THESE ARE MOST FREQUENT IN PATIENTS WHO HAVE BEEN ON BENZODIAZEPINES FOR LONG-TERM SEDATION OR IN OVERDOSE CASES WHERE PATIENTS ARE SHOWING SIGNS OF SERIOUS CYCLIC ANTIDEPRESSANT OVERDOSE.

…Flumazenil is contraindicated: in patients with a known hypersensitivity to flumazenil or benzodiazepines. in patients who have been given a benzodiazepine for control of a potentially life-threatening condition (e.g., control of intracranial pressure or status epilepticus). in patients who are showing signs of serious cyclic antidepressant overdose (see WARNINGS ).

Flumazenil is not recommended in cases of serious cyclic antidepressant poisoning, as manifested by motor abnormalities (twitching, rigidity, focal seizure), dysrhythmia (wide QRS, ventricular dysrhythmia, heart block), anticholinergic signs (mydriasis, dry mucosa, hypoperistalsis), and cardiovascular collapse at presentation.

Possible risk factors for seizures include: concurrent major sedative-hypnotic drug withdrawal, recent therapy with repeated doses of parenteral benzodiazepines, myoclonic jerking or seizure activity prior to flumazenil administration in overdose cases, or concurrent cyclic antidepressant poisoning.

In such cases flumazenil should be withheld and the patient should be allowed to remain sedated (with ventilatory and circulatory support as needed) until the signs of antidepressant toxicity have subsided.

CNS Depressants: RALDESY may enhance effects of alcohol, barbiturates, or other CNS depressants ( 7 ).

Central Nervous System (CNS) Depressants Clinical Impact: RALDESY may enhance the response CNS depressants.

Intervention: Patients should be counseled that RALDESY may enhance the response to alcohol, barbiturates, and other CNS depressants.
