Urso FAQ

Can Urso be used to prevent gallstone formation in people who have never had stones?

Urso is approved for the dissolution of existing small cholesterol gallstones, not for primary prevention. Lifestyle measures such as a balanced diet and maintaining a healthy weight remain the main strategies for reducing gallstone risk.

How long does it usually take to see improvement in itching during intra-hepatic cholestasis of pregnancy?

Many patients report a reduction in pruritus within 1-2 weeks of starting therapy, but individual response times can vary. Ongoing monitoring of bile-acid levels helps guide treatment duration.

Are there any visible differences between the 150 mg and 300 mg Urso tablets?

Both strengths are white, round tablets, but the 300 mg tablets are typically larger in diameter. Imprint codes and packaging details are listed on the product label for verification.

Will taking Urso affect routine blood tests for cholesterol?

Ursodeoxycholic acid can modestly lower serum cholesterol levels, particularly LDL cholesterol. This effect is generally considered beneficial but should be noted when interpreting lipid panels.

Is it safe to combine Urso with over-the-counter antacids?

Aluminium- or magnesium-containing antacids do not significantly affect UDCA absorption. However, it is advisable to separate dosing by at least 2 hours to minimise any potential interaction.

Can Urso be taken on an empty stomach?

While Urso can be absorbed without food, taking it with a meal improves tolerability and may enhance bioavailability. Consistency in timing (with or without food) helps maintain steady drug levels.

What should a traveler know about Urso and airport security?

Urso tablets are permitted in both carry-on and checked luggage. Keep the medication in its original packaging with a clear label, and carry a copy of the prescription or a doctor’s note if required.

Does Urso have any impact on liver transplant eligibility?

In patients with PBC, UDCA can slow disease progression, potentially delaying the need for transplantation. However, eligibility for transplant is determined by a comprehensive clinical assessment, not solely by medication use.

Are there any known interactions between Urso and herbal supplements such as milk thistle?

No robust data confirm a clinically significant interaction, but both agents affect liver metabolism. Patients should disclose all supplements to their clinician to ensure safe co-administration.

How does the cost of Urso compare with generic ursodeoxycholic acid in the UK?

Urso, as a branded product, is generally priced higher than unbranded generic UDCA tablets. Pricing varies by pharmacy and NHS prescribing status; patients can discuss cost-effective options with their prescriber.

Urso: Digestive Health Overview

Urso is a branded medication that contains Ursodeoxycholic Acid as its active component. It is classified as a digestive-health agent and is available in pill form in strengths of 150 mg and 300 mg. In the United Kingdom, Urso is a prescription-only medicine (POM) regulated by the Medicines and Healthcare products Regulatory Agency (MHRA). It is primarily prescribed for conditions involving impaired bile flow, such as primary biliary cholangitis and certain types of gallstones.

How Urso Works in the Body

Ursodeoxycholic Acid (UDCA) is a naturally occurring bile acid that modifies the composition and flow of bile. Its key actions include:

  • Reduction of Cholesterol Saturation - UDCA replaces more toxic, cholesterol-rich bile acids, helping dissolve cholesterol-based gallstones.
  • Cytoprotective Effect - It stabilises hepatocyte (liver cell) membranes, reducing injury from toxic bile acids.
  • Improved Bile Secretion - By stimulating bile flow, UDCA lowers the concentration of bile acids that can damage the liver and bile ducts.
  • Anti-Inflammatory Influence - It modulates immune activity within the bile ducts, slowing disease progression in primary biliary cholangitis.

These mechanisms collectively improve liver function and promote the clearance of abnormal bile constituents.

Conditions Treated by Urso

Urso is approved in the UK for the following indications:

  • Primary Biliary Cholangitis (PBC) - a chronic autoimmune disease that damages the small bile ducts.
  • Dissolution of Small Cholesterol Gallstones - when surgical removal is not preferred or feasible.
  • Intra-hepatic Cholestasis of Pregnancy (ICP) - to reduce maternal itching and improve fetal outcomes (used under specialist supervision).

