Which statement about benzodiazepine reversal with flumazenil is true?

• A. It cannot reverse midazolam sedation
• B. It has no risk and is universally safe
• C. It has no interactions with benzodiazepines
• D. It can rapidly reverse sedation but may precipitate seizures in benzodiazepine-dependent patients

Answer: (D)

Flumazenil works by blocking the benzodiazepine binding site on the GABA-A receptor, so it displaces benzodiazepines and rapidly reverses the sedative effects of these drugs.

Its reversal is usually fast, but the duration of flumazenil is shorter than many benzodiazepines. That means patients can become re-sedated as the antagonist wears off if a longer-acting benzodiazepine is still present in the system.

In people who are benzodiazepine-dependent or chronically use these drugs, an abrupt reversal can trigger withdrawal, which may include seizures. That risk makes the reversal a careful, monitored intervention rather than something done casually.

So the statement is true because it highlights both the rapid reversal of sedation and the potential for precipitating seizures in dependent individuals, which captures the main clinical considerations when using flumazenil.
