✅ Uses & Indications
1 INDICATIONS AND USAGE XANAX is indicated for the: • acute treatment of generalized anxiety disorder (GAD) in adults. • treatment of panic disorder (PD), with or without agoraphobia in adults. XANAX is a benzodiazepine indicated for the: • Acute treatment of generalized anxiety disorder in adults. ( 1 ) • Treatment of panic disorder with or without agoraphobia in adults. ( 1 )
📏 Dosage & Administration
2 DOSAGE AND ADMINISTRATION • Generalized Anxiety Disorder : ( 2.1 ) o Recommended starting oral dosage is 0.25 mg to 0.5 mg three times daily. o Dosage may be increased, at intervals of every 3 to 4 days, to a maximum recommended daily dose of 4 mg, given in divided doses. o Use the lowest possible effective dose and frequently assess the need for continued treatment. • Panic Disorder : Recommended starting oral dosage is 0.5 mg three times daily. The dosage may be increased at intervals of every 3 to 4 days in increments of no more than 1 mg per day. ( 2.2 ) • When tapering, decrease dosage by no more than 0.5 mg every 3 days. Some patients may require an even slower dosage reduction. ( 2.3 , 5.2 ) • See the Full Prescribing Information for the recommended dosage in geriatric patients, patients with hepatic impairment, and with use with ritonavir. ( 2.4 , 2.5 , 2.6 ) 2.1 Dosage in Generalized Anxiety Disorder The recommended starting oral dosage of XANAX for the acute treatment of patients with GAD is 0.25 mg to 0.5 mg administered three times daily. Depending upon the response, the dosage may be adjusted at intervals of every 3 to 4 days. The maximum recommended dosage is 4 mg daily (in divided doses). Use the lowest possible effective dose and frequently assess the need for continued treatment [see Warnings and Precautions (5.2) ] . 2.2 Dosage in Panic Disorder The recommended starting oral dosage of XANAX for the treatment of PD is 0.5 mg three times daily. Depending on the response, the dosage may be increased at intervals of every 3 to 4 days in increments of no more than 1 mg per day. Controlled trials of XANAX in the treatment of panic disorder included dosages in the range of 1 mg to 10 mg daily. The mean dosage was approximately 5 mg to 6 mg daily. Occasional patients required as much as 10 mg per day. For patients receiving doses greater than 4 mg per day, periodic reassessment and consideration of dosage reduction is advised. In a controlled postmarketing dose-response study, patients treated with doses of XANAX greater than 4 mg per day for 3 months were able to taper to 50% of their total maintenance dose without apparent loss of clinical benefit. The necessary duration of treatment for PD in patients responding to XANAX is unknown. After a period of extended freedom from panic attacks, a carefully supervised tapered discontinuation may be attempted, but there is evidence that this may often be difficult to accomplish without recurrence of symptoms and/or the manifestation of withdrawal phenomena [see Dosage and Administration (2.3) ] . 2.3 Discontinuation or Dosage Reduction of XANAX To reduce the risk of withdrawal reactions, use a gradual taper to discontinue XANAX 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) , Drug Abuse and Dependence (9.3) ] . Reduced the dosage by no more than 0.5 mg every 3 days. Some patients may benefit from an even more gradual discontinuation. Some patients may prove resistant to all discontinuation regimens. In a controlled postmarketing discontinuation study of panic disorder patients which compared the recommended taper schedule with a slower taper schedule, no difference was observed between the groups in the proportion of patients who tapered to zero dose; however, the slower schedule was associated with a reduction in symptoms associated with a withdrawal syndrome. 2.4 Dosage Recommendations in Geriatric Patients In geriatric patients, the recommended starting oral dosage of XANAX is 0.25 mg, given 2 or 3 times daily. This may be gradually increased if needed and tolerated. Geriatric patients may be especially sensitive to the effects of benzodiazepines. If adverse reactions occur at the recommended starting dosage, the dosage may be reduced [see Use in Specific Populations (8.5) , Clinical Pharmacology (12.3) ] . 2.5 Dosage Recommendations in Patients with Hepatic Impairment In patients with hepatic impairment, the recommended starting oral dosage of XANAX is 0.25 mg, given 2 or 3 times daily. This may be gradually increased if needed and tolerated. If adverse reactions occur at the recommended starting dose, the dosage may be reduced [see Use in Specific Populations (8.6) , Clinical Pharmacology (12.3) ] . 2.6 Dosage Modifications for Drug Interactions XANAX should be reduced to half of the recommended dosage when a patient is started on ritonavir and XANAX together, or when ritonavir administered to a patient treated with XANAX. Increase the XANAX dosage to the target dose after 10 to 14 days of dosing ritonavir and XANAX together. It is not necessary to reduce XANAX dose in patients who have been taking ritonavir for more than 10 to 14 days. XANAX is contraindicated with concomitant use of all strong CYP3A inhibitors, except ritonavir [see Contraindications (4) , Warnings and Precautions (5.5) ] .

