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 ) ].

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. ( 1 )

9 DRUG ABUSE AND DEPENDENCE 9.1 Controlled Substance Flurazepam is a Schedule IV controlled substance. 9.2 Abuse Flurazepam hydrochloride capsules are a benzodiazepine and a CNS depressant with a potential for abuse and addiction. Abuse is the intentional, non-therapeutic use of a drug, even once, for its desirable psychological or physiological effects. Misuse is the intentional use, for therapeutic purposes, of a drug by an individual in a way other than prescribed by a health care provider or for whom it was not prescribed. Drug addiction is a cluster of behavioral, cognitive, and physiological phenomena that may include a strong desire to take the drug, difficulties in controlling drug use (e.g., continuing drug use despite harmful consequences, giving a higher priority to drug use than other activities and obligations), and possible tolerance or physical dependence. Even taking benzodiazepines as prescribed may put patients at risk for abuse and misuse of their medication. Abuse and misuse may lead to addiction. Abuse and misuse of benzodiazepines often (but not always) involve the use of doses greater than the maximum recommended dosage and commonly involve concomitant use of other medications, alcohol, and/or illicit substances, which is associated with an increased frequency of serious adverse outcomes, including respiratory depression, overdose, or death. Benzodiazepines are often sought by individuals who abuse drugs and other substances, and by individuals with addictive disorders [see Warnings and Precautions ( 5.2 )] . The following adverse reactions have occurred with benzodiazepine abuse and/or misuse: abdominal pain, amnesia, anorexia, anxiety, aggression, ataxia, blurred vision, confusion, depression, disinhibition, disorientation, dizziness, euphoria, impaired concentration and memory, indigestion, irritability, muscle pain, slurred speech, tremors, and vertigo. The following severe adverse reactions have occurred with benzodiazepine abuse and/or misuse: delirium, paranoia, suicidal ideation and behavior, seizures, coma, breathing difficulty, and death. Death is more often associated with polysubstance use (especially benzodiazepines with other CNS depressants such as opioids and alcohol) . 9.3 Dependence Physical Dependence: Flurazepam hydrochloride capsules may produce physical dependence from continued therapy. Physical dependence is a state that develops as a result of physiological adaptation in response to repeated drug use, manifested by withdrawal signs and symptoms after abrupt discontinuation or a significant dose reduction of a drug. Abrupt discontinuation or rapid dosage reduction of benzodiazepines or administration of flumazenil, a benzodiazepine antagonist, may precipitate acute withdrawal reactions, including seizures, which can be life- threatening. Patients at an increased risk of withdrawal adverse reactions after benzodiazepine discontinuation or rapid dosage reduction include those who take higher dosages (i.e., higher and/or more frequent doses) and those who have had longer durations of use [see Warnings and Precautions ( 5.3 )]. 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 )]. Acute Withdrawal Signs and Symptoms: Acute withdrawal signs and symptoms associated with benzodiazepines have included abnormal involuntary movements, anxiety, blurred vision, depersonalization, depression, derealization, dizziness, fatigue, gastrointestinal adverse reactions (e.g., nausea, vomiting, diarrhea, weight loss, decreased appetite), headache, hyperacusis, hypertension, irritability, insomnia, memory impairment, muscle pain and stiffness, panic attacks, photophobia, restlessness, tachycardia, and tremor. More severe acute withdrawal signs and symptoms, including life-threatening reactions, have included catatonia, convulsions, delirium tremens, depression, hallucinations, mania, psychosis, seizures, and suicidality. Protracted Withdrawal Syndrome: Protracted withdrawal syndrome associated with benzodiazepines is characterized by anxiety, cognitive impairment, depression, insomnia, formication, motor symptoms (e.g., weakness, tremor, muscle twitches), paresthesia, and tinnitus that persists beyond 4 to 6 weeks after initial benzodiazepine withdrawal. Protracted withdrawal symptoms may last weeks to more than 12 months . As a result, there may be difficulty in differentiating withdrawal symptoms from potential re-emergence or continuation of symptoms for which the benzodiazepine was being used. Tolerance: Tolerance to flurazepam hydrochloride capsules may develop from continued therapy. Tolerance is a physiological state characterized by a reduced response to a drug after repeated administration (i.e., a higher dose of a drug is required to produce the same effect that was once obtained at a lower dose). Tolerance to the therapeutic effect of flurazepam hydrochloride capsules may develop; however, little tolerance develops to the amnestic reactions and other cognitive impairments caused by benzodiazepines.

