Symptoms of schizophrenia

According to the DSM-5,* a medical reference commonly used by health care professionals to aid in diagnosis, the symptoms of schizophrenia include:

  • Experiencing delusions (believing in things that are not true)
  • Having hallucinations (seeing things that are not there or hearing voices in your head)
  • Disorganized speech (talking but not making sense)
  • Extremely disorganized behavior (eg, like wearing layers of winter clothing on a summer's day; disheveled appearance) or catatonic behavior (eg, staying in the same position for an extended period of time)
  • Absence of emotional expression (your face seems blank) or absence of spontaneous speech or lack of desire or motivation to pursue any goals

These symptoms significantly interfere with your ability to care for yourself, your general functioning, and your relationships. Your health care professional may discuss some or all of the above symptoms with you. It's important to openly share your feelings with him or her.

Important Safety Information About SEROQUEL XR

Elderly patients with dementia-related psychosis (having lost touch with reality due to confusion and memory loss) treated with this type of medicine are at an increased risk of death, compared to placebo (sugar pill). SEROQUEL XR is not approved for treating these patients.

Antidepressants have increased the risk of suicidal thoughts and actions in some children, teenagers, and young adults. Patients of all ages starting treatment should be watched closely for worsening of depression, suicidal thoughts or actions, unusual changes in behavior, agitation, and irritability. Patients, families, and caregivers should 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. These symptoms should be reported immediately to the doctor. SEROQUEL XR is not approved for children under the age of 10 years.

    Do not take SEROQUEL XR if you are allergic to quetiapine fumarate or any of the ingredients in SEROQUEL XR.

    Stroke that can lead to death can happen in elderly people with dementia who take medicines like SEROQUEL XR.

    Stop SEROQUEL XR and call your doctor right away if you have some or all of the following symptoms: high fever; excessive sweating; stiff muscles; confusion; changes in pulse, heart rate, and blood pressure. These may be symptoms of a rare, but very serious and potentially fatal, side effect called neuroleptic malignant syndrome (NMS).

    High blood sugar and diabetes have been reported with SEROQUEL XR and medicines like it. If you have diabetes or risk factors such as obesity or a family history of diabetes, your doctor should check your blood sugar before you start taking SEROQUEL XR and also during therapy. If you develop symptoms of high blood sugar or diabetes, such as excessive thirst or hunger, increased urination, or weakness, contact your doctor. Complications from diabetes can be serious and even life threatening.

    Increases in triglycerides and in LDL (bad) cholesterol and decreases in HDL (good) cholesterol have been reported with SEROQUEL XR. Your doctor should check your cholesterol levels before you start SEROQUEL XR and during therapy.

    Weight gain has been reported with SEROQUEL XR. Your doctor should check your weight regularly.

    Tell your doctor about any movements you cannot control in your face, tongue, or other body parts, as they may be signs of a serious condition called tardive dyskinesia (TD). TD may not go away, even if you stop taking SEROQUEL XR. TD may also start after you stop taking SEROQUEL XR.

    Other risks include feeling dizzy or lightheaded upon standing, falls (which may cause serious injuries), decreases in white blood cells (which can be fatal), or trouble swallowing. Tell your doctor if you experience any of these.

    Before starting treatment, tell your doctor about all prescription and nonprescription medicines you are taking. Also tell your doctor if you have or have had low white blood cell count, seizures, abnormal thyroid tests, high prolactin levels, heart or liver problems, or cataracts. An eye exam for cataracts is recommended at the beginning of treatment and every 6 months thereafter.

    Since drowsiness has been reported with SEROQUEL XR, you should not participate in activities such as driving or operating machinery until you know that you can do so safely. Avoid becoming overheated or dehydrated while taking SEROQUEL XR. Do not drink alcohol while taking SEROQUEL XR.

    Tell your doctor if you are pregnant or intend to become pregnant. Avoid breast-feeding while taking SEROQUEL XR.

    The most common side effects are drowsiness, dry mouth, constipation, dizziness, increased appetite, upset stomach, weight gain, fatigue, disturbance in speech and language, and stuffy nose.

    Do not stop taking SEROQUEL XR without talking to your doctor. Stopping SEROQUEL XR suddenly may cause side effects.