In clinical practice, it may also be prescribed for other cholestatic liver disorders, but such use should follow specialist guidance.

Patient Suitability and Contraindications

Who Should Use Urso?

  • Adults diagnosed with PBC, cholesterol gallstones, or ICP.
  • Patients whose liver function tests (LFTs) indicate cholestasis without mechanical obstruction.
  • Individuals who can tolerate oral medication and have no known hypersensitivity to UDCA.

Absolute Contraindications

  • Known hypersensitivity to ursodeoxycholic acid or any tablet excipients.
  • Complete biliary obstruction (e.g., gallstone blockage of the common bile duct) without prior surgical or endoscopic relief.
  • Severe, decompensated liver failure (e.g., Child-Pugh C).

Relative Contraindications & Special Populations

  • Pregnancy: UDCA is classified as a Category B medicine in the UK; it may be used in ICP when benefits outweigh potential risks.
  • Breast-feeding: Limited data; use only if clearly needed.
  • Renal Impairment: No dose adjustment required, but monitor overall health.
  • Elderly: Start at the lower end of the dosing range and titrate cautiously.

Safety Profile: Side Effects and Interactions

Common Side Effects

  • Mild gastrointestinal upset (nausea, dyspepsia) - often transient.
  • Diarrhoea - usually resolves with continued therapy.
  • Fatigue or headache - reported in a minority of patients.

Serious Adverse Events

  • Worsening liver enzyme elevations or jaundice - requires prompt medical review.
  • Acute pancreatitis - rare but serious; seek emergency care if severe abdominal pain occurs.
  • Allergic reactions (rash, itching, swelling) - discontinue and seek medical advice.

Drug Interactions

  • Cholestyramine or other bile-acid sequestrants - bind UDCA and markedly reduce its absorption. Separate dosing by at least 4 hours.
  • Warfarin - UDCA may potentiate anticoagulant effects; monitor INR more frequently.
  • Oral contraceptives - possible alteration in hormone levels; clinicians should assess individual risk.

Food and Lifestyle Interactions

  • Take Urso with a meal or snack to improve absorption.
  • No specific alcohol restriction, but excessive intake can worsen liver disease.
  • No known effect on driving or use of machinery.

How to Take Urso

  • Standard Dosing: The usual adult dose is 13-15 mg/kg per day, divided into two or three doses. For a 70 kg adult, this corresponds to approximately 900-1050 mg daily.
  • Using Available Strengths: Urso tablets are supplied as 150 mg and 300 mg. A typical regimen might involve taking three to four 300 mg tablets daily, or an equivalent combination of 150 mg tablets, depending on the prescribed total dose.
  • Administration: Swallow tablets whole with water; do not crush or chew.
  • Missed Dose: Take the missed dose as soon as remembered unless it is near the time of the next scheduled dose. Do not double up.
  • Overdose: Symptoms may include severe diarrhoea, abdominal pain, and jaundice. Seek emergency medical attention; supportive care is the mainstay of treatment.
  • Discontinuation: Do not stop abruptly without consulting a healthcare professional, especially in PBC, as disease activity may rebound. A gradual taper may be advised.

Dosing must be individualized by a prescribing clinician based on body weight, disease severity, and treatment response.

Monitoring and Follow-Up

  • Liver Function Tests (ALT, AST, ALP, bilirubin): Baseline and then every 3-6 months during therapy.
  • Cholesterol Levels: May improve; monitor if hyperlipidaemia is a concern.
  • Pregnancy Monitoring: In ICP, fetal ultrasound and bile acid measurements are recommended as per obstetric guidelines.
  • Clinical Review: Assess symptom relief, side-effect burden, and adherence at each visit.

Storage and Handling

  • Store Urso tablets at room temperature (≤ 30 °C), protected from moisture and direct sunlight.
  • Keep the container tightly closed and out of reach of children.
  • Do not use tablets after the expiry date printed on the pack.
  • Dispose of unused medication via a pharmacy take-back program or according to local waste-disposal regulations.
