• What type of medicine is this?

    • Flumazenil belongs to a group of drugs known as benzodiazepine antagonists. You will only get this drug when your healthcare provider prescribes it.
      It starts to work rather quickly but doesn’t work for very long. Dosing will depend on how long the benzodiazepine poison works. Common benzodiazepines include diazepam (Valium), alprazolam (Xanax), and clonazepam (Klonopin).

      Flumazenil is used for:

      • Treating benzodiazepine overdose in adults.
      • Waking up people put to sleep for surgery or other medical procedures in which benzodiazepines are used as a sedative.
    • What is the medicine used for?

    • Flumazenil is a drug that reverses the effect (antidote) of a group of sedative drugs called benzodiazepines. This drug prevents benzodiazepines from getting to the places in the brain where they work because it is better at occupying these places. Flumazenil is injected into the vein. It is a prescription-only medicine and does not work for morphine or similar opioids.
      If you have a known sensitivity to flumazenil, inform your healthcare provider.
