Adverse Drug Reaction: Midazolam-Induced Extrapyramidal Symptoms: A Case Report

Area of Science:

• Anesthesiology and Pharmacology
• Neurology

Background:

• Midazolam is a widely used sedative for procedural sedation due to its safety and predictability.
• Rare adverse drug reactions associated with midazolam have been documented.

Observation:

• A patient developed acute onset dyskinetic extrapyramidal symptoms after receiving midazolam prior to a peripheral nerve block.
• These extrapyramidal symptoms were unexpected and presented as involuntary movements.

Findings:

• The administration of midazolam precipitated a rare neurological adverse event.
• Flumazenil, a specific antagonist for benzodiazepines like midazolam, successfully reversed the observed dyskinetic symptoms.

Implications:

• This case underscores the importance of recognizing rare adverse effects of commonly used medications like midazolam.
• Clinicians should be prepared to manage unusual reactions, including having flumazenil readily available for potential midazolam reversal.
• Awareness of these potential midazolam side effects is crucial for patient safety across various medical disciplines.
