When should you not take quetiapine?

Quetiapine may not be appropriate for everyone, and there are certain situations where it should not be taken. Here are some examples of when quetiapine should not be taken:

  1. Allergies: If you are allergic to quetiapine or any of its ingredients, you should not take this medication.
  2. Medical conditions: Quetiapine may not be safe for individuals with certain medical conditions, such as liver or kidney disease, low blood pressure, or a history of heart problems. It may also interact with other medications, such as antidepressants or antihypertensive drugs.
  3. Pregnancy and breastfeeding: Quetiapine may not be safe for use during pregnancy or while breastfeeding, as it may cause harm to the developing fetus or newborn.
  4. Elderly patients with dementia: Quetiapine may increase the risk of death in elderly patients with dementia-related psychosis.

It is important to discuss any medical conditions, allergies, or medications with a healthcare provider before taking quetiapine or any other medication. They can help determine whether quetiapine is safe and appropriate for you based on individual needs and medical history.


There are various forms of drugs available, such as tablets or liquids, and each may have a separate patient information leaflet (PIL) for different doses. It is important to refer to the PIL for the specific form and dose of the drug that you have been prescribed.
