Primary biliary cholangitis is a chronic liver disease that progresses slowly over many years. While there is currently no cure for this condition, modern treatment approaches can help slow the damage to the liver and improve quality of life. Understanding the available treatment options — both those already approved and those being tested in research settings — is an important step for anyone living with this disease.

How Treatment Helps Manage a Lifelong Condition

When someone receives a diagnosis of primary biliary cholangitis, commonly called PBC, the main goal of treatment is to protect the liver from further damage. This disease causes ongoing inflammation in the small tubes inside the liver called bile ducts, which normally carry a digestive fluid called bile. Over time, this inflammation can destroy these ducts, causing bile to back up and harm liver tissue.^[1][2]

Treatment cannot reverse damage that has already occurred, but it can slow down how quickly the disease gets worse. The approach to treatment depends on several factors, including how early the disease was caught, how a person’s body responds to initial medications, and whether any complications have developed. Some people have no symptoms when they are first diagnosed, while others may experience fatigue, itchy skin, or other problems that also need attention.^[3][5]

Medical societies and liver specialists have developed guidelines to help doctors choose the best treatments for each patient. These recommendations are based on years of research and experience with thousands of patients. The field continues to evolve as scientists work to develop new therapies that might work better or help those who don’t respond well to current options.^[4][7]

Standard Medical Treatment for Primary Biliary Cholangitis

The foundation of PBC treatment has been the same medication for many years: ursodeoxycholic acid, often shortened to UDCA or sometimes called ursodiol. This is usually the first medicine prescribed to nearly everyone diagnosed with PBC, regardless of what stage the disease has reached. UDCA is a naturally occurring bile acid that helps improve the flow of bile through the liver.^[11][13]

Doctors typically prescribe UDCA at a dose of 13 to 15 milligrams for each kilogram of a person’s body weight per day. Patients usually take this medication once daily or split into two doses. Once someone starts taking UDCA, they will likely need to continue it for the rest of their life. Research has shown that people who respond well to UDCA can have a life expectancy similar to people without PBC, which is why starting this treatment early is so important.^[14][15]

How well UDCA works varies from person to person. Studies suggest that the medication helps slow liver damage in most patients, particularly those who begin treatment in the early stages of the disease. It can improve blood test results that measure liver function and may delay the need for a liver transplant. However, it’s important to understand that UDCA does not cure PBC, and it typically does not improve symptoms like fatigue, even though it is protecting the liver.^[13][14]

After about one year of treatment with UDCA, doctors assess how well the medication is working. They do this by checking blood tests that measure liver enzymes, particularly one called alkaline phosphatase (ALP). If these levels have come down to near-normal ranges, the treatment is considered successful. Unfortunately, roughly 20 to 30 percent of people with PBC do not respond adequately to UDCA alone. These individuals are at higher risk for disease progression and may need additional treatment.^[15][7]

For patients who don’t respond well enough to UDCA alone, or who cannot tolerate it, additional options are available. Obeticholic acid (OCA) is a second medication that works differently from UDCA. It functions by improving bile flow and reducing inflammation in the liver. This medication may be prescribed either in combination with UDCA or on its own for people who cannot take UDCA.^[13][14]

Obeticholic acid starts at a low dose — typically 5 milligrams once daily — and may be increased to 10 milligrams after several months if the person tolerates it well. However, this medication can cause or worsen itching, which is already a common symptom in PBC. If itching becomes a problem, the doctor may lower the dose or prescribe additional medication to help manage the itch. People with very advanced liver disease or cirrhosis need to be especially careful with obeticholic acid, as it can sometimes make their condition worse.^[14][15]

Another treatment option that has become available more recently is elafibranor. This medication works by reducing the amount of bile acid the body produces and by making the bile that is produced less harmful to the liver. Like obeticholic acid, elafibranor can be used in combination with UDCA for people who don’t respond well enough to UDCA alone, or it can be used by itself for those who cannot take UDCA. Side effects may include constipation, diarrhea, headaches, and upset stomach.^[13]

Treating the Symptoms That Affect Daily Life

Beyond medications that slow liver damage, people with PBC often need treatment for specific symptoms that can significantly affect their quality of life. The two most common and troublesome symptoms are intense itching and overwhelming fatigue.^[2][6]