Adverse Reactions Reported as Reasons for Discontinuation in Treatment of Panic Disorder in Placebo-Controlled Trials In a larger database comprised of both controlled and uncontrolled studies in which 641 patients received XANAX, discontinuation-emergent symptoms which occurred at a rate of over 5% in patients treated with XANAX and at a greater rate than the placebo-treated group are shown in Table 3. Table 3: Discontinuation-Emergent Symptom Incidence Reported in ≥5% of XANAX-treated Patients and > Placebo-treated Patients n=number of patients. XANAX-treated Patients n=641 Nervous system disorders Insomnia 29.5% Light-headedness 19.3% Abnormal involuntary movement 17.3% Headache 17.0% Muscular twitching 6.9% Impaired coordination 6.6% Muscle tone disorders 5.9% Weakness 5.8% Psychiatric disorders Anxiety 19.2% Fatigue and Tiredness 18.4% Irritability 10.5% Cognitive disorder 10.3% Memory impairment 5.5% Depression 5.1% Confusional state 5.0% Gastrointestinal disorders Nausea/Vomiting 16.5% Diarrhea 13.6% Decreased salivation 10.6% Metabolism and nutrition disorders Weight loss 13.3% Decreased appetite 12.8% Dermatological disorders Sweating 14.4% Cardiovascular disorders Tachycardia 12.2% Special Senses Blurred vision 10.0% There have also been reports of withdrawal seizures upon rapid decrease or abrupt discontinuation of XANAX [see Warning and Precautions (5.2) and Drug Abuse and Dependence (9.3) ] . Paradoxical reactions such as stimulation, increased muscle spasticity, sleep disturbances, hallucinations, and other adverse behavioral effects such as agitation, rage, irritability, and aggressive or hostile behavior have been reported rarely. In many of the spontaneous case reports of adverse behavioral effects, patients were receiving other CNS drugs concomitantly and/or were described as having underlying psychiatric conditions. Should any of the above events occur, alprazolam should be discontinued. Isolated published reports involving small numbers of patients have suggested that patients who have borderline personality disorder, a prior history of violent or aggressive behavior, or alcohol or substance abuse may be at risk for such events. Instances of irritability, hostility, and intrusive thoughts have been reported during discontinuation of alprazolam in patients with posttraumatic stress disorder. 6.2 Postmarketing Experience The following adverse reactions have been identified during postapproval use of XANAX. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Endocrine disorders: Hyperprolactinemia General disorders and administration site conditions: Edema peripheral Hepatobiliary disorders: Hepatitis, hepatic failure Investigations: Liver enzyme elevations Psychiatric disorders: Hypomania, mania Reproductive system and breast disorders: Gynecomastia, galactorrhea Skin and subcutaneous tissue disorders: Photosensitivity reaction, angioedema, Stevens-Johnson syndrome
⚠️ Warnings & Precautions
5 WARNINGS AND PRECAUTIONS • Effects on Driving and Operating Machinery: Patients receiving XANAX should be cautioned against operating machinery or driving a motor vehicle, as well as avoiding concomitant use of alcohol and other central nervous system (CNS) depressant drugs. ( 5.4 ) • Patients with Depression: Exercise caution in patients with signs or symptoms of depression. Prescribe the least number of tablets feasible to avoid intentional overdosage. ( 5.6 ) • Neonatal Sedation and Withdrawal Syndrome: XANAX use during pregnancy can result in neonatal sedation and/or neonatal withdrawal. ( 5.8 , 8.1 ) 5.1 Risks from Concomitant Use with Opioids Concomitant use of benzodiazepines, including XANAX, 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 XANAX 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 XANAX than indicated in the absence of an opioid and titrate based on clinical response. If an opioid is initiated in a patient already taking XANAX, 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 XANAX 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 Drug Interactions (7.1) ] . 5.2 Abuse, Misuse, and Addiction The use of benzodiazepines, including XANAX, 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 (9.2) ] . Before prescribing XANAX and throughout treatment, assess each patient’s risk for abuse, misuse, and addiction (e.g., using a standardized screening tool). Use of XANAX, particularly in patients at elevated risk, necessitates counseling about the risks and proper use of XANAX 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. 5.3 Dependence and Withdrawal Reactions To reduce the risk of withdrawal reactions, use a gradual taper to discontinue XANAX or reduce the dosage (a patient-specific plan should be used to taper the dose) [see Dosage and Administration (2.3) ] . 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 XANAX, may lead to clinically significant physical dependence. Abrupt discontinuation or rapid dosage reduction of XANAX 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 (9.3) ] . 