I had the same issue here last month. I corresponded with an addiction specialist who explained that it is possible (but clearly not common) to absorb some naloxone and get a positive for naloxone metabolites via appropriate dosing and routes with buprenorphine/naloxone. However, remember that noroxymorphone is an oxymorphone metabolite as well so our patients could also have had some Opana in the recent past too.

could they be swallowing much of the medication and absorbing naloxone that way?

I would discuss with the lab toxicologist.
