Ursodiol: Uses, Dosage, Side Effects and More
Introduction: What is Ursodiol?
Ursodiol, also known as ursodeoxycholic acid (UDCA), is a bile acid that is naturally produced in small amounts by the liver. It is primarily used in the treatment of certain liver and gallbladder conditions. Ursodiol helps to dissolve cholesterol gallstones and improve liver function in patients with specific liver diseases. It is available in oral tablet form and is often prescribed to manage various biliary and hepatic disorders.
Uses of Ursodiol
Ursodiol is approved for several medical uses, including:
- Dissolving Cholesterol Gallstones: It is effective in treating patients with cholesterol gallstones who are not candidates for surgery.
- Primary Biliary Cholangitis (PBC): Ursodiol is used to slow the progression of this chronic liver disease, which damages the bile ducts.
- Liver Disease in Cystic Fibrosis: It may be prescribed to manage liver complications associated with cystic fibrosis.
- Nonalcoholic Fatty Liver Disease (NAFLD): Ursodiol can help improve liver function in patients with this condition.
How It Works
Ursodiol works by reducing the amount of cholesterol produced by the liver and decreasing the absorption of cholesterol from the intestines. It also helps to increase the solubility of cholesterol in bile, which can lead to the dissolution of cholesterol gallstones. In patients with liver diseases, Ursodiol helps to protect liver cells from damage and promotes better bile flow, which is essential for digestion and liver health.
Dosage and Administration
The dosage of Ursodiol varies based on the condition being treated:
- For Gallstones: The typical adult dosage is 810 mg/kg/day, divided into two or three doses. Treatment may continue for up to 24 months.
- For Primary Biliary Cholangitis: The usual adult dosage is 1315 mg/kg/day, taken in two or three doses.
- For Pediatric Use: Dosage is based on the child's weight and should be determined by a healthcare provider.
Ursodiol is taken orally in tablet form, usually with food to enhance absorption.

Common side effects may include:
- Diarrhea

Serious side effects, though rare, can include:
- Allergic reactions (rash, itching, swelling)

Patients should report any unusual symptoms to their healthcare provider.
Drug Interactions
Ursodiol may interact with certain medications, including:
- Cholestyramine: This cholesterol-lowering medication can reduce the effectiveness of Ursodiol.
- Antacids: Some antacids may interfere with Ursodiol absorption.
- Estrogens: Hormonal therapies may affect bile composition and should be discussed with a doctor.
Always inform your healthcare provider about all medications and supplements you are taking.

The clinical advantages of Ursodiol include:
- Non-Surgical Option: It provides a noninvasive alternative for patients with gallstones who wish to avoid surgery.
