1. What Quetiapina Sandoz Farmacéutica is and what it is used for

Quetiapina Sandoz Farmacéutica contains a substance called quetiapine. It belongs to a group of medicines known as antipsychotics. Quetiapine can 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, lack energy, lose your appetite, or are unable to sleep.
• Mania: for which you may feel highly excited, euphoric, agitated, enthusiastic, or hyperactive, or have poor judgment, which may include aggressive or violent behavior.
• Schizophrenia: for 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.

When quetiapine is used to treat major depressive episodes in major depressive disorder, it is taken in addition to another medicine you are already using to treat this condition.

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

2. What you need to know before taking Quetiapine Sandoz Farmacéutica

Do not take Quetiapine Sandoz Farmacéutica

• 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:

• some 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 quetiapine.

Warnings and precautions

Talk to your doctor or pharmacist before starting Quetiapine Sandoz Farmacéutica if:

• you, or a family member, have or have had any heart problems, for example, heart rhythm problems, 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 (convulsion),
• 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 functions). If so, you should not take quetiapine because the group of medicines to which quetiapine belongs may increase the risk of stroke, or in some cases the risk of death, in these people,
• 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 nighttime 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 completely empty your bladder (urinary retention), have an enlarged prostate, a bowel 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, or if you have depression or other conditions treated with antidepressants. Using these medicines together with Quetiapine Sandoz Farmacéutica may cause serotonin syndrome, a potentially life-threatening condition (see “Other medicines and Quetiapine Sandoz Farmacéutica”).

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

• a combination of fever, severe muscle stiffness, sweating, or decreased level of consciousness (a disorder called “neuroleptic malignant syndrome”). Immediate medical treatment may be necessary,
• uncontrollable movements, mainly of your face or tongue,
• dizziness or feel very sleepy. This may increase the risk of accidental injuries (falls) in elderly patients,
• seizures (convulsions),
• a prolonged and painful erection (priapism),
• rapid or irregular heartbeats, even at rest, palpitations, breathing problems, chest pain, or unexplained tiredness. 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 very low count of white blood cells and may require discontinuation of quetiapine treatment 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 your 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 work, usually about two weeks but sometimes longer. These thoughts may also increase if you suddenly stop taking your medication. 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 thoughts and/or suicidal behaviour 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 let you know 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 the use of this medicine. These commonly manifest as:

• Stevens-Johnson syndrome (SJS), a widespread rash with blisters and skin peeling, 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 cell count (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 using Quetiapine Sandoz Farmacéutica and contact your doctor or seek immediate medical attention.

• Some medicines for HIV.
• Azole-type medicines (for fungal infections).

Contact your doctor if you experience these symptoms.

Taking Quetiapine Sandoz Farmacéutica with food, drinks, and alcohol

• Quetiapine may be affected by food, and 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 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 before using this medicine. You should not take quetiapine during pregnancy unless advised by your doctor. You should not use quetiapine if you are breastfeeding.

The following symptoms, which may represent a withdrawal syndrome, may occur in newborns whose mothers have used quetiapine during the third trimester (last three months of pregnancy): tremor, muscle rigidity 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

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

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 testing methods are used, even if you are not taking methadone or TCAs. If this occurs, a more specific test can be performed.
