What the medication is used for
Sandoz Quetiapine (quetiapine fumarate immediate-release) (pronounced KETIAPIN) is used to:
- Treat the symptoms of schizophrenia, such as hallucinations (hearing or seeing things which are not there), fixed false beliefs, unusual suspiciousness, or emotional withdrawal. Patients may also feel depressed, anxious or tense.
- Treat the symptoms of mania associated with bipolar disorder, such as racing thoughts, irritability, aggressiveness, agitation, impulsive behaviour or excessively elevated mood.
- Treat the symptoms of depression associated with bipolar disorder, such as sadness, feeling guilty, lack of energy, loss of appetite and/or sleep disturbance.
You may find it helpful to tell a friend or relative that you are suffering from these symptoms, and ask them to read this leaflet. You might ask them to tell you if they think your symptoms are getting worse, or if they are worried about any other changes in your behaviour.
Your doctor may have prescribed Sandoz Quetiapine for another reason. Ask your doctor if you have any questions about why Sandoz Quetiapine has been prescribed for you.
Sandoz Quetiapine is not a cure for your condition but it can help manage your symptoms and help you feel better.
What it does
Sandoz Quetiapine is a medication that belongs to a class of medicines called "atypical antipsychotics".
Illnesses that affect the brain, such as schizophrenia and bipolar disorder, may be due to certain chemicals in the brain being out of balance. These imbalances may cause some of the symptoms you may be experiencing. Doctors and scientists are not sure what causes these imbalances to occur. Sandoz Quetiapine is thought to work by regulating the imbalance of chemicals in the brain.

Warnings and precautions
Serious Warnings and Precautions
Studies with various medications of the group to which quetiapine fumarate belongs, including quetiapine fumarate, when used in elderly patients with dementia have been associated with an increased rate of death. Sandoz Quetiapine is not indicated in elderly patients with dementia.
Before starting Sandoz Quetiapine, be sure to tell your doctor:
- If you have had an allergic reaction to any medicine which you have taken previously to treat your condition, or if you think you might be sensitive or allergic to any of the ingredients in Sandoz Quetiapine.
- About any other medications - prescription, nonprescription or alternative - that you are taking or plan to take. Certain medications can seriously affect the way other medications work.
- If you are pregnant or plan to become pregnant while taking Sandoz Quetiapine.
- If you are breast-feeding or are planning on breastfeeding while taking Sandoz Quetiapine. You should not breast-feed while taking Sandoz Quetiapine.
- If you drink alcohol or use street drugs.
- If you have a history of alcohol or drug abuse.
- If you have any health problems.
- If you have low or high blood pressure or have had a stroke.
- If you or a family member have a history of any problems with the way your heart beats or have a history of heart disease or heart problems or if you are taking any medicines that may have an impact on the way your heart beats.
- If you have a history of seizures (fit).
- If you have diabetes, a family history of diabetes or high blood sugar during pregnancy.
- If you have a history of liver or kidney problems.
- If you know that you had a low white blood cell count in the past which may or may not have been caused by other medicines.
- If you exercise vigorously or work in hot or sunny places.
- If you have risk factors for developing blood clots such as: a family history of blood clots, age over 65, smoking, obesity, recent major surgery (such as hip or knee replacement), immobility due to air travel or other reason, or take oral contraceptives (“The Pill”).
- If you suffer or have ever suffered from severe constipation, obstruction of the bowel or any other condition which has affected your large bowel.
- If you have or have had a condition where you stop breathing for short periods during your normal nightly sleep (called “sleep apnea”) and are taking medicines that slow down normal activity of the brain (“depressants”) or breathing.
- If you have or have had a condition where your bladder does not empty or does not empty completely (urinary retention), have an enlarged prostate, a blockage in your intestines, or increased pressure inside your eyes. These conditions are sometimes caused by medicines called “anticholinergics”.
Tell your doctor as soon as possible if you have:
- Fever, flu-like symptoms, sore throat, or any other infection, as this could be a result of a very low white blood cell count, which may require Sandoz Quetiapine to be stopped and/or treatment to be given.
