Yes it is. Avinza, an extended use form of morphine, is a rather strong narcotic (opiate-type) drug. It's typically used when other narcotic drugs or other pain reliever do not work and offers long-lasting pain relief.
Because it's intended to be released slowly over time its very important take Avinza as instructed (i.e. don't break it up). That capsule has lot of narcotic pain relievers in it - to much to be taken safely at one shot. Its important to let pill slowly release its medication in your system as its intended to do.
Good luck with the Avinza.
