Hello inenigma, and welcome to NeuroTalk.

Unfortunately I'm no longer able to answer questions about Norspan because hubby's been off those Patches for a little over a year now.

He had major surgery last November and had to detox off them and because that wasn't very nice, he's not gone back on them. He takes a slow release oral pain medication instead now.

We've also moved from the Sydney area, but hopefully another of our Australians from NSW will see this and be able to help you out.

If it's general information that you want, may I suggest that you post in the Medication Forum? You may get more information there.
