Could taking vicodin let me get a tattoo without feeling any pain?

Vicodin and tattoo. Firstly - having a tattoo is not painless. Secondly none of the "tattoo parlors" are permitted by law to provide pain medication. Secondly i dopubt very much if any md will give you this opioid just to get a tattoo - expect them to tell you to take a Motrin and tylenol (acetaminophen) for the tattoo.
No. Even though vicodin (hydrocodone) may be used for management of post-operative pain, it does not have much application for treatment of pain associated while getting a tattoo. You may see your physician and perhaps ask for a local anesthetic cream which may be applied to the skin prior to getting the tattoo.
