Boxed 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.

Mechanism of action

Sourced from openFDA

Mechanism-of-action class: GABA A Modulators.

GABA A

Indications

Sourced from openFDA
  • 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.ICD-10: G47.00

Contraindications

Sourced from openFDA
  • 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.contraindicated

Dosage & administration

Sourced from openFDA

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 ) ].

Warnings & precautions

Sourced from openFDA

CNS depressant effects: Impaired alertness and motor coordination, including risk of falling. Daytime impairment. Caution patients against driving and other activities requiring complete mental alertness. ( 5.4 ) The failure of insomnia to remit after 7 to 10 days of treatment may indicate the presence of a primary psychiatric and/or medical illness that should be evaluated. ( 5.5 ) Severe anaphylactic/anaphylactoid reactions: Angioedema and anaphylaxis have been reported. Do not rechallenge if such reactions occur. ( 5.6 ) Sleep driving and other complex behaviors while not fully awake: Risk increases with dose and concomitant CNS depressants and alcohol. Immediately evaluate any new onset behavioral changes. ( 5.7 ) Worsening of depression or suicidal thinking may occur: Prescribe the least number of capsules feasible to avoid intentional overdose. ( 5.8 ) Neonatal Sedation and Withdrawal Syndrome: Flurazepam use during pregnancy can result in neonatal sedation and/or neonatal withdrawal. ( 5.9 ) 5.1 Risks from Concomitant Use of Opioids Concomitant use of benzodiazepines, including flurazepam, and opioids may result in profound sedation, respiratory depression, coma, and death. Because of these risks, reserve concomitant prescribing of benzodiazepines and opioids in patients for whom alternative treatment options are inadequate. Observational studies have demonstrated that concomitant use of opioid analgesics and benzodiazepines increases the risk of drug-related mortality compared to use of opioids alone.

Use in specific populations

Sourced from openFDA

Lactation: Breastfeeding not recommended. ( 8.2 ) 8.1 Pregnancy Pregnancy Exposure Registry: There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to psychiatric medications, including flurazepam, during pregnancy. Healthcare providers are encouraged to register patients by calling the National Pregnancy Registry for Psychiatric Medications at 1-866-961-2388 or visiting online at https://womensmentalhealth.org/pregnancyregistry/ . Risk Summary Neonates born to mothers using benzodiazepines late in pregnancy have been reported to experience symptoms of sedation and/or neonatal withdrawal [ see Warnings and Precautions ( 5.9 ) and Clinical Considerations]. Available data from published observational studies of pregnant women exposed to benzodiazepines do not report a clear association with benzodiazepines and major birth defects (see Data) . The background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively.

Overdosage

Sourced from openFDA

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.
