1. What Quetiapine Krka is and what it is used for

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

• Bipolar depression and major depressive episodes in major depressive disorder: where you feel sad. You may find that you feel depressed, guilty, lack energy, have loss of appetite, or are unable to sleep.
• Mania: where you may feel extremely excited, euphoric, agitated, enthusiastic, or hyperactive, or have poor judgment, which may include being aggressive or violent.
• Schizophrenia: where 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.

When Quetiapine Krka is used to treat major depressive episodes in major depressive disorder, it is taken in addition to another medicine you are already taking for this condition.

Your doctor may continue prescribing Quetiapine Krka even if you feel better.

2. What you need to know before taking Quetiapina Krka

Do not take Quetiapina Krka:

• 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 medicines for HIV

• azole-type medicines (for fungal infections)

• erythromycin or clarithromycin (for infections)

• nefazodone (for depression).

If you have any doubts, consult your doctor or pharmacist before taking this medicine.

Warnings and precautions

Consult your doctor or pharmacist before starting to take Quetiapina Krka if:

• You, or a family member, have or have had any heart problems, for example, heart rhythm disorders, weakening of the heart muscle, heart inflammation, 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 an elderly patient.
• 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 this medicine.
• 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). In this case, you should not take quetiapine, as the group of medicines to which quetiapine belongs may increase the risk of stroke or, in some cases, the risk of death in these patients.
• You are an elderly person with Parkinson's disease/parkinsonism.
• You or a family member have 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 sleep (called “sleep apnea”) and you 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 have 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 Krka”).

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

• 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 necessary.
• Uncontrollable 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).
• Painful and prolonged erection (priapism).
• Rapid or irregular heartbeat, even at rest, palpitations, breathing difficulties, chest pain, or unexplained fatigue. Your doctor should examine your heart and, if necessary, refer you immediately to a cardiologist.

These disorders may be caused by this type of medicine.

Inform 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 low white blood cell count, which may require stopping treatment with quetiapine and/or additional treatment.
• Constipation with persistent abdominal pain, or constipation that has not responded to treatment, as this may lead to a more serious intestinal blockage.

Suicidal thoughts and worsening of your 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. Data from clinical trials have 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 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 behavior.

Serious skin adverse reaction (SSAR)

Serious skin adverse reactions (SSARs), which may be life-threatening or fatal, have very rarely been reported with quetiapine treatment. These have frequently manifested as:

• Stevens-Johnson syndrome (SJS), a widespread rash with blisters and skin peeling, especially around the mouth, nose, eyes, and genitals
• Toxic epidermal necrolysis (TEN), a more severe condition causing extensive skin peeling
• Drug reaction with eosinophilia and systemic symptoms (DRESS), consisting of flu-like symptoms with a rash, fever, swollen glands, and abnormal blood test results (including increased white blood cells (eosinophilia) and liver enzymes)
• Acute generalized exanthematous pustulosis (AGEP), small pustules filled with pus
• Erythema multiforme (EM), a skin rash with irregular red spots that itch

Stop using quetiapine if you develop these symptoms 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 is not used in children and adolescents under 18 years of age.

Other medicines and Quetiapina Krka

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

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

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

Inform your doctor if you are taking any of these 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 levels of potassium or magnesium), such as diuretics (medicines to increase urine production) or certain antibiotics (medicines to treat infections).
• Medicines that may cause constipation.
• Medicines (called “anticholinergics”) that affect how nerve cells function, used to treat certain medical conditions.
• Antidepressants. These medicines may interact with quetiapine and you may experience symptoms such as involuntary rhythmic muscle contractions, including muscles controlling eye movement, agitation, hallucinations, coma, excessive sweating, tremor, exaggerated reflexes, increased muscle tension, 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 Krka with food, drinks, and alcohol

• This medicine may be affected by food; therefore, you should take your tablets at least one hour before a meal or before bedtime.
• Be cautious about the amount of alcohol you consume. This is because the combined effect of this medicine 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 this medicine during pregnancy unless discussed with your doctor. Quetiapine should not be taken if you are breastfeeding.

The following symptoms, which may represent withdrawal syndrome, may occur in newborns of mothers who have used 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, you may need to contact your doctor.

Driving and using machines

Quetiapine may cause symptoms such as drowsiness, dizziness, or vision disturbances, and may reduce reaction ability. These effects, as well as your underlying illness, may impair your ability to drive or operate machinery. Therefore, do not drive, operate machinery, or perform other activities requiring special attention until your doctor has assessed your response to this medicine.

Quetiapina Krka contains lactose and sodium

This medicine contains lactose. If your doctor has informed you of an intolerance to certain sugars, consult with him before taking this medicine.

This medicine contains 14.53 mg of sodium (main component of table/cooking salt) in each 150 mg prolonged-release tablet. This is equivalent to 0.73% of the maximum daily recommended sodium intake for an adult.

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 antidepressant medicines called tricyclic antidepressants (TCAs) when certain analytical methods are used, even if you are not taking methadone or TCAs. If this occurs, a more specific test can be performed.
