How Ursodiol works
Ursodiol is a bile acid that helps prevent and dissolve certain gallstones. It works by lowering how much cholesterol your gut absorbs and how much cholesterol your liver releases into bile. This helps lower cholesterol in bile and dissolve gallstones.
For primary biliary cholagitis (PBC), ursodiol helps replace harmful bile acids in the liver. It also helps protect liver and bile duct cells from damage.

Pros and cons of Ursodiol
Pros

- Tablets can be used long term to treat PBC
Cons
- Doesn't works for all types of gallstones
- Might need to be taken up to 4 times a day, depending on why you're taking it
Pharmacist tips for Ursodiol
- For ursodiol capsules: Swallow the capsules whole. Take your doses with or without food, at around the same times each day.
- For ursodiol tablets: Take with food at about the same times every day. You can split scored tablets in half if needed. Swallow the half-tablet right away with water because it can taste bitter. Keep the unused half at room temperature for up to 28 days, away from whole tablets.
- Tell your prescriber and pharmacist about all the medications you take. Some medications can make ursodiol work less well. These include cholestyramine (Prevalite), colestipol (Colestid), and antacids that contain aluminum, like some Mylanta products. Certain birth control pills and estrogen can also affect how well ursodiol works. Your care team can check if your medications are safe to take together.
- Keep your appointments for blood tests and other checkups. Your prescriber will check your liver function periodically during treatment. This helps check that ursodiol is still safe for you to take. And if you take the capsules to dissolve gallstones, you'll usually need regular ultrasounds every 6 months during the first year. This helps see how well ursodiol is working.
- If you're pregnant or plan to become pregnant: Talk to your prescriber before taking ursodiol. Studies haven't shown a higher risk of harm to unborn babies. To be safe, your prescriber can help you weigh the risks and benefits of taking ursodiol during pregnancy.
- If you're breastfeeding or plan to breastfeed: Tell your prescriber. Only small amounts of ursodiol pass into breast milk, so it isn't expected to harm to your baby. Your prescriber can help decide if it's safe for you to take.
Risks and warnings for Ursodiol
Ursodiol can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Abnormal liver function tests
Ursodiol hasn't been linked to liver damage. But your prescriber will still check your liver function before and during treatment. These blood tests help watch for signs of worsening liver problems.
Tell your care team right away if you notice yellowing of your skin or eyes, dark urine, unusual tiredness, or stomach pain. These could be signs that your liver isn't working well.
Intestinal stones and bowel blockage
- Risk factors: People with medical conditions that narrow the intestines or slow down digestion (e.g., Crohn's disease) | Have had certain bowel surgeries
In rare cases, people who took ursodiol developed stones in their intestines. These have somtimes caused a bowel blockage that might need surgery. The risk is higher in people with conditions that narrow the intestines or slow digestion, such as Crohn's disease. People who've had certain bowel surgeries might also be at higher risk.
Stop taking ursodiol and get medical help right away if you have severe stomach pain, bloating, or vomiting. These could be signs of a bowel blockage. Your care team can check if it's safe for you to keep taking ursodiol.
