1. What Quetiapina Viatris is and what it is used for

Quetiapina Viatris contains a substance called quetiapine. It belongs to a group of medicines known as antipsychotics. Quetiapine may be used to treat several conditions, such as:

• Bipolar depression: a condition in which you feel sad. You may find that you feel depressed, guilty, lack energy, lose your appetite, or are unable to sleep.
• Mania: a condition in which you may feel extremely excited, euphoric, restless, enthusiastic, or hyperactive, or have poor judgment, which may include being aggressive or violent.
• Schizophrenia: a condition in which you may hear or sense things that are not there, believe things that are not true, or feel abnormally suspicious, anxious, confused, guilty, tense, or depressed.

Your doctor may continue to prescribe quetiapine for you even after you are feeling better.

2. What you need to know before taking Quetiapina Viatris

Do not take Quetiapina Viatris:

• 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:

• Certain HIV medications.

• Azole-type medicines (for fungal infections).

• Erythromycin or clarithromycin (for infections).

• Nefazodone (for depression).

Do not take quetiapine if any of the above apply to you. If you are in any doubt, consult your doctor or pharmacist before taking quetiapine.

Warnings and precautions

Talk to your doctor or pharmacist before starting quetiapine if:

• You, or a family member, have or have had heart problems, for example, heart rhythm disorders, weakening of the heart muscle, or inflammation of the heart, or if you are taking any medicine that may affect your heartbeat.
• You have low blood pressure.
• You have had a stroke, especially if you are elderly.
• You have liver problems.
• You have ever had a seizure (epileptic fit).
• You have diabetes or are at risk of developing diabetes. If so, your doctor may monitor your blood sugar levels while you are taking quetiapine.
• You know you have previously had low levels of white blood cells (which may or may not have been caused by other medicines).
• You are an elderly person with dementia (loss of brain function). If so, you should not take quetiapine, as the group of medicines to which this belongs may increase the risk of stroke or, in some cases, risk of death in elderly patients with dementia.
• You are an elderly person with Parkinson’s disease/parkinsonism.
• You or a family member has a history of blood clots, as medicines like this have been associated with blood clot formation.
• You have or have had a condition in which your breathing stops for short periods during normal nighttime sleep (called “sleep apnea”) and are taking medicines that reduce normal brain activity (“depressants”).
• You have or have had a condition in which you cannot fully empty your bladder (urinary retention), have an enlarged prostate, intestinal obstruction, or increased pressure inside your eye. These conditions can sometimes be caused by medicines (called “anticholinergics”) that affect how nerve cells function, used to treat certain medical conditions.
• You have a history of alcohol or drug abuse.
• You suffer from depression or other conditions treated with antidepressants. The use of these medicines together with quetiapine may cause serotonin syndrome, a potentially life-threatening condition (see “Other medicines and Quetiapina Viatris”).

Tell your doctor immediately if, after taking quetiapine, you experience any of the following:

• Fast or irregular heartbeat, even at rest, palpitations, breathing difficulties, chest pain, or unexplained tiredness. Your doctor should examine your heart and, if necessary, refer you immediately to a cardiologist.
• A combination of fever, severe muscle stiffness, sweating, or decreased level of consciousness (a disorder known as “neuroleptic malignant syndrome”). Immediate medical treatment may be required.
• Uncontrolled movements, mainly of your face or tongue.
• Dizziness or excessive drowsiness. This may increase the risk of accidental injuries (falls) in elderly patients.
• Seizures (epileptic fits).
• A prolonged and painful erection (priapism).

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 this could be due to a very low count of white blood cells and may require stopping quetiapine and/or additional treatment.
• Constipation along with persistent abdominal pain or constipation that has not responded to treatment, as this could lead to a more serious intestinal blockage.

Suicidal thoughts and worsening of depression

If you are depressed, you may sometimes think about harming yourself or committing suicide. This risk may increase at the beginning of treatment, as all these medicines take time to work—usually about two weeks, but sometimes longer. These thoughts may also increase if you stop your medication abruptly. You may be more likely to have such thoughts if you are a young adult. Clinical trial data have shown an increased risk of suicidal behaviour and/or thoughts in young adults under 25 years of age with depression.

If you have ever had thoughts of 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 inform you if they think your depression is getting worse or if they are concerned about changes in your behaviour.

Serious skin adverse reactions (SCARs)

Very rarely, serious skin adverse reactions (SCARs), which may be life-threatening or fatal, have been reported with this medicine. These commonly manifest as:

• Stevens-Johnson syndrome (SJS), a widespread rash with blistering and peeling of the skin, particularly around the mouth, nose, eyes, and genitals.
• Toxic epidermal necrolysis (TEN), a more severe form causing extensive skin peeling.
• Drug reaction with eosinophilia and systemic symptoms (DRESS), characterized by flu-like symptoms with rash, fever, swollen lymph nodes, and abnormal blood test results (including increased white blood cells (eosinophilia) and elevated liver enzymes).
• Acute generalized exanthematous pustulosis (AGEP), small pustules filled with pus.
• Erythema multiforme (EM), skin rashes with itchy, irregular red spots.

If you develop any of these symptoms, stop taking quetiapine and contact your doctor or seek immediate medical attention.

Weight gain

Weight gain has been observed in patients taking quetiapine. You and your doctor should monitor your weight regularly.

Children and adolescents

Quetiapine must not be used in children and adolescents under 18 years of age.

Other medicines and Quetiapina Viatris

Tell your doctor or pharmacist if you are taking, have recently taken, or might need to take any other medicines.

