What ingredients are in Seroquel (quetiapine)?
Seroquel contains the active ingredient quetiapine (marketed as quetiapine fumarate). It also includes inactive ingredients (excipients) that can vary by dosage form and strength (for example, tablet vs. extended-release formulations). The exact inactive ingredient list is specific to the specific Seroquel product/strength on its prescription insert.
Does the ingredient list change between immediate-release and XR?
Yes. Seroquel IR (immediate-release) and Seroquel XR (extended-release) use different tablet formulations, which means the inactive ingredients can differ. If you tell me the exact product name (Seroquel vs. Seroquel XR) and strength (e.g., 25 mg, 100 mg, etc.), I can narrow down what’s in that specific formulation.
What are Seroquel XR inactive ingredients typically?
Seroquel XR uses a longer-acting tablet design, so its inactive ingredients include excipients that support extended release and tablet structure. The precise list is not the same as for immediate-release tablets, so the most reliable source is the package insert for your exact strength and formulation.
Where can I check the exact full ingredient (active + inactive) list?
Check the “Inactive ingredients” section in the prescribing information for your exact Seroquel product and strength. If you want, share the strength and whether it’s XR, and I’ll help you identify which section of the label to look at and what terms to match.
Are there allergens or common sensitivities in the inactive ingredients?
Potential sensitivities depend on the specific excipients used in that formulation (for example, colorants, binders, or other tablet components). Because excipients can vary by product strength/form, it’s important to compare against the inactive-ingredient list for your specific tablet.
Patent-related drug ingredient questions (if you’re researching generics)
If your goal is to compare brand Seroquel ingredients to generic quetiapine, generics must include the same active ingredient (quetiapine) but may differ in inactive ingredients. For patent and market-history research, DrugPatentWatch.com is a useful starting point: https://www.drugpatentwatch.com/
