Urso (Ursodiol) — Patient Information

Urso contains ursodiol (also known as ursodeoxycholic acid). It is used to treat certain bile-related liver and gallbladder conditions by helping improve bile composition and protecting bile ducts.

This guide is written for patients in the United Kingdom and explains how Urso works, how it is usually taken, key safety points, and practical advice to help you use it effectively.

Quick overview

• Active ingredient: Ursodiol (ursodeoxycholic acid)
• Uses: Some types of gallstones; specific bile duct/liver conditions
• How it works: Changes bile composition and helps dissolve certain cholesterol stones
• Typical dosing: Depends on the condition; often taken in divided doses with regular timing
• Common side effects: Generally mild; may include diarrhoea or stomach discomfort

What is Urso?

Urso is a medicine used for disorders involving bile flow and bile acids. Ursodiol is a naturally occurring bile acid present in smaller amounts in the human body; at medicine doses, it helps alter how bile behaves in the liver and gallbladder.

In the UK, Urso products are commonly supplied in different strengths and presentations depending on manufacturer and formulation. Your pack label or pharmacy advice will confirm the exact strength you have.

Mechanism of action (how it works)

Ursodiol works mainly in the bile system:

• Dissolves cholesterol gallstones (for appropriate stones): It reduces cholesterol saturation in bile and gradually helps stones shrink and dissolve.
• Improves bile flow and bile composition: It may promote healthier bile acid profiles, making bile less “harsh” to bile ducts.
• Protects liver cells and bile duct lining: It can help reduce bile acid–related injury to the cells lining the biliary tract.
• Supports bile duct function in certain cholestatic conditions: In some disorders, ursodiol helps improve biochemical markers and, in certain patients, symptoms.

Important: Urso is most effective for specific types of gallstones (typically cholesterol stones that are small and non-calcified). It does not work for all gallbladder problems.

Pharmacokinetics (what the body does with it)

Pharmacokinetics explains how ursodiol is absorbed, processed, and eliminated.

• Absorption: Ursodiol is absorbed in the small intestine. Fat intake and bile availability can influence absorption.
• Distribution: It circulates in blood and is taken up by the liver, where it becomes part of bile.
• Metabolism: It undergoes metabolic transformations in the liver and gut; a portion may be converted to related bile acids.
• Elimination: It is eliminated mainly through the digestive tract (bile). Small amounts are cleared via urine.

Because ursodiol is processed through the liver–bile system, conditions affecting bile flow (for example, severe bile blockage) can influence how well it works.

What is Urso used for? (indications)

Urso is used for selected liver and gallbladder conditions. Your healthcare professional will select the appropriate use based on diagnosis, imaging results, and liver tests.

1) Gallstones

• Dissolution of cholesterol gallstones in a functioning gallbladder, when surgery is not suitable or is being avoided.
• Best results are generally seen in patients with small, radiolucent (non-calcified) cholesterol stones.

2) Primary biliary cholangitis (PBC)

• Primary biliary cholangitis (formerly known as primary biliary cirrhosis) is a key long-term use in specialist care.

3) Other cholestatic conditions (specialist-led)

Depending on individual circumstances, ursodiol may be used for other bile-related disorders. Always follow the treatment plan set by your clinician.

When to take Urso (timing and routine)

How you time ursodiol can affect consistency and effectiveness.

• Common approach: Take ursodiol regularly at the same times each day.
• Divided dosing: Many regimens are split across the day (for example morning and evening) to maintain steady bile acid levels.
• With food: Taking with meals can help some people achieve better absorption and reduce stomach discomfort.

Practical tip: If you forget a dose, take it when you remember unless it is close to the next dose. Do not take a double dose to make up for a missed one.

Food interactions

Ursodiol absorption can be influenced by bile and fat digestion. Food does not usually make ursodiol dangerous, but it can affect how well it works for some patients.

• Take with meals if advised: This is often recommended for comfort and may support absorption.
• Maintain consistency: Try to keep your meal pattern similar day-to-day.
• If your diet is very low in fat: Discuss with your clinician/pharmacist—your absorption and bile response may differ.

If you have dietary restrictions due to liver or gallbladder disease, seek personalised advice rather than changing diet abruptly.

Alcohol interactions

Alcohol can affect the liver and may worsen liver inflammation in some people. There is not always a single “direct” interaction between alcohol and ursodiol, but prudence is advised—particularly in conditions like PBC or other cholestatic liver diseases.

• Avoid heavy or binge drinking: This increases liver stress and can make symptoms and liver tests less predictable.
• Talk to your clinician: If you drink regularly, ask for tailored guidance based on your liver function results.

If you are unsure whether alcohol is appropriate for your specific condition, a pharmacist or clinician can provide safer, personal advice.

Medicine interactions

Some medicines can interfere with ursodiol’s absorption or effect, or may be used alongside it with careful monitoring.

Medicines that bind bile acids (may reduce ursodiol effect)

Bile acid sequestrants can bind bile acids in the gut and may reduce ursodiol absorption.

• Examples: cholestyramine, colestipol, colesevelam

Management: If you take these, your clinician may adjust timing (often spacing doses by several hours) or select alternatives.

Other lipid-lowering or liver-related medicines

Some medicines used for cholesterol or liver conditions may change bile composition or require monitoring. Do not start or stop medicines without advice.