Do not take quetiapine if you are using any of the following medicines:

• Certain HIV medications.
• Azole-type medicines (for fungal infections).
• Erythromycin or clarithromycin (for infections).
• Nefazodone (for depression).

Consult your doctor if you are taking any of the following medicines:

• Medicines for epilepsy (such as phenytoin or carbamazepine).
• Medicines for high blood pressure.
• Barbiturates (for difficulty sleeping).
• Thioridazine or lithium (other antipsychotic medicines).
• Medicines that affect your heartbeat, for example, medicines that may cause an electrolyte imbalance (low potassium or magnesium levels), such as diuretics (medicines to increase urine production) or certain antibiotics (medicines to treat infections).
• Medicines that may cause constipation.
• Antidepressants. These medicines may interact with quetiapine, and you may experience symptoms such as involuntary, rhythmic muscle contractions (including eye movement control muscles), agitation, hallucinations, coma, excessive sweating, tremor, exaggerated reflexes, increased muscle tone, and body temperature above 38 °C (serotonin syndrome). Contact your doctor if you experience these symptoms.

Before stopping any of your medicines, consult your doctor first.

Taking Quetiapina Viatris with food, drinks, and alcohol

Be cautious about the amount of alcohol you consume. This is because the combined effect of quetiapine and alcohol may make you drowsy.

Do not drink grapefruit juice while taking quetiapine. It may affect how the medicine works.

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor or pharmacist before using this medicine. You should not take quetiapine during pregnancy unless advised by your doctor. You should not use quetiapine while breastfeeding.

The following symptoms, which may represent a withdrawal syndrome, may occur in newborns whose mothers have taken quetiapine during the third trimester (last three months of pregnancy): tremor, muscle stiffness and/or weakness, drowsiness, agitation, breathing difficulties, and feeding problems. If your newborn develops any of these symptoms, contact your doctor.

Driving and using machines

These tablets may make you feel drowsy. Do not drive or operate tools or machinery until you know how these tablets affect you.

Quetiapina Viatris contains lactose and sodium

Quetiapina Viatris contains lactose, a type of sugar. If your doctor has told you that you have an intolerance to certain sugars, consult him before taking this medicine.

This medicine contains less than 1 mmol of sodium (23 mg) per tablet; thus, it is essentially “sodium-free”.

Effect on urine drug screening tests

If you are undergoing a urine drug screening test, taking quetiapine may produce positive results for methadone or certain antidepressants known as tricyclic antidepressants (TCAs) when certain testing methods are used, even if you are not taking methadone or TCAs. If this occurs, a more specific test can be performed.

3. How to take Quetiapine Viatris

Follow exactly the instructions for use of this medicine as given by your doctor. If in doubt, consult your doctor or pharmacist again.

Your doctor will determine your initial dose. The maintenance dose (daily dose) will depend on your condition and individual needs, but will usually be between 150 mg and 800 mg.

• You will take your tablets once daily at bedtime or twice daily, depending on your condition.
• Swallow your tablets whole with water. You may take the tablets with or without food. Do not drink grapefruit juice while taking quetiapine. It may affect how the medicine works.
• Do not stop taking your tablets even if you feel better, unless your doctor tells you to.

Liver problems

If you have liver problems, your doctor may adjust your dose.

Elderly patients

If you are an elderly patient, your doctor may adjust your dose.

Use in children and adolescents

Quetiapine must not be used in children and adolescents under 18 years of age.

If you take more Quetiapine Viatris than you should

If you take more quetiapine than prescribed by your doctor, you may feel drowsy, dizzy, and experience abnormal heartbeats, dry mouth, constipation, dilated pupils, or blurred vision. Contact your doctor or nearest hospital immediately. Take the packaging and any remaining tablets with you.

You may also call the Toxicology Information Service at telephone number 915620420, stating the medicine and the amount taken.

If you forget to take a dose of Quetiapine Viatris

If you forget to take a dose, take it as soon as you remember. If it is almost time for your next dose, wait until then. Do not take a double dose to make up for the forgotten tablet.

If you stop taking Quetiapine Viatris

If you stop taking quetiapine abruptly, you may have difficulty sleeping (insomnia), feel nauseous, or experience headache, diarrhoea, vomiting, dizziness, or irritability. Your doctor may advise you to gradually reduce the dose before stopping treatment.

If you have any further questions about the use of this medicine, ask your doctor or pharmacist.

4. Possible adverse effects

Like all medicines, this medicine can cause adverse effects, although not everyone experiences them.

Contact a doctor IMMEDIATELY if you develop any of the following adverse effects:

Very common (may affect more than 1 in 10 people):

• Seizures or convulsions.
• Allergic reactions which may include skin lumps (papules), skin swelling, and swelling around the mouth.
• Uncontrollable movements, mainly of the face or tongue.
• Changes detected on ECG in the heart's electrical activity (prolongation of the QT interval) which may cause a very rapid heartbeat and fainting, and may lead to serious heart problems.
• Difficulty urinating.
• Worsening of pre-existing diabetes.

Rare (may affect up to 1 in 1,000 people):

• A combination of high temperature (fever), sweating, muscle stiffness, extreme drowsiness or fainting, and marked increase in blood pressure or heart rate (a disorder known as "neuroleptic malignant syndrome").

• Yellowing of the skin and eyes (jaundice).
• Inflammation of the liver (hepatitis).
• Prolonged and painful erection (priapism).
• Blood clots in the veins, especially in the legs (symptoms include swelling, pain, and redness in the leg), which could travel through the blood vessels to the lungs, causing chest pain and difficulty breathing.
• A combination of fever, flu-like symptoms, sore throat, or any other infection with a very low white blood cell count, a condition known as agranulocytosis.
