Warnings and cautions

Talk to your doctor or pharmacist before using Quetiapine Sandoz if:

  • you or someone in your family has or has had a heart problem, such as heart rhythm disorders, weak heart muscle or inflammation of the heart, or if you are taking any medications that may affect how your heartbeats.
  • you have low blood pressure.
  • you have had a stroke, especially if you are older.
  • you have liver problems.
  • you have ever had a seizure ( epilepsy ).
  • you have diabetes or are at risk of getting diabetes. Then your doctor may need to measure your blood sugar level when you use Quetiapine Sandoz.
  • you know that you have previously had a low level of white blood cells (which may or may not have been caused by other medicines).
  • you are older and suffering from dementia (a loss of brain function). If this is true for you, do not take Quetiapine Sandoz, as the group of medicines to which Quetiapine Sandoz belongs may increase the risk of stroke, or in some cases the risk of death, in elderly people with dementia.
  • you are older and suffering from Parkinson’s disease/parkinsonism
  • you or someone in your family has had a blood clot, as similar drugs have been linked to the formation of blood clots.
  • you have or have had a condition where you stop breathing for short periods during your normal night’s sleep (called “sleep apnea”) and take drugs that reduce the normal activity of the brain (“sedative”).
  • you have or have had a condition where you can not empty the bladder completely ( urinary retention ), have an enlarged prostate, blockage in the intestines, or increased pressure inside the eye. These conditions are sometimes caused by drugs (called “anticholinergics”) that affect the way nerve cells work to treat certain conditions.
  • you have or have had problems with alcohol or drug abuse.

Tell your doctor immediately if you experience any of the following after taking Quetiapine Sandoz:

  • a combination of fever, severe muscle stiffness, sweating, or decreased consciousness (a condition called malignant neuroleptic syndrome). You may need immediate medical attention.
  • uncontrollable movements, especially in the face or tongue.
  • dizziness or troublesome drowsiness. In older patients, this could increase the risk of accidental injuries (by falling). 
  • seizures. 
  • prolonged and painful erection (priapism).
  • rapid irregular heartbeat even at rest, palpitations, breathing problems, chest pain, or unexplained fatigue. The doctor needs to examine your heart and, if necessary, send (refer) you immediately to a cardiologist.

Such conditions can be caused by this type of drug.

Talk to a doctor as soon as possible if you get:

  • fever, flu-like symptoms, sore throat, or any other infection, as this could be due to a very low white blood cell count, which may require discontinuation of Quetiapine Sandoz and/or treatment for infection.
  • constipation along with persistent pain in the stomach or constipation that does not respond to treatment, as this can lead to a more severe blockage of the intestine.
  • Suicidal thoughts and worsening depression you who are depressed can sometimes have thoughts of wanting to hurt yourself or commit suicide. These symptoms may worsen when you start treatment, as it takes time for a drug of this type to take effect, usually about 2 weeks, but sometimes longer. Thoughts of this type can also increase if you suddenly stop taking your medicine. These thoughts may be more common if you are a young adult. Clinical studies have shown that young adults (younger than 25 years) with depression have an increased risk of suicidal thoughts and/or thoughts of self-harm. Contact a doctor as soon as possible or go to the nearest hospital if you have thoughts of injuring yourself or committing suicide. It can be helpful to tell a relative or close friend that you are depressed. Feel free to ask them to read this leaflet. You can also ask them to tell you if they think the depression is getting worse or if they think your behavior is changing.
