The drug has been used as an antidote in the treatment of benzodiazepine overdoses. It reverses the effects of benzodiazepines by competitive inhibition at the benzodiazepine (BZ) recognition site on the GABA/benzodiazepine receptor complex. There are many complications that must be taken into consideration when used in the acute care setting. These include lowered seizure threshold, agitation, and anxiousness. Flumazenil's short half-life requires multiple doses. Because of the potential risks of withdrawal symptoms and the drug's short half-life, patients must be carefully monitorered to prevent recurrence of overdose symptoms or adverse side effects.
