Thiothixene is used to treat certain mental/mood disorders (such as schizophrenia). This medicine helps you to think more clearly, feel less nervous, and take part in everyday life. It can reduce aggression and the desire to hurt yourself/others. It may also help to decrease hallucinations (such as hearing/seeing things that are not there). Thiothixene is a psychiatric medication (antipsychotic-type) that works by helping to restore the balance of certain natural substances (such as dopamine) in the brain.
Take this medication by mouth with or without food, usually 1-3 times daily or as directed by your doctor.

Take this medication regularly in order to get the most benefit from it. To help you remember, take it at the same time(s) each day.
