Key takeaways
Olanzapine (Zyprexa) and fluphenazine are both antipsychotic medications used to treat mental health conditions, but they have some important differences. Olanzapine is an atypical antipsychotic, while fluphenazine is a typical antipsychotic. Both medications are used to treat psychotic disorders, but olanzapine is also FDA-approved for treating schizophrenia and bipolar I disorder and can be used with fluoxetine for certain types of depression. Fluphenazine is primarily used for psychotic disorders. Olanzapine is typically taken once daily, either orally or as an injection, while fluphenazine is taken multiple times a day or as a long-acting injection every 4 to 6 weeks. Olanzapine is available as a generic and can cause sleepiness and weight gain. Fluphenaziner is also available as a generic and can cause drowsiness and movement problems. Both medications can cause serious side effects like neuroleptic malignant syndrome, but fluphenazine has a higher risk of causing movement disorders like tardive dyskinesia. Additionally, both medications are not generally recommended in older adults with dementia-related psychosis due to an increased risk of death.
