1. What Xanax is and what it is used for

The active substance in Xanax is alprazolam. It belongs to a group of medicines called benzodiazepines (medicines with anxiolytic properties).
Xanax is indicated for the treatment of symptoms of anxiety disorders in adults, but only in cases where symptoms are severe, impair normal functioning, or cause significant distress to the patient. This medicine is intended for short-term use only.

2. Important information before using Xanax

When not to use Xanax

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

Xanax must not be used in children and adolescents under 18 years of age.
Warnings and precautions
Before starting treatment with Xanax, discuss the following with your doctor:

• if the medicine is to be used long-term, as dependence on the medicine may occur, especially in patients prone to drug or alcohol abuse. The need for continued treatment should be periodically assessed by the doctor;
• if the dose is being reduced or the medicine is suddenly discontinued [withdrawal symptoms may occur (see section 4)];

Page 1 of 7

• if the medicine is used in patients with depression, suicidal thoughts or tendencies;
• if the patient is taking other benzodiazepines (increased risk of dependence);
• if the patient is simultaneously taking opioids, hypnotics, sedatives, or consuming alcohol (the effects of these medicines or alcohol may be intensified);
• if restlessness, psychomotor agitation, irritability, aggression, rage, hallucinations, nightmares, delusions, psychosis, inappropriate behaviour or other behavioural disturbances occur. If any of these symptoms appear, treatment with the medicine should be discontinued and the patient should contact their doctor;
• if the patient has glaucoma;
• if the patient has impaired kidney or liver function. Like other benzodiazepines, Xanax may cause anterograde amnesia, which occurs several hours after taking the medicine. In such a case, the patient should have an uninterrupted sleep of 7–8 hours. Benzodiazepines and similar-acting substances should be used with caution in elderly patients due to the risk of excessive sedation and (or) weakening of the musculoskeletal system, which may lead to falls, often with serious consequences for such patients.

Episodes of hypomania and mania have been reported in connection with the use of Xanax in patients with depression.
Before a planned surgery, inform the doctor about taking Xanax.
Xanax and other medicines
Tell your doctor about all medicines the patient is currently taking or has recently taken, as well as any medicines the patient plans to take.

• Extreme caution should be exercised when using Xanax together with opioids, as they have a depressive effect on the respiratory system (slowing and weakening breathing). This is associated with the risk of excessive sedation, respiratory depression, coma, and even death.
• Xanax may enhance the effects of antipsychotics, hypnotics, anxiolytics, sedatives, antidepressants, narcotic analgesics, anticonvulsants, anaesthetics, and antihistamines.
• When narcotic analgesics are used, euphoria may be intensified, which may lead to increased psychological dependence.
• Alcohol must not be consumed during treatment with Xanax.
• Concomitant use of Xanax with certain systemic antifungal medicines (e.g. ketoconazole, itraconazole, posaconazole, voriconazole) is not recommended.
• Extreme caution should be exercised and dose reduction considered when using Xanax together with nefazodone, fluvoxamine, and cimetidine.
• Extreme caution should be exercised when using alprazolam together with fluoxetine, propoxyphene, oral contraceptives, sertraline, diltiazem, and macrolide antibiotics (e.g. erythromycin, clarithromycin, or troleandomycin).
• Concomitant use of Xanax and HIV protease inhibitors (e.g. ritonavir) requires dose adjustment or discontinuation of alprazolam.
• Patients taking alprazolam and digoxin simultaneously should be closely monitored for (objective and subjective) signs of digoxin toxicity.
• Theophylline may reduce the effect of benzodiazepines.

Pregnancy and breastfeeding
If the patient is pregnant or breastfeeding, suspects she may be pregnant, or is planning to have a child, she should consult her doctor before using this medicine.
Use of this medicine during pregnancy is not recommended.

Benzodiazepines pass into human milk in small concentrations.
Xanax must not be used during breastfeeding.

Before using Xanax, patients should familiarize themselves with current local traffic regulations.
Patients should not drive or operate machinery while taking Xanax.
Xanax contains lactose monohydrate
If the patient has previously been diagnosed with intolerance to certain sugars, the patient should consult their doctor before taking this medicine.

Each tablet of this medicine contains 0.11 mg of sodium benzoate.

3. How to use Xanax

This medicine should always be used exactly as prescribed by your doctor.
If you have any doubts, consult your doctor or pharmacist.
Xanax is available in the following doses: 0.25 mg, 0.5 mg, 1 mg, 2 mg.
Treatment should be as short as possible. Your doctor should regularly assess your condition and the need for continuing treatment, especially if your symptoms have improved and may no longer require pharmacological treatment. The total duration of treatment should not exceed 2–4 weeks. Long-term treatment is not recommended.
At the start of treatment, your doctor will inform you about the limited duration of therapy, the need for gradual dose reduction when discontinuing the medicine, and the possibility of withdrawal reactions.
When using benzodiazepines, including Xanax, dependence may develop, as well as emotional or physical dependence. This risk increases with higher doses and longer treatment duration. Therefore, the lowest effective dose should be used for the shortest possible time, and the need for continued treatment should be regularly reviewed with your doctor.

Recommended dose
The dose is determined by the doctor based on the severity of symptoms and the individual patient's response to treatment. If severe adverse effects occur after the initial dose, the doctor may decide to reduce the dose.

Treatment of anxiety symptoms
The recommended starting dose is 0.25 mg or 0.5 mg three times daily.
The doctor may decide to increase the dose, depending on the patient's needs, up to a maximum daily dose of 4 mg, divided into smaller doses taken throughout the day.

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

Use in patients with renal or hepatic impairment
Use in patients with severe liver impairment is contraindicated.

Use in elderly patients
The recommended starting dose is 0.25 mg two or three times daily.
If necessary, the doctor may decide to gradually increase the dose depending on the patient's tolerance. If adverse effects occur, the doctor may decide to reduce the initial dose.

Use of a higher than recommended dose of Xanax
Taking a higher than recommended dose of Xanax may cause: ataxia (impaired coordination), drowsiness, speech disturbances, coma, and respiratory depression. If any concerning symptoms occur, contact your doctor immediately.

Missed dose of Xanax
Do not take a double dose to make up for a missed dose.

Discontinuing Xanax
Do not stop taking Xanax on your own.
Since treatment is symptomatic, symptoms may return after stopping the medicine.
Your doctor will decide on a gradual dose reduction.

If you have any further doubts regarding the use of this medicine, consult your doctor.

Benzodiazepines may cause physical and psychological dependence.

If physical dependence develops, abrupt discontinuation of Xanax may lead to withdrawal symptoms: headache, muscle pain, increased anxiety, feelings of tension, agitation, disorientation, irritability, depersonalization or derealization, hearing disturbances, stiffness and tingling of limbs, hypersensitivity to light, noise, and touch, hallucinations and seizures, insomnia, and mood changes.

These symptoms are usually more pronounced in patients treated long-term with high doses of benzodiazepines and in cases of abrupt or rapid discontinuation of the medicine.
