      Mechanism Description
  • Antagonize the effect of Midazolam when combined with Flumazenil 

Recommended Action
      Management The use of flumazenil is not recommended in patients with epilepsy who have been receiving long-term treatment with benzodiazepines. In addition, flumazenil is contraindicated in patients who have received a benzodiazepine to control potentially life-threatening conditions such as status epilepticus or increased intracranial pressure. Extreme caution, dose individualization, and close monitoring is recommended for other patients. Clinicians should be prepared to manage convulsions. Most seizures have been successfully managed with benzodiazepines, phenytoin, or barbiturates.
