1. What Seroquel Prolong is and what it is used for
Seroquel Prolong contains a substance called quetiapine. It belongs to a group of medicines called antipsychotics. Seroquel Prolong can be used to treat several diseases, such as:
- Bipolar depression and major depressive episodes in major depressive disorder: for which you feel sad. You may find that you feel depressed, feel guilty, lack energy, lose your appetite, or cannot sleep.
- Mania: for which you may feel very excited, euphoric, agitated, enthusiastic, or hyperactive, or show poor judgment, including being aggressive or violent.
- Schizophrenia: for which you may hear or feel things that are not there, believe things that are not true, or feel abnormally suspicious, anxious, confused, guilty, tense, or depressed.
When Seroquel Prolong is used to treat major depressive episodes in major depressive disorder, it will be taken in addition to another medication that is being used to treat this disease.
Your doctor may continue to prescribe Seroquel Prolong even when you are feeling better.
2. What you need to know before you take Seroquel Prolong
Do not take Seroquel Prolong:
- if you are allergic to quetiapine or any of the other ingredients of this medicine (listed in section 6)
- if you are taking any of the following medicines:
- Some medicines for HIV
- Medicines of the azole type (for fungal infections)
- Erythromycin or clarithromycin (for infections)
- Nefazodone (for depression).
If you are in doubt, consult your doctor or pharmacist before taking Seroquel Prolong.
Warnings and precautions
Consult your doctor or pharmacist before starting to take Seroquel Prolong:
- if you, or a family member, have or have had any heart problems, such as heart rhythm problems, heart muscle weakness, or heart inflammation, or if you are taking any medication that may affect your heart rhythm.
- if you have low blood pressure.
- if you have had a stroke, especially if you are elderly.
- if you have liver problems.
- if you have ever had a seizure (convulsion).
- if you have diabetes or are at risk of developing diabetes. If so, your doctor may monitor your blood sugar levels while you are taking Seroquel Prolong.
- if you know you have had low white blood cell counts in the past (which may or may not have been caused by other medications).
- if you are an elderly person with dementia (loss of brain function). If so, you should not take Seroquel Prolong because the group of medicines to which Seroquel Prolong belongs may increase the risk of stroke, or in some cases the risk of death, in these people.
- if you are an elderly person with Parkinson's disease/parkinsonism.
- if you or a family member have a history of blood clots, as medicines like this one have been associated with the formation of blood clots.
- if you have or have had a condition in which your breathing is interrupted for short periods during normal nighttime sleep (called "sleep apnea") and are taking medications that reduce normal brain activity ("depressants").
- if you have or have had a condition in which you cannot empty your bladder completely (urinary retention), have an enlarged prostate, a blockage in your intestine, or high pressure inside your eye. These conditions may be caused by medications (called "anticholinergics") that affect how nerve cells work, to treat certain medical conditions.
- if you have a history of alcohol or drug abuse.
- if you have depression or other conditions that are treated with antidepressants.
The use of these medicines together with Seroquel Prolong may cause serotonin syndrome, a potentially life-threatening condition (see "Other medicines and Seroquel Prolong").
Tell your doctor immediately if after taking Seroquel Prolong you experience any of the following:
- A combination of fever, severe muscle stiffness, sweating, or a decrease in the level of consciousness (a disorder called "neuroleptic malignant syndrome"). You may need immediate medical treatment.
- Uncontrolled movements, mainly of your face or tongue.
- Dizziness or feeling very drowsy. This can increase the risk of accidental injuries (falls) in elderly patients.
- Seizures (convulsions).
- A prolonged and painful erection (priapism).
- Rapid and irregular heartbeats, even when you are at rest, palpitations, breathing problems, chest pain, or unexplained tiredness. Your doctor should examine your heart and, if necessary, refer you to a cardiologist immediately.
These disorders may be caused by this type of medicine.
Tell your doctor as soon as possible if you have:
- Fever, flu-like symptoms, sore throat, or any other infection, as it could be a consequence of a very low white blood cell count and may require interruption of treatment with Seroquel Prolong and/or additional treatment.
- Constipation along with persistent abdominal pain, or constipation that has not responded to treatment, as it could lead to a more serious intestinal blockage.
- Thoughts of suicide and worsening of your depression
If you are depressed, you may sometimes think about harming yourself or committing suicide. This can increase when you first start treatment, as all these medicines take time to work, usually around two weeks but sometimes more. These thoughts can also increase if you stop taking your medication abruptly. You are more likely to think this way if you are a young adult. Information from clinical trials has shown an increased risk of suicidal thoughts and/or suicidal behavior in young adults under 25 years of age with depression.
If at any time you think about harming yourself or committing suicide, contact your doctor or go to a hospital immediately. It may help to tell a close relative or friend that you are depressed and ask them to read this leaflet. You can ask them to tell you if they think your depression is getting worse, or if they are worried about changes in your behavior.
Severe skin reactions (SCARs)
With the use of this medicine, very rare but serious skin reactions (SCARs) have been reported, which can be life-threatening or fatal. These are commonly manifested as:
- Stevens-Johnson syndrome (SSJ), a widespread rash with blisters and peeling of the skin, particularly around the mouth, nose, eyes, and genitals.
- Toxic epidermal necrolysis (TEN), a more severe form that causes extensive peeling of the skin.
- Drug reaction with eosinophilia and systemic symptoms (DRESS), which consists of flu-like symptoms with a rash, fever, swollen lymph nodes, and abnormal blood test results (including an increased number of white blood cells (eosinophilia) and elevated liver enzymes).
- Acute generalized exanthematous pustulosis (AGEP), small pus-filled blisters.
- Erythema multiforme (EM), skin rashes with irregular red patches that itch.
If you develop these symptoms, stop using Seroquel Prolong and contact your doctor or seek medical attention immediately.