- Constipation along with persistent stomach pain, or constipation which has not responded to treatment, as this may lead to a more serious blockage of the bowel.
In clinical studies with quetiapine fumarate and other drugs of this type, an increased risk of death has been reported in elderly patients with dementia and behavioral disturbances. Sandoz Quetiapine is not approved for this use.
Pancreatitis (inflammation of the pancreas) has been reported in some patients. Many of these patients also had factors which are known to be associated with pancreatitis such as increased triglyceride (a fatty substance in the blood) levels, gallstones and alcohol consumption.
Cardiomyopathy (weakening of the heart muscle) and myocarditis (inflammation of the heart) have been reported in some patients, however, it is not known if Sandoz Quetiapine treatment is related to these problems.
If you already have diabetes, you should be monitored for worsening of your diabetes.
Do not drive or operate machinery until you know your response to this medication, as Sandoz Quetiapine can cause drowsiness.
Thoughts of suicide and worsening of your depression or other mental illnesses
If you are depressed and/or have other mental illnesses, you may sometimes have thoughts of harming or killing yourself. These may be increased when first starting treatment, since these medicines all take time to work, usually about two weeks but sometimes longer.
If you have thoughts of harming or killing yourself at any time, contact your doctor or go to a hospital straight away.
You may find it helpful to tell a relative or close friend that you are depressed or have other mental illnesses, and ask them to read this leaflet. You might ask them to tell you if they think your depression or mental illness is getting worse, or if they are worried about changes in your behaviour.
Severe cutaneous adverse reactions (SCARs)
Serious skin rashes, which can be life-threatening, have occurred
with the use of quetiapine fumerate. Symptoms include
blistering, peeling of the lips, eyes, mouth or genitals, swelling
of the face and/or tongue, and hives. These serious skin rashes
may progress to widespread blistering or peeling of the skin and
are often accompanied by flu-like symptoms, blood
abnormalities (increase in a type of white blood cells sometimes
seen in allergic reactions) and swollen glands (enlarged lymph
nodes).
Stop using Sandoz Quetiapine if you develop these symptoms and contact your doctor or seek medical attention immediately.
Effects on Newborns
In some cases, babies born to a mother taking quetiapine fumarate during pregnancy have experienced symptoms of withdrawal that are severe and require the newborn to be hospitalized. Sometimes, the symptoms may resolve on their own. Be prepared to seek immediate emergency medical attention for your newborn if they have difficulty breathing, are overly sleepy, have muscle stiffness, or floppy muscles (like a ragdoll), are shaking, or are having difficulty feeding.
Interactions with this medication
Because certain medications can seriously affect the way other medications work, it is important to tell all doctors, dentists, and pharmacists who are treating you that you are taking Sandoz Quetiapine.

Dopamine agonists, e.g., levodopa (antiparkinsonian agent), may decrease the effect of Sandoz Quetiapine.
Medications known to interact with Sandoz Quetiapine include carbamazepine (anticonvulsant), phenytoin (anticonvulsant), ketoconazole (antifungal), and protease inhibitors (for treating Human Immunodeficiency Virus).
You should tell your doctor if you are taking erythromycin (antibiotic), clarithromycin (antibiotic), nefazodone, thioridazine (antipsychotic), diltiazem or verapamil (blood pressure medications), medications that can cause constipation or medicines called “anticholinergics” that may affect your ability to empty your bladder. You should also tell your doctor if you are taking medicines that have an impact on the way and how slow your heart beats, for ex., drugs that can cause an imbalance in electrolytes (low levels of potassium or magnesium) such as diuretics (water pills) or certain antibiotics (drugs to treat infections).

- Have a family member or friend remind you to take your medication.
Side effects and what to do about them
Like any medication, Sandoz Quetiapine may produce side effects in some people.
