Flumazenil is used to reverse acute benzodiazepine overdose in patients who do not have risk of seizure. True or False?

• A. True
• B. False
• C. Only for long-acting benzodiazepines
• D. Not used due to risk

Answer: (A)

Flumazenil works by blocking the benzodiazepine binding site on the GABA-A receptor, reversing the CNS depressant effects of benzodiazepines. In someone whose risk of seizures is absent, using flumazenil to reverse acute benzodiazepine overdose is appropriate because it can rapidly restore consciousness and airway protection. However, be mindful that the reversal effect may wear off while the benzodiazepine is still in the body, so careful monitoring is needed for potential re-sedation. It can precipitate withdrawal or seizures in benzodiazepine-dependent individuals or in cases of mixed overdoses, so it’s not used when those risks are present. Overall, in a patient without seizure risk, this reversal is the correct approach.