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 (9.3) ] . Certain adverse clinical events, some life-threatening, are a direct consequence of physical dependence to XANAX. These include a spectrum of withdrawal symptoms; the most important is seizure [see Drug Abuse and Dependence (9.3)] . Even after relatively short-term use at doses of ≤4 mg/day, there is some risk of dependence. Spontaneous reporting system data suggest that the risk of dependence and its severity appear to be greater in patients treated with doses greater than 4 mg/day and for long periods (more than 12 weeks). However, in a controlled postmarketing discontinuation study of panic disorder patients who received XANAX, the duration of treatment (3 months compared to 6 months) had no effect on the ability of patients to taper to zero dose. In contrast, patients treated with doses of XANAX greater than 4 mg/day had more difficulty tapering to zero dose than those treated with less than 4 mg/day. In a controlled clinical trial in which 63 patients were randomized to XANAX and where withdrawal symptoms were specifically sought, the following were identified as symptoms of withdrawal: heightened sensory perception, impaired concentration, dysosmia, clouded sensorium, paresthesias, muscle cramps, muscle twitch, diarrhea, blurred vision, appetite decrease, and weight loss. Other symptoms, such as anxiety and insomnia, were frequently seen during discontinuation, but it could not be determined if they were due to return of illness, rebound, or withdrawal. Interdose Symptoms Early morning anxiety and emergence of anxiety symptoms between doses of XANAX have been reported in patients with panic disorder taking prescribed maintenance doses. These symptoms may reflect the development of tolerance or a time interval between doses which is longer than the duration of clinical action of the administered dose. In either case, it is presumed that the prescribed dose is not sufficient to maintain plasma levels above those needed to prevent relapse, rebound, or withdrawal symptoms over the entire course of the interdosing interval. 5.4 Effects on Driving and Operating Machinery Because of its CNS depressant effects, patients receiving XANAX should be cautioned against engaging in hazardous occupations or activities requiring complete mental alertness such as operating machinery or driving a motor vehicle. For the same reason, patients should be cautioned about the concomitant use of alcohol and other CNS depressant drugs during treatment with XANAX [see Drug Interactions (7.1) ] . 5.5 Interaction with Drugs that Inhibit Metabolism via Cytochrome P450 3A The initial step in alprazolam metabolism is hydroxylation catalyzed by cytochrome P450 3A (CYP3A). Drugs that inhibit this metabolic pathway may have a profound effect on the clearance of alprazolam. Strong CYP3A Inhibitors XANAX is contraindicated in patients receiving strong inhibitors of CYP3A (such as azole antifungal agents), except ritonavir [see Contraindications (4) ] . Ketoconazole and itraconazole have been shown in vivo to increase plasma alprazolam concentrations 3.98 fold and 2.70 fold, respectively. Dosage adjustment is necessary when XANAX and ritonavir are initiated concomitantly or when ritonavir is added to a stable dosage of XANAX [see Dosage and Administration (2.6) , Drug Interactions (7.1) ] . Drugs demonstrated to be CYP3A inhibitors on the basis of clinical studies involving alprazolam: nefazodone, fluvoxamine, and cimetidine [see Drug Interaction (7.1) , Clinical Pharmacology (12.3) ] . Use caution and consider dose reduction of XANAX, as appropriate, during co-administration with these drugs. 5.6 Patients with Depression Benzodiazepines may worsen depression. Panic disorder has been associated with primary and secondary major depressive disorders and increased reports of suicide among untreated patients. Consequently, appropriate precautions (e.g., limiting the total prescription size and increased monitoring for suicidal ideation) should be considered in patients with depression. 5.7 Mania Episodes of hypomania and mania have been reported in association with the use of XANAX in patients with depression [see Adverse Reactions (6.2) ] . 5.8 Neonatal Sedation and Withdrawal Syndrome Use of XANAX 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 Use in Specific Populations (8.1) ] . Monitor neonates exposed to XANAX during pregnancy or labor for signs of sedation and monitor neonates exposed to XANAX during pregnancy for signs of withdrawal; manage these neonates accordingly. 5.9 Risk in Patients with Impaired Respiratory Function There have been reports of death in patients with severe pulmonary disease shortly after the initiation of treatment with XANAX. Closely monitor patients with impaired respiratory function. If signs and symptoms of respiratory depression, hypoventilation, or apnea occur, discontinue XANAX.