Itching, medically called pruritus, affects about 55 percent of people with PBC. This is not ordinary itching from dry skin. People describe it as a deep burning sensation under the skin that doesn’t improve with scratching — in fact, scratching usually makes it worse. The itching can be severe enough to interfere with sleep and daily activities. The first-line treatment for this symptom is a medication called colestyramine (also spelled cholestyramine).^[2][13]

Colestyramine comes as a powder in packets that must be mixed with water or juice. Because it has an unpleasant taste, mixing it with fruit juice often makes it more tolerable. People usually need to take it for several days before noticing improvement in their itching. One important consideration is timing: if someone is also taking UDCA or other medications, they need to separate these doses. Colestyramine should be taken at least one hour before or four to six hours after other medicines, because it can interfere with how the body absorbs them.^[13]

Constipation is a common side effect of colestyramine, though this usually improves as the body adjusts to the medication. Long-term use can affect the body’s ability to absorb certain vitamins from food — specifically vitamins A, D, K, and folic acid. For this reason, people taking colestyramine may need vitamin supplements, which a doctor can recommend.^[13]

If colestyramine doesn’t help the itching or if someone cannot tolerate it, alternative medications are available. An antibiotic called rifampicin has been found to help some people with itching, though how it works for this purpose isn’t entirely clear. Another option is naltrexone, a medication that affects how the brain processes certain signals. These alternatives are typically prescribed by liver specialists who have experience managing PBC.^[13]

Fatigue is the other major symptom, affecting about 65 percent of people with PBC. This is not the kind of tiredness that goes away after a good night’s sleep. People describe it as a profound exhaustion that can make even simple daily tasks feel overwhelming. Unfortunately, no medications have been specifically approved to treat fatigue in PBC, and UDCA doesn’t help with this symptom.^[2][12]

When someone reports severe fatigue, doctors first try to rule out other possible causes. Iron deficiency anemia, an underactive thyroid, sleep problems like sleep apnea, and depression can all cause fatigue and are treatable conditions. If these are addressed, the fatigue may improve. Some patients have found that medications used to treat excessive sleepiness, such as modafinil, or certain antidepressants, can help with PBC-related fatigue, though these are used off-label for this purpose.^[13][21]

Lifestyle approaches also matter for managing fatigue. Regular exercise, even in modest amounts, can actually increase energy levels over time. This might seem counterintuitive when someone is exhausted, but physical activity improves blood circulation and releases natural energy-boosting chemicals in the body. Starting small — perhaps with a 10-minute walk — and gradually increasing activity as tolerated can make a difference.^[13][18]

Managing Complications That Can Develop

As PBC progresses, particularly if it advances to cirrhosis, several complications can develop that require specific treatment. These include problems with cholesterol levels, bone health, and vitamin absorption.^[5][14]

High blood cholesterol is very common in PBC — more than half of patients develop elevated cholesterol levels. Interestingly, despite these high levels, people with PBC don’t seem to have an increased risk of heart disease from cholesterol. However, if treatment is needed, doctors may prescribe medications called statins and recommend lifestyle changes such as a heart-healthy diet and regular exercise.^[14]

Osteoporosis, or thinning of the bones, is one of the most common complications of PBC. The disease can interfere with the body’s ability to absorb calcium and vitamin D, both crucial for bone strength. This makes bones more fragile and increases the risk of fractures from falls. To prevent or treat osteoporosis, doctors may prescribe medications that slow bone loss and improve bone density. Supplements of calcium and vitamin D are also commonly recommended.^[5][14]

People with PBC often have low levels of fat-soluble vitamins — A, D, E, and K. This happens because when bile flow is impaired, the body cannot properly absorb fats and these vitamins that are carried in fats. Vitamin deficiencies can cause various problems: vitamin A deficiency affects vision, vitamin D deficiency weakens bones, vitamin E deficiency can affect nerves, and vitamin K deficiency increases bleeding risk. Doctors can test for these deficiencies and prescribe appropriate supplements with specific dosing instructions.^[5][14]

Some people with PBC also have Sjögren’s syndrome, another autoimmune condition that causes dry eyes and dry mouth. This requires regular eye and dental examinations to prevent complications. Artificial tears, special mouthwashes, and other supportive measures can help manage these symptoms.^[14]

If PBC progresses to cirrhosis and complications such as fluid buildup in the abdomen (ascites) or bleeding from swollen blood vessels in the digestive tract (varices) develop, these require additional specialized treatments. In some cases, a procedure called TIPS (transjugular intrahepatic portosystemic shunt) may be needed to reduce pressure in the blood vessels. In advanced cases where the liver is severely damaged and no longer functioning adequately, a liver transplant may become necessary.^[14][6]

