Urso is used for:
Treating and preventing gallstones. It may also be used for other conditions as determined by your doctor.
Urso is a bile acid naturally found in the body. It works by dissolving the cholesterol that makes gallstones and inhibiting production of cholesterol in the liver and absorption in the intestines, which helps to decrease the formation of gallstones. It can also reduce the amount of other bile acids that can be harmful to liver cells when levels are elevated.

- you have blockage of the bile duct
