6.Contents of the pack and additional information

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

• Bipolar depression and major depressive episodes in major depressive disorder: for which you may feel sad. You may find that you feel depressed, guilty, lacking in energy, lose your appetite or cannot sleep.
• Mania: you may feel very excited, euphoric, agitated, enthusiastic or hyperactive or display poor judgment which includes being aggressive or violent.
• Schizophrenia: 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 using quetiapine to treat major depressive episodes in major depressive disorder, it will be taken in addition to another medicine that is being used to treat this condition.

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

Do not take Quetiapina Viatris:

-If you are allergic to quetiapine or any of the other components of this medication (listed in section 6).

-If you are taking any of the following medications:

‑Some HIV medications.

‑Azole antifungals (for fungal infections).

‑Erythromycin or clarithromycin (for infections).

‑Nefazodone (for depression).

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

Warnings and precautions

Consult your doctor or pharmacist before starting this medication if:

• You, or a family member, have or have had any heart problems, for example, irregular heart rhythm, heart muscle weakness, or heart inflammation, or are taking any medication that may affect your heart rate.
• You have low blood pressure.
• You have had a stroke, especially if you are an older person.
• You have liver problems.
• You have had a seizure (convulsion).
• You have diabetes or are at risk of developing diabetes. Your doctor may monitor your blood sugar levels while taking quetiapine.
• You have had low white blood cell counts (which may or may not have been caused by other medications).
• You are an older person with dementia (loss of brain function). If so, do not take quetiapine because the group of medications to which quetiapine belongs may increase the risk of stroke or, in some cases, death in older people with dementia.
• You are an older person with Parkinson's disease/parkinsonism.
• You, or a family member, have a history of blood clots, as these types of medications have been associated with blood clot formation.
• You have or have had a condition in which your breathing is interrupted by short periods of time during normal nighttime sleep (called "sleep apnea") and are taking medications that decrease normal brain activity ("depressants").
• You have or have had a condition in which you cannot completely empty your bladder (urinary retention), have an enlarged prostate, intestinal obstruction, or high pressure inside your eye. These conditions may be caused by medications (called "anticholinergics") that affect how nerve cells function, to treat certain medical conditions.
• You have problems with alcohol or drug use.
• You have depression or other conditions treated with antidepressants. The use of these medications with quetiapine may cause serotonin syndrome, a potentially life-threatening condition (see "Other medications and Quetiapina Viatris").

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

• Irregular or rapid heartbeats, even when at rest, palpitations, respiratory problems, chest pain, or unexplained fatigue. Your doctor should examine your heart and, if necessary, refer you to a cardiologist immediately.
• A combination of fever, intense muscle stiffness, sweating, or decreased consciousness (a condition called "neuroleptic malignant syndrome"). Immediate medical treatment may be necessary.
• Uncontrolled movements, mainly of the face or tongue.
• Dizziness or excessive drowsiness. This may increase the risk of accidental injuries (falls) in older adults.
• Seizures (convulsions).
• Prolonged and painful erection (priapism).

These disorders may be caused by this type of medication.

Inform 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 require discontinuation of quetiapine treatment and/or additional treatment.
• Constipation, along with persistent abdominal pain, or constipation that has not responded to treatment, as it may lead to a more serious intestinal obstruction.

Thoughts of suicide and worsening of depression

If you are depressed, you may sometimes think about harming yourself or committing suicide. These thoughts may increase when starting treatment, as all these medications take time to be effective, 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 the 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 can ask them to alert you if they think your depression is worsening 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 medication, which may put your life at risk or be fatal. These typically manifest as:

• Stevens-Johnson syndrome (SSJ), a generalized 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 rash, fever, swollen lymph nodes, and abnormal blood test results (including elevated white blood cell count (eosinophilia) and elevated liver enzymes).
• Generalized 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 this medication and contact your doctor or seek medical attention immediately.
