1. What is Symquel XR and what is it used for

Symquel XR contains the active substance quetiapine. It belongs to a group of medicines called antipsychotics. Symquel XR can be used to treat certain diseases, such as:

• depression in bipolar affective disorder or episodes of severe depression in severe depressive disorder, when the patient feels strong sadness or despair, has a sense of guilt, lack of energy and appetite, or cannot sleep.
• mania: when the patient is highly excited, remains in a state of euphoria, is agitated, full of enthusiasm, overactive, or has limited critical judgment, including being aggressive or exhibiting destructive behavior.
• schizophrenia: when the patient hears or feels things that do not exist; believes in things that are not true, or is overly suspicious, anxious, confused, has a sense of guilt, tension, or depression.

If Symquel XR is used to treat episodes of severe depression in severe depressive disorders, the doctor will prescribe another medicine for this condition. If the patient's condition does not improve or worsens, they should contact their doctor.

2. Important information before taking Symquel XR

When not to take Symquel XR

• If the patient is allergic to quetiapine or any of the other ingredients of this medicine (listed in section 6).
• If the patient is taking any of the following medicines:
• certain medicines used to treat HIV infection;
• azole medicines (used to treat fungal infections);
• erythromycin or clarithromycin (used to treat bacterial infections);
• nefazodone (used to treat depression).

If any of the above situations apply to the patient, they should not take Symquel XR. If in doubt, the patient should consult their doctor or pharmacist before taking Symquel XR.

Warnings and precautions

Before starting treatment with Symquel XR, the patient should discuss with their doctor, pharmacist, or nurse if:

• the patient or a family member has or has had any heart problems, such as arrhythmias, weakness, or inflammation of the heart muscle, or if the patient is taking medicines that may affect heart function;
• the patient has low blood pressure;
• the patient has had a stroke in the past, especially if they are elderly;
• the patient has liver function disorders;
• the patient has had seizures (epilepsy);
• the patient has ever had a low white blood cell count (regardless of whether it was caused by taking other medicines or not);
• the patient has diabetes or is at risk of developing diabetes, in which case the doctor may order a blood sugar test while taking Symquel XR;
• the patient or a family member has had blood clots, as the use of medicines like this one is associated with the formation of clots;
• the patient is elderly with dementia (age-related cognitive impairment). Such a person should not take Symquel XR, as medicines in the same class as Symquel XR may increase the risk of stroke and, in some cases, the risk of death in elderly patients with dementia;
• the patient is elderly and has Parkinson's disease/parkinsonism;
• the patient has or has had a condition characterized by short pauses in breathing during normal sleep at night (so-called sleep apnea) and is taking medicines that slow down brain function (so-called depressants);
• the patient has or has had a condition characterized by inability to completely empty the bladder (urinary retention), has an enlarged prostate, intestinal obstruction, or increased eye pressure. These symptoms may be caused by medicines (so-called anticholinergic medicines) that affect the function of nerve cells and are used to treat certain diseases;
• the patient has or has had problems with alcohol or drug abuse;
• if the patient has depression or other conditions that are treated with antidepressant medicines. The use of these medicines with Symquel XR may lead to the development of a potentially life-threatening condition called serotonin syndrome (see "Symquel XR and other medicines").

The patient should immediately inform their doctor if they experience symptoms such as:

• fever with muscle stiffness, excessive sweating, or decreased level of consciousness (a condition called malignant neuroleptic syndrome). Immediate medical attention may be necessary;
• involuntary movements, especially of the face or tongue;
• dizziness or a feeling of extreme drowsiness. This may increase the risk of injury (falls) in elderly patients;
• seizures;
• prolonged and painful erection (priapism);
• rapid and irregular heartbeat, even at rest, palpitations, difficulty breathing, chest pain, or unexplained fatigue. The doctor will need to examine the heart and, if necessary, immediately refer the patient to a cardiologist.

All these symptoms may occur during treatment with medicines in this therapeutic class. The patient should inform their doctor as soon as possible if they experience:

• fever, flu-like symptoms, sore throat, or any other infection, as these may be caused by a very low white blood cell count, which may require discontinuation of Symquel XR and/or initiation of appropriate treatment.
• constipation with persistent abdominal pain or constipation that does not improve with treatment, as this may lead to severe intestinal obstruction.

