Recurrent hypoglycemia secondary to drug-dispensing error

Area of Science:

• Pharmacology
• Patient Safety
• Endocrinology

Background:

• Sulfonylureas are commonly prescribed medications for type 2 diabetes.
• Drug-dispensing errors can lead to adverse patient events.
• Hypoglycemia is a significant side effect of sulfonylurea therapy.

Observation:

• Three patients presented with recurrent hypoglycemia.
• Hypoglycemia resolved during hospitalization but recurred upon discharge.
• The cause was traced to inadvertent dispensing of sulfonylurea drugs, not apparent from container labels.

Findings:

• Inadvertent dispensing of sulfonylurea medications caused recurrent hypoglycemia in three patients.
• The dispensing error was identified through detailed medication reconciliation, not standard labeling.
• This suggests drug-dispensing errors leading to hypoglycemia may be underrecognized.

Implications:

• Highlights the critical need for meticulous medication review processes in clinical practice.
• Underscores the potential for medication dispensing errors to cause significant patient harm.
• Suggests a need for improved pharmacy dispensing protocols and patient education regarding sulfonylurea medications.
