URSODIOL is a bile acid. The drug helps dissolve gallstones in those who cannot have gallbladder surgery or who do not need the surgery. Ursodiol may be used with a procedural device that fragments the gallstone into smaller pieces; the procedure, called lithotripsy, allows the drug to dissolve the stones more quickly. Ursodiol is also useful for certain liver diseases of adults, children and infants; the drug reduces itching and other symptoms.

They need to know if you have any of these conditions:

• pancreatitis (an inflammation of the pancreas)
• an unusual or allergic reaction to ursodiol, bile acids, other medicines, foods, dyes, or preservatives
• pregnant or trying to get pregnant
• breast-feeding

Take ursodiol capsules or tablets by mouth. Follow the directions on the prescription label. Take the capsules with food or milk to improve absorption and limit stomach or intestinal side effects. Take your doses at regular intervals. Do not take your medicine more often than directed.
