Patient Education

Ursodiol


Ursodiol is used to dissolve gallstones in people who do not want surgery or cannot have surgery to remove gallstones. Ursodiol is also used to prevent the formation of gallstones in overweight people who are losing weight very quickly. Ursodiol is used to treat people with primary biliary cirrhosis (PBC; an autoimmune liver disease). Ursodiol is in a class of medications called gallstone dissolution agentss. It works by decreasing the production of cholesterol and by dissolving the cholesterol in bile to prevent stone formation and by decreasing toxic levels of bile acids that accumulate in primary biliary cirrhosis.
