Thioridazine is an antipsychotic medication used to treat schizophrenia and certain other mental health conditions. Here is information on the indication and dosage of thioridazine:

Indication:

• Thioridazine is indicated for the treatment of schizophrenia, a mental disorder characterized by disconnection from reality, hallucinations, and delusions.
• It may also be used to treat other psychotic disorders, depressive disorders, pediatric behavioral disorders, and geriatric psychoneurotic manifestations.

Dosage:

• The dosage of thioridazine must be individualized for each patient based on their response to treatment and medical condition.
• The usual starting dose of thioridazine is 10 mg to 25 mg taken two to four times a day.
• The dosage may be gradually increased as needed, with increments of 10 mg to 25 mg every two to three days, up to a maximum daily dose of 800 mg.
• It is important to use the smallest effective dosage to minimize the risk of side effects.
• Thioridazine should be taken by mouth with or without food, as directed by a doctor.
• It is important to follow the dosage instructions provided by the healthcare professional and not to change the dosage without their approval.

It's important to note that thioridazine has the potential to cause serious side effects, including a potentially life-threatening heart rhythm disorder called QT prolongation. Therefore, its use should be reserved for patients who fail to respond adequately to treatment with other antipsychotic drugs.

Please consult with a healthcare professional for personalized advice and guidance regarding the indication and dosage of thioridazine.
