CLORAZEPATE DIPOTASSIUM by is a Prescription medication manufactured, distributed, or labeled by Aurolife Pharma, LLC, Aurolife Pharma LLC, Alphapharm Pty. Ltd.. Drug facts, warnings, and ingredients follow.
Chemically, Clorazepate dipotassium is a benzodiazepine. The empirical formula is C16H11ClK2N2O4; the molecular weight is 408.92; 1H-1, 4 Benzodiazepine-3-carboxylic acid, 7-chloro-2,3-dihydro-2-oxo-5-phenyl-, potassium salt compound with potassium hydroxide (1:1) and the structural formula may be represented as follows:

The compound occurs as a fine, light yellow, practically odorless powder. It is insoluble in the common organic solvents, but very soluble in water. Aqueous solutions are unstable, clear, light yellow, and alkaline.
Clorazepate dipotassium tablets, USP contain 3.75 mg, 7.5 mg or 15 mg of clorazepate dipotassium, USP for oral administration.
Inactive ingredients for Clorazepate dipotassium tablets: croscarmellose sodium, magnesium oxide, magnesium stearate, microcrystalline cellulose, potassium carbonate, sodium chloride and sodium lauryl sulfate. The 3.75 mg tablets also contain FD&C Blue No. 2 Aluminum Lake and the 7.5 mg tablets also contain FD&C Yellow No. 6 Aluminum Lake.
Pharmacologically, clorazepate dipotassium has the characteristics of the benzodiazepines. It has depressant effects on the central nervous system. The primary metabolite, nordiazepam, quickly appears in the blood stream. The serum half-life is about 2 days. The drug is metabolized in the liver and excreted primarily in the urine.
Studies in healthy men have shown that clorazepate dipotassium has depressant effects on the central nervous system. Prolonged administration of single daily doses as high as 120 mg was without toxic effects. Abrupt cessation of high doses was followed in some patients by nervousness, insomnia, irritability, diarrhea, muscle aches, or memory impairment.
Since orally administered clorazepate dipotassium is rapidly decarboxylated to form nordiazepam, there is essentially no circulating parent drug. Nordiazepam, the primary metabolite, quickly appears in the blood and is eliminated from the plasma with an apparent half-life of about 40 to 50 hours. Plasma levels of nordiazepam increase proportionally with Clorazepate dipotassium tablets dose and show moderate accumulation with repeated administration. The protein binding of nordiazepam in plasma is high (97-98%).
Within 10 days after oral administration of a 15 mg (50 µCi) dose of 14C-Clorazepate dipotassium tablets to two volunteers, 62-67% of the radioactivity was excreted in the urine and 15-19% was eliminated in the feces. Both subjects were still excreting measurable amounts of radioactivity in the urine (about 1% of the 14C-dose) on day ten.
Nordiazepam is further metabolized by hydroxylation. The major urinary metabolite is conjugated oxazepam (3-hydroxynordiazepam), and smaller amounts of conjugated p-hydroxynordiazepam and nordiazepam are also found in the urine.
Clorazepate dipotassium tablets are indicatedfor the management of anxiety disordersorfortheshort-term relief of the symptoms of anxiety. Anxiety or tensionassociatedwith the stress of everyday life usually does not require treatmentwith an anxiolytic.
Clorazepate dipotassium tablets are indicated as adjunctivetherapy in themanagement of partialseizures.
Theeffectiveness of Clorazepate dipotassium tablets in long-term management of anxiety, that is,more than 4 months, has not beenassessed by systematicclinicalstudies.Long-term studies in epilepticpatients,however, have showncontinuedtherapeuticactivity.Thephysician should reassessperiodically the usefulnessof the drug for the individualpatient.
Clorazepate dipotassium tabletsare indicatedfor the symptomaticrelief of acute alcoholwithdrawal.
