🚨 Boxed Warning ▾
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 for 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) , Drug Interactions (7.1) ] . The use of benzodiazepines, including alprazolam extended-release tablets , 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 alprazolam extended-release tablets 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 alprazolam extended-release tablets , 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 alprazolam extended-release tablets 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 alprazolam extended-release tablets or reduce the dosage [see Dosage and Administration (2.2) , Warnings and Precautions (5.3) ] . WARNING: RISKS FROM CONCOMITANT USE WITH OPIOIDS; ABUSE, MISUSE, AND ADDICTION; and DEPENDENCE AND WITHDRAWAL REACTIONS See full prescribing information for complete boxed warning.

🎯 Indications and Usage ▾
1 INDICATIONS AND USAGE Alprazolam extended-release tablets are indicated for the treatment of panic disorder with or without agoraphobia, in adults. Alprazolam extended-release tablets are a benzodiazepine indicated for the treatment of panic disorder with or without agoraphobia, in adults. ( 1 )
⏱️ Dosage and Administration ▾
2 DOSAGE AND ADMINISTRATION Recommended starting oral dosage is 0.5 mg to 1 mg once daily (preferably in the morning). Depending on the response, the dose may be increased at intervals of 3 to 4 days in increments of no more than 1 mg daily. ( 2.1 ) Recommended total daily dosage is 3 mg to 6 mg daily.
( 2.1 ) Swallow tablets whole; do not divide, crush, or chew. ( 2.1 ) When tapering, decrease dosage by no more than 0.5 mg every 3 days. Some patients may require an even slower dosage reduction.
( 2.2 , 5.2 ) See the Full Prescribing Information for the recommended dosage in geriatric patients, patients with hepatic impairment, and with use with ritonavir. ( 2.3 , 2.4 , 2.5 )
2.1Recommended Dosage Administer alprazolam extended-release tablets orally once daily, preferably in the morning. Swallow tablets whole; do not divide, crush, or chew. The recommended starting oral dosage for alprazolam extended-release tablets is 0.5 mg to 1 mg once daily.
Depending on the response, the dosage may be adjusted at intervals of every 3 to 4 days in increments of no more than 1 mg daily. The recommended dosage range is 3 mg to 6 mg once daily. Controlled trials of alprazolam extended-release tablets for the treatment of panic disorder included dosages in the range of 1 mg to 10 mg per day.
Most patients showed a response in the dosage range of 3 mg to 6 mg per day. Occasional patients required as much as 10 mg per day. The longer-term efficacy of alprazolam extended-release tablets has not been systematically evaluated.
If alprazolam extended-release tablets are used for periods longer than 8 weeks, the healthcare provider should periodically reassess the usefulness of the drug for the individual patient. 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 (2.2) , Warnings and Precautions (5.2) ] .
2.2Discontinuation or Dosage Reduction of Alprazolam Extended-Release Tablets To reduce the risk of withdrawal reactions, use a gradual taper to discontinue alprazolam extended-release tablets 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) ].
Reduce the dosage by no more than 0.5 mg every three days. Some patients may benefit from an even more gradual discontinuation. Some patients may prove resistant to all discontinuation regimens.
In a controlled post-marketing 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.
2.3Dosage Recommendations in Geriatric Patients In geriatric patients, the recommended starting dosage of alprazolam extended-release tablets is 0.5 mg once daily. This may be gradually increased if needed and tolerated . Geriatric patients may be sensitive to the effects of benzodiazepines [see Use in Specific Populations (8.5) , Clinical Pharmacology (12.3) ] .
2.4Dosage Recommendations in Patients with Hepatic Impairment In patients with hepatic impairment, the recommended starting dosage of alprazolam extended-release tablets is 0.5 mg once daily. This may be gradually increased if needed and tolerated [see Use in Specific Populations (8.6) , Clinical Pharmacology (12.3) ].
2.5Dosage Modifications for Drug Interactions Alprazolam extended-release tablets should be reduced to half of the recommended dosage when a patient is started on ritonavir and alprazolam extended-release tablets…

Angioedema has been reported [see Adverse Reactions (6.2) ]. taking strong cytochrome P450 3A (CYP3A) inhibitors (e.g., ketoconazole, itraconazole), except ritonavir [see Dosage and Administration (2.5) , Warnings and Precautions (5.5) , Drug Interactions (7.1) ] . Known hypersensitivity to alprazolam or other benzodiazepines.
( 4 ) Concomitant use with strong cytochrome P450 3A (CYP3A) inhibitors, except ritonavir. ( 4 , 5.5 , 7.1 )
⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS Effects on Driving and Operating Machinery: Patients receiving alprazolam extended-release tablets 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: Alprazolam extended-release tablets use during pregnancy can result in neonatal sedation and/or neonatal withdrawal. ( 5.8 , 8.1 )
5.1Risks from Concomitant Use with Opioids Concomitant use of benzodiazepines, including alprazolam extended-release 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 alprazolam extended-release 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 alprazolam extended-release 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 alprazolam extended-release 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 alprazolam extended-release 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 Drug Interactions (7.1) ].
5.2Abuse, Misuse, and Addiction The use of benzodiazepines, including alprazolam extended-release 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 (9.2) ] .
Before prescribing alprazolam extended-release tablets and throughout treatment, assess each patient’s risk for abuse, misuse, and addiction (e.g., using a standardized screening tool). Use of alprazolam extended-release tablets, particularly in patients at elevated risk, necessitates counseling about the risks and proper use of alprazolam extended-release 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.
5.3Dependence and Withdrawal Reactions To reduce the risk of withdrawal reactions, use a gradual taper to discontinue alprazolam extended-release tablets 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…

