Four out of the five strengths of Symbyax (olanzapine and fluoxetine) are available in generic form. The FDA has determined that these generic medications are equivalent to brand-name Symbyax. However, the generic versions may have different inactive ingredients, which may cause problems for some people. At this time, Teva Pharmaceutical Industries is the only manufacturer of the generic versions.
Symbyax® (olanzapine and fluoxetine) is a prescription medication that is used to treat depression associated with bipolar disorder. It is also approved for treatment-resistant depression. It is a combination of two different medications: olanzapine (Zyprexa®) and fluoxetine (Prozac®).

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 versions of Symbyax currently available have an "AB" rating, meaning they should be equivalent to Symbyax.
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.
