⚠ Boxed Warning (Black Box)
WARNING: RISKS FROM CONCOMITANT USE WITH OPIOIDS; ABUSE, MISUSE, AND ADDICTION; and DEPENDENCE AND WITHDRAWAL REACTIONS Concomitant use of benzodiazepines and opioids may result in profound sedation, respiratory depression, coma, and death. Reserve concomitant prescribing of these drugs in patients for whom alternative treatment options are inadequate. Limit dosages and durations to the minimum required. Follow patients for signs and symptoms of respiratory depression and sedation [see Warnings and Precautions ( 5.1 ) and Drug Interactions ( 7.1 ) ]. The use of benzodiazepines, including flurazepam hydrochloride capsules, exposes users to risks of abuse, misuse, and addiction, which can lead to overdose or death. Abuse and misuse of benzodiazepines commonly involve concomitant use of other medications, alcohol, and/or illicit substances, which is associated with an increased frequency of serious adverse outcomes. Before prescribing flurazepam hydrochloride capsules, and throughout treatment, assess each patient’s risk for abuse, misuse, and addiction [ see Warnings and Precautions ( 5.2 ) ]. The continued use of benzodiazepines, including flurazepam hydrochloride capsules, may lead to clinically significant physical dependence. The risks of dependence and withdrawal increase with longer treatment duration and higher daily dose. Abrupt discontinuation or rapid dosage reduction of flurazepam hydrochloride capsules after continued use may precipitate acute withdrawal reactions, which can be life-threatening. To reduce the risk of withdrawal reactions, use a gradual taper to discontinue flurazepam hydrochloride capsules or reduce the dosage [ see Dosage and Administration ( 2.3 ) and Warnings and Precautions ( 5.3 ) ].

What Is Flurazepam Hydrochloride Used For?
1 INDICATIONS AND USAGE Flurazepam hydrochloride capsules are indicated for the treatment of insomnia characterized by difficulty in falling asleep, frequent nocturnal awakenings, and/or early morning awakenings [see Clinical Studies ( 14 ) ]. Since insomnia is often transient and intermittent, short-term use is usually sufficient. Prolonged use of hypnotics is usually not indicated and should only be undertaken concomitantly with appropriate evaluation of the patient. Flurazepam, a gamma-aminobutyric (GABA A ) agonist, is indicated for the treatment of insomnia characterized by difficulty falling asleep, frequent nocturnal awakenings, and/or early morning awakenings.

Dosage and Administration
2 DOSAGE AND ADMINISTRATION Use the lowest dose effective for the patient. Recommended initial dose is 15 mg for women and 15 mg or 30 mg for men. ( 2.1 ) Elderly or debilitated patients: recommended dose is 15 mg. ( 2.2 ) 2.1 Dosage in Adults Use the lowest dose effective for the patient, as important adverse effects of flurazepam hydrochloride capsules are dose related. The recommended initial dose is 15 mg for women and either 15 mg or 30 mg for men. The 15 mg dose can be increased to 30 mg if necessary for efficacy. The recommended initial doses for women and men are different because flurazepam clearance is lower in women [see Pharmacokinetics ( 12.3 ) ]. 2.2 Dosage in Elderly or Debilitated Patients Elderly or debilitated patients may be especially sensitive to flurazepam. Since the risk of the development of oversedation, dizziness, confusion and/or ataxia increases substantially with larger doses in elderly or debilitated patients, it is recommended that in such patients the dosage be limited to 15 mg. Staggering and falling have also been reported, particularly in geriatric patients [see Warnings and Precautions ( 5.2 ) ]. 2.3 Discontinuation or Dosage Reduction of Flurazepam Hydrochloride Capsules To reduce the risk of withdrawal reactions, use a gradual taper to discontinue flurazepam hydrochloride capsules or reduce the dosage. If a patient develops withdrawal reactions, consider pausing the taper or increasing the dosage to the previous tapered dosage level. Subsequently decrease the dosage more slowly [ see Warnings and Precautions ( 5.3 ) and Drug Abuse and Dependence ( 9.3 ) ].

Drug Interactions
7 DRUG INTERACTIONS Concomitant use of benzodiazepines and opioids may result in profound sedation, respiratory depression, and death. ( 7.1 ) CNS Depressants: Downward dose adjustment may be necessary due to additive effects. ( 7.2 ) 7.1 Opioids The concomitant use of benzodiazepines and opioids increases the risk of respiratory depression because of actions at different receptor sites in the CNS that control respiration. Benzodiazepines interact at GABA A sites, and opioids interact primarily at mu receptors. When benzodiazepines and opioids are combined, the potential for benzodiazepines to significantly worsen opioid-related respiratory depression exists. Limit dosage and duration of concomitant use of benzodiazepines and opioids, and follow patients closely for respiratory depression and sedation. 7.2 CNS Depressants Benzodiazepines, including flurazepam, produce additive CNS depressant effects when co-administered with ethanol or other CNS depressants (e.g., psychotropic medications, anticonvulsants, antihistamines). Downward dose adjustment of flurazepam and/or concomitant CNS depressants may be necessary because of additive effects.
Contraindications
4 CONTRAINDICATIONS Flurazepam hydrochloride capsules are contraindicated in patients with known hypersensitivity to flurazepam or other benzodiazepines. Rare cases of angioedema involving the tongue, glottis or larynx have been reported in patients after taking the first or subsequent doses of flurazepam. Some patients have had additional symptoms such as dyspnea, throat closing, or nausea and vomiting that suggest anaphylaxis. Patients who develop such reactions should not be rechallenged with flurazepam. Hypersensitivity to flurazepam or other benzodiazepines. ( 4 )
Overdosage
10 OVERDOSAGE Overdosage of benzodiazepines is characterized by central nervous system depression ranging from drowsiness to coma. In mild to moderate cases, symptoms can include drowsiness, confusion, dysarthria, lethargy, hypnotic state, diminished reflexes, ataxia, and hypotonia. Rarely, paradoxical or disinhibitory reactions (including agitation, irritability, impulsivity, violent behavior, confusion, restlessness, excitement, and talkativeness) may occur. In severe overdosage cases, patients may develop respiratory depression and coma. Overdosage of benzodiazepines in combination with other CNS depressants (including alcohol and opioids) may be fatal [see Warnings and Precautions ( 5.2 )] . Markedly abnormal (lowered or elevated) blood pressure, heart rate, or respiratory rate raise the concern that additional drugs and/or alcohol are involved in the overdosage. In managing benzodiazepine overdosage, employ general supportive measures, including intravenous fluids and airway management. Flumazenil, a specific benzodiazepine receptor antagonist indicated for the complete or partial reversal of the sedative effects of benzodiazepines in the management of benzodiazepine overdosage, can lead to withdrawal and adverse reactions, including seizures, particularly in the context of mixed overdosage with drugs that increase seizure risk (e.g., tricyclic and tetracyclic antidepressants) and in patients with long-term benzodiazepine use and physical dependency. The risk of withdrawal seizures with flumazenil use may be increased in patients with epilepsy. Flumazenil is contraindicated in patients who have received a benzodiazepine for control of a potentially life-threatening condition (e.g., status epilepticus). If the decision is made to use flumazenil, it should be used as an adjunct to, not as a substitute for, supportive management of benzodiazepine overdosage. See the flumazenil injection Prescribing Information. Consider contacting a poison center...
