SEROQUEL XR for Major Depressive Disorder

SEROQUEL XR may help improve your unresolved symptoms of depression when added to an antidepressant

SEROQUEL XR is FDA approved to treat major depressive disorder as add-on therapy to an antidepressant medication.

If you’ve taken an antidepressant for 6 weeks or more and are still experiencing symptoms of depression, talk to your doctor. He or she may consider adding a medication like SEROQUEL XR to help with your current treatment plan.

SEROQUEL XR is taken once daily as prescribed by your health care professional. Adding SEROQUEL XR to your current antidepressant may help further improve your unresolved symptoms of depression. And remember, adding SEROQUEL XR doesn’t mean having to start over, but it may mean starting to improve your unresolved symptoms.

It’s also important to remember that SEROQUEL XR has side effects—learn more about these possible side effects.

When studied in patients with unresolved depression already taking an antidepressant, adding SEROQUEL XR to an ongoing antidepressant was proven more effective than an antidepressant alone for treating unresolved symptoms of depression. Unresolved symptoms are those that remain despite initial treatment with an antidepressant after at least 6 weeks.

SEROQUEL XR was studied in more than 900 patients with depression. The patients in those studies had been on an antidepressant for at least 6 weeks, but were still experiencing symptoms of depression.* Those antidepressants included:

  • Cymbalta® (duloxetine)
  • Effexor® (venlafaxine)
  • Paxil® (paroxetine)
  • Prozac® (fluoxetine)
  • Zoloft® (sertraline)
  • Lexapro® (escitalopram)
  • Celexa® (citalopram)
  • Wellbutrin® (bupropion)
  • Amitriptyline

Patients may have received generic versions of these products.

All patients continued to take their antidepressant. Some of the patients were given a sugar pill (placebo) to add to their antidepressant, and the other patients were given SEROQUEL XR to add to their antidepressant.

The results of the studies showed that many patients taking SEROQUEL XR with an antidepressant had greater improvement in their depressive symptoms* than patients taking a sugar pill with an antidepressant.

*The test that was used is called the MADRS, which is a standard rating scale that measures a patient's level of depression.

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.
