What is the antidote used for benzodiazepines?

• A. Naloxone
• B. Prothrombin complex concentrate
• C. Vitamin K
• D. Flumazenil (Romazicon)

Answer: (D)

Flumazenil is the antidote for benzodiazepines, acting as a competitive antagonist at the benzodiazepine binding site on the GABA-A receptor. In overdose or excessive sedation, it can rapidly reverse CNS depression and restore consciousness and breathing, which is why it’s used in carefully monitored settings. Because it has a shorter duration of action than many benzodiazepines, symptoms can return as the drug wears off, so patients need close observation. It can also precipitate withdrawal or seizures in individuals who are benzodiazepine dependent or in cases of mixed overdoses, so it’s used with caution in the appropriate clinical context. The other agents reverse effects of different drug classes (naloxone for opioids; vitamin K and prothrombin complex concentrate for warfarin anticoagulation), not benzodiazepines.
