I was given Ultracet to manage severe pain from sciatica. I was told that Ultracet was 'less addictive' than Percocet, which I'd been taking. What a disaster. The Ultracet faded out on me in less than three hours, leaving me in pain, and I developed severe stomach problems: acute, spasmadic cramps, inflamation of my stomach lining, and ultimately, gastritis. The doctor stopped the Ultracet as soon as I complained of the pain--by then, I could barely stand upright.
The gastritis is still a serious problem, months after stopping the Ultracet. I now have to take prescription medication for gastritis, and cannot take any pain reliever except acetomenophin. (For folks outside the U.S., even paracetamol aggravates the stomach.) This drug ruined my life. Everything, from my diet, to how I manage my pain, to how I perform my daily activities has had to be changed.
Please, please, PLEASE, discuss this option with your doctor before agreeing to take the 'less addictive' Ultracet.
