Seroquel XR


(quetiapine fumarate) Extended-Release Tablets

Read this Medication Guide before you start taking SEROQUEL XR and each time you get a refill. There may be new information. This Medication Guide does not take the place of talking to your healthcare provider about your medical condition or treatment.

What is the most important information I should know about SEROQUEL XR?

SEROQUEL XR may cause serious side effects, including:

  1. Risk of death in the elderly with dementia
  2. Risk of suicidal thoughts or actions
  3. High blood sugar (hyperglycemia)
  4. High fat levels in your blood (increased cholesterol and triglycerides)
  5. Weight gain

These serious side effects are described below:

  1. Risk of death in the elderly with dementia: Medicines like SEROQUEL XR can increase the risk of death in elderly people who have memory loss (dementia). SEROQUEL XR is not approved for treating psychosis in the elderly with dementia.
  2. Risk of suicidal thoughts or actions (antidepressant medicines, depression and other serious mental illnesses, and suicidal thoughts or actions):

Talk to your, or your family member's, healthcare provider about:

    • all risks and benefits of treatment with antidepressant medicines.
    • all treatment choices for depression or other serious mental illness.
  • Antidepressant medicines may increase suicidal thoughts or actions in some children, teenagers, and young adults within the first few months of treatment.
  • Depression and other serious mental illnesses are the most important causes of suicidal thoughts and actions. Some people may have a particularly high risk of having suicidal thoughts or actions.
    These include people who have (or have a family history of) depression, bipolar illness (also called manic-depressive illness), or suicidal thoughts or actions.

How can I watch for and try to prevent suicidal thoughts and actions in myself or a family member?

  • Pay close attention to any changes, especially sudden changes, in mood, behaviors, thoughts, or feelings. This is very important when an antidepressant medicine is started or when the dose is changed.
  • Call the healthcare provider right away to report new or sudden changes in mood, behavior, thoughts, or feelings.
  • Keep all follow-up visits with the healthcare provider as scheduled. Call the healthcare provider between visits as needed, especially if you have concerns about symptoms.

Call a healthcare provider right away if you or your family member has any of the following symptoms, especially if they are new, worse, or worry you:

  • thoughts about suicide or dying
  • attempts to commit suicide
  • new or worse depression
  • new or worse anxiety
  • feeling very agitated or restless
  • panic attacks
  • trouble sleeping (insomnia)
  • new or worse irritability
  • acting aggressive, being angry, or violent
  • acting on dangerous impulses
  • an extreme increase in activity and talking (mania)
  • other unusual changes in behavior or mood

What else do I need to know about antidepressant medicines?

  • Never stop an antidepressant medicine without first talking to your healthcare provider. Stopping an antidepressant medicine suddenly can cause other symptoms.
  • Antidepressants are medicines used to treat depression and other illnesses. It is important to discuss all the risks of treating depression and also the risks of not treating it. Patients and their families or other caregivers should discuss all treatment choices with the healthcare provider, not just the use of antidepressants.
  • Antidepressant medicines have other side effects. Talk to the healthcare provider about the side effects of the medicine prescribed for you or your family member.
  • Antidepressant medicines can interact with other medicines. Know all of the medicines that you or your family member take. Keep a list of all medicines to show the healthcare provider. Do not start new medicines without first checking with your healthcare provider.
  • Not all antidepressant medicines prescribed for children are FDA approved for use in children. Talk to your child's healthcare provider for more information.

3. High blood sugar (hyperglycemia): High blood sugar can happen if you have diabetes already or if you have never had diabetes. High blood sugar could lead to:

  2. Coma
  3. Death

Increases in blood sugar can happen in some people who take SEROQUEL XR. Extremely high blood sugar can lead to coma or death. If you have diabetes or risk factors for diabetes (such as being overweight or a family history of diabetes) your healthcare provider should check your blood sugar before you start SEROQUEL XR and during therapy.

Call your doctor if you have any of these symptoms of high blood sugar (hyperglycemia) while taking SEROQUEL XR:

  • feel very thirsty
  • need to urinate more than usual
  • feel very hungry
  • feel weak or tired
  • feel sick to your stomach
  • feel confused, or your breath smells fruity.

4. High fat levels in your blood (increased cholesterol and triglycerides): High fat levels may happen in people treated with SEROQUEL XR. You may not have any symptoms, so your doctor may decide to check your cholesterol and triglycerides during your treatment with SEROQUEL XR.

5. Increase in weight (weight gain): Weight gain is common in people who take SEROQUEL XR so you and your doctor should check your weight regularly. Talk to your doctor about ways to control weight gain, such as eating a healthy, balanced diet, and exercising.
