Ursodiol is used to dissolve gallstones in patients with gallstones. It can also be used to prevent the formation of gallstones in certain patients.
Ursodiol is a prescription medication used to non-surgically treat and prevent gallstones. Ursodiol is a bile acid, a natural substance produced by the liver. It helps to decrease the formation of gallstones by dissolving the cholesterol necessary to make gallstones and suppressing production of cholesterol in the liver and absorption in the intestines.
Ursodiol comes in capsule and tablet form. It is taken 2 or 3 times daily, with food.
Common side effects include upset stomach, headache, and upper respiratory tract infections.
Usodiol can cause dizziness. Do not drive or operate heavy machinery until you know how it affects you.
