Boxed Warning

openFDA Drug Labeling

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 ). The use of benzodiazepines, including Restoril, 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 Restoril and throughout treatment, assess each patient’s risk for abuse, misuse, and addiction ( see WARNINGS ). The continued use of benzodiazepines, including Restoril, 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 Restoril 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 Restoril or reduce the dosage ( see DOSAGE AND ADMINISTRATION and WARNINGS ).

Indications and Usage

openFDA Drug Labeling

INDICATIONS AND USAGE Restoril ® (temazepam) is indicated for the short-term treatment of insomnia (generally 7 to 10 days). For patients with short-term insomnia, instructions in the prescription should indicate that Restoril ® (temazepam) should be used for short periods of time (7 to 10 days). The clinical trials performed in support of efficacy were 2 weeks in duration with the final formal assessment of sleep latency performed at the end of treatment.

Dosage and Administration

openFDA Drug Labeling

DOSAGE AND ADMINISTRATION While the recommended usual adult dose is 15 mg before retiring, 7.5 mg may be sufficient for some patients, and others may need 30 mg. In transient insomnia, a 7.5 mg dose may be sufficient to improve sleep latency. In elderly or debilitated patients, it is recommended that therapy be initiated with 7.5 mg until individual responses are determined. Discontinuation or Dosage Reduction of Restoril To reduce the risk of withdrawal reactions, use a gradual taper to discontinue Restoril 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, Dependence and Withdrawal Reactions and DRUG ABUSE AND DEPENDENCE: Dependence ).

WARNINGS Risks from Concomitant Use with Opioids Concomitant use of benzodiazepines, including Restoril, and opioids may result in profound sedation, respiratory depression, coma, and death. Because of these risks, reserve concomitant prescribing of these drugs 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. If a decision is made to prescribe Restoril concomitantly with opioids, prescribe the lowest effective dosages and minimum durations of concomitant use, and follow patients closely for signs and symptoms of respiratory depression and sedation. In patients already receiving an opioid analgesic, prescribe a lower initial dose of Restoril than indicated in the absence of an opioid and titrate based on clinical response. If an opioid is initiated in a patient already taking Restoril, prescribe a lower initial dose of the opioid and titrate based upon clinical response. Advise both patients and caregivers about the risks of respiratory depression and sedation when Restoril is used with opioids. Advise patients not to drive or operate heavy machinery until the effects of concomitant use with the opioid have been determined ( see PRECAUTIONS, Drug Interactions ). Abuse, Misuse, and Addiction The use of benzodiazepines, including Restoril, exposes users to the risks of abuse, misuse, and addiction, which can lead to overdose or death. 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 ( see DRUG ABUSE AND DEPENDENCE, Abuse ). Before prescribing Restoril and throughout treatment, assess each patient’s risk for abuse, misuse, and addiction (e.g., using a standardized screening tool). Use of Restoril, particularly in patients at elevated risk, necessitates counseling about the risks and proper use of Restoril along with monitoring for signs and symptoms of abuse, misuse, and addiction. Prescribe the lowest effective dosage; avoid or minimize concomitant use of CNS depressants and other substances associated with abuse, misuse, and addiction (e.g., opioid analgesics, stimulants); and advise patients on the proper disposal of unused drug. If a substance use disorder is suspected, evaluate the patient and institute (or refer them for) early treatment, as appropriate. Dependence and Withdrawal Reactions To reduce the risk of withdrawal reactions, use a gradual taper to discontinue Restoril or reduce the dosage (a patient-specific plan should be used to taper the dose) ( see DOSAGE AND ADMINISTRATION, Discontinuation or Dosage Reduction of Restoril ). Patients at an increased risk of withdrawal adverse reactions after benzodiazepine discontinuation or rapid dosage reduction include those who take higher dosages, and those who have had longer durations of use. Acute Withdrawal Reactions The continued use of benzodiazepines, including Restoril, may lead to clinically significant physical dependence. Abrupt discontinuation or rapid dosage reduction of Restoril after continued use, or administration of flumazenil (a benzodiazepine antagonist) may precipitate acute withdrawal reactions, which can be life-threatening (e.g., seizures) ( see DRUG ABUSE AND DEPENDENCE, Dependence ). Protracted Withdrawal Syndrome In some cases, benzodiazepine users have developed a protracted withdrawal syndrome with withdrawal symptoms lasting weeks to more than 12 months ( see DRUG ABUSE AND DEPENDENCE, Dependence ). Sleep disturbance may be the presenting manifestation of an underlying physical and/or psychiatric disorder. Consequently, a decision to initiate symptomat …

Adverse Reactions

openFDA Drug Labeling

ADVERSE REACTIONS During controlled clinical studies in which 1076 patients received Restoril at bedtime, the drug was well tolerated. Side effects were usually mild and transient. Adverse reactions occurring in 1% or more of patients are presented in the following table: Restoril % Incidence (n=1076) Placebo % Incidence (n=783) Drowsiness 9.1 5.6 Headache 8.5 9.1 Fatigue 4.8 4.7 Nervousness 4.6 8.2 Lethargy 4.5 3.4 Dizziness 4.5 3.3 Nausea 3.1 3.8 Hangover 2.5 1.1 Anxiety 2.0 1.5 Depression 1.7 1.8 Dry Mouth 1.7 2.2 Diarrhea 1.7 1.1 Abdominal Discomfort 1.5 1.9 Euphoria 1.5 0.4 Weakness 1.4 0.9 Confusion 1.3 0.5 Blurred Vision 1.3 1.3 Nightmares 1.2 1.7 Vertigo 1.2 0.8 The following adverse events have been reported less frequently (0.5% to 0.9%): Central Nervous System – anorexia, ataxia, equilibrium loss, tremor, increased dreaming Cardiovascular – dyspnea, palpitations Gastrointestinal – vomiting Musculoskeletal – backache Special Senses – hyperhidrosis, burning eyes Amnesia, hallucinations, horizontal nystagmus, and paradoxical reactions including restlessness, overstimulation and agitation were rare (less than 0.5%).

Drug Interactions

openFDA Drug Labeling

Drug Interactions 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 GABAA 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 monitor patients closely for respiratory depression and sedation. The benzodiazepines, including temazepam, produce additive CNS-depressant effects when co-administered with other CNS depressants such as alcohol, barbiturates, antipsychotics, sedative/hypnotics, anxiolytics, antidepressants, narcotic analgesics, sedative antihistamines, anticonvulsants, and anesthetics. The pharmacokinetic profile of temazepam does not appear to be altered by orally administered cimetidine dosed according to labeling.

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, Abuse, Misuse, and Addiction ). 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 the Poison Help line (1-800-221-2222) or a medical toxicologist for additional overdosage management recommendations.

A report count is not a risk measure. FAERS accepts voluntary and mandatory reports without establishing causation, and reporting is influenced by how widely a drug is used, how long it has been marketed, and media attention. FDA states that reports “do not prove that the drug caused the event”. Compare rates, not totals.

Attributed to this product's most-reported active ingredient: TEMAZEPAM. Combination products with more than six active ingredients are not attributed, because a report count summed across a long ingredient list measures the list, not the medicine.
