The doctor told me it was the extended realease of Dilaudid. He said it would keep my pain more moderated since the other I was taken every four hours. He said that it had not been offered here in the US for long but it was offered in Europe under the name Jurnista. Just curious if any one has any experience with it as it is so new and I was only taken 4mg and now it will be 12mg. Thanks for the info and the link look forward to reading about it. Thanks Angela!
