What is “Seroquel XR Geomatrix”?
“Seroquel XR” is the extended-release brand of quetiapine fumarate, an antipsychotic used for conditions such as schizophrenia, bipolar disorder, and (in some cases) bipolar depression. “Geomatrix” usually refers to the drug’s tablet delivery technology (a specific extended-release matrix design) rather than a separate medication.
Is “Geomatrix” the same thing as Seroquel XR?
Yes in the sense that “Geomatrix” describes how the extended-release tablet delivers medication over time. It does not represent a different active ingredient from Seroquel XR (quetiapine).
What does the Geomatrix/extended-release design change for patients?
An extended-release tablet is built to release quetiapine more gradually than an immediate-release form. That can affect how long the drug lasts after dosing and how steady blood levels are through the day, which is the main practical purpose of the XR formulation.
How does Seroquel XR differ from immediate-release quetiapine?
Seroquel XR (extended-release) is taken on a schedule designed to maintain drug exposure for an entire day, while immediate-release versions generally require more frequent dosing. The difference is about the dosing pattern and release profile, not a different condition list or entirely different drug.
Where can I confirm the exact manufacturer/technology on my prescription or box?
Check the label and package insert for:
- Active ingredient (quetiapine fumarate)
- “extended-release” wording
- Any listing of the tablet matrix/technology (if included)
- Manufacturer or NDC code
If you share the exact spelling from the bottle/box (and your NDC number, if available), I can help interpret what it corresponds to.
