Why is flumazenil contraindicated in chronic benzodiazepine users who present with acute toxicity?

• A. It has a high risk of seizures by precipitating withdrawal
• B. It is ineffective in reversing benzodiazepine toxicity
• C. It worsens liver toxicity
• D. It causes severe hypotension

Answer: (A)

Flumazenil blocks the benzodiazepine binding site on the GABA-A receptor, so it rapidly reverses benzodiazepine effects. In someone who has become dependent on benzodiazepines, this abrupt antagonism can precipitate withdrawal. Withdrawal from chronic benzodiazepine use often includes seizures, which can be dangerous or life‑threatening. Because triggering seizures is a major and serious risk, flumazenil is contraindicated in chronic benzodiazepine users who present with acute toxicity. The main issue here is not reversing poisoning safely but avoiding a potentially dangerous withdrawal crisis.
