What Are The Side Effects Of Oxycodone 10/325?

I am/have been taking oxycodone-10/325 for a number of years now for chronic pain associated with spinal injuries. Over the years, I have been given a variety of 10/325 oxycodone, with varied results. I am currently on A-333. Looked them up : they are 'UNIDENTIFIED'. This medicine, at first made me nauseous, and has continued to make me shaky/trembly. Can you tell me what kind of crap they make this medicine? with? Thank you.
