Quetiapine is generic for what drug?

What drug is quetiapine generic for?

Quetiapine is the generic name for the brand drug Seroquel (quetiapine fumarate). [1]

Does quetiapine also correspond to any other Seroquel brands?

Quetiapine is used for both immediate-release and extended-release versions that were marketed under brand names such as Seroquel XR (depending on the formulation). The active ingredient in these products is still quetiapine. [1]

How to check if a specific prescription is “quetiapine = Seroquel”

Look at the drug’s active ingredient on the label. If it says “quetiapine” (or “quetiapine fumarate”), it matches the same active drug as Seroquel, even if the tablet is branded differently or listed as extended-release. [1]
