Potency of oxycodone T 192?

I've found the Camber brand makes me itchy comparable to hives but without the red welts. And no, I'm not taking too much and having the 'opiate' itch. I take my meds as prescribed 1 every 6 hours. The itching starts before the pain relief. My best guess is there is a sulfa additive because that's the only thing I'm allergic to but that gives me full blown hives. So it must be a small amount of additive. I did write the company and they apologized but wanted me to talk to a rep and fill out a 20 page something questionnaire that had very personal questions that had nothing to do with the drug. Umm... nope!! Wondering if anyone else has had a similar side effect? Thank you!!

My pharmacy just gave me this pill for the first time. I have been taking it for 5 days with hardly no relief what so ever and I get an upset stomach every time I take it. When I was picking up my script two people ahead of me were told that the manufacture for their scripts had changed but they didn't tell me. I realized it when I got home. When I go to the pharmacy can I ask not to be given this manufacture or do i have to take what they give me?

I agree. Called pharmacy a few times and spoke to 3 different pharmacist. Finally was told the filler is different between manufacturers and can cause effectiveness to vary in each individual. I definitely do not get the relief I did from from what they were filling rx, which was a white round tablet A349 by Actavis
