Studies have shown that older adults with dementia (a brain disorder that affects the ability to remember, think clearly, communicate, and perform daily activities and that may cause changes in mood and personality) who take antipsychotics (medications for mental illness) such as thiothixene have an increased chance of death during treatment.
Thiothixene is not approved by the Food and Drug Administration (FDA) for the treatment of behavior problems in older adults with dementia. Talk to the doctor who prescribed this medication if you, a family member, or someone you care for has dementia and is taking thiothixene. For more information, visit the FDA website: Web Site
WHY is this medicine prescribed?

Thiothixene is in a group of medications called conventional antipsychotics. It works by decreasing abnormal excitement in the brain.
HOW should this medicine be used?
