It will not: Lidocaine is not a narcotic or other controlled substance and will not show up on tox screens. Lidocaine patches are safe, and are extremely effective for some types of pain, either by themselves or in combination with other medications. Nevertheless, please be careful about using prescription mess that are not your own