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 (1-800-222-1222), poisoncontrol.org , or a medical toxicologist for additional overdosage management recommendations.

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.

12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Flurazepam, like other central nervous system agents of the 1,4-benzodiazepine class, presumably exerts its effects by binding to stereo-specific receptors at several sites within the central nervous system (CNS). The exact mechanism of action is unknown. 12.3 Pharmacokinetics Flurazepam hydrochloride is rapidly absorbed from the gastro-intestinal tract. Flurazepam is rapidly metabolized and is excreted primarily in the urine. Following a single oral dose, peak flurazepam plasma concentrations ranging from 0.5 to 4.0 ng/mL occur at 30 to 60 minutes post-dosing. The harmonic mean apparent half-life of flurazepam is 2.3 hours. The blood level profile of flurazepam and its major metabolites was determined in man following the oral administration of 30 mg daily for 2 weeks. The N1-hydroxyethyl-flurazepam was measurable only during the early hours after a 30 mg dose and was not detectable after 24 hours. The major metabolite in blood was N1-desalkyl-flurazepam, which reached steady-state (plateau) levels after 7 to 10 days of dosing, at levels approximately 5- to 6-fold greater than the 24-hour levels observed on Day 1. The half-life of elimination of N1-desalkyl-flurazepam ranged from 47 to 100 hours. The major urinary metabolite is conjugated N1-hydroxyethyl-flurazepam which accounts for 22% to 55% of the dose. Less than 1% of the dose is excreted in the urine as N1-desalkyl-flurazepam. This pharmacokinetic profile may be responsible for the clinical observation that flurazepam is increasingly effective on the second or third night of consecutive use and that for 1 or 2 nights after the drug is discontinued both sleep latency and total wake time may still be decreased. The single dose pharmacokinetics of flurazepam were studied in 12 healthy geriatric subjects (aged 61 to 85 years). The mean elimination half-life of desalkyl-flurazepam was longer in elderly male subjects (160 hours) compared with younger male subjects (74 hours), while mean elimination half-life was similar in geriatric female subjects (120 hours) and younger female subjects (90 hours). After multiple dosing, mean steady-state plasma levels of desalkyl-flurazepam were higher in elderly male subjects (81 ng/mL) compared with younger male subjects (53 ng/mL), while values were similar between elderly female subjects (85 ng/mL) and younger female subjects (86 ng/mL). The mean washout half-life of desalkyl-flurazepam was longer in elderly male and female subjects (126 and 158 hours, respectively) compared with younger male and female subjects (111 and 113 hours, respectively). 1 1 Greenblatt DJ, Divoll M, Hammatz JS, MacLauglin DS, Shader RI: Kinetics and clinical effects of flurazepam in young and elderly noninsomniacs.

