Hi I have been prescribed this from my pain management Doc,Not received it as yet because my GP can't give me it or any pharmacist so it comes direct from a Hospital I don't know the reason behind this?

After a search on here is showed up a cancer concern.
Has anyone here Used it and had a Good experience with it or Bad? And how long have you been using it and Who prescribed it?

Sorry for so many Questions but I'm on that much medication as it is and hate taking it so don't want to add another in if it can do more harm than good.

Thankyou all in advance.


Take care G.

PS I'm in UK