Risks from Concomitant Use with Opioids: Concomitant use of benzodiazepines, including Clorazepate dipotassium tablets, 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 Clorazepate dipotassium tablets 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 Clorazepate dipotassium tablets than indicated in the absence of an opioid and titrate based on clinical response. If an opioid is initiated in a patient already taking Clorazepate dipotassium tablets, 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 Clorazepate dipotassium tablets 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 Clorazepate dipotassium tablets, 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 Clorazepate dipotassium tablets and throughout treatment, assess each patient’s risk for abuse, misuse, and addiction (e.g., using a standardized screening tool). Use of Clorazepate dipotassium tablets, particularly in patients at elevated risk, necessitates counseling about the risks and proper use of Clorazepate dipotassium tablets 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 Clorazepate dipotassium tablets or reduce the dosage (a patient-specific plan should be used to taper the dose) (see DOSAGE AND ADMINISTRATION: Discontinuation of Dosage Reduction of Clorazepate dipotassium tablets).
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 Clorazepate dipotassium tablets, may lead to clinically significant physical dependence. Abrupt discontinuation or rapid dosage reduction of Clorazepate dipotassium tablets 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).
Use in DepressiveNeuroses or PsychoticReactions:Clorazepate dipotassium tablets are notrecommendedfor use in depressive neuroses orinpsychotic reactions.
Use in Children:Becauseof the lack of sufficientclinicalexperience,Clorazepate dipotassium tablets are not recommended for use in patientslessthan 9 years of age.
Interferencewith PsychomotorPerformance: PatientstakingClorazepate dipotassium tablets should be cautionedagainstengaging in hazardousoccupations requiringmental alertness,such as operatingdangerousmachineryincludingmotorvehicles.
ConcomitantUsewithCNSDepressants:SinceClorazepate dipotassium tablets has a centralnervous system depressanteffect,patients should be advisedagainst the simultaneous use of other CNSdepressantdrugs, and cautioned that the effectsof alcohol may be increased.
Suicidal Behavior and Ideation: Antiepileptic drugs (AEDs), including Clorazepate dipotassium tablets, increase the risk of suicidal thoughts or behavior in patients taking these drugs for any indication. Patients treated with any AED for any indication should be monitored for the emergence or worsening of depression, suicidal thoughts or behavior, and/or any unusual changes in mood or behavior.
Pooled analyses of 199 placebo-controlled clinical trials (mono- and adjunctive therapy) of 11 different AEDs showed that patients randomized to one of the AEDs had approximately twice the risk (adjusted Relative Risk 1.8, 95% CI:1.2, 2.7) of suicidal thinking or behavior compared to patients randomized to placebo. In these trials, which had a median treatment duration of 12 weeks, the estimated incidence rate of suicidal behavior or ideation among 27,863 AED-treated patients was 0.43%, compared to 0.24% among 16,029 placebo-treated patients, representing an increase of approximately one case of suicidal thinking or behavior for every 530 patients treated. There were four suicides in drug-treated patients in the trials and none in placebo-treated patients, but the number is too small to allow any conclusion about drug effect on suicide.
The increased risk of suicidal thoughts or behavior with AEDs was observed as early as one week after starting drug treatment with AEDs and persisted for the duration of treatment assessed. Because most trials included in the analysis did not extend beyond 24 weeks, the risk of suicidal thoughts or behavior beyond 24 weeks could not be assessed.
The risk of suicidal thoughts or behavior was generally consistent among drugs in the data analyzed. The finding of increased risk with AEDs of varying mechanisms of action and across a range of indications suggests that the risk applies to all AEDs used for any indication. The risk did not vary substantially by age (5-100 years) in the clinical trials analyzed. Table 1 shows absolute and relative risk by indication for all evaluated AEDs.
| Indication
| Placebo Patients with EventsPer 1000 Patients | Drug Patients with Events Per 1000 Patients
| Relative Risk: Incidence of Events in Drug Patients/Incidence in Placebo Patients
| Risk Difference: Additional Drug Patients with Events Per1000 Patients
|
| Epilepsy | 1.0 | 3.4 | 3.5 | 2.4 |
| Psychiatric | 5.7 | 8.5 | 1.5 | 2.9 |
| Other | 1.0 | 1.8 | 1.9 | 0.9 |
| Total | 2.4 | 4.3 | 1.8 | 1.9 |
The relative risk for suicidal thoughts or behavior was higher in clinical trials for epilepsy than in clinical trials for psychiatric or other conditions, but the absolute risk differences were similar for the epilepsy and psychiatric indications.