17 PATIENT COUNSELING INFORMATION Advise the patient to read the FDA-approved patient labeling ( Medication Guide ). Risks from Concomitant Use with Opioids: Advise both patients and caregivers about the risks of potentially fatal respiratory depression and sedation when flurazepam hydrochloride capsules are used with opioids and not to use such drugs concomitantly unless supervised by a healthcare provider [see Warnings and Precautions ( 5.1 ), Drug Interactions ( 7.1 )]. Abuse, Misuse, and Addiction: Inform patients that the use of flurazepam hydrochloride capsules, even at recommended dosages, exposes users to risks of abuse, misuse, and addiction, which can lead to overdose and death, especially when used in combination with other medications (e.g., opioid analgesics), alcohol, and/or illicit substances . Inform patients about the signs and symptoms of benzodiazepine abuse, misuse, and addiction; to seek medical help if they develop these signs and/or symptoms; and on the proper disposal of unused drug [see Warnings and Precautions ( 5.2 ) and Drug Abuse and Dependence ( 9.2 )]. Withdrawal Reactions: Inform patients that the continued use of flurazepam hydrochloride capsules may lead to clinically significant physical dependence and that abrupt discontinuation or rapid dosage reduction of flurazepam hydrochloride capsules may precipitate acute withdrawal reactions, which can be life-threatening. Inform patients that in some cases, patients taking benzodiazepines have developed a protracted withdrawal syndrome with withdrawal symptoms lasting weeks to more than 12 months. Instruct patients that discontinuation or dosage reduction of flurazepam hydrochloride capsules may require a slow taper [see Warnings and Precautions ( 5.3 ) and Drug Abuse and Dependence ( 9.3 )]. CNS Depressant Effects and Next-Day Impairment: Tell patients that flurazepam can cause next-day impairment, even in the absence of symptoms. Caution patients against driving or engaging in other hazardous activities or activities requiring complete mental alertness when using flurazepam. Tell patients that daytime impairment may persist for several days following discontinuation of flurazepam. Advise patients that increased drowsiness and decreased consciousness may increase the risk of falls in some patients [see Warnings and Precautions ( 5.4 )]. Abnormal Thinking and Behavior Change: Instruct patients that sedative hypnotics can cause abnormal thinking and behavior change, including “sleep-driving” and other complex behaviors while not being fully awake (preparing and eating food, making phone calls, or having sex). Tell patients to call you immediately if they develop any of these symptoms [see Warnings and Precautions ( 5.7 )]. Severe Allergic Reactions: Inform patients that severe allergic reactions can occur from flurazepam. Describe the signs/symptoms of these reactions and advise patients to seek medical attention immediately if these occur. Worsening of Depression: Tell patients that flurazepam can worsen depression, and to immediately report any suicidal thoughts [see Warnings and Precautions ( 5.8 )]. Alcohol and Other Drugs: Ask patients about alcohol consumption, medicines they are taking now, and drugs they may be taking without a prescription. Advise patients that alcohol generally should not be used during treatment with flurazepam. Pregnancy: Advise pregnant females that use flurazepam late in pregnancy can result in sedation (respiratory depression, lethargy, hypotonia) and/or withdrawal symptoms (hyperreflexia, irritability, restlessness, tremors, inconsolable crying, and feeding difficulties) in newborns [see Warnings and Precautions ( 5.9 ), Use in Specific Populations ( 8.1 )] . Instruct patients to inform their healthcare provider if they are pregnant. Advise patients that there is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to flurazepam during pregnancy [see Use in Specific Populations ( 8.1 )].

