Why is this medication prescribed?

Quetiapine is used to treat psychotic disorders and symptoms such as hallucinations, delusions, and hostility.

This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.

How should this medicine be used?

Quetiapine comes as a tablet to take by mouth. It is usually taken two or three times a 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.

Quetiapine controls the symptoms of a psychotic disorder but does not cure it. Continue to take quetiapine even if you feel well. Do not stop taking quetiapine without talking to your doctor. Your doctor will probably want to decrease your dose gradually.

What special precautions should I follow?

Before taking quetiapine,

  • tell your doctor and pharmacist if you are allergic to quetiapine or any other drugs.
  • tell your doctor and pharmacist what prescription and nonprescription medications you are taking, especially amantadine (Symadine, Symmetrel), barbiturates, bromocriptine (Parlodel), carbamazapine (Tegretol), cimetidine (Tagamet, Tagamet HB), erythromycin, fluconazole (Diflucan), glucocorticoids (cortisone, hydrocortisone, prednisone, prednisolone, dexamethasone), itraconazole (Sporanox), ketoconazole (Nizoral), levodopa (Larodopa, Dopar, Sinemet), lorazepam (Ativan), medications for high blood pressure, pergolide (Permax), phenobarbital (Luminal), phenytoin (Dilantin), pramipexole (Mirapex), rifampin (Rifadin, Rimactane), selegiline (Eldepryl), thioridazine (Mellaril), and vitamins.
  • tell your doctor if you have or have ever had Alzheimer's disease, seizures, or heart or liver disease.
  • tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you become pregnant while taking quetiapine, call your doctor.
  • if you are having surgery, including dental surgery, tell your doctor or dentist that you are taking quetiapine.
  • you should know that this drug may make you drowsy. Do not drive a car or operate machinery until you know how quetiapine will affect you.
  • remember that alcohol can add to the drowsiness caused by this drug.
  • you should avoid activities that will cause your body to overheat or become dehydrated.
  • you should get up slowly when sitting or lying down. Standing quickly may cause you to become dizzy or faint.

What should I do if I forget a dose?

Take the missed dose as soon as you remember it. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.

  • dizziness

  • dry mouth
  • constipation
  • upset stomach
  • stomach pain
  • headache
  • tiredness
  • excessive weight gain

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom). Throw away any medication that is outdated or no longer needed. Talk to your pharmacist about the proper disposal of your medication.

In case of emergency/overdose

What other information should I know?

Do not let anyone else take your medication. Ask your pharmacist any questions you have about refilling your prescription.