Anyone considering prescribing Clorazepate dipotassium tablets or any other AED must balance the risk of suicidal thoughts or behavior with the risk of untreated illness. Epilepsy and many other illnesses for which AEDs are prescribed are themselves associated with morbidity and mortality and an increased risk of suicidal thoughts and behavior. Should suicidal thoughts and behavior emerge during treatment, the prescriber needs to consider whether the emergence of these symptoms in any given patient may be related to the illness being treated.
Patients, their caregivers, and families should be informed that AEDs increase the risk of suicidal thoughts and behavior and should be advised of the need to be alert for the emergence or worsening of the signs and symptoms of depression, any unusual changes in mood or behavior, or the emergence of suicidal thoughts, behavior, or thoughts about self- harm. Behaviors of concern should be reported immediately to healthcare providers.
Neonatal Sedation and Withdrawal Syndrome: Use of Clorazepate dipotassium tablets 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 the neonate (see PRECAUTIONS: Pregnancy). Monitor neonates exposed to Clorazepate dipotassium during pregnancy or labor for signs of sedation and monitor neonates exposed to Clorazepate dipotassium during pregnancy for signs of withdrawal; manage these neonates accordingly.
In those patients in which a degree of depression accompanies the anxiety,suicidaltendencies may be present and protectivemeasuresmay be required.Theleastamount of drug that is feasibleshould be available to the patient.
PatientstakingClorazepate dipotassium tablets forprolonged periods should have blood counts andliverfunctiontestsperiodically.The usual precautions in treatingpatientswithimpairedrenal or hepaticfunctionshould also be observed.
In elderlyor debilitatedpatients,the initialdoseshould be small, and increments should be made gradually, in accordancewith the response of the patient, to precludeataxia or excessivesedation.
Advise thepatient to read theFDA-approvedpatientlabeling (Medication Guide).
Advise both patients and caregivers about the risks of potentially fatal respiratory depression and sedation when Clorazepate dipotassium tablets is used with opioids and not to use such drugs concomitantly unless supervised by a health care provider. Advise patients not to drive or operate heavy machinery until the effects of concomitant use with the opioid have been determined (see WARNINGS, Risks from Concomitant Use with Opioids and PRECAUTIONS, Drug Interactions).
Abuse, Misuse, and Addiction: Inform patients that the use of Clorazepate dipotassium tablets, 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 DRUG ABUSE AND DEPENDENCE).
Withdrawal Reactions: Inform patients that the continued use of Clorazepate dipotassium tablets may lead to clinically significant physical dependence and that abrupt discontinuation or rapid dosage reduction of Clorazepate dipotassium tablets 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 Clorazepate dipotassium tablets may require a slow taper (see WARNINGS and DRUG ABUSE AND DEPENDENCE).
Suicidal Thinking and Behavior: Patients, their caregivers, and families should be counseled that AEDs, including Clorazepate dipotassium tablets, may increase the risk of suicidal thoughts and behavior and should be advised of the need to be alert for the emergence or worsening of symptoms of depression, any unusual changes in mood or behavior, or the emergence of suicidal thoughts, behavior, or thoughts about self-harm. Behaviors of concern should be reported immediately to healthcare providers.
Pregnancy: Advise pregnant females that use of Clorazepate dipotassium tablets 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, Neonatal Sedation and Withdrawal Syndrome and Precautions, Pregnancy). 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 Clorazepate dipotassium tablets during pregnancy (see Precautions, Pregnancy).
Nursing: Advise patients that breastfeeding is not recommended during treatment with Clorazepate dipotassium tablets (see Precautions, Nursing Mothers).
Theconcomitant use of benzodiazepines and opioidsincreases the riskof respiratorydepressionbecause of actionsatdifferentreceptor sites in the CNS that control respiration.Benzodiazepinesinteract at GABAA sites and opioidsinteractprimarilyatmu receptors. Whenbenzodiazepinesand opioids arecombined, the potentialforbenzodiazepinestosignificantlyworsenopioid-relatedrespiratorydepressionexists.Limitdosageandduration of concomitant use of benzodiazepines and opioids, and monitorpatients closelyforrespiratorydepressionandsedation.
