Seroquel contains a substance called quetiapine. This belongs to a group of medicines called anti-psychotics. Seroquel can be used to treat several illnesses, such as:
• Schizophrenia: where you may hear or feel things that are not there, believe things that are not true or feel unusually suspicious, anxious, confused, guilty, tense or depressed.
• Mania: where you may feel very excited, elated, agitated, enthusiastic or hyperactive or have poor judgment including being aggressive or disruptive.
• Bipolar depression: where you may feel sad all the time or you may find that you feel depressed, feel guilty, lack energy, lose your appetite or can’t sleep.
Your doctor may continue to prescribe Seroquel even when you are feeling better.

- azole medicines (for fungal infections)
- medicines for an infection (like erythromycin or clarithromycin)
- nefazodone (for depression).
Do not take Seroquel if the above applies to you. If you are not sure, talk to your doctor or pharmacist before taking Seroquel.

• You have low blood pressure.
• You have had a stroke, especially if you are elderly.
• You have problems with your liver.
• You have ever had a fit (seizure).
• You know that you have had low levels of white blood cells in the past (which may or may not have been caused by other medicines).
• You have diabetes or have a risk of getting diabetes. If you do, your doctor may check your blood sugar levels while you are taking Seroquel.

• You or someone else in your family has a history of blood clots, as medicines like these have been associated with formation of blood clots.
Tell your doctor immediately if you experience any of the following after taking Seroquel:
• A combination of fever, severe muscle stiffness, sweating or a lowered level of consciousness (a disorder called “neuroleptic malignant syndrome”). Immediate medical treatment may be needed.

These thoughts may also be increased if you suddenly stop taking your medication. You may be more likely to think like this if you are a young adult. Information from clinical trials has shown an increased risk of suicidal thoughts and/or suicidal behaviour in young adults aged less than 25 years with depression.
If you have thoughts of harming or killing yourself at any time, contact your doctor or go to a hospital straight away. You may find it helpful to tell a relative or close friend that you are depressed, and ask them to read this leaflet. You might ask them to tell you if they think your depression is getting worse, or if they are worried about changes in your behaviour.

Some side effects are only seen when a blood test is taken. These include changes in the amount of certain fats (triglycerides and total cholesterol) or sugar in the blood, changes in the amount of thyroid hormones in your blood, increased liver enzymes, decreases in the number of certain types of blood cells, decrease in the amount of red blood cells, increased blood creatine phosphokinase (a substance in the muscles), decrease in the amount of sodium in the blood, and increases in the amount of the hormone prolactin in the blood. Increases in the hormone prolactin could in rare cases lead to the following:

Your doctor may ask you to have blood tests from time to time.
