To evaluate the risks and benefits of flumazenil administration in overdose patients.
To highlight the limited indications for flumazenil use.

Main Methods:

Review of clinical data on flumazenil administration in overdose cases.
Analysis of adverse events and patient outcomes.

Main Results:

Flumazenil administration can precipitate seizures and cause resedation in awakened patients.