6.1Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The information included in the section on Adverse Reactions Observed in Short-Term, Placebo-Controlled Trials with alprazolam extended-release tablets is based on pooled data of five 6- and 8-week placebo-controlled clinical studies in panic disorder.
Adverse Reactions Observed in Short-Term, Placebo-Controlled Trials of Alprazolam Extended-Release Tablets Adverse Reactions Reported as Reasons for Discontinuation of Treatment in Placebo-Controlled Trials Approximately 17% of the 531 patients who received alprazolam extended-release tablets in placebo-controlled clinical trials for panic disorder had at least 1 adverse event that led to discontinuation compared to 8% of 349 placebo-treated patients. The most common events leading to discontinuation and considered to be drug-related (i.e., leading to discontinuation in at least 1% of the patients treated with alprazolam extended-release tablets at a rate at least twice that of placebo) are shown in Table 1.

7.1Drugs Having Clinically Important Interactions with Alprazolam Extended-Release Tablets Table 4 includes clinically significant drug interactions with alprazolam extended-release tablets [see Clinical Pharmacology (12.3) ] . Table 4: Clinically Significant Drug Interactions with Alprazolam Extended-Release Tablets 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 (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. Prevention or management Limit dosage and duration of concomitant use of alprazolam extended-release tablets 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, butorpenol, codeine, dihydrocodeine, meperidine, pentazocine, remifentanil, sufentanil, tapentadol, tramadol. CNS Depressants Clinical implication The benzodiazepines, including alprazolam, produce additive CNS depressant effects when co-administered with other CNS depressants. Prevention or management Limit dosage and duration of alprazolam extended-release tablets 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 alprazolam extended-release tablets 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 alprazolam extended-release tablets 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 alprazolam extended-release tablets with CYP3A inhibitors may increase the concentrations of alprazolam extended-release tablets, resulting in increased risk of adverse reactions [see Clinical Pharmacology (12.3) ]. Prevention or management Avoid use and consider appropriate dose reduction when alprazolam extended-release tablets is co-administered 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 co-administration with alprazolam. 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 - 14 days), CYP3A4 induction offsets this inhibition. Alprazolam exposure was not meaningfully affec…
👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS Lactation: Breastfeeding not recommended. ( 8.2 )
8.1Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to psychiatric medications, including alprazolam extended-release tablets 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 (5.8) , 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 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 alprazolam extended-release tablets during pregnancy or labor for signs of sedation, respiratory depression, hypotonia, and feeding problems.
Monitor neonates exposed to alprazolam extended-release tablets during pregnancy for signs of withdrawal. Manage these neonates accordingly [see Warnings and Precautions (5.8) ]. 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 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.
8.2Lactation Risk Summary Limited data from published literature reports the presence of alprazolam in human breast milk. There are reports of sedation, poor feeding and poor weight gain in infants exposed to benzodiazepines through breast milk. The effects of alprazolam on lactation are unknown.
Because of the potential for serious adverse reactions, including sedation and withdrawal symptoms in breastfed infants, advise patients that breastfeeding is not recommended during treatment with alprazolam extended-release tablets.
8.4Pediatric Use Safety and effectiveness of alprazolam extended-release tablets have not been established in pediatric patients.
8.5Geriatric Use Alprazolam extended-release tablets-treated geriatric patients had higher plasma concentrations of alprazolam (due to reduced clearance) compared to younger adults receiving the same doses. Therefore, dosage reduction of alprazolam extended-release tablets is recommended in geriatric patients [see Dosage and Administration (2.3) and Clinical Pharmacology (12.3) ] .
8.6Hepatic Impairment Patients with alcoholic liver disease exhibit a longer elimination half-life (19.7 hours), compared to healthy subjects (11.4 hours). This may be caused by decreased clearance of alprazolam extended-release tablets in patients with alcoholic liver disease. Dosage reduction of alprazolam is recommended in patients with hepatic impairment [see Dosage and Administration (2.4) , Clinical Pharmacology (12.3) ] .

Therefore, dosage reduction of alprazolam extended-release tablets is recommended in geriatric patients [see Dosage and Administration (2.3) and Clinical Pharmacology (12.3) ] .
🆘 Overdosage ▾
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 the Poison Help Line at (1-800-222-1222), or a medical toxicologist for additional overdosage management recommendations.

