From the Guidelines
Fluphenazine (Prolixin) is generally indicated for acute and chronic psychotic disorders, particularly when long-acting formulations are needed, whereas flupentixol (Depixol) is often preferred for patients with prominent negative symptoms of schizophrenia or those with concurrent depressive symptoms. The primary distinction between these two typical antipsychotics lies in their formulation options and side effect profiles. Fluphenazine is available as oral tablets, short-acting injections, and long-acting depot injections (fluphenazine decanoate), making it suitable for patients with poor medication adherence 1. In contrast, flupentixol is often chosen for its potential to address negative symptoms of schizophrenia and its mild antidepressant effect, which can be beneficial in patients with mixed psychotic and depressive symptoms.
Key Considerations
- Fluphenazine's long-acting depot injection can be administered every 2-4 weeks, providing a convenient option for patients who struggle with daily medication adherence.
- Flupentixol's oral doses typically range from 3 to 18 mg daily, and its depot injection is also given every 2-4 weeks.
- Both medications can cause extrapyramidal symptoms, but flupentixol may have a slightly lower risk.
- The choice between fluphenazine and flupentixol should be based on the patient's symptom profile, history of response to antipsychotics, and the need for long-acting formulations.
Treatment Approach
When selecting between fluphenazine and flupentixol, consider the following:
- Start with low doses and titrate carefully to minimize side effects while achieving therapeutic benefit.
- Monitor patients closely for extrapyramidal symptoms and adjust the dosage or switch to another agent if necessary.
- Be aware of the potential for irreversible tardive dyskinesia, which can develop in 50% of elderly patients after continuous use of typical antipsychotic agents for 2 years 1.

From the Research
Indications for Fluphenazine (Prolixin) versus Flupentixol (Depixol)
The indications for fluphenazine (Prolixin) and flupentixol (Depixol) can be compared based on their effects on schizophrenia treatment.
- Fluphenazine is a typical antipsychotic used to treat schizophrenia, with studies showing its effectiveness in reducing symptoms 3, 4, 5.
- Flupentixol, on the other hand, has been shown to have an elating effect, making it more suitable for patients with lowered mood or a history of depression 6.
Comparison of Fluphenazine and Flupentixol
Key differences between fluphenazine and flupentixol include:
- Mood effects: Flupentixol has an elating effect, while fluphenazine tends to lower mood 6.
- Treatment of acute schizophrenia: Fluphenazine may be more suitable for elated or acutely disturbed patients, while flupentixol may be more suitable for patients with lowered mood 6.
- Comparison to other antipsychotics: Fluphenazine has been compared to atypical antipsychotics, such as amisulpride, risperidone, quetiapine, and olanzapine, with mixed results 3, 4.
Clinical Use
In clinical practice, the choice between fluphenazine and flupentixol may depend on the individual patient's symptoms and history.
- Fluphenazine may be preferred for patients with acute schizophrenia who are elated or agitated 6.
- Flupentixol may be preferred for patients with schizophrenia who have a history of depression or lowered mood 6. It is essential to consider the potential side effects and benefits of each medication when making treatment decisions 3, 4, 5.
