OXAZEPAM

INDICATIONS Oxazepam capsules are indicated for the management of anxiety disorders or for the short-term relief of the symptoms of anxiety. Anxiety or tension associated with the stress of everyday life usually does not require treatment with an anxiolytic. Anxiety associated with depression is also responsive to oxazepam therapy. This product has been found particularly useful in the management of anxiety, tension, agitation and irritability in older patients. Alcoholics with acute tremulousness, inebriation, or with anxiety associated with alcohol withdrawal are responsive to therapy. The effectiveness of oxazepam in long-term use, that is, more than 4 months, has not been assessed by systematic clinical studies. The physician should periodically reassess the usefulness of the drug for the individual patient.

DOSAGE AND ADMINISTRATION Because of the flexiblllty of this product and the range of emotional disturbances responsive to it, dosage should be individualized for maximum beneflcial effects. Oxazepam Usual Dose Mild-to-moderate anxiety, with associated tension, itritability, agitation, or related symptoms of functional origin or seconday to organic disease. 10 to 15 mg, 3 or 4 times daily Severe anxiety syndromes, agitation, or anxiety associated with depression. 15 to 30 mg, 3 or 4 times daily Older patients with anxiety, tension, irritabillly, and agitation. Initial dosage: 10 mg, 3 times daily. If necessary, increase cautiously to 15 mg, 3 or 4 times daily. Alcoholics with acute inebriation, tremulousness, or anxiety on withdrawal. 15 to 30 mg, 3 or 4 times daily This product is not indicated in pediatric patients under 6 years of age. Absolute dosage tor pediatric patients 6 to 12 years of age is not established. Discontinuation or Dosage Reduction of Oxazepam To reduce the risk of withdrawal reactions, use a gradual taper to discontinue oxazepam 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 oxazepam, 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 oxazepam 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 oxazepam than indicated in the absence of an opioid and titrate based on clinical response. If an opioid is initiated in a patient already taking oxazepam, 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 oxazepam 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 oxazepam, 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 oxazepam and throughout treatment, assess each patient’s risk for abuse, misuse, and addiction (e.g., using a standardized screening tool). Use of oxazepam, particularly in patients at elevated risk, necessitates counseling about the risks and proper use of oxazepam 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 oxazepam or reduce the dosage (a patient-specific plan should be used to taper the dose) [see DOSAGE AND ADMINISTRATION: Discontinuation or Dosage Reduction of Oxazepam ] . 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 oxazepam, may lead to clinically significant physical dependence. Abrupt discontinuation or rapid dosage reduction of oxazepam 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 ] . As with other CNS-acting drugs, patients should be cautioned against driving automobiles or operating dangerous machinery until it is known that they do n…

CONTRAINDICATIONS History of previous hypersensitivity reaction to oxazepam. Oxazepam is not Indicated in psychoses.

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.

Pregnancy 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 PRECAUTIONS: 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 estimated 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 risk of major birth defects and of 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 oxazepam during pregnancy or labor for signs of sedation, respiratory depression, hypotonia, and feeding problems. Monitor neonates exposed to oxazepam 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 Reproductive studies in animals were performed in mice, rats, and two strains of rabbits. Occasional anomalies (reduction of tarsals, tibia, metatarsals, malrotated limbs, gastroschisis, malformed skull, and microphthalmia) were seen in drug-treated rabbits without relationship to dosage. Although all of these anomalies were not present in the concurrent control group, they have been reported to occur randomly in historical controls. At doses of 40 mg/kg and higher, there was evidence of fetal resorption and increased fetal loss in rabbits which was not seen at lower doses.

Nursing Mothers Risk Summary Oxazepam is present in breast milk. There are reports of sedation, poor feeding and poor weight gain in infants exposed to benzodiazepines through breast milk (see Clinical Considerations). The effects of oxazepam on milk production are unknown. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for oxazepam and any potential adverse effects on the breastfed infant from oxazepam or from the underlying maternal condition. Clinical Considerations Infants exposed to oxazepam through breast milk should be monitored for sedation, poor feeding and poor weight gain.

ADVERSE REACTIONS The necessity for discontinuation of therapy due to undesirable effects has been rare. Transient mild drowsiness is commonly seen in the first few days of therapy. If it persists, the dosage should be reduced. In few instances, dizziness, vertigo, headache and rarely syncope have occurred either alone or together with drowsiness. Mild paradoxical reactions: i.e., excitement, stimulation of affect, have been reported in psychiatric patients; these reactions may be secondary to relief of anxiety and usually appear in the first two weeks of therapy. Other side effects occurring during oxazepam therapy include rare instances of minor diffuse skin rashes - morbilliform, urticarial, and maculopapular, nausea, lethargy, edema, slurred speech, tremor, and altered libido. Such side effects have been infrequent and are generally controlled with reduction of dosage. A case of an extensive fixed drug eruption also has been reported. Although rare, leukopenia and hepatic dysfunction including jaundice have been reported during therapy. Periodic blood counts and liver-function tests are advisable. Ataxia with oxazepam has been reported in rare instances and does not appear to be specifically related to dose or age. Although the following side reactions have not as yet been reported with oxazepam, they have occurred with related compounds (chlordiazepoxide and diazepam): paradoxical excitation with severe rage reactions, hallucinations, menstrual irregularities, change in EEG pattern, blood dyscrasias including agranulocytosis, blurred vision, diplopia, incontinence, stupor, disorientation, fever and euphoria. Transient amnesia or memory impairment has been reported in association with the use of benzodiazepines.
