Urso (Ursodiol) — Patient Guide (UK)

Urso contains ursodiol (also known as ursodeoxycholic acid). It is used to treat certain liver and bile-duct conditions. This guide explains what Urso is, how it works, how it’s typically taken, and what to watch for. If you have any concerns or changing symptoms, speak to a healthcare professional.

Quick facts

• Active ingredient: Ursodiol (ursodeoxycholic acid)
• What it’s used for: Certain types of bile-duct and gallbladder problems, and some liver conditions
• How it works: Helps bile become less irritating and supports bile flow
• Typical dosing: Depends on the condition; often taken in divided doses
• Common questions: When to take it, whether to take it with food, and possible interactions

Basic product information

Urso is a medicine used in adults and, in some cases, children under specialist supervision. The exact strength and formulation can vary by product presentation.

• Medicinal ingredient: Ursodiol
• Class: Bile acid preparation
• Forms: Usually tablets or capsules (depending on the specific Urso presentation)

Important: Always check the strength stated on the pack and follow the dosing instructions provided by your clinician or pharmacist for your particular condition.

How Urso works (mechanism of action)

Ursodiol is a naturally occurring bile acid that is present in small amounts in human bile. In medicine, it acts in several ways:

• Improves bile composition: It helps shift bile acid composition toward a less toxic profile, which may reduce irritation to the bile ducts and liver cells.
• Supports bile flow: It may help promote more effective flow of bile, reducing cholestasis (reduced bile flow).
• Protects liver cells: By reducing bile acid toxicity, it can help protect cells from damage caused by harmful bile acids.
• Helps dissolve certain cholesterol gallstones: For selected patients, it may gradually dissolve cholesterol-based gallstones by altering bile cholesterol saturation.

It’s normal for results (especially gallstone-related outcomes) to take time. Improvement depends on the underlying diagnosis and individual factors.

Pharmacokinetics (how the body handles it)

Pharmacokinetics describes how the body absorbs, distributes, metabolises, and eliminates the drug.

Absorption

• Ursodiol is absorbed in the small intestine.
• Absorption can vary depending on bile availability, intestinal function, and the presence of certain fats in the diet.

Distribution

• After absorption, ursodiol is incorporated into bile and circulates in an enterohepatic pathway (recycling via the liver and intestine).

Metabolism and excretion

• It is metabolised and transformed into bile acid derivatives.
• Overall elimination is mainly through the bile and faeces, with only a small amount excreted in urine.

Practical takeaway: Because ursodiol is closely linked to bile flow and gut handling, taking it regularly and as advised is important for effectiveness.

Typical use in the UK

Urso is used for specific bile-related conditions. The exact indication depends on your diagnosis. Common uses in clinical practice include:

• Primary biliary cholangitis (PBC): Often prescribed to improve liver function and slow progression in eligible patients.
• Dissolution of cholesterol gallstones: In carefully selected cases where gallstones are cholesterol-rich and suitable for medical dissolution.
• Other cholestatic liver/bile conditions: Depending on specialist assessment, it may be used for certain bile-duct or liver disorders.

Note: Urso is not suitable for all types of gallstones or all liver/bile conditions. Imaging and blood tests are used to identify whether it’s appropriate.

Indications (when Urso may be recommended)

In broad terms, ursodiol may be recommended when:

• You have a cholestatic liver or bile-duct condition (where bile flow is reduced and bile acids may be toxic to tissues).
• Your gallstones are cholesterol-type and meet criteria for medical dissolution (for example, when surgery is not suitable).
• A specialist determines ursodiol is likely to benefit your specific condition based on tests, imaging, and overall health.

If you are unsure why you were given Urso, ask your pharmacist or clinician. It’s helpful to know your diagnosis and what treatment goal is expected (e.g., improving liver markers, reducing bile duct inflammation, or dissolving stones).

How to take Urso (timing and dosing guidance)

Always follow the dose your healthcare professional gives you. Dosing may be weight-based and varies with the condition being treated.

Timing

• Urso is commonly taken once or twice daily depending on the prescribed regimen.
• For divided dosing, taking it with meals or at regular intervals can improve tolerability and consistency.
• Try to take it at the same times each day to maintain steady levels.

With or without food?

Many patients find it easier to take ursodiol with meals, though your prescriber/pharmacist may give specific instructions. Food can influence bile secretion and may affect how the medicine behaves in the gut.

What to do if you miss a dose

• If you remember soon after: take it as soon as you can.
• If it’s close to the next dose: skip the missed dose and continue with your usual schedule.
• Do not double up to make up for a missed dose.

Dosing (general information)

Urso dosing depends on the condition. Doses are commonly expressed in relation to body weight for some indications.

Important: The following is general guidance only. Your prescription labels and clinician instructions always take priority.

