Generic Name: chenodiol (KEE-noe-DYE-ol)
Brand Name: Chenodal
Chenodiol is used for:
Treating gallstones in certain patients. It may also be used for other conditions as determined by your doctor.
Chenodiol 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.
Do NOT use chenodiol if:
- you are allergic to any ingredient in chenodiol
- you are pregnant
- you have certain liver problems or bile duct problems (eg, blockage, inflammation, biliary cirrhosis)
- you have certain gallbladder problems or certain types of gallstones
- you have complications from gallstones or you will be having gallbladder surgery
Contact your doctor or health care provider right away if any of these apply to you.