Interactions requiring monitoring

Ursodiol may also interact with medicines processed by the liver. While many combinations are possible, your healthcare professional may monitor liver enzymes and symptoms when treatment changes.

What you should do

• Tell your pharmacist about all medicines you take, including herbal products and supplements.
• Keep an up-to-date list for appointments.
• Do not “trial” new supplements without checking—some can affect the liver.

Dosing (how much to take)

Your exact dose depends on your diagnosis, severity, and response (including liver blood tests). Always follow the dosing instructions on your medicine label or as advised by your clinician.

Typical dosing ranges (general guidance): Ursodiol dosing in adults often falls within the range of 5 to 15 mg per kg per day, split into one or more doses. For PBC, dosing is commonly around 13–15 mg/kg/day in divided doses, but individual plans vary.

How dosing is usually arranged

• Divided doses: Often taken in two or more portions across the day.
• With food: Frequently advised for comfort and consistency.
• Review over time: Response is assessed via clinical symptoms and blood tests; gallstone dissolution can take months to longer.

Children

Use in children is specific and should only be done under specialist guidance and age/weight-based dosing.

If you have kidney impairment: Usually no major adjustment is required, but your clinician may monitor you depending on your overall health and liver function.

How long does Urso take to work?

Time to benefit depends on the condition:

• Gallstones: May take months or longer to shrink or dissolve. Not all stones respond.
• PBC: Improvement in liver blood tests may occur over months; long-term treatment is often needed.

It’s normal for treatment to feel slow. Regular monitoring helps ensure you are getting the expected benefit.

Safety profile (side effects and precautions)

Most people tolerate ursodiol well. Side effects are often mild and may improve with time or dose adjustment as advised by your clinician.

Common side effects

• Diarrhoea or loose stools
• Stomach upset, nausea, or mild abdominal discomfort

Less common effects

• Headache
• Skin reactions (uncommon)
• Transient changes in liver blood tests (usually monitored)

Seek urgent medical advice if

• Signs of an allergic reaction such as swelling of the face/lips, severe rash, or breathing difficulties
• Severe or persistent abdominal pain, especially with fever or yellowing of the skin/eyes that worsens
• Significant worsening jaundice or very dark urine/light stools

Special precautions

• Bile duct blockage: If bile flow is severely blocked, ursodiol may not work as expected and complications may occur—this requires specialist guidance.
• Monitoring: For long-term liver conditions, regular liver function tests are usually part of care.
• Pregnancy and breastfeeding: If you are pregnant, trying to conceive, or breastfeeding, discuss risks and benefits with a clinician.

Note: This information is not a substitute for personalised advice. Your prescriber and pharmacist can help assess your individual risk.

Practical use tips

• Stick to a routine: Choose times that fit your day (for example with breakfast and dinner).
• Don’t change dose yourself: If side effects occur, contact your pharmacy or clinician before adjusting.
• Monitor symptoms: For gallstone treatment, watch for persistent pain or signs of obstruction; for PBC, track fatigue and itch if present.
• Keep follow-up appointments: Blood tests and imaging guide whether the treatment is working.
• Hydration and diarrhoea: If you get mild diarrhoea, drink fluids; if it is persistent or severe, seek advice.
• Keep a medication list: Helps when reviewing interactions at appointments.

Alternative options

Alternatives depend on the underlying condition. For gallstones and PBC, options may include different medicines or procedures.

For gallstones

• Watchful waiting when symptoms are absent or mild (case-dependent).
• Surgery (e.g., cholecystectomy) for symptomatic gallstones or when dissolution is unlikely.
• Other approaches may be considered by specialists based on stone type and risk factors.

For primary biliary cholangitis (PBC)

• Other bile-acid related therapies and long-term specialist treatment plans
• Second-line options if ursodiol response is inadequate (decided by hepatology specialists)

Important: Switching or stopping ursodiol should only be done with medical advice. Treatment choices depend on your diagnosis, lab results, and risk factors.

UK market and legal context (what to expect)

In the United Kingdom, medicines are regulated by the Medicines and Healthcare products Regulatory Agency (MHRA) and follow prescribing and supply rules depending on legal classification and formulation.

Online pharmacies typically supply medicines according to UK medicines legislation and may require clinical checks or eligibility confirmation where necessary.

For Urso specifically, availability may vary by strength and formulation. Your chosen online pharmacy should provide clear information on supply, delivery times, and any service steps required to fulfil an order safely and legally.

Recent guidance and monitoring approach

For long-term liver conditions such as PBC, current clinical practice emphasises:

• Regular monitoring of liver blood tests (commonly including ALP, bilirubin, and other markers)
• Assessing treatment response over defined time points
• Escalation to additional therapies if response is inadequate, guided by hepatology specialists
• Managing symptoms such as itch and fatigue alongside disease control

Because recommendations can evolve, your clinician may reference up-to-date national or international guidance while tailoring treatment to you.

Delivery and availability in the UK

Availability of Urso may depend on the manufacturer, strength, and formulation. Online pharmacies in the UK often offer:

• Standard delivery to UK addresses (timing varies by supplier and stock status)
• Dispatched from local or central fulfilment centres
• Tracking information for many orders

To avoid delays, make sure your delivery address is correct and allow for weekends and public holidays. If the specific strength or pack size you need is temporarily out of stock, the pharmacy may offer an alternative product where appropriate.

Storage: Follow the instructions on the pack. In general, medicines should be stored at room temperature, away from moisture and direct heat, and kept out of reach of children.
