It is sold by various manufacturers, such as CorePharma and Sandoz.

Is Generic Metaxalone as Good as Brand-Name Skelaxin?
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 each generic a rating.
An "AB" rating means that the FDA has determined that a generic medication is equivalent to a brand-name medication. The generic metaxalone tablets currently available have an "AB" rating, meaning they should be equivalent to Skelaxin.
However, generic medications are allowed to have different inactive ingredients than the brand-name medication. In some cases, these inactive ingredients may cause problems for people with allergies or sensitivities.
