1.    What Xanax is and what it is used for

•    Xanax is a tranquilliser containing the active ingredient alprazolam. Alprazolam belongs to one of a group of medicines called benzodiazepines. Benzodiazepines affect chemical activity in the brain to promote sleep and to reduce anxiety and worry.

•    Xanax tablets are only used to treat severe anxiety and severe anxiety associated with depression. Xanax is not recommended for the treatment of depression.

•    Xanax tablets should only be used for short-term treatment of anxiety. The overall duration of treatment should not be more than 12 weeks including a period where the dose is gradually reduced (this is called dose ‘tapering’).

2.    What you need to know before you take Xanax

Do not take Xanax:

•    If you are allergic to alprazolam or other similar benzodiazepine medicines, or to any of the other ingredients of this medicine (listed in section 6).

•    If you suffer from a disease called ‘myasthenia gravis’ where you suffer from very weak and tired muscles.

•    If you have severe chest problems or breathing difficulties (e.g. chronic bronchitis or emphysema).

•    If you have severe liver problems.

•    If you have ‘sleep apnoea’ - this is a condition where your breathing becomes irregular, even stopping for short periods, while you are asleep.

•    If you are pregnant, think you might be pregnant now, are planning to become pregnant or if you are breast-feeding (see also the sections on ‘Pregnancy’ and ‘Breast-feeding’ for more information).

Warnings and precautions

Talk to your doctor or pharmacist before taking Xanax if you:

•    have ever felt so depressed that you have thought about taking your own life.

•    have ever suffered any mental illness that required hospital treatment.

•    have problems with your lungs, kidneys or liver.

•    have abused drugs or alcohol in the past or find it difficult to stop taking medicines, drinking or taking drugs. Your doctor may want to give you special help when you need to stop taking these tablets.

•    have been prescribed medicines for severe anxiety before, because your body can quickly become used to this type of medicine so that it no longer helps you.

Children and adolescents

Alprazolam is not recommended for children and adolescents under the

age of 18 years.

Other medicines and Xanax

Tell your doctor or pharmacist if you are taking, have recently taken or might

take any other medicines, especially medicines listed below, as the effect

of Xanax or the other medicine may change when taken at the same time:

•    any other medicines to treat anxiety or depression or to help you sleep (e.g. nefazodone, fluvoxamine, fluoxetine).

•    some strong pain killers (e.g. morphine, codeine or propoxyphene).

•    antipsychotic medicines used to treat mental illnesses like schizophrenia.

•    medicines to treat epilepsy.

•    antihistamines for relief of allergies.

•    medicines for treating fungal infections (e.g. ketoconazole).

•    oral contraceptives (‘the pill’).

•    certain antibiotics (e.g. erythromycin).

•    cimetidine (for treating stomach ulcers).

•    diltiazem (used for angina and high blood pressure).

•    digoxin (used to treat various heart conditions).

•    ritonavir or other similar medicines used for treating HIV.

If you are going to have an operation where you will be given a general anaesthetic, tell your doctor or anaesthetist that you are taking Xanax.

Taking Xanax with food, drink and alcohol

It is important not to drink any alcohol while you are taking Xanax, as alcohol increases the effects of the medicine.

Pregnancy

If you are pregnant, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine, because Xanax may be harmful to the developing baby.

Breast-feeding

Do not breast-feed while taking Xanax, as the drug may pass into breast milk. Driving and using machines

Xanax can make you feel sleepy or woozy and make you lose concentration so it is very important you do not operate machinery until you know how the tablets affect you.

Xanax can affect your ability to drive as it may make you sleepy or dizzy.

•    Do not drive while taking this medicine until you know how it affects you.

•    It is an offence to drive if this medicine affects your ability to drive.

•    However, you would not be committing an offence if:

o The medicine has been prescribed to treat a medical or dental problem and

o You have taken it according to the instructions given by the prescriber or in the information provided with the medicine and o It was not affecting your ability to drive safely

Talk to your doctor or pharmacist if you are not sure whether it is safe for you to drive while taking this medicine.

Xanax contains lactose monohydrate

Xanax contains an ingredient known as lactose monohydrate which is a type of sugar. If you have been told by your doctor that you have an intolerance to some sugars contact your doctor before taking this medicinal product

3. How to take Xanax

Always take this medicine exactly as your doctor has told you. Check with your doctor or pharmacist if you are not sure. Your doctor will tell you how many tablets to take and when to take them. This information is also on the label of the carton the tablets come in.

Do not take your tablets with an alcoholic drink.

Adults

You will usually start by taking one 250 microgram or one 500 microgram tablet three times a day. This gives a total dose of 750 micrograms to 1500 micrograms each day.

If clinically required your doctor may increase your medicine in small increments. Where the dose does need to be increased, it is usual to increase the night time dose first, before the daytime doses to make sure you are more alert during the day. If you start to get side effects the doctor may lower your dose.

The elderly

If you are an older patient or you have for example kidney or liver problems and you need a lower dose you will normally start on a dose of 250 micrograms two or three times a day. This dose may be slowly increased if needed and if you do not get any side effects.

Use in children and adolescents

Alprazolam is not recommended for children and adolescents under the age of 18 years.

If you take more Xanax than you should

It is important that you do not take more tablets than you are told to. If you do accidentally take too many tablets you may experience drowsiness, confusion, feeling cold, slurred speech, drop in blood pressure and difficulty breathing. If you do accidentally take too many tablets, seek medical attention straight away.

If you forget to take Xanax

If you forget to take a dose, take it as soon as you remember unless it is time for your next dose. Do not take a double dose to make up for a missed dose.

Length of treatment

•    Xanax tablets are only used for short-term treatment (not more than 12 weeks). You will not normally be given a prescription for more than 4 weeks and you will be regularly reviewed by your doctor during this time. A decreased effect of the drug may develop if used for more than a few weeks.

If you stop taking Xanax

Always see your doctor before you stop taking Xanax tablets as the dose needs to be reduced gradually. If you stop taking the tablets or reduce the dose suddenly you can get ‘rebound’ effects which might cause you to become temporarily more anxious or restless or to have difficulty sleeping. These symptoms will go away as your body re-adjusts. If you are worried, your doctor can tell you more about this.

If you have any further questions on the use of this medicine, ask your doctor or pharmacist.

4. Possible side effects

Like all medicines this medicine can cause side effects although not everyone gets them, and if you do get them they may differ in intensity for different people.

Reasons for stopping Xanax treatment immediately If you get any of these symptoms see your doctor straight away as treatment will need to be discontinued. Your doctor will then advise how treatment will be stopped.
