Seroquel vs. Geodon
See how Seroquel and Geodon compare on approved uses, dosing, side effects, and cost.
Key Takeaways
Seroquel and Geodon are both atypical antipsychotics used for schizophrenia and bipolar disorder, but they differ in dosing schedules, side-effect profiles, and additional FDA-approved uses.
Seroquel is the only one of the two approved for bipolar depression and, in its extended-release form, as an add-on for major depressive disorder.
Geodon carries a higher risk of QT prolongation and must be taken with a substantial meal, but it offers a short-term injectable option for acute agitation that Seroquel does not.
Seroquel vs. Geodon Drug Summary
Seroquel
Seroquel (quetiapine) is an atypical antipsychotic that treats schizophrenia, bipolar disorder, and, as an add-on, major depressive disorder. It's taken as a tablet, once or twice daily depending on the formulation, with the dose raised gradually.
Geodon
Geodon (ziprasidone) is an atypical antipsychotic used to treat schizophrenia and to manage manic or mixed episodes of bipolar disorder. It's taken as a capsule twice daily with food, and a separate injectable form treats acute agitation in schizophrenia.

Seroquel vs. Geodon Indications
Seroquel
Seroquel is FDA-approved for schizophrenia in adults and teens, acute manic and depressive episodes of bipolar disorder, and long-term bipolar maintenance with lithium or divalproex. Its extended-release form is also approved as an add-on treatment for major depressive disorder.
Schizophrenia (adults and teens 13-17)
Acute bipolar I manic or mixed episodes
Acute bipolar depressive episodes
Bipolar I maintenance (adjunct to lithium/divalproex)
Geodon
Geodon is FDA-approved for schizophrenia in adults and for acute manic or mixed episodes of bipolar disorder. It's also used long-term for bipolar maintenance alongside lithium or valproate, and an injectable form treats acute agitation in schizophrenia.
Schizophrenia in adults
Acute bipolar manic or mixed episodes
Bipolar maintenance (adjunct to lithium/valproate)
Acute agitation in schizophrenia (IM form)
Seroquel vs. Geodon Pros and Cons
Seroquel
Seroquel covers more phases of bipolar illness than many antipsychotics, including depressive episodes, and its extended-release form is also approved as an add-on for major depressive disorder. Its main tradeoffs are pronounced sedation and a higher likelihood of weight gain and metabolic changes that need ongoing monitoring.
Pros
Approved for bipolar depression, a phase many antipsychotics don't cover
Extended-release form allows once-daily dosing
XR form also approved as an add-on for major depressive disorder
Cons
Multi-day titration with several dose increases to reach target dose
No injectable form for acute agitation
Higher rates of sedation and weight gain than some atypicals
Requires ongoing metabolic monitoring (weight, blood sugar, lipids)
Geodon
Geodon offers a simple, fast dosing schedule and a short-term injectable option for acute agitation, an alternative Seroquel does not have. Its main tradeoff is a comparatively higher risk of QT prolongation, and capsules must be taken with a substantial meal for proper absorption.
Pros
Simple two-step dosing: start, then adjust every 2 days
Short-term intramuscular injection available for acute agitation
Effective for both manic and mixed bipolar episodes
Cons
Greater risk of QT prolongation than many other antipsychotics
Must be taken with a substantial meal (≥500 calories) to absorb
Not approved for bipolar depression or as a depression add-on
Contraindicated with other QT-prolonging drugs and recent heart problems