Innovative Treatments Being Studied in Clinical Trials

Because current treatments don’t work for everyone and don’t address all aspects of PBC, researchers continue to search for new and better therapies. Clinical trials are research studies where new treatments are tested to determine if they are safe and effective. These trials progress through different phases, each designed to answer specific questions.^[15]

Phase I trials involve small numbers of participants and focus primarily on safety. Researchers want to know what dose of a new drug can be given safely and what side effects might occur. Phase II trials include more participants and begin to evaluate whether the treatment actually works — does it improve liver blood tests, reduce symptoms, or slow disease progression? Phase III trials are large studies that compare the new treatment directly against the current standard treatment to see if the new option is better, equivalent, or has different benefits.^[7]

Several types of therapies are being investigated in clinical trials for PBC. Some are variations or improvements on existing bile acid therapies. Researchers are testing different molecules that work on the same pathways as UDCA or obeticholic acid but might be more effective or have fewer side effects. These experimental treatments aim to improve bile flow, reduce inflammation, or protect liver cells from damage through various mechanisms.^[15]

Scientists are exploring the potential of immunotherapy approaches for PBC. Because PBC is an autoimmune disease — meaning the body’s immune system mistakenly attacks its own bile ducts — treatments that modify immune system activity could theoretically slow or stop the disease process. These might include medications that block specific immune system signals or cells that are driving the inflammation in the liver. This is a complex area of research because the immune system needs to remain functional to protect against infections while being calmed down enough to stop attacking the liver.^[1][5]

Another research direction involves studying molecules that target specific pathways involved in liver scarring, also called fibrosis. When the liver is repeatedly injured by inflammation, it forms scar tissue as part of its healing response. Unfortunately, too much scarring interferes with liver function. Drugs that could prevent or even reverse fibrosis would be tremendously valuable for people with PBC and other chronic liver diseases. Some clinical trials are testing medications specifically designed to interrupt the biological processes that lead to scar formation.^[7]

Several trials are focusing on better treatments for the symptoms of PBC, particularly itching and fatigue, which current therapies don’t adequately address. New anti-itch medications working through different biological pathways are being tested. Some target specific receptors in the nervous system, while others aim to reduce the substances in the blood that trigger the sensation of itch. Similarly, researchers are studying medications that might specifically address PBC-related fatigue by affecting energy metabolism or inflammation in ways that current drugs do not.^[15]

When considering a clinical trial, it’s important to understand that experimental treatments are, by definition, not yet proven. They might work better than current options, but they might not help or could potentially cause unexpected side effects. However, clinical trials are carefully designed and monitored to protect participants’ safety. Everyone in a trial receives close medical attention and frequent monitoring. Additionally, by participating, people contribute to advancing medical knowledge that could help future patients.^[7]

The Importance of Regular Monitoring and Follow-up

Once treatment for PBC begins, regular monitoring becomes a crucial part of managing the disease. This isn’t just about checking whether medications are working — it’s about catching any changes or complications early, when they’re easier to address.^[7][15]

People with PBC typically need blood tests every three to six months to monitor liver function. These tests measure various enzymes and substances that indicate how well the liver is working and whether inflammation and damage are being controlled. The most important marker is alkaline phosphatase, but doctors also check other liver enzymes, bilirubin levels (which can indicate more advanced disease), blood cell counts, and kidney function.^[15]

After starting or changing medication, doctors reassess the response after about one year. If blood test results have improved and come close to normal ranges, the treatment is working well. If results remain significantly abnormal despite treatment, it indicates the person is at higher risk for disease progression and may need additional therapies.^[7][15]

Imaging tests like ultrasound are also important. These are typically done every 12 to 24 months for people whose disease is well-controlled, but may be needed more frequently — such as every six months — for those at higher risk. Ultrasound can detect complications like liver cancer, evaluate liver size and texture, and help assess disease progression. More advanced imaging techniques like elastography (sometimes called FibroScan) or MR elastography can measure liver stiffness, which indicates how much scarring has occurred.^[7][11]

Beyond these specific tests, people with PBC should also be screened for other conditions that commonly occur alongside the disease. This includes thyroid problems, vitamin deficiencies, and osteoporosis. Women with PBC should continue routine breast cancer screening. Anyone with cirrhosis needs regular screening for liver cancer.^[5][14]
