Check the G&W Laboratories brand. What we have has a sticker with barcode on each suppository. Our wholesaler is McKesson so I am sure you can also get this brand. Let me know if this helps you out. :)
Gw is my contracted item but I was getting some that had bar codes and some that didnt. I got approval from the director to go off contract with this one and but the Paddock brand. They are plastic coated with the bac code imbeded into the plastic. They work great here.
