Generic Wellbutrin XL
Wellbutrin XL vs. Generic Versions
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 generic versions are equivalent to the brand-name medications and assigns a rating to each one.
However, generic medications are allowed to have different inactive ingredients from the brand-name medication. This might include fillers, dyes, or other ingredients, which could cause problems for people with certain allergies or sensitivities.
