Patient Medication Information: uses, side effects, how to take - Urso
What is Urso and Urso DS used for?
- URSO or URSO DS is used to manage cholestatic liver disease.
How does Urso and Urso DS work?
URSO and URSO DS contain ursodiol (ER-so-DYE-all), which is a naturally occurring bile acid found in small quantities in normal human bile.
Cholestatic liver disease is caused when the release and flow of bile through the bile ducts from your liver are reduced. By taking URSO or URSO DS the amount of ursodiol in the bile increases, changing the make-up of the bile and causing an increase in bile flow. Ursodiol also works by replacing toxic bile acids that can destroy liver tissue.
What are the ingredients in Urso and Urso DS?
Medicinal ingredients: ursodiol
Non-medicinal ingredients: carnauba wax, dibutyl sebacate, ethylcellulose aqueous (cetyl alcohol, ethylcellulose, hydrogen peroxide, sodium lauryl sulfate), hydroxypropyl methylcellulose, magnesium stearate, microcrystalline cellulose, polyethylene glycol, povidone, and sodium starch glycolate.
Urso and Urso DS comes in the following dosage forms:
Tablets; 250 mg and 500 mg
Do not use Urso and Urso DS if you:
- have an allergy to ursodiol or to any ingredient in the formulation.
- have blockage of bile flow due to widespread liver disease.
- have complete blockage of bile flow due to disease outside of the liver.
To help avoid side effects and ensure proper use, talk to your healthcare professional before you take Urso or Urso DS. Talk about any health conditions or problems you may have, including if you:
- have taken URSO or URSO DS before and it was not well-tolerated or caused an allergy.
- have liver problems, or are in need of a liver transplant.
- have a partial blockage of bile flow due to disease outside of the liver.
- have variceal bleeding (bleeding from swollen veins, arteries, or lymph vessels).

Other warnings you should know about:
Laboratory tests: Your healthcare professional may do certain tests during your treatment. These include liver function tests and bilirubin levels every month for three months after start of treatment, and every six months thereafter.
Bezoars in Patients with a Risk for Blockage in the Gut (intestine): A bezoar is where material builds up in the stomach or gut, causing a blockage. This can cause symptoms such as nausea, vomiting, and pain in the belly area. Bezoars may cause a blockage that requires surgery. This very rare side effect happened in patients who were taking URSO and had medical conditions that caused stomach or gut blockage (such as previous gut surgery or Crohn’s disease).
Tell your healthcare professional about all the medicines you take, including any drugs, vitamins, minerals, natural supplements or alternative medicines.
The following may interact with Urso and Urso DS:
- Medicines that reduce the amount of bile acids such as cholestyramine or colestipol
- Antacids that contain aluminum such as Rolaids, Maalox, Mylanta, and many others.
- Cyclosporine
- Dapsone
- Nitrendipine
How to take Urso and Urso DS:
- Take URSO and URSO DS for the full duration of treatment, even if you begin to feel better.
- To break URSO DS scored tablet easily, place the tablet on a flat surface with the scored section on top. Hold the tablet with your thumbs placed close to the scored part of the tablet (groove). Then apply gentle pressure and snap the tablet segments apart (segments breaking incorrectly should not be used). The segments should be swallowed unchewed, with water.
- To prevent leakage of the active medicinal ingredient (ursodiol) from the cut tablets onto the surface of whole tablets and spreading the bitter taste, it is recommended that cut tablets be stored separately from whole tablets.
- This medication should only be used as instructed by your healthcare professional. Follow your healthcare professional’s instructions. Do not change the dose or stop the treatment without your healthcare professional’s advice.
Usual dose:
Your healthcare professional would have prescribed the amount of URSO or URSO DS you should take each day for your medical condition. URSO and URSO DS should be taken in 2 to 4 divided doses with food. It is easier to remember to take your medication if it is taken at the same time each day. Setting up a routine to take your medication helps this activity become a normal part of your day.
Overdose:
The most severe symptom of overdosage would likely be diarrhea.
| If you think you, or a person you are caring for, have taken too much URSO or URSO DS, contact a healthcare professional, hospital emergency department, or regional poison control centre immediately, even if there are no symptoms. |
