Here's the company's website. It is referred to as an opioid with abuse potential. However, in hospitals it has not always been treated the same as other narcotics. Often was sent by pharmacy to pts drug cassette, as opposed to being kept in Pyxxis. This may have changed since I was last acting as bedside RN 3 1/2 years ago. MDs seem more likely to Rx large quantities easier than with Percocet. (Ultram is a symthetic opioid)
I have found it's effects to vary widely. It has always relieved pain well, but at times has made me feel "loopy." My sister has had similar results.
