Safety & Warnings
BLACK BOX WARNING
Concomitant use of benzodiazepines, including alprazolam, and opioids may result in profound sedation, respiratory depression, coma, and death. Reserve concomitant prescribing of these drugs for use in patients for whom alternative treatment options are inadequate. Limit dosages and durations to the minimum required. Follow patients for signs and symptoms of respiratory depression and sedation.
The use of benzodiazepines, including alprazolam, exposes users to the risks of abuse, misuse, and addiction, which can lead to overdose or death. Before prescribing alprazolam, assess each patientβs risk of abuse, misuse, and addiction. After alprazolam has been prescribed, assess and monitor each patient regularly for these behaviors and conditions.
The continued use of benzodiazepines, including alprazolam, 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 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 or reduce the dosage.

If you are taking this medication long-term, your doctor may recommend regular blood tests to monitor your condition.
If you regularly consume grapefruit juice or eat grapefruit, discuss this with your doctor, as it may interact with your medication. Similarly, if you start or stop smoking, inform your doctor, as your dosage may need to be adjusted.
If you are 65 years or older, use this medication with caution, as you may be more susceptible to side effects.
This drug can potentially harm an unborn baby if taken during pregnancy. If you become pregnant or are already pregnant while taking this medication, contact your doctor immediately. Taking this medication late in pregnancy may increase the risk of respiratory or feeding problems, low body temperature, or withdrawal symptoms in the newborn. Discuss the potential risks with your doctor.
Overdose Information
Overdose Symptoms:
- Severe drowsiness or somnolence
- Confusion
- Impaired coordination (ataxia)
- Slurred speech
- Hypotension (low blood pressure)
- Bradypnea (slowed breathing)
- Coma
- Death
What to Do:
In case of suspected overdose, seek immediate medical attention. Call 911 or your local poison control center (1-800-222-1222). Flumazenil may be used as an antidote in a hospital setting, but it carries risks, especially in patients with benzodiazepine dependence.
Drug Interactions
Contraindicated Interactions
- Strong CYP3A4 inhibitors (e.g., ketoconazole, itraconazole, clarithromycin, ritonavir, nelfinavir, indinavir) due to significant increase in alprazolam plasma concentrations and prolonged effects.
Major Interactions
- Opioids (e.g., hydrocodone, oxycodone, morphine): Increased risk of profound sedation, respiratory depression, coma, and death. Concomitant use should be avoided unless benefits outweigh risks, and patients should be monitored closely.
- Other CNS depressants (e.g., alcohol, barbiturates, sedating antihistamines, other benzodiazepines, tricyclic antidepressants, antipsychotics): Additive CNS depressant effects, leading to increased sedation, respiratory depression, and psychomotor impairment.
- Moderate CYP3A4 inhibitors (e.g., fluoxetine, fluvoxamine, nefazodone, cimetidine, erythromycin, diltiazem, verapamil): May increase alprazolam plasma concentrations, requiring dose reduction of alprazolam.
Moderate Interactions
- Oral contraceptives: May inhibit alprazolam metabolism, leading to increased alprazolam levels.
- Digoxin: Alprazolam may increase serum digoxin concentrations; monitor digoxin levels.
- Imipramine, desipramine: Alprazolam may increase steady-state plasma concentrations of these antidepressants.
Minor Interactions
- Not available
Monitoring
Baseline Monitoring
Rationale: To establish baseline cognitive function, anxiety/panic symptom severity, and identify any pre-existing psychiatric conditions.
Timing: Prior to initiation of therapy
Rationale: Alprazolam is primarily metabolized by the liver; baseline assessment is important, especially in patients with suspected hepatic impairment.
Timing: Prior to initiation, if clinically indicated
Rationale: Although primarily hepatic, metabolites are renally excreted; baseline assessment is important in patients with suspected renal impairment.
Timing: Prior to initiation, if clinically indicated
Routine Monitoring
Frequency: Regularly, at each visit or as needed
Target: Reduction in symptom severity, improved daily functioning
Action Threshold: Lack of improvement or worsening symptoms may indicate need for dose adjustment or alternative therapy
Frequency: Regularly, at each visit or as needed
Target: Minimal to tolerable side effects
Action Threshold: Excessive sedation, impaired coordination, or significant cognitive dysfunction may require dose reduction or discontinuation
Frequency: Regularly, especially during dose reduction or discontinuation
Target: Absence of withdrawal symptoms (e.g., rebound anxiety, insomnia, seizures)
Action Threshold: Emergence of withdrawal symptoms necessitates slower tapering or re-evaluation of treatment plan
Frequency: Closely, especially during initiation or dose titration of either drug
Target: Normal respiratory rate and depth
Action Threshold: Bradypnea, shallow breathing, or hypoxemia requires immediate medical intervention
Symptom Monitoring
- Excessive drowsiness or sedation
- Dizziness or lightheadedness
- Confusion or disorientation
- Slurred speech
- Difficulty breathing or shallow breathing
- Impaired coordination or ataxia
- Paradoxical reactions (e.g., agitation, aggression, hallucinations)
- Signs of withdrawal upon dose reduction or discontinuation (e.g., rebound anxiety, insomnia, irritability, tremors, seizures)
Special Patient Groups
Pregnancy
Alprazolam is classified as Pregnancy Category D. It should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
Trimester-Specific Risks:
Lactation
Alprazolam and its active metabolites are excreted into breast milk. Use during breastfeeding is generally not recommended, or should be done with extreme caution and close infant monitoring.
Pediatric Use
Safety and efficacy have not been established in pediatric patients. Use is generally not recommended due to potential for adverse effects and lack of data. If used, it should be under strict specialist supervision for specific indications.
Geriatric Use
Elderly patients are more sensitive to the effects of benzodiazepines and may experience increased risk of sedation, dizziness, cognitive impairment, and falls. Lower initial doses (e.g., 0.25 mg BID or TID) are recommended, and titration should be done slowly with close monitoring. The half-life of alprazolam may be prolonged in the elderly.
Clinical Information
Clinical Pearls
- Alprazolam has a relatively short half-life among benzodiazepines, which can lead to inter-dose withdrawal symptoms or rebound anxiety, especially with higher doses or less frequent dosing.
- Due to its rapid onset of action and high potency, alprazolam has a significant potential for abuse, misuse, and physical dependence. It is a Schedule IV controlled substance.
- Physical dependence can develop even with therapeutic doses and short-term use. Tapering off the medication slowly is crucial to minimize withdrawal symptoms, which can include seizures.
- Not typically recommended as first-line for long-term generalized anxiety disorder; often used for acute anxiety or panic attacks, or as an adjunct to other therapies (e.g., antidepressants).
- Patients should be educated about the risks of concomitant use with alcohol and other CNS depressants, including opioids, due to the risk of severe respiratory depression and death.
Alternative Therapies
- Other benzodiazepines (e.g., lorazepam, clonazepam, diazepam) for anxiety/panic disorders.
- Selective Serotonin Reuptake Inhibitors (SSRIs) or Serotonin-Norepinephrine Reuptake Inhibitors (SNRIs) as first-line long-term treatment for anxiety and panic disorders.
- Buspirone (for generalized anxiety disorder, non-addictive).
- Hydroxyzine (antihistamine with anxiolytic properties).
- Beta-blockers (e.g., propranolol) for somatic symptoms of anxiety.
- Cognitive Behavioral Therapy (CBT) and other psychotherapies.
- Lifestyle modifications (e.g., exercise, mindfulness, stress management techniques).
