Quetiapine

About quetiapine

Quetiapine belongs to a group of medicines called antipsychotics. It may have been prescribed for you to relieve the symptoms of schizophrenia or, alternatively, for a mood disorder such as mania or depression. In all of these conditions, quetiapine works on the balance of chemical substances in your brain.

Quetiapine is available as standard-release tablets (which are generally taken twice daily) and also as modified-release tablets (which are taken once daily). Modified-release tablets have the letters 'XL' after the brand name - these release quetiapine more slowly and evenly throughout the course of the day.

Before taking quetiapine

Some medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start taking quetiapine it is important that your doctor knows:

• Wenn Sie schwanger sind oder stillen.

• If you have a heart problem or blood vessel disease.

• If you have had a stroke, or if you have been told you have 'thickening' of the blood vessels to your brain.

• Wenn Sie Leber-, Nieren- oder Prostataprobleme haben.

• If you have any problems with your breathing, or if you have any difficulties swallowing.

• If you have breathing difficulties whilst sleeping (sleep apnoea).

• If you have any of the following: epilepsy, Parkinson's disease, raised pressure in your eye (glaucoma) or a condition which causes muscle weakness, called myasthenia gravis.

• Wenn Sie jemals eine Gelbfärbung der Haut oder des Augenweißes (Gelbsucht) oder eine Blutkrankheit hatten.

• wenn Sie einen Tumor an der Nebenniere haben (ein so genanntes Phäochromozytom).

• If you have had problems with alcohol or drug abuse.

• Wenn Sie eine allergische Reaktion auf ein Arzneimittel hatten.

• Wenn Sie andere Arzneimittel einnehmen oder verwenden. Dazu gehören alle Arzneimittel, die Sie einnehmen und die rezeptfrei erhältlich sind, sowie pflanzliche und ergänzende Arzneimittel.

How to take quetiapine

• Before you start the treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about quetiapine and it will also provide you with a full list of the side-effects which you may experience from taking it.

• Take quetiapine exactly as your doctor tells you to. It is taken once or twice a day depending upon the type of tablet prescribed. There are several different strengths of tablet available so your doctor will prescribe a dose to suit your condition. The directions for taking the tablets will be printed on the label of the pack to remind you about what the doctor said to you.

• Try to get into the habit of taking your doses at the same times of day each day, as this will help you to remember to take them regularly. If you are taking quetiapine for depression, you should take your doses at bedtime.

• Standard-release quetiapine tablets (these are usually taken twice daily) can be taken either before or after meals.

• If you have been given prolonged-release tablets (these have the letters 'XL' after the brand name) you must swallow the tablet whole when your stomach is empty. This means that you should not chew or break the tablet before your swallow it, and that you should take each of your doses at least an hour before a meal, or wait until two hours afterwards.

• If you have been given the oral liquid medicine, use the dosing syringe or cup to measure your dose accurately. The medicine can be taken either before or after meals.

• Do not drink grapefruit juice while you are on quetiapine. This is because a chemical in grapefruit is likely to increase the amount of quetiapine in your bloodstream and make side-effects more likely.

• Wenn Sie die Einnahme einer Dosis vergessen haben, nehmen Sie sie ein, sobald Sie sich daran erinnern, es sei denn, es ist fast Zeit für die nächste Dosis; in diesem Fall lassen Sie die vergessene Dosis aus. Nehmen Sie nicht zwei Dosen zusammen ein, um eine vergessene Dosis auszugleichen.

Das Beste aus Ihrer Behandlung herausholen

• Your treatment will require careful monitoring to make sure that you get the best possible benefit from quetiapine. Keep your regular doctor's appointments so that your progress can be checked. You will need to have some tests from time to time.

• Quetiapine tablets come in different strengths and colours. If your dose is changed, your tablets may look different. If you are unsure about your tablets at any time, please ask your pharmacist for advice.

• Treatment with quetiapine is usually long-term unless you experience an adverse effect. Keep taking the tablets unless your doctor tells you otherwise. Stop taking quetiapine suddenly can cause problems so your doctor may want you to reduce your dose gradually if this becomes necessary.

• If you drink alcohol, ask your doctor for advice. Alcohol may increase the risk of side-effects from quetiapine so it is best avoided.

• If you have diabetes you may need to check your blood glucose more frequently, as quetiapine may affect the levels of sugar in your blood. Your doctor will advise you about this.

• Some medicines similar to quetiapine can cause the skin to become more sensitive to sunlight than normal. It may be advisable to use a sunscreen in bright sunlight until you know how your skin reacts.

• If you are due to have any medical or dental treatment, tell the person carrying out the treatment which medicines you are taking. This is important because quetiapine may interfere with any anaesthetic you receive.

• If you buy or take any 'over-the-counter' medicines or herbal remedies, please check with a pharmacist that they are suitable for you to take with quetiapine.

• A small number of people taking medicines for mood disorders can have thoughts about harming themselves or ending their lives, particularly when a new medicine is started. It is very important that you tell your doctor about this if it happens to you.

Can quetiapine cause problems?

Along with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them. The table below contains some of the most common ones associated with quetiapine. You will find a full list in the manufacturer's information leaflet supplied with your medicine. The unwanted effects often improve as your body adjusts to the new medicine, but speak with your doctor or pharmacist if any of the following continue or become troublesome.

Wenn Sie andere Symptome haben, von denen Sie glauben, dass sie auf die Tabletten zurückzuführen sind, sprechen Sie bitte mit Ihrem Arzt oder Apotheker, um weiteren Rat einzuholen.

How to store quetiapine

• Bewahren Sie alle Arzneimittel außerhalb der Reichweite und Sichtweite von Kindern auf.

• An einem kühlen, trockenen Ort aufbewahren, vor direkter Hitze und Licht schützen.
