Medically reviewed.
Ursodeoxycholic acid (ursodiol) is a prescription medication used to treat certain cholestatic liver diseases, particularly primary biliary cholangitis (PBC). It is a naturally occurring bile acid that helps improve bile flow and reduce liver damage caused by bile duct injury. It is sold under the brand names Actigall, Urso, and Ursofalk. Treatment decisions should always be individualized and guided by a healthcare professional.

ABOUT URSODIOL TREATMENT
Ursodeoxycholic acid, also called ursodiol or UDCA, is a prescription medication. It is sold under the brand names Actigall, Urso, and Ursofalk. It is a naturally occurring bile acid.
Doctors use it to treat certain cholestatic liver diseases, which are conditions where bile flow is impaired. It is used most often for primary biliary cholangitis (PBC). Ursodiol helps improve bile flow and reduces liver damage caused by bile duct injury.
It is one part of a broader plan that includes regular monitoring, such as liver function tests, and healthy lifestyle habits.
WHO URSODIOL MAY BE SUITABLE FOR
Your healthcare provider may prescribe Actigall, Urso, or Ursofalk if you have primary biliary cholangitis, or if impaired bile flow is causing liver injury. It may also be chosen when you need first-line medical therapy for cholestatic liver disease, or when your provider wants to slow disease progression, preserve liver function, and improve liver enzyme levels and bile flow.
This matches current clinical guidance, which recommends ursodeoxycholic acid as first-line therapy for people with PBC who have abnormal liver enzyme values, regardless of disease stage.
Every patient's health profile is different, so there is no one-size-fits-all answer. Your provider decides whether ursodiol fits your care plan after assessing your liver condition, weight, and test results.
ELIGIBILITY OVERVIEW
Ursodiol may be considered for adults with the following conditions or treatment goals:
Your healthcare provider decides whether ursodiol is appropriate and sets the dose based on:
HOW URSODIOL CAN HELP YOUR LIVER
In cholestatic liver disease, bile does not flow well through the liver and bile ducts. Bile acids can then build up and injure liver cells.
Ursodiol is a naturally occurring bile acid. It improves bile flow and reduces the toxic effects of bile acid buildup. It also protects liver cells from bile-related injury and helps decrease liver inflammation.
Over time, these effects help slow the progression of cholestatic liver disease. Ursodiol is not used on its own. Providers pair it with regular monitoring, such as liver function tests, and healthy lifestyle habits.
LIVER BENEFITS
Bile is a fluid that carries waste out of the liver and helps the body digest fat. In cholestatic liver disease, it moves slowly through the liver and bile ducts. Ursodiol helps bile move more freely, which is the starting point for its other effects.
When bile backs up, bile acids build up and can harm liver cells. Ursodiol is a naturally occurring bile acid. It reduces these toxic effects and protects liver cells from bile-related injury.
Ongoing bile-related injury can inflame the liver. By easing that injury, ursodiol helps decrease liver inflammation.
With less injury and inflammation, cholestatic liver disease progresses more slowly. This helps preserve liver function. The effect builds with steady, long-term use.
Ursodiol improves bile flow and protects liver cells from bile-related injury. It should be started and monitored by a qualified healthcare professional.
TREATMENT PROCESS
Ursodiol is available as capsules and tablets. In some regions, it is also available as an oral suspension. Take it exactly as your healthcare provider directs.
The typical dose is 13–15 mg per kilogram of body weight per day. The daily amount is divided into two to four doses through the day. Your healthcare provider determines the right dose based on your weight, liver condition, and response to treatment.
Ursodiol is taken by mouth, with food or as your healthcare provider directs.
Ursodiol is generally a long-term, often lifelong treatment for primary biliary cholangitis and many other chronic cholestatic liver diseases. Continued therapy helps maintain improved bile flow, preserve liver function, and slow disease progression. Do not stop taking it without talking to your healthcare provider.
Store ursodiol at room temperature, away from moisture and heat.
Your healthcare provider will regularly monitor your liver function tests and your response to treatment. Report any side effects or unusual symptoms to your provider.
BENEFITS AND SAFETY
Ursodiol may support people with primary biliary cholangitis and other cholestatic liver diseases by improving bile flow and reducing bile acid-related liver injury. It is an established first-line treatment for PBC. The extent of benefit varies from person to person, depending on the liver condition, how advanced it is, and how the body responds. Ursodiol works best as part of a broader care plan with regular follow-up and liver function tests.
As with any medication, ursodiol may cause side effects. Your healthcare provider will discuss the potential benefits and risks before treatment and will adjust your care plan as needed.
BENEFITS
The most direct benefit is less bile buildup in the liver. When bile moves more freely, liver cells face less strain and less bile acid-related injury.
Ursodiol can improve liver enzyme levels and other liver test results. Your provider checks these results regularly to see how well treatment is working and whether your plan needs to change.
In primary biliary cholangitis, ursodiol delays scarring and other changes in liver tissue. This helps preserve liver function over time, especially when you take it consistently.
Ursodiol is an established first-line treatment for PBC. Current clinical guidance recommends it for people with abnormal liver enzyme values, regardless of disease stage. How much it helps varies from person to person.
Your healthcare provider will discuss the potential benefits and risks before treatment and provide ongoing support, including liver function monitoring, to ensure safe use. Tell your provider about any side effects that bother you or do not go away.
SUPPORTING YOUR TREATMENT
Ursodiol works best as part of a broader plan. Healthy daily habits and regular follow-up are an important part of care alongside the medication.
These habits can support how your body responds to treatment and may help protect your liver over time.

Common questions
Ursodeoxycholic acid (ursodiol) is a prescription medication used to treat certain cholestatic liver diseases, especially primary biliary cholangitis (PBC). These are conditions in which bile does not flow well through the liver and bile ducts. Your healthcare provider may prescribe Actigall, Urso, or Ursofalk if impaired bile flow is injuring your liver. Ask your provider whether ursodiol fits your diagnosis and care plan.
Take ursodiol exactly as your healthcare provider directs, usually by mouth with food. The typical dose is 13–15 mg per kilogram of body weight per day, divided into two to four doses. It comes as capsules, tablets, and, in some regions, an oral suspension. Your provider sets your dose based on your weight, liver condition, and response, so ask them if you have questions.
Ursodiol is generally a long-term, often lifelong treatment for PBC and many other chronic cholestatic liver diseases. Continued therapy helps maintain bile flow, preserve liver function, and slow disease progression. Do not stop taking it on your own, even if you feel well. If you are concerned about taking a medicine for years, talk with your healthcare provider about your long-term plan.
Common side effects include diarrhea, abdominal discomfort, nausea, headache, and weight gain. Not everyone has them. Your healthcare provider will monitor your liver function tests and your response to treatment while you take ursodiol. Tell your provider about any side effect that bothers you or does not go away, and ask about the benefits and risks before you start.
Your healthcare provider checks how well ursodiol is working with liver function tests, including liver enzyme levels. For PBC, the response is usually assessed about 12 months after you start. A good response is linked with better long-term outcomes. Results vary from person to person, so keep your follow-up appointments and ask your provider what your results mean for you.
Your provider may add or switch to another medicine. If liver tests stay abnormal after adequate ursodiol treatment, second-line options for PBC include obeticholic acid (Ocaliva), and fibrates may be considered off-label. Both are discouraged in people with decompensated liver disease. Your healthcare provider decides which option, if any, is right for you.