If Clorazepate dipotassium tablets is to be combined with other drugs acting on the central nervous system, careful consideration should be given to thepharmacology of the agentsto be employed.Animalexperienceindicates that clorazepatedipotassium prolongs thesleepingtimeafterhexobarbital or afterethylalcohol,increases the inhibitoryeffects of chlorpromazine, but does not exhibitmonoamineoxidaseinhibition.Clinicalstudies have shownincreasedsedationwithconcurrent hypnotic medications.Theactions of the benzodiazepines may be potentiated by barbiturates,narcotics,phenothiazines,monoamine oxidase inhibitors or other antidepressants.
If Clorazepate dipotassium tablets are used to treatanxietyassociatedwithsomatic disease states,carefulattentionmust be paid to possible druginteractionwith concomitantmedication.

Pregnancy Exposure Registry
There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to psychiatric medications, including Clorazepate dipotassium tablets, during pregnancy. Healthcare providers are encouraged to register patients 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: Neonatal Sedation and Withdrawal Syndrome 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 Clorazepate dipotassium during pregnancy or labor for signs of sedation, respiratory depression, hypotonia, and feeding problems. Monitor neonates exposed to Clorazepate dipotassium during pregnancy for signs of withdrawal. Manage these neonates accordingly (see WARNINGS: Neonatal Sedation and Withdrawal Syndrome).
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
In animal reproduction studies, oral administration of clorazepate to pregnant rats and rabbits at doses up to 150 and 15 mg/kg, respectively, did not cause fetal toxicities or malformation. However, the sedative effects of high dose clorazepate interfered with the maternal care of the offspring.
Risk Summary
Clorazepate and its active metabolite, nordiazepam, are present in breast milk. There are reports of sedation, poor feeding and poor weight gain in infants exposed to benzodiazepines through breast milk. The effects of clorazepate on milk production are unknown. Because of the potential for serious adverse reactions, including sedation and withdrawal symptoms in infants, advise patients that breastfeeding is not recommended during treatment with Clorazepate dipotassium.
Geriatric Use: Clinical studies of Clorazepate dipotassium tablets were not adequate to determine whether subjects aged 65 and over respond differently than younger subjects. Elderly or debilitated patients may be especially sensitive to the effects of all benzodiazepines, including Clorazepate dipotassium. In general, elderly or debilitated patients should be started on lower doses of Clorazepate dipotassium and observed closely, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and concomitant disease or other drug therapy. Dose adjustments should also be made slowly, and with more caution in this patient population (see PRECAUTIONS and DOSAGE AND ADMINISTRATION).
The side effectmostfrequentlyreported wasdrowsiness.Lesscommonlyreported (in descending order of occurrence)were:dizziness, various gastrointestinal complaints,nervousness, blurred vision, dry mouth,headache, and mentalconfusion.Other side effects included insomnia,transientskinrashes,fatigue,ataxia,genitourinarycomplaints,irritability,diplopia,depression,tremor, and slurredspeech.
There have been reports of abnormalliver and kidneyfunction tests and of decrease in hematocrit.
Decrease in systolicbloodpressurehas been observed.

Clorazepate dipotassium tablets contains clorazepate, a ScheduleIV controlled substance.
Clorazepate dipotassium tablets is 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 of benzodiazepines 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: Abuse, Misuse, and Addiction).
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).
Physical Dependence
Clorazepate dipotassium tablets 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: Dependence and Withdrawal Reactions).
To reduce the risk of withdrawal reactions, use a gradual taper to discontinue Clorazepate dipotassium tablets or reduce the dosage (see DOSAGE and ADMINISTRATION: Discontinuation or Dosage Reduction of Clorazepate dipotassium tablets and WARNINGS: Dependence and Withdrawal Reactions).
