What are the uses of this medicine?[edit | edit source]

Alprazolam (Xanax) is a prescription medicine used:

  • to treat anxiety disorders
  • for the short-term relief of the symptoms of anxiety
  • to treat panic disorder with or without a fear of places and situations that might cause panic, helplessness, or embarrassment (agoraphobia)

Limitations of use:

  • Xanax is a federal controlled substance (C-IV) because it contains alprazolam that can be abused or lead to dependence.
  • Elderly patients are especially susceptible to dose related adverse effects when taking Xanax.
  • It is not known if Xanax is safe and effective when used to treat anxiety disorder for longer than 4 months.
  • It is not known if Xanax is safe and effective when used to treat panic disorder for longer than 10 weeks.

How does this medicine work?[edit | edit source]

  • Alprazolam (al pra' zoe lam) is a benzodiazepine that is widely used in the therapy of anxiety and panic disorder.
  • Alprazolam is a triazolobenzodiazepine agent with anxiolytic, sedative-hypnotic and anticonvulsant activities.
  • Alprazolam binds to a specific site distinct from the inhibitory neurotransmitter gamma-aminobutyric acid (GABA) binding site on the benzodiazepine-GABA-A-chloride ionophore receptor complex located in the limbic, thalamic and hypothalamic regions of the central nervous system (CNS).
  • This binding causes an allosteric modification of the receptor and enhances the affinity of GABA to the receptor leading to an increase in the frequency of chloride-channel opening events.
  • This leads to an increase in chloride ion conductance, neuronal hyperpolarization, inhibition of the action potential and leads to a decrease in neuronal excitability.

Who Should Not Use this medicine ?[edit | edit source]

This medicine cannot be used in patients who:

  • are allergic to alprazolam, other benzodiazepines, or any of the ingredients in Xanax.

What special precautions should I follow?[edit | edit source]

  • Xanax can make you sleepy or dizzy and can slow your thinking and motor skills. Do not drive, operate heavy machinery, or do other dangerous activities until you know how Xanax affects you.
  • Do not drink alcohol or take other drugs that may make you sleepy or dizzy while taking Xanax without first talking to your healthcare provider. When taken with alcohol or drugs that cause sleepiness or dizziness, Xanax may make your sleepiness or dizziness much worse.
  • Use of Xanax during later stages of pregnancy can result in sedation (respiratory depression, lethargy, hypotonia) and withdrawal symptoms (hyperreflexia, irritability, restlessness, tremors, inconsolable crying, and feeding difficulties) in the neonate.
  • Benzodiazepines may worsen depression. Panic disorder has been associated with primary and secondary major depressive disorders and increased reports of suicide among untreated patients.
  • Episodes of hypomania and mania have been reported in association with the use of Xanax in patients with depression.
  • 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.
  • To reduce the risk of withdrawal reactions, use a gradual taper to discontinue Xanax or reduce the dosage.
  • Concomitant use of benzodiazepines, including Xanax, and opioids may result in profound sedation, respiratory depression, coma, and death. Advise both patients and caregivers about the risks of respiratory depression and sedation when Xanax is used with opioids.
  • Xanax passes into your breast milk and may harm your baby. Talk to your healthcare provider about the best way to feed your baby if you take Xanax. You should not breastfeed while taking Xanax.
  • As with most benzodiazepines, alprazolam therapy has not been associated with serum aminotransferase or alkaline phosphatase elevations, and clinically apparent liver injury from alprazolam has been reported, but is very rare.

What to do in case of emergency/overdose?[edit | edit source]

Symptoms of overdosage may include:

  • somnolence, confusion, impaired coordination, diminished reflexes, and coma.
  • Death has been reported in association with overdoses of alprazolam by itself, as it has with other benzodiazepines.

Management of overdosage:

  • In case of overdose, call the poison control helpline of your country. In the United States, call 1-800-222-1222.
  • Overdose related information is also available online at poisonhelp.org/help.
  • In the event that the victim has collapsed, had a seizure, has trouble breathing, or can't be awakened, immediately call emergency services. In the United States, call 911.
  • Respiration, pulse rate, and blood pressure should be monitored.
  • General supportive measures should be employed, along with immediate gastric lavage. Intravenous fluids should be administered and an adequate airway maintained.
  • Flumazenil may be useful in situations when an overdose with a benzodiazepine is known or suspected.
  • Patients treated with flumazenil should be monitored for re-sedation, respiratory depression, and other residual benzodiazepine effects for an appropriate period after treatment.

Can this medicine be used in pregnancy?[edit | edit source]

  • Overall available data from published observational studies of pregnant women exposed to alprazolam have not established a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes.
  • Benzodiazepines cross the placenta and may produce respiratory depression and sedation in neonates.

Can this medicine be used in children?[edit | edit source]

  • Safety and effectiveness of Xanax have not been established in pediatric patients.
