Topic: pain/ Hydromorphone/ Vidatox

I have been prescribed hydromorphone. I find it helpful. I did have problems with constipation. I have been using lactulose  and senekot for the constipation and found that works very well. A friend brought me Vidatox from Cuba and I was wondering if anyone on here has heard of it or used it? I haven't tried it yet as I am waiting to speak to my Dr. about it first.