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 to Clorazepate dipotassium tablets may develop from continued therapy.Tolerance is a physiologicalstatecharacterized by a reducedresponse to a drugafterrepeatedadministration(i.e., a higher dose of a drug is required to produce the sameeffect that was once obtained at a lower dose). Tolerance to the therapeuticeffect of Clorazepate dipotassium tablets may develop; however,littletolerancedevelops to the amnesticreactionsand other cognitiveimpairments caused bybenzodiazepines.
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: Dependence and Withdrawal Reactions). 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 (1-800-222-1222) or a medical toxicologist for additional overdosage management recommendations.
FortheSymptomatic ReliefofAnxiety:Clorazepate dipotassium tablets are administeredorally in divided doses. The usual daily dose is 30mg.The dose should beadjustedgraduallywithintherange of 15 to 60 mg daily in accordancewith the response of the patient. In elderly or debilitatedpatientsit is advisable to initiate treatment at a daily dose of 7.5 to 15 mg.
Clorazepate dipotassium tabletsmay also be administeredin a singledosedaily at bedtime; the recommendedinitialdose is 15 mg.After the initial dose, the response of the patient mayrequireadjustment of subsequent dosage.Lower doses may be indicated in the elderlypatient. Drowsinessmay occur at the initiation of treatment and withdosageincrement.
For the Symptomatic Relief of Acute Alcohol Withdrawal:
Thefollowing dosage scheduleisrecommended:
| 1st 24 hours (Day 1) | 30 mginitially;followed by 30 to 60 mg in divideddoses |
| 2nd 24 hours (Day 2) | 45 to 90 mg in divideddoses |
| 3rd 24 hours (Day 3) | 22.5 to 45 mg in divided doses |
| Day 4 | 15 to 30 mg in divideddoses |
Thereafter,graduallyreduce the daily dose to 7.5 to 15 mg.Discontinuedrugtherapy as soon as patient’s condition is stable.
Themaximum recommendedtotaldailydose is 90 mg. Avoid excessive reductionsin the totalamount of drug administeredonsuccessive days.
As an Adjunct to Antiepileptic Drugs: In order to minimizedrowsiness, the recommendedinitialdosages and dosageincrementsshould not be exceeded.
Adults: Themaximum recommendedinitialdose in patients over 12 years old is 7.5 mg three times a day. Dosage should be increased by no more than 7.5mg every week and should not exceed 90 mg/day.
Children (9-12 years): Themaximum recommendedinitial dose is 7.5 mgtwotimes a day. Dosage should be increased by no more than 7.5mg every week and should not exceed 60 mg/day.
Discontinuation or DosageReduction of Clorazepate dipotassium tablets: To reduce the risk of withdrawalreactions,use a gradualtaper to discontinueClorazepate dipotassium tablets or reduce the dosage. If a patient develops withdrawalreactions,consider pausing the taper or increasingthe dosage to the previous tapereddosage level. Subsequentlydecreasethedosagemoreslowly (see WARNINGS and DRUG ABUSE AND DEPENDENCE).
Studies in rats and monkeys have shown a substantial difference between doses producing tranquilizing, sedative and toxic effects. In rats, conditioned avoidance response was inhibited at an oral dose of 10 mg/kg; sedation was induced at 32 mg/kg; the LD50 was 1320 mg/kg. In monkeys aggressive behavior was reduced at an oral dose of 0.25 mg/kg; sedation (ataxia) was induced at 7.5 mg/kg; the LD50 could not be determined because of the emetic effect of large doses, but the LD50 exceeds 1600 mg/kg.
Twenty-four dogs were given clorazepate dipotassium orally in a 22-month toxicity study; doses up to 75 mg/kg were given. Drug-related changes occurred in the liver; weight was increased and cholestasis with minimal hepatocellular damage was found, but lobular architecture remained well preserved.
Eighteen rhesus monkeys were given oral doses of clorazepate dipotassium from 3 to 36 mg/kg daily for 52 weeks. All treated animals remained similar to control animals.
Although total leucocyte count remained within normal limits it tended to fall in the female animals on the highest doses.
Examination of all organs revealed no alterations attributable to clorazepate dipotassium. There was no damage to liver function or structure.
Reproduction Studies: In fertility studies, clorazepate did not alter the fertility indices or reproductive capacity of adult animals (see Pregnancy).
