You can buy generic Seroquel (quetiapine) tablets in six strengths. At this time, Teva is the only company providing generic versions of this drug, but other companies may begin making their own generics in the future. The U.S. Food and Drug Administration considers the generic versions equivalent to brand-name Seroquel. However, they may have different inactive ingredients.

At this point, only one manufacturer (Teva Pharmaceutical Industries, Ltd.) is providing generic Seroquel, although in the future many companies are expected to begin selling other generic versions as well.
All generic medications must undergo certain tests to compare them to brand-name medications. The U.S. Food and Drug Administration (FDA) then looks at these tests to decide if the generics are equivalent to the brand-name medications and assigns a rating to each one.
An "AB" rating means that the FDA has determined that a generic medication is equivalent to a brand-name medication. The generic Seroquel products currently available have an "AB" rating, meaning they should be equivalent to Seroquel.
However, generic medications are allowed to have different inactive ingredients than the brand-name medication. This might include fillers, dyes, or other ingredients that may cause problems for people with allergies or sensitivities.
