absorbed by the intestines. Ursodiol helps break down cholesterol that has formed into stones in
the gallbladder. Ursodiol also increases bile flow in patients with primary biliary cirrhosis.
Ursodiol is used to treat small gallstones in people who cannot have gallbladder surgery,
and to prevent gallstones in overweight patients undergoing rapid weight loss. Ursodiol is also
used to treat primary biliary cirrhosis.
Ursodiol is not for treating gallstones that are calcified.
Ursodiol may also be used for purposes other than those listed in this medication guide.
