"i was started on avinza after back surgery. it took a bit to get an effective dose as i had back pain of 8 on a 1-10 scale, constantly. since finding the correct dose for me, my doctor has only had to increase the avinza once. i also take lortab 10/500 on the average of once a day for breakthrough pain. this keeps the pain under control and i can work still. if it weren&#039;t for this drug, i would not be able to move without excruciating pain."