🔄 Drug Interactions
7 DRUG INTERACTIONS • Use with Opioids: Increase the risk of respiratory depression. ( 7.1 ) • Use with Other CNS Depressants: Produces additive CNS depressant effects. ( 7.1 ) • Use with Digoxin: Increase the risk of digoxin toxicity. ( 7.1 ) • Use with CYP3A Inhibitors (except ritonavir): Increase the risk of adverse reactions of alprazolam. ( 4 , 5.5 , 7.1 ) • Use with CYP3A Inducers: Increase the risk of reduced efficacy of alprazolam. ( 7.1 ) 7.1 Drugs Having Clinically Important Interactions with XANAX Table 4 includes clinically significant drug interactions with XANAX [see Clinical Pharmacology (12.3) ] . Table 4: Clinically Significant Drug Interactions with XANAX Opioids Clinical implication 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 gamma-aminobutyric acid (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. Prevention or management Limit dosage and duration of concomitant use of XANAX and opioids, and monitor patients closely for respiratory depression and sedation [see Warnings and Precautions (5.1) ] . Examples Morphine, buprenorphine, hydromorphone, oxymorphone, oxycodone, fentanyl, methadone, alfentanil, butorphanol, codeine, dihydrocodeine, meperidine, pentazocine, remifentanil, sufentanil, tapentadol, tramadol. CNS Depressants Clinical implication The benzodiazepines, including alprazolam, produce additive CNS depressant effects when coadministered with other CNS depressants. Prevention or management Limit dosage and duration of XANAX during concomitant use with CNS depressants [see Warnings and Precautions (5.3) ] . Examples Psychotropic medications, anticonvulsants, antihistaminics, ethanol, and other drugs which themselves produce CNS depression. Strong Inhibitors of CYP3A (except ritonavir) Clinical implication Concomitant use of XANAX with strong CYP3A inhibitors has a profound effect on the clearance of alprazolam, resulting in increased concentrations of alprazolam and increased risk of adverse reactions [see Clinical Pharmacology (12.3) ]. Prevention or management Concomitant use of XANAX with a strong CYP3A4 inhibitor (except ritonavir) is contraindicated [see Contraindications (4) , Warnings and Precautions (5.5) ]. Examples Ketoconazole, itraconazole, clarithromycin Moderate or Weak Inhibitors of CYP3A Clinical implication Concomitant use of XANAX with CYP3A inhibitors may increase the concentrations of XANAX, resulting in increased risk of adverse reactions of alprazolam [see Clinical Pharmacology (12.3) ]. Prevention or management Avoid use and consider appropriate dose reduction when XANAX is coadministered with a moderate or weak CYP3A inhibitor [see Warnings and Precautions (5.5) ]. Examples Nefazodone, fluvoxamine, cimetidine, erythromycin CYP3A Inducers Clinical implication Concomitant use of CYP3A inducers can increase alprazolam metabolism and therefore can decease plasma levels of alprazolam [see Clinical Pharmacology (12.3) ] . Prevention or management Caution is recommended during coadministration with XANAX. Examples Carbamazepine, phenytoin Ritonavir Clinical implication Interactions involving ritonavir and alprazolam are complex and time dependent. Short term administration of ritonavir increased alprazolam exposure due to CYP3A4 inhibition. Following long term treatment of ritonavir (>10 to 14 days), CYP3A4 induction offsets this inhibition. Alprazolam exposure was not meaningfully affected in the presence of ritonavir. Prevention or management Reduce XANAX dosage when ritonavir and XANAX are initiated concomitantly, or when ritonavir is added to a regimen where XANAX is stabilized. Increase XANAX dosage to the target dosage after 10 to 14 days of dosing ritonavir and XANAX concomitantly. No dosage adjustment of XANAX is necessary in patients receiving ritonavir for more than 10 to14 days [see Dosage and Administration (2.6) ] . Concomitant use of XANAX with a strong CYP3A inhibitor, except ritonavir, is contraindicated [see Contraindications (4) , Warnings and Precautions (5.5) ]. Digoxin Clinical implication Increased digoxin concentrations have been reported when alprazolam was given, especially in geriatric patients (>65 years of age). Prevention or management In patients on digoxin therapy, measure serum digoxin concentrations before initiating XANAX. Continue monitoring digoxin serum concentration and toxicity frequently . Reduce the digoxin dose if necessary. 7.2 Drug/Laboratory Test Interactions Although interactions between benzodiazepines and commonly employed clinical laboratory tests have occasionally been reported, there is no consistent pattern for a specific drug or specific test.
