1. What is Xanax and what is it used for

The active substance of Xanax is alprazolam. It belongs to a group of medicines called benzodiazepines (medicines with anxiolytic activity). Xanax is indicated for the treatment of symptoms of anxiety disorders in adults, only in situations where the symptoms are severe, prevent normal functioning, or are very troublesome for the patient. This medicine is intended for short-term use only.

2. Important information before taking Xanax

When not to take Xanax

• if the patient is allergic to alprazolam and other benzodiazepines, or any of the other ingredients of this medicine (listed in section 6);
• if the patient has myasthenia gravis (a disease characterized by excessive muscle fatigue and weakness);
• if the patient has severe respiratory failure;
• if the patient has sleep apnea syndrome;
• if the patient has severe liver failure.

Xanax should not be used in children and adolescents under 18 years of age.

Warnings and precautions

Before starting treatment with Xanax, the patient should discuss it with their doctor:

• if the medicine is used for a long time, as dependence on the medicine may occur, especially in patients prone to drug or alcohol abuse. The need for further treatment should be periodically assessed by the doctor;
• if the dose of the medicine is reduced or it is suddenly discontinued (possible occurrence of withdrawal symptoms (see section 4));

There have been reports of episodes of hypomania and mania in association with the use of Xanax in patients with depression. Before planned surgery, the patient should inform their doctor about taking Xanax.

Xanax and other medicines

The patient should tell their doctor about all medicines they are currently taking or have recently taken, as well as any medicines they plan to take.

• Particular caution should be exercised when using Xanax with opioids, as they have a depressant effect on the respiratory system (slowing and shallow breathing). This is associated with a risk of excessive sedation, respiratory depression, coma, and even death.
• Xanax may enhance the effects of antipsychotic, sedative, anxiolytic, antidepressant, narcotic analgesic, anticonvulsant, anesthetic, and antihistamine medicines.
• In the case of narcotic analgesics, there may be an increase in euphoria, which can lead to increased psychological dependence.
• Alcohol should not be consumed during treatment with Xanax.
• It is not recommended to take Xanax with certain oral antifungal medicines (e.g., ketoconazole, itraconazole, posaconazole, voriconazole).
• Particular caution should be exercised and the dose reduced when using Xanax with nefazodone, fluvoxamine, and cimetidine.
• Particular caution should be exercised when using alprazolam with fluoxetine, propoxyphene, oral contraceptives, sertraline, diltiazem, and macrolide antibiotics (e.g., erythromycin, clarithromycin, or troleandomycin).
• The concomitant use of Xanax and HIV protease inhibitors (e.g., ritonavir) requires dose modification or discontinuation of alprazolam.
• Patients taking alprazolam and digoxin should be closely monitored for signs of digoxin toxicity.
• Theophylline may decrease the effect of benzodiazepines.

The use of Xanax during pregnancy is not recommended. If the medicine is used during pregnancy or if the patient becomes pregnant while taking alprazolam, they should be examined for potential fetal risk. If it is necessary to administer the medicine in the last trimester of pregnancy, high doses should be avoided and the newborn should be monitored. Benzodiazepines pass into breast milk in small amounts. Xanax should not be used during breastfeeding.

When starting treatment, the doctor will inform the patient about the limited duration of therapy, the gradual reduction of the dose during withdrawal, and the possibility of withdrawal reactions.

If severe side effects occur after administration of the initial dose, the doctor may decide to reduce the dose.
