Secondary Uses of Fluphenazine Medicine

However, these secondary uses require careful consideration due to the risk of side effects. Fluphenazine dosage must be adjusted precisely to avoid complications. While not commonly used for non-psychotic conditions, the medicine's powerful dopamine-blocking effects can support treatment in resistant cases under strict medical observation.

How Does Fluphenazine Tablet Work?

Fluphenazine tablet works by blocking dopamine receptors in the brain, specifically the D2 receptors. Dopamine is a chemical that plays a major role in mood, behaviour, and cognition. When dopamine is overactive, it can lead to symptoms like hallucinations or delusions. Fluphenazine reduces this overactivity, helping restore chemical balance. Unlike newer antipsychotics, it doesn't significantly affect serotonin. Its targeted dopamine suppression is what makes fluphenazine 5 mg tablets a reliable option in managing chronic psychotic disorders.
