental, radiology) with adult-style dosing in a pediatric patient. Respiratory arrest. The Joint Commission has specific pediatric sedation standards.

The Causation Picture
Pediatric medication overdose causation is often clear: drug X at Y times the appropriate dose causes Z complication. The specific outcome depends on drug:
- Opioid overdose: respiratory depression → hypoxic injury or death
- Insulin overdose: severe hypoglycemia → hypoglycemic brain injury
- Methotrexate daily-instead-of-weekly: severe pancytopenia, mucositis, possible death
- Heparin 10x overdose: hemorrhage
- Sedation overdose: respiratory arrest, anoxic brain injury
Discovery Targets
- Complete medication record with all timestamps
- Pediatric weight documentation (multiple measurements, units used)
- Pump infusion records if applicable
- Pharmacy verification records
- Hospital's pediatric medication safety policy and double-check requirements
- Personnel training records on pediatric dosing
- Pediatric-specific protocols (sedation, chemo, antibiotic dosing)
- Prior pediatric medication errors at the facility
- For Tylenol or NSAID OTC products administered at home: bottle/dose evidence
Damages
Pediatric medication error damages are typically substantial:
- Child death: substantial wrongful death damages, with lifetime parental grief and loss of contribution
- Permanent brain injury: lifetime care, often $5M-$15M
- Permanent organ damage: long-term medical costs, future loss
- Hospital readmission for treatment of complication: medical costs + family disruption
Bottom Line
Pediatric medication errors are documented in the MAR with high resolution. The standards (ISMP, JC NPSG, AAP) are clear. Causation follows established pharmacologic patterns. Damages can be substantial when a child suffers permanent harm or death from a preventable dosing error.