If you want, tell us your prescribed strength and dosing schedule (from your pack label), and we can help you understand how to fit it into your day—without changing your medical plan.

Food interactions and dietary considerations

Food can affect how bile acids work in the digestive system. Practical dietary tips include:

• Take consistently: If you’ve been advised to take Urso with food, keep doing so each day.
• Fat intake: Because bile acids help digest fats, a very low-fat or very high-fat diet may alter bile physiology. Don’t make major diet changes without guidance.
• Grapefruit and acidic drinks: There’s no common, well-established direct interaction with ursodiol specifically. However, always check for interactions with any other medicines you take.

Alcohol and ursodiol: See the section below. Liver conditions often mean alcohol should be limited or avoided; follow your healthcare professional’s advice.

Alcohol interactions

There is no single universally listed “direct” interaction between ursodiol and alcohol, but alcohol can affect the liver and bile system.

• If you have a liver condition being treated with Urso, it’s usually recommended to avoid alcohol or keep it to an absolute minimum.
• Alcohol can worsen liver inflammation in some people and may interfere with overall disease control.

Practical advice: If you’d like personalised guidance on alcohol for your specific diagnosis, ask your clinician or pharmacist.

Medicine interactions (important)

Certain medicines can interfere with bile acid absorption or the effectiveness of ursodiol. Always tell your healthcare professional about all medicines and supplements you use.

Medicines that may reduce effectiveness

• Bile acid sequestrants (used for cholesterol), such as:
  • cholestyramine
  • colestipol
  • colesevelam

These may bind bile acids in the gut and prevent ursodiol from being absorbed properly. If they are needed, your clinician may advise separating doses by several hours.

Other potential interactions to discuss

• Antacids containing certain components: discuss with your pharmacist if you use frequent antacids.
• Hormonal medicines or therapies affecting bile/cholesterol balance: if relevant, your clinician may monitor more closely.
• Cholesterol-lowering regimens: when combining therapies, monitoring may be needed.

Supplements and herbal products

• Some supplements can affect liver enzymes or digestion. Examples include high-dose herbal blends.
• Bring a list of supplements (or photos of labels) to your pharmacist for a quick review.

Action step: If you start any new medicine while taking Urso, it’s wise to check interactions.

Safety profile (what to expect and what to watch for)

Most people tolerate ursodiol well. However, like all medicines, it can cause side effects and may not be suitable for everyone.

Common side effects

• Stomach discomfort (indigestion, abdominal discomfort)
• Nausea
• Diarrhoea or looser stools
• Headache (occasionally reported)

Serious or urgent symptoms

Seek prompt medical advice if you experience:

• Signs of an allergy such as rash, swelling of lips/face, breathing difficulties
• Worsening jaundice (yellowing of skin/eyes)
• Severe abdominal pain, especially with fever or vomiting
• Unusual bleeding or bruising (could indicate liver-related problems)

Who should take extra care?

• People with advanced liver disease or complex bile duct problems
• People with a history of gallstone complications
• Those taking medicines that affect bile acid handling (as discussed above)

Your clinician may perform regular blood tests (commonly liver function tests) to monitor response and safety.

Practical use tips (getting the best from your treatment)

• Set reminders: Regular dosing helps achieve the intended benefit, especially in long-term liver conditions.
• Keep a symptom diary: If you notice diarrhoea, discomfort, or changes in symptoms, note timing relative to doses. This helps clinicians adjust the regimen if needed.
• Follow monitoring schedules: If your plan includes blood tests, attend them even if you feel well.
• Don’t stop early: Long-term conditions often require sustained treatment. Stopping suddenly can remove the protective effect.
• Check your product strength: Different strengths exist. Use the pack label to confirm you’re taking the correct number of tablets/capsules.

How long does Urso take to work?

Timing varies by indication:

• Cholestatic liver conditions: Improvement may be seen over weeks to months, with ongoing monitoring to assess response.
• Gallstone dissolution: It often takes many months for cholesterol stones to reduce in size or dissolve, and not everyone achieves complete dissolution.

Your clinician can explain what “success” means for your specific diagnosis and how it will be measured.

Alternative options

Alternative treatments depend on your underlying condition. Common alternatives include:

• For gallstones: surgical options (e.g., cholecystectomy) or other medical approaches may be considered based on stone type and suitability.
• For primary biliary cholangitis (PBC) and other cholestatic conditions: additional or alternative therapies may include medicines to reduce inflammation or improve bile flow, along with supportive measures.
• Supportive care: managing itching (if present), monitoring vitamin levels (especially fat-soluble vitamins where relevant), and lifestyle measures.

If you’re comparing options, ask your healthcare professional what alternatives are appropriate for your diagnosis and stage, and what risks and benefits differ from ursodiol.
