How can I identify SEROQUEL XR?

Images are not actual size and color may vary slightly. |
When taking any prescription medicine, you want to make absolutely certain that what you are taking is what the doctor prescribed for you. If you go to the pharmacy and pick up a prescription that doesn't say SEROQUEL XR on the label, ask the pharmacist to call your doctor right away–or call the doctor yourself.
Make sure you are able to identify each medicine you take. This can help you to avoid mistakes that could be harmful to your health—for example, taking the wrong pill at the wrong time.
As the images show, SEROQUEL XR comes in different dosage strengths and the tablets are different colors, shapes and sizes, depending on the dosage strength. Your doctor will prescribe the amount of medicine that he or she feels is most appropriate for you when beginning treatment with SEROQUEL XR and during treatment.

Prescribing Information with your health care provider.
SEROQUEL XR is a once daily tablet approved to treat schizophrenia.
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.
Families and caregivers should watch patients daily and report these symptoms
immediately to the physician. SEROQUEL XR is not approved to treat depression.
SEROQUEL XR is not approved for patients under the age of 18 years.
-
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, ask your doctor about checking your blood sugar before
starting SEROQUEL XR and regularly throughout treatment. 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
-
A rare, but potentially fatal, side effect reported with SEROQUEL XR and
medicines like it is neuroleptic malignant syndrome (NMS). Tell your doctor if
you have very high fever; rigid muscles; shaking; confusion; sweating; changes
in pulse, heart rate, or blood pressure; or muscle pain and weakness because
treatment should be stopped if you have NMS
-
Another serious side effect reported with SEROQUEL XR and medicines like it is
tardive dyskinesia (TD)—uncontrollable movements of the face, tongue, or other
parts of the body. TD may become permanent, and the risk of TD is believed to
increase as the length of time on and the amount of these medications increase.
While TD can develop in patients taking low doses for short periods, this is
much less common. There is no known treatment for TD, but it may go away
partially or completely if treatment is stopped
-
Before starting treatment, tell your doctor if you have high cholesterol or
have a history of, or are at risk for, seizures or a low white blood cell (WBC)
count. An eye exam for cataracts is recommended at the beginning of treatment
and every 6 months thereafter. During treatment, tell your doctor if you feel
dizzy or lightheaded upon standing. Suicidal thoughts or actions may occur in
schizophrenia; tell your doctor if you have thoughts about death or suicide.
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 drinking alcohol while taking SEROQUEL XR because
SEROQUEL XR increases the effects of alcohol. Avoid becoming overheated or
dehydrated while taking SEROQUEL XR
-
Common side effects: The most common side effects are drowsiness, dry mouth, constipation, upset stomach, dizziness, a sudden drop in blood pressure upon standing, weight gain, increased hunger, tiredness, difficulty speaking, and stuffy nose.
