Use in Older Adults:
Studies have shown that older adults with dementia (a brain disorder that affects the ability to remember, think clearly, communicate, and perform daily activities and that may cause changes in mood and personality) who take antipsychotics (medications for mental illness) such as quetiapine have an increased risk of death during treatment.
Quetiapine is not approved by the Food and Drug Administration (FDA) for the treatment of behavioral problems in older adults with dementia. Talk to the doctor who prescribed this medication if you, a family member, or someone you care for has dementia and is taking quetiapine. For more information visit the FDA website: http://www.fda.gov/Drugs
Risk of Suicidality:
A small number of children, teenagers, and young adults (up to 24 years of age) who took antidepressants ('mood elevators') such as quetiapine during clinical studies became suicidal (thinking about harming or killing oneself or planning or trying to do so). Children, teenagers, and young adults who take antidepressants to treat depression or other mental illnesses may be more likely to become suicidal than children, teenagers, and young adults who do not take antidepressants to treat these conditions. However, experts are not sure about how great this risk is and how much it should be considered in deciding whether a child or teenager should take an antidepressant. Children younger than 10 years of age should not normally take quetiapine, but in some cases, a doctor may decide that quetiapine is the best medication to treat a child's condition.
You should know that your mental health may change in unexpected ways when you take quetiapine or other antidepressants even if you are an adult over age 24. You may become suicidal, especially at the beginning of your treatment and any time that your dose is increased or decreased. You, your family, or your caregiver should call your doctor right away if you experience any of the following symptoms: new or worsening depression; thinking about harming or killing yourself, or planning or trying to do so; extreme worry; agitation; panic attacks; difficulty falling asleep or staying asleep; aggressive behavior; irritability; acting without thinking; severe restlessness; and frenzied abnormal excitement. Be sure that your family or caregiver knows which symptoms may be serious so they can call the doctor when you are unable to seek treatment on your own.
Your healthcare provider will want to see you often while you are taking quetiapine, especially at the beginning of your treatment. Be sure to keep all appointments for office visits with your doctor.
The doctor or pharmacist will give you the manufacturer's patient information sheet (Medication Guide) when you begin treatment with quetiapine. Read the information carefully and ask your doctor or pharmacist if you have any questions. You also can obtain the Medication Guide from the FDA website: http://www.fda.gov/Drugs/DrugSafety/InformationbyDrugClass/UCM096273.
No matter what your age, before you take an antidepressant, you, your parent, or your caregiver should talk to your doctor about the risks and benefits of treating your condition with an antidepressant or with other treatments. You should also talk about the risks and benefits of not treating your condition. You should know that having depression or another mental illness greatly increases the risk that you will become suicidal. This risk is higher if you or anyone in your family has or has ever had bipolar disorder (mood that changes from depressed to abnormally excited) or mania (frenzied, abnormally excited mood) or has thought about or attempted suicide. Talk to your doctor about your condition, symptoms, and personal and family medical history. You and your doctor will decide what type of treatment is right for you.
Quetiapine tablets and extended-release (long-acting) tablets are used to treat the symptoms of schizophrenia (a mental illness that causes disturbed or unusual thinking, loss of interest in life, and strong or inappropriate emotions). Quetiapine tablets and extended-release tablets are also used alone or with other medications to treat episodes of mania (frenzied, abnormally excited or irritated mood) or depression in patients with bipolar disorder (manic depressive disorder; a disease that causes episodes of depression, episodes of mania, and other abnormal moods). In addition, quetiapine tablets and extended-release tablets are used with other medications to prevent episodes of mania or depression in patients with bipolar disorder. Quetiapine extended-release tablets are also used along with other medications to treat depression. Quetiapine tablets may be used as part of a treatment program to treat bipolar disorder and schizophrenia in children and teenagers. Quetiapine is in a class of medications called atypical antipsychotics. It works by changing the activity of certain natural substances in the brain.
Quetiapine comes as a tablet and an extended-release tablet to take by mouth. The tablets are usually taken one to three times a day, with or without food. The extended-release tablets are usually taken once a day in the evening without food or with a light meal. Take quetiapine at around the same time(s) every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take quetiapine exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Swallow quetiapine extended-release tablets whole; do not split, chew, or crush them.
Your doctor will probably start you on a low dose of quetiapine and gradually increase your dose during the first week of your treatment. Ask your doctor or pharmacist if you have any questions about the amount of medication you should take each day at the beginning of your treatment.
If you do not take quetiapine for one week or longer, you should call your doctor before you start taking the medication again. Your doctor will probably tell you to start taking a low dose of the medication and gradually increase your dose as you did when you first started taking quetiapine.
Quetiapine may help control your symptoms but will not cure your condition. Continue to take quetiapine even if you feel well. Do not stop taking quetiapine without talking to your doctor. If you suddenly stop taking quetiapine, you may experience withdrawal symptoms such as nausea, vomiting, and difficulty falling asleep or staying asleep. Your doctor will probably want to decrease your dose gradually.
This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
