Is quetiapine same as seroquel?

Are quetiapine and Seroquel the same drug?

Quetiapine and Seroquel are essentially the same medication. Seroquel is a brand name for quetiapine, which is the generic drug name [1].

What is the difference then—brand vs generic?

The active ingredient is quetiapine in both. The difference is usually the manufacturer and the formulation details (like filler ingredients), not the core medicine that treats symptoms [1].

Which version should I take?

If your prescription says “quetiapine,” it may refer to a generic product. If it says “Seroquel,” it refers to the brand. If you’re switching between brand and generic, it’s still the same drug, but ask your pharmacist if your dose and release type match (for example, immediate-release vs extended-release) [1].

Why does the exact product name matter (IR vs XR)?

Quetiapine products can come in different release forms (such as immediate-release and extended-release). Those versions are not interchangeable dose-for-dose, so the prescription wording matters [1].
