Rare but potentially serious adverse effects

Elderly individuals with dementia-related psychosis treated with antipsychotic medication are at an increased risk of death compared to individuals not receiving antipsychotics.

Drug interactions

Medications for allergies (e.g., Benadryl diphenhydramine), certain medications for sleep (e.g., lorazepam, zopiclone), certain medications for pain (e.g., fentanyl), and Antiparkinson medications can increase the sedative effect of thioproperazine and can be potentially dangerous when used together.
