Compare Seroquel vs. Prolixin

Quetiapine (Seroquel) and fluphenazine are both medications used to treat mental health conditions, but they have some important differences. Quetiapine is an atypical antipsychotic, while fluphenazine is a typical antipsychotic. Both medications can be used to treat psychotic disorders, but quetiapine is also FDA-approved for bipolar disorder and as an add-on for depression, whereas fluphenazine is only approved for psychotic disorders. Quetiapine is available in immediate-release and extended-release oral tablets, while fluphenazine comes in oral tablets, liquid forms, and both short- and long-acting injections. Quetiapine is typically taken once to three times daily, depending on the form, while fluphenazine is taken three to four times daily or as a long-acting injection every 4 to 6 weeks. Common side effects of quetiapine include sleepiness, dry mouth, and dizziness, whereas fluphenazine can cause drowsiness, movement problems, and dry mouth. 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, quetiapine can interact with grapefruit and many other medications, while fluphenazine should not be mixed with apple juice or caffeinated drinks.
