Flumazenil is a benzodiazepine receptor antagonist that can reverse the effects of benzodiazepines, although its use following benzodiazepine overdose is controversial. Medical observation and supportive care are the mainstay of treatment of benzodiazepine overdose. [16]
Many benzodiazepines (including midazolam) have longer half-lives than flumazenil. Therefore, in cases of overdose, repeated doses of flumazenil may be required to prevent recurrent symptoms once the initial dose of flumazenil wears off. [citation needed] It is hepatically metabolised to inactive compounds which are excreted in the urine.
Flumazenil raises concerns with its tendency to induce benzodiazepine withdrawal, and symptoms include seizures and agitation. When a patient overdoses intentionally, benzodiazepines can actually mediate the effects of other lethal drugs in the system, so flumazenil's action to reverse its effects can actually be harmful.
The antidote for an overdose of diazepam (or any other benzodiazepine) is flumazenil (Anexate). This drug is only used in cases with severe respiratory depression or cardiovascular complications. Because flumazenil is a short-acting drug, and the effects of diazepam can last for days, several doses of flumazenil may be necessary.
The toxicity of benzodiazepine overdose and the risk of death are also increased in the elderly and those with obstructive pulmonary disease or when used intravenously. Treatment is supportive; activated charcoal can be used within an hour of the overdose. The antidote for an overdose of midazolam (or any other benzodiazepine) is flumazenil. [41]
Flumazenil delivered via slow subcutaneous infusion represents a safe procedure for those withdrawing from long-term, high dose benzodiazepine dependency. [61] It has a low risk of seizures even amongst those who have experienced convulsions when previously attempting benzodiazepine withdrawal.

The various benzodiazepines differ in their toxicity; temazepam appears most toxic in overdose and when used with other drugs. [165] [166] The symptoms of a benzodiazepine overdose may include; drowsiness, slurred speech, nystagmus, hypotension, ataxia, coma, respiratory depression, and cardiorespiratory arrest. [163]
