Thioridazine is an antipsychotic medication used to treat schizophrenia and other mental health conditions. It is part of a class of medications known as phenothiazines, which work by blocking dopamine receptors in the brain to reduce psychotic symptoms such as hallucinations, delusions, and disorganized thinking. Thioridazine can be taken orally or by injection. Common side effects include drowsiness, dry mouth, and blurred vision. It may also cause an irregular heart rhythm and low white blood cell count, which can be serious and require medical attention.
Thioridazine was previously a medication used to treat schizophrenia and psychosis, but it's no longer widely used due to safety concerns. Here's a breakdown of what you should know about thioridazine:
Medication Class:
- First-generation antipsychotic (also called a typical antipsychotic or phenothiazine) [1, 2].
What it did:
- Helped manage symptoms of schizophrenia, such as hallucinations, delusions, and disorganized thinking, by affecting certain brain chemicals [1].
Why it's not used anymore:
- Increased risk of a serious heart rhythm problem called QT prolongation, which can lead to sudden death [1, 2, 3].
- Safer and more effective medications are now available for treating schizophrenia.
Important Safety Information:
- Thioridazine was withdrawn from the market worldwide in 2005 because of the cardiac risks [2].
- If you were prescribed thioridazine in the past, you should no longer be taking it and should be on a different medication.
Alternatives:
- There are many other antipsychotic medications available that can effectively treat schizophrenia with a lower risk of severe side effects. It's important to talk to your doctor about the best course of treatment for you.
Additional Notes:
- Thioridazine may have caused other side effects, such as drowsiness, movement disorders, and dry mouth [2].
