I’ve attached his entire eleven page report in PDF format below, but here’s one of the major conclusions he came to:
This leads me to believe that the Duragesic fentanyl patches are defectively designed. Certainly, I’d only use a Duragesic patch if I would literally rather die than suffer from whatever pain I’m in. Especially since I don’t know how permeable my skin is. Skin permeability plays a part in determining how much fentanyl you absorb from the patch. If you have superpermeable skin, you’re more likely to absorb a lethal amount of fentanyl. The more I learn about the patch from reading documents produced in litigation, the more wary I become of Duragesic and fentanyl patches.
Here is Dr. Prausnitz’ expert report from this lawsuit in PDF format.
