Janssen Pharmaceuticals, Inc. mislabeled a box of Duragesic patches (a powerful pain reliever), marking the box as containing 25mg patches, but the box contained 100mg patches. Mr. Stanley placed a patch on his back to provide relief of his severe back pain. Instead of receiving the 25mg dose, he received the 100mg dose, which is four times the recommended amount. He went into a coma and eventually died.
