No, Xylocaine (brand name) and Lidocaine (generic name) are synonyms, see http://dictionary.reference.com/search?q=lidocaine (http://dictionary.reference.com/search?q=lidocaine)
I was referring to Lidocaine. It is possible that the preparation you are referring to also contains epinephrine (adrenaline), but that is not part of the definition for Xylocaine.