Suicidal thoughts or worsening depression

Patients with depression may sometimes think about self-harm or suicide. This happens especially at the beginning of treatment with antidepressant medicines, as these medicines usually start working only after 2 weeks, sometimes later. Suicidal thoughts may worsen in patients who suddenly stop taking their medicines. The likelihood of such thoughts is higher in young adults. Clinical trials have shown an increased risk of suicidal thoughts and/or behaviors in young patients under 25 years of age with depression. If the patient experiences thoughts of self-harm or suicidal thoughts, they should immediately contact their doctor or go to the hospital. It may be helpful to inform friends and relatives about the depression and its symptoms and ask them to read this leaflet and inform the patient if they notice that the depression has worsened or if there are worrying changes in the patient's behavior. Severe skin reactions(SCAR) have been very rarely reported during treatment with Symquel XR, which can be life-threatening or lead to death. They usually manifest as:

• Stevens-Johnson syndrome (SJS), a widespread rash with blisters and peeling skin, especially around the mouth, nose, eyes, and genitals;
• Toxic Epidermal Necrolysis (TEN), a more severe form causing widespread peeling of the skin;
• Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS); a rash with flu-like symptoms, fever, swollen lymph nodes, and abnormal blood test results (including increased white blood cell count (eosinophilia) and liver enzymes);
• Acute Generalized Exanthematous Pustulosis (AGEP) - small blisters filled with pus
• Erythema Multiforme (EM) - a skin rash with irregular, itchy, red patches

If the patient experiences these symptoms, they should stop taking Symquel XR and immediately contact their doctor or seek medical attention.

Weight gain

Patients taking Symquel XR have experienced weight gain. The patient should regularly check their weight, either alone or with their doctor.

Children and adolescents

Symquel XR is not intended for use in children and adolescents under 18 years of age.

Symquel XR and other medicines

The patient should tell their doctor about all medicines they are currently taking or have recently taken, as well as any medicines they plan to take. The patient should not take Symquel XR if they are taking any of the following medicines:

• certain medicines used to treat HIV;
• azole medicines (used to treat fungal infections);
• erythromycin or clarithromycin (used to treat bacterial infections);
• nefazodone (used to treat depression).

The patient should tell their doctor if they are taking any of the following medicines:

• antiepileptic medicines (such as phenytoin or carbamazepine);
• antihypertensive medicines;
• barbiturates (medicines used to treat sleep disorders);
• thioridazine or lithium (other antipsychotic medicines);
• medicines that affect heart rhythm, such as medicines that cause electrolyte disturbances (decreasing potassium or magnesium levels), such as diuretics (medicines that increase urine production) or certain antibiotics;
• medicines that may cause constipation;
• medicines used to treat certain diseases that affect the function of nerve cells (so-called anticholinergic medicines);
• antidepressant medicines. These medicines may interact with Symquel XR and may cause symptoms such as involuntary, rhythmic muscle contractions, including eye movements, agitation, hallucinations, coma, excessive sweating, tremors, increased reflexes, muscle tension, and body temperature above 38°C (serotonin syndrome). If such symptoms occur, the patient should consult their doctor.

The patient should not stop taking other medicines without consulting their doctor or pharmacist.

Symquel XR with food, drink, and alcohol

• Taking food may affect the action of the medicine, so Symquel XR should be taken at least 1 hour before a meal or before bedtime.
• The patient should be careful with the amount of alcohol they consume. Taking Symquel XR and alcohol at the same time may cause drowsiness.
• While taking Symquel XR, the patient should not drink grapefruit juice, as it may affect the action of the medicine.

Pregnancy, breastfeeding, and fertility

If the patient is pregnant or breastfeeding, thinks they may be pregnant, or plans to have a child, they should consult their doctor or pharmacist before taking this medicine. The patient should not take Symquel XR during pregnancy, unless it has been agreed with their doctor. Symquel XR should not be used during breastfeeding. In newborns whose mothers took Symquel XR during the last trimester of pregnancy (during the last three months of pregnancy), the following symptoms may occur, which may be symptoms of withdrawal: tremors, stiffness, and/or muscle weakness, drowsiness, agitation, breathing difficulties, feeding difficulties. If the child experiences any of these symptoms, the patient should contact their doctor.

Driving and using machines

This medicine may cause drowsiness. The patient should not drive or operate machinery until they know how they react to the medicine.

Symquel XR contains lactose monohydrate

Symquel XR contains lactose monohydrate, a type of sugar. If the patient has been diagnosed with intolerance to some sugars, they should consult their doctor before taking the medicine.

Symquel XR contains sodium

Symquel XR contains less than 1 mmol (23 mg) of sodium per tablet, which means the medicine is considered "sodium-free".

Effect on urine tests for drug detection

In patients taking Symquel XR, urine tests for drug detection performed by some methods may show the presence of methadone or certain antidepressant medicines called tricyclic antidepressants (TCAs), even if the patient is not taking these medicines. It is recommended to perform these tests using other methods to confirm the results.