Increases in blood glucose (sugar) and hyperglycemia (high blood sugar) have been observed with quetiapine fumarate. Also, occasional cases of diabetes have been reported. Your doctor may take blood tests to check your blood sugar before starting Sandoz Quetiapine. They may continue to monitor your blood sugar for as long as you are being treated. Light-headedness and dizziness (symptoms of postural hypotension) and drowsiness are among the most common side effects you may experience while taking Sandoz Quetiapine, particularly during the first week of treatment or after an increase in dose. The dizziness and drowsiness are usually mild and should go away with time. To help prevent these feelings, be careful to move slowly when you are getting up from a sitting or lying position. Dizziness and drowsiness may lead to falls.
Low blood pressure in standing position is common, which may result in dizziness or feeling faint (may lead to falls).
As feelings of drowsiness are also common at the start of treatment, or when your dose is increased, if you have to drive, operate machinery or do anything else that requires you to be fully alert, use extra caution until you are sure Sandoz Quetiapine does not cause you to be drowsy.
Dry mouth and weight gain have also been reported very commonly in patients taking quetiapine fumarate. Your doctor may take your body weight before starting Sandoz Quetiapine and continue to monitor it for as long as you are being treated.
Discontinuation symptoms which occur upon stopping quetiapine fumarate have been reported very commonly and include insomnia (inability to sleep), nausea, headache, diarrhea, vomiting, dizziness, and irritability. Gradual withdrawal over a period of at least one to 2 weeks is advisable.
Other common side effects may include: headache, rapid heartbeat, feeling like your heart is pounding, racing or has skipped beats, shortness of breath, constipation, indigestion, feeling weak, swelling of arms and legs, fever, upset stomach or abdominal pain, vomiting (mainly in the elderly), blurred vision, abnormal dreams and nightmares, irritability, feeling more hungry, disturbance in speech and language, and changes in laboratory tests for liver and thyroid functions.
There have been uncommon cases of difficulty swallowing, fainting (may lead to falls), stuffy nose, difficulty in passing urine, and a slower than normal heart rate which may occur when starting treatment and which may be associated with low blood pressure and fainting.
There have also been reports, in a small number of patients, of changes to the lens of the eye. Although it is not known whether or not these changes are caused by Sandoz Quetiapine, your doctor may advise you that a specific type of eye exam is recommended in order to maximize safe use of this drug.
In rare cases, there have been reports of decreased body temperature (hypothermia), a combination of fever, flu-like symptoms, sore throat, or any other infection with very low white blood cell count (a condition called agranulocytosis), bowel obstruction, and walking, talking, eating or other activities while asleep.
In very rare cases, this type of medicine can interfere with your body's ability to control body temperature. Therefore, take care to avoid becoming overheated or dehydrated (for ex., with vigorous exercise, or exposure to extreme heat) while taking Sandoz Quetiapine.
Side effects that are of unknown frequency (cannot be estimated from available data) include symptoms of withdrawal in newborn babies of mothers that have used Sandoz Quetiapine during their pregnancy.
The following may also occur with Sandoz Quetiapine and may be seen in routine blood testing:
- Decrease in the amount of white blood cells. These changes will normally disappear when stopping the treatment of Sandoz Quetiapine.
- Decrease in the amount of red blood cells. These are the cells that transport oxygen throughout the body.
- Increase in the amount of eosinophils. These are a type of white blood cell sometimes seen in allergic reactions.
- Decrease in platelets (thrombocytopenia), which are cells that help you stop bleeding if you get a cut.
- Increase in the amount of liver enzymes. These changes will normally disappear when continuing the treatment of Sandoz Quetiapine.
- Changes in the amount of fatty substances (lipid levels, such as triglycerides and cholesterol) in the blood.
- Increase in the amount of ‘creatine phosphokinase’, a substance in the muscles.
- Increase in the amount of sugar (glucose) in the blood.
- Increase in the amount of hormone prolactin in the blood. Rarely (< 0.1% - ≥ 0.01%) this may lead to swelling of breasts and unexpected production of breast milk in women and in some men, and changes in the regularity of monthly period.
- If you have high levels of prolactin and a condition called hypogonadism you may be at increased risk of breaking a bone due to osteoporosis. This may occur in both men and women
