Chlorpromazine is an antipsychotic medication used to treat many conditions that affect the brain and nervous system, including schizophrenia, bipolar disorder, and ongoing hiccups. It works by blocking certain chemicals in the body, like histamine and dopamine.

Summary for Thioridazine

Prescription only

Thioridazine, previously known under the brand name Mellaril, treats adults and children with schizophrenia. This first-generation antipsychotic, or also called typical antipsychotic, is typically used only when other antipsychotic medications haven't worked well. Thioridazine tablets are taken by mouth a few times throughout the day. The dosage depends on how well the medication is helping with your symptoms and whether you're having side effects like dry mouth, sleepiness, and nausea. Thioridazine can also cause a serious heart rhythm problem called QT prolongation, so it's not a first-choice option.

Indications for Thioridazine

Schizophrenia when other antipsychotic medications haven't worked well or have caused bothersome side effects

Pros and Cons for Thioridazine

Pros

Less risk for weight gain than with atypical antipsychotics

Can't take with certain medications, such as fluoxetine (Prozac) and propranolol (Inderal), because it raises the risk for dangerous changes in heart rhythm