12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Alprazolam is a 1,4 benzodiazepine. Alprazolam exerts its effect for the treatment of panic disorder through binding to the benzodiazepine site of gamma-aminobutyric acid-A (GABA A ) receptors in the brain and enhances GABA-mediated synaptic inhibition.
12.3Pharmacokinetics The pharmacokinetics of alprazolam and two of its major active metabolites (4-hydroxyalprazolam and α-hydroxyalprazolam) are linear, and concentrations are proportional up to 10 mg alprazolam extended-release tablets given once daily. Absorption Following oral administration of alprazolam extended-release tablets in the morning, peak plasma concentration of alprazolam (C max ) occurs in about 10 hours postdose. Compared to morning dosing, alprazolam C max increased by 30% and the T max decreased by an hour following dosing at night.
The mean absolute bioavailability of alprazolam following administration of alprazolam extended-release tablet is approximately 90%, and the relative bioavailability compared to alprazolam immediate-release tablet is about 100%. The bioavailability and pharmacokinetics of alprazolam following administration of alprazolam extended-release tablets are similar to that for alprazolam immediate-release tablets, with the exception of a slower rate of absorption. Effect of Food A high-fat meal given up to 2 hours before dosing with alprazolam extended-release tablets increased the mean C max by about 25%.
The effect of this meal on T max depended on the timing of the meal, with a reduction in T max by about 1/3 for subjects eating immediately before dosing and an increase in T max by about 1/3 for subjects eating 1 hour or more after dosing. The extent of exposure (AUC) and elimination half-life (t ½ ) were not affected by eating. Distribution The apparent volume of distribution of alprazolam is similar for alprazolam extended-release tablets and alprazolam immediate-release tablets.
Alprazolam is 80% bound to human serum protein, and albumin accounts for the majority of the binding. Elimination The mean plasma elimination half-life of alprazolam following administration of alprazolam extended-release tablets ranges from 10.7 to 15.8 hours in healthy adults. Metabolism Alprazolam is extensively metabolized in humans, primarily by cytochrome P450 3A4 (CYP3A4), to two major active metabolites in the plasma: 4-hydroxyalprazolam and α-hydroxyalprazolam.
The plasma circulation levels of the two active metabolites after both alprazolam extended-release tablets and alprazolam immediate-release tablets are less than 10% and 4% of the parent, respectively. The reported relative potencies in benzodiazepine receptor binding experiments and in animal models of induced seizure inhibition are 0.20 and 0.66, respectively, for 4-hydroxyalprazolam and α-hydroxyalprazolam. The low concentrations and low potencies of 4-hydroxyalprazolam and α-hydroxyalprazolam indicate that they unlikely contribute much to the effects of alprazolam.
A benzophenone derived from alprazolam is also found in humans. Their half-lives appear to be similar to that of alprazolam. The pharmacokinetic parameters at steady-state for the two hydroxylated metabolites of alprazolam (4-hydroxyalprazolam and α-hydroxyalprazolam) were similar for alprazolam immediate-release tablets and alprazolam extended-release tablets, indicating that the metabolism of alprazolam is not affected by absorption rate.
Excretion Alprazolam and its metabolites are excreted primarily in the urine. Specific Populations Geriatric Patients The mean T 1/2 of alprazolam was 16.3 hours (range: 9.0 to 26.9 hours) in healthy elderly subjects compared to 11.0 hours (range: 6.3 to 15.8 hours, n=16) in healthy adult subjects. Obese Patients The mean T 1/2 of alprazolam was 21.8 hours (range: 9.9 to 40.4 hours) in a group of obese subjects.
Patients with Hepatic Impairment The mean T 1/2 of alprazolam was 19.7 hours (range: 5.8 to 65.3 hours) in patients with alcoholi…

💬 Information for Patients ▾
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 alprazolam is used with opioids and not to use such drugs concomitantly unless supervised by a healthcare provider. Advise patients not to drive or operate heavy machinery until the effects of concomitant use with the opioid have been determined [see Warnings and Precautions (5.1) , Drug Interactions (7.1) ].
Abuse, Misuse, and Addiction Inform patients that the use of alprazolam, 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) , Drug Abuse and Dependence (9.2) ] .
Withdrawal Reactions Inform patients that the continued use of alprazolam may lead to clinically significant physical dependence and that abrupt discontinuation or rapid dosage reduction of alprazolam 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 alprazolam may require a slow taper [see Warnings and Precautions (5.3) , Drug Abuse and Dependence (9.3) ] .
Effects on Driving and Operating Machinery Advise patients not to drive a motor vehicle or operate heavy machinery while taking alprazolam due to its CNS depressant effects. Also advise patients to avoid use of alcohol or other CNS depressants while taking alprazolam [see Warnings and Precautions (5.3) ] . Patients with Depression Advise patients, their families and caregivers to look for signs of suicidality or worsening depression, and to inform the patient’s healthcare provider immediately [see Warnings and Precautions (5.6 ) ] .
Concomitant Medications Advise patients to inform their healthcare provider of all medicines they take, including prescription and nonprescription medications, vitamins and herbal supplements [see Drug Interactions (7) ] . Pregnancy Advise pregnant females that use of alprazolan 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 (5.8) , Use in Specific Populations (8.1) ] .
Instruct patients to inform their healthcare provider if they are pregnant.
