1. WHAT SEROQUEL® TABLETS ARE AND WHAT THEY ARE USED FOR
Seroquel® Tablets contain a substance called quetiapine. This belongs to a group of medicines called anti-psychotics. Seroquel® Tablets can be used to treat several illnesses, such as:
• Bipolar depression: where you feel sad. You may find that you feel depressed, feel guilty, lack energy, lose your appetite or can’t sleep.
• Mania: where you may feel very excited, elated, agitated, enthusiastic or hyperactive or have poor judgment including being aggressive or disruptive.
• 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.
Your doctor may continue to prescribe Seroquel® Tablets even when you are feeling better.
2. WHAT YOU NEED TO KNOW BEFORE YOU TAKE SEROQUEL® TABLETS
Do not take Seroquel® Tablets:
• If you are allergic (hypersensitive) to quetiapine or any of the other ingredients of Seroquel® Tablets (see Section 6: Further information).
• If you are taking any of the following medicines:
some medicines for HIV azole medicines (for fungal infections) erythromycin or clarithromycin (for infections) nefazodone (for depression).
Do not take Seroquel® Tablets if the above applies to you. If you are not sure, talk to your doctor or pharmacist before taking Seroquel® Tablets.
Warnings and Precautions
Talk to your doctor or pharmacist before taking Seroquel® Tablets if:
• You, or someone in your family, have or have had any heart problems, for example heart rhythm problems, weakening of the heart muscle or inflammation of the heart or if you are taking any medicines that may have an impact on the way your heart beats.
• 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 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® Tablets.
• 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 are an elderly person with dementia (loss of brain function). If you are, Seroquel® Tablets should not be taken because the group of medicines that Seroquel belongs to may increase the risk of stroke, or in some cases the risk of death, in elderly people with dementia.
• 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.
• You have or have had a condition where you stop breathing for short periods during your normal nightly sleep (called “sleep apnoea”) and are taking medicines that slow down the normal activity of the brain (“depressants”).
• You have or have had a condition where you can’t completely empty your bladder (urinary retention), have an enlarged prostate, a blockage in your intestines, or increased pressure inside your eye. These conditions are sometimes caused by medicines (called “anticholinergics”) that affect the way nerve cells function in order to treat certain medical conditions.
Tell your doctor immediately if you experience any of the following after taking Seroquel® Tablets:
• 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.
• Uncontrollable movements, mainly of your face or tongue.
• Dizziness or a severe sense of feeling sleepy. This could increase the risk of accidental injury (fall) in elderly patients.
• Fits (seizures).
• A long-lasting and painful erection (Priapism).
These conditions can be caused by this type of medicine.
Tell your doctor as soon as possible if you have:
• A fever, flu-like symptoms, sore throat, or any other infection, as this could be a result of a very low white blood cell count, which may require Seroquel® Tablets to be stopped and/or treatment to be given.
• Constipation along with persistent abdominal pain, or constipation which has not responded to treatment, as this may lead to a more serious blockage of the bowel.
Thoughts of suicide and worsening of your depression
If you are depressed you may sometimes have thoughts of harming or killing yourself. These may be increased when first starting treatment, since these medicines all take time to work, usually about two weeks but sometimes longer. 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.
