For Chronic Pain "I was on 4 x 5 mg Oxycodone IR for my pain. After a year or so, I felt I needed an extra pill to cover me for 24 hrs. Doctor switched me to OxyNeo 2 x 10 mg every 12 hours plus 5 mg of Oxycodone for breakthrough if needed. The first 2 days I felt great, OxyNeo took care of the pain, and I did not feel drowsy or tired. However, after the 3rd day, I started feeling very agitated and angry after I took my OxyNeo. I'm not sure what's going on. Has anyone reacted like this to long-acting Oxycodone? Too bad because I liked this long-acting one, but feeling angry all day is not worth it either."

For Chronic Pain "I've been on OxyContin for 8 months. I take it to help with RSD pain in my shoulder that radiates all down my arm and into my hand. I have trouble taking high doses of nerve medications like gabapentin, so a narcotic is necessary. It definitely helps a lot. However, it does not last 12 hours. I have oxycodone for breakthrough pain. I also have tried taking 3 doses of OxyContin a day (per doctor's orders) and that keeps it from running out. The problem with a triple dose is drowsiness; I started to have trouble tolerating that. But overall, this has been a lifesaver for me."

For Pain "Personally, OxyContin takes care of the pain better than any other medicine, and instead of the drowsiness feeling, it gives me the energy to exercise and fit in with a healthy lifestyle. No breakthrough pain medicines needed at 80 mg twice a day."

For Pain "I currently take 80 mg OxyContin four times a day, although I sometimes try and see if I can manage on 2-3/day. I am 45 and will undergo hip replacement at the end of April. OxyContin allows me to feel normal, and most activities I used to do are doable. The best part is the absence of drowsiness and 'euphoria' I always associate with opiates, so it doesn't get me all loopy."
