Aripiprazole and Omeprazole Interaction
Drug interaction information between Aripiprazole and Omeprazole.
Aripiprazole and Omeprazole have a documented minor interaction in FDA labeling.
FDA drug labeling documents a minor-severity interaction between Aripiprazole and Omeprazole. Major interactions are generally avoided, moderate ones may need monitoring or a dose adjustment, and minor ones are usually low-risk. This page shows the documented mechanism and guidance. Label-documented interactions are not a complete safety review, so always confirm your own medications with a pharmacist or doctor. Educational information, not medical advice.
How They Interact
Aripiprazole does not change how your body processes omeprazole, so the levels of the medicine in your blood stay the same.
What To Do
No dose adjustments are necessary when taking these two medications together.
FDA Label Information
In addition, no dosage adjustment is necessary for substrates of CYP2D6 (e.g., dextromethorphan, fluoxetine, paroxetine, or venlafaxine), CYP2C9 (e.g., warfarin), CYP2C19 (e.g., omeprazole, warfarin, escitalopram), or CYP3A4 (e.g., dextromethorphan) when co-administered with aripiprazole.

Frequently Asked Questions
Can I take Aripiprazole and Omeprazole together?
This is a minor interaction. No dose adjustments are necessary when taking these two medications together.
How serious is the interaction between Aripiprazole and Omeprazole?

Why do Aripiprazole and Omeprazole interact?
Aripiprazole does not change how your body processes omeprazole, so the levels of the medicine in your blood stay the same.
Understanding the Aripiprazole and Omeprazole Interaction
FDA-approved prescribing information for these two drugs flags their combination as a minor-severity interaction. Aripiprazole belongs to the Atypical Antipsychotic class and Omeprazole belongs to the Proton Pump Inhibitor (PPI) class - two categories that can collide when co-prescribed. The mechanism described in FDA labeling is: Aripiprazole does not change how your body processes omeprazole, so the levels of the medicine in your blood stay the same. Severity tiers matter: major flags generally advise avoidance, moderate flags often require monitoring or dose adjustment, and minor flags may only call for awareness.
Context around a specific patient determines real-world impact. Aripiprazole has 19 total documented interactions on file in this dataset, and Omeprazole has 27. Each additional medication compounds the interaction surface, which is why pharmacists run full-profile checks rather than evaluating one pair at a time. FDA-derived guidance for this pair is: No dose adjustments are necessary when taking these two medications together. Timing of doses, renal and hepatic function, age, and other concurrent prescriptions all shape whether a labeled interaction matters clinically.
An interaction flag is not a verdict. A large share of labeled interactions are managed routinely in clinical practice, the fix may be as simple as spacing doses or adding a monitoring test. Others require the prescriber to choose a different medication entirely.

Never start, stop, or adjust either Aripiprazole or Omeprazole based on a web page, speak with your prescriber or pharmacist before making any change.
