Dispensing error leading to alendronate ingestion.

Area of Science:

• Pharmacology
• Patient Safety
• Medical Error Analysis

Background:

• Medication dispensing errors pose a significant risk to patient safety.
• Similar drug packaging can lead to misidentification and administration errors.
• Asthma medications and bisphosphonates can have similar packaging and dosages.

Observation:

• A 6-year-old boy with asthma was mistakenly dispensed alendronate instead of montelukast.
• The incorrect medication was administered for three months.
• The patient developed symptoms of esophageal irritation, which resolved upon discontinuation of alendronate.

Findings:

• Alendronate and montelukast share similar packaging, increasing the risk of dispensing errors.
• Confirmation bias due to similar packaging contributed to the medication error.
• The incorrect medication caused iatrogenic gastritis.

Implications:

• Distinct drug packaging and standardized bar-coding systems are crucial for preventing medication dispensing errors.
• Healthcare practitioners, manufacturers, and patients must be vigilant to minimize medication errors.
• Reporting medication errors to programs like the United States Pharmacopoeia Medication Errors Reporting Program is vital for system improvement.