Print Medication Guides at: www.chartwellpharma.com/medguides Medication Guide Flurazepam Hydrochloride Capsules, USP (flur az' e pam hye" droe klor' ide) What is the most important information I should know about flurazepam hydrochloride capsules? Flurazepam hydrochloride capsules are a benzodiazepine medicine. Taking benzodiazepines with opioid medicines, alcohol, or other central nervous system (CNS) depressants (including street drugs) can cause severe drowsiness, breathing problems (respiratory depression), coma and death. Get emergency help right away if any of the following happens: shallow or slowed breathing breathing stops (which may lead to the heart stopping) excessive sleepiness (sedation). Do not drive or operate heavy machinery until you know how taking flurazepam hydrochloride capsules with opioids affect you. Risk of abuse, misuse, and addiction. There is a risk of abuse, misuse, and addiction with benzodiazepines, including flurazepam hydrochloride capsules, which can lead to overdose and serious side effects including coma and death. Serious side effects including coma and death have happened in people who have abused or misused benzodiazepines, including flurazepam hydrochloride capsules. These serious side effects may also include delirium, paranoia, suicidal thoughts or actions, seizures, and difficulty breathing. Call your healthcare provider or go to the nearest hospital emergency room right away if you get any of these serious side effects. You can develop an addiction even if you take flurazepam hydrochloride capsules exactly as prescribed by your healthcare provider. Take flurazepam hydrochloride capsules exactly as your healthcare provider prescribed. Do not share your flurazepam hydrochloride capsules with other people. Keep flurazepam hydrochloride capsules in a safe place and away from children. Physical dependence and withdrawal reactions. Flurazepam hydrochloride capsules can cause physical dependence and withdrawal reactions, especially if you continue to take flurazepam hydrochloride capsules for several days to several weeks. Do not suddenly stop taking flurazepam hydrochloride capsules . Stopping flurazepam hydrochloride capsules suddenly can cause serious and life-threatening side effects, including unusual movements, responses, or expressions, seizures, sudden and severe mental or nervous system changes, depression, seeing or hearing things that others do not see or hear, an extreme increase in activity or talking, losing touch with reality, and suicidal thoughts or actions. Call your healthcare provider or go to the nearest hospital emergency room right away if you get any of these symptoms. Some people who suddenly stop benzodiazepines have symptoms that can last for several weeks to more than 12 months , including anxiety, trouble remembering, learning, or concentrating, depression, problems sleeping, feeling like insects are crawling under your skin, weakness, shaking, muscle twitching, burning or prickling feeling in your hands, arms, legs or feet, and ringing in your ears. Physical dependence is not the same as drug addiction. Your healthcare provider can tell you more about the differences between physical dependence and drug addiction. Do not take more flurazepam hydrochloride capsules than prescribed or take flurazepam hydrochloride capsules for longer than prescribed. After taking flurazepam hydrochloride capsules, you may get up out of bed while not being fully awake and do an activity that you do not know you are doing.

14 CLINICAL STUDIES Sleep laboratory studies have objectively determined that flurazepam hydrochloride capsules are effective for at least 28 consecutive nights of drug administration.

8 USE IN SPECIFIC POPULATIONS 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. Clinical Considerations Fetal/Neonatal Adverse Reactions Benzodiazepines cross the placenta and may produce respiratory depression, hypotonia, and sedation in neonates. Monitor neonates exposed to flurazepam during pregnancy or labor for signs of sedation, respiratory depression, hypotonia, and feeding problems. Monitor neonates exposed to HALCION during pregnancy for signs of withdrawal. Manage these neonates accordingly [see Warnings and Precautions ( 5.9 )]. Data Human Data Published data from observational studies on the use of benzodiazepines during pregnancy do not report a clear association with benzodiazepines and major birth defects. Although early studies reported an increased risk of congenital malformations with diazepam and chlordiazepoxide, there was no consistent pattern noted. In addition, the majority of more recent case-control and cohort studies of benzodiazepine use during pregnancy, which were adjusted for confounding exposures to alcohol, tobacco and other medications, have not confirmed these findings. Animal Data Administration of flurazepam to pregnant animals did not indicate a risk for adverse effects on morphological development at clinically relevant doses; however, animal data for other benzodiazepines suggest that possibility of adverse developmental effects (including long-term effects on neurobehavioral and immunological function) following prenatal exposure. 8.2 Lactation Risk Summary There are no data on the presence of flurazepam in human or animal milk. There are reports of sedation, poor feeding and poor weight gain in infants exposed to benzodiazepines through breast milk. The effects of flurazepam on milk production are unknown. Because of the flurazepam’s long half-life, the potential for flurazepam to accumulate in breast milk, and the potential for serious adverse reactions, including sedation and withdrawal symptoms in breastfed infants, advise patients that breastfeeding is not recommended during treatment with flurazepam. 8.4 Pediatric Use Safety and effectiveness in pediatric patients have not been established. 8.5 Geriatric Use Flurazepam may cause confusion and over-sedation in the elderly. Elderly patients generally should be started on a low dose of flurazepam and observed closely. Elderly or debilitated patients may be more sensitive to benzodiazepines, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.

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 ) ].
