Your doctor may continue prescribing Seroquel Prolong even when you are feeling better.

-Nefazodone (for depression).

If you are unsure, 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, for example, irregular heart rhythm, weakening of the heart muscle or inflammation of the heart, or if you are taking any medicine 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. Your doctor may monitor your blood sugar levels while you are taking Seroquel Prolong.
• if you know that you have had low white blood cell counts (which may or may not have been caused by other medicines).
• if you are an elderly person with dementia (loss of brain function). If so, do not take Seroquel Prolong because the group of medicines to which Seroquel Prolong belongs may increase the risk of stroke or, in some cases, death in these people.
• if you are an elderly person with Parkinson's disease/parkinsonism.
• if you or a family member has a history of blood clots, as medicines like these 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 of time during normal sleep (called "sleep apnoea") and are taking medicines that decrease normal brain activity ("depressants").
• if you have or have had a condition in which you cannot completely empty your bladder (urinary retention), have an enlarged prostate, a bowel obstruction or high pressure inside your eye. These conditions may be caused by medicines (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 with Seroquel Prolong may cause serotonin syndrome, a potentially life-threatening condition (see "Other medicines and Seroquel Prolong").

Inform your doctor immediately if after taking Seroquel Prolong you experience any of the following::

• A combination of fever, intense muscle stiffness, sweating or a decrease in consciousness (a condition called "neuroleptic malignant syndrome"). You may need immediate medical treatment.
• Uncontrolled movements, mainly of your face or tongue.
• Dizziness or feeling very drowsy. This may increase the risk of accidental injuries (falls) in elderly patients.
• Seizures (convulsions).

• A prolonged and painful erection (priapism).
• Fast and irregular heartbeats, even when at rest, palpitations, breathing problems, chest pain or unexplained fatigue. Your doctor will examine your heart and, if necessary, refer you to a cardiologist immediately.

These conditions may be caused by this type of medicine.

Inform your doctor as soon as possible if you have:

• Fever, symptoms similar to the flu, sore throat, or any other infection, as it may be a consequence of a very low white blood cell count and require discontinuation of Seroquel Prolong treatment and/or additional treatment.
• Constipation with persistent abdominal pain, or constipation that has not responded to treatment, as it may lead to a more severe bowel obstruction.
• Thoughts of suicide and worsening of depression

If you are depressed, you may sometimes think about harming yourself or committing suicide. This may increase at the beginning of treatment, as all these medicines take time to take effect, usually around two weeks but sometimes longer. These thoughts may also increase if you stop taking your medication abruptly. You may be more likely to think this way if you are a young adult. Information from clinical trials has shown an increased risk of thoughts of suicide and/or suicidal behavior in young adults under 25 with depression.

If you ever think about harming yourself or committing suicide, contact your doctor or go to a hospital immediately. It may help to tell a close family member or friend that you are depressed, and ask them to read this leaflet. You may ask them to tell you if they think your depression is getting worse, or if they are concerned about changes in your behavior.

Severe skin reactions (SCARs)

Very rarely, severe skin reactions (SCARs) have been reported with the use of this medicine, which may put your life at risk or be fatal. These usually manifest as:

• Stevens-Johnson syndrome (SSJ), a generalised rash with blisters and skin peeling, particularly around the mouth, nose, eyes and genitals.
• Toxic epidermal necrolysis (NET), a more severe form that causes extensive skin peeling.

• 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 increased white blood cell count (eosinophilia) and elevated liver enzymes).
• Generalised Acute 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.
