Ursofalk tablets, capsules and suspension contain the active ingredient ursodeoxycholic acid. 

What is it used for?

  • Dissolving gallstones that are mainly made up of cholesterol (radiolucent gallstones).
  • Treatment of primary biliary cirrhosis, which is a slowly progressive form of liver inflammation that starts around the bile ducts.

How does it work?

  • Ursofalk tablets, capsules and suspension contain the active ingredient ursodeoxycholic acid. Ursodeoxycholic acid is also available without a brand name, ie as the generic medicine.
  • Ursodeoxycholic acid is a chemical called a bile acid. It occurs naturally in bile and can be used to dissolve gallstones.
  • The liver produces bile, which is then stored in the gall bladder. Bile is released by the gall bladder to aid the digestion of fats. It consists of cholesterol dissolved within bile salts. Gallstones occur in the gall bladder as a result of too much cholesterol, or too few bile salts within the bile.
The imbalance causes excess cholesterol to separate out of the bile and form stones.
  • Ursodeoxycholic acid causes gallstones to dissolve by a mechanism that is not fully understood. It is known to reduce the production of cholesterol by the liver and also to reduce the absorption of cholesterol from the gut. Both of these actions decrease the amount of cholesterol that passes into the bile. Also, since ursodeoxycholic acid is a bile acid itself, it increases the level of bile acids within the bile.
  • The combination of these two factors reverses the imbalance and stops the cholesterol separating out of the bile. The gallstones then begin to dissolve. This is a useful alternative for people who cannot have, or wish to avoid surgery. Treatment is continued for up to two years, depending on the size of the stones. The medicine should be continued for three to four months after the stone has dissolved.
  • How do I take it?

    • Ursofalk tablets, capsules and suspension should be taken with or just after food.
    • The tablets and capsules should be swallowed with a glass of water.
    • The dose prescribed and how often the medicine needs to be taken depends on the condition being treated. It is important to follow the instructions given by your doctor. These will be printed on the dispensing label your pharmacist has put on the packet of medicine.
    • Following a low cholesterol diet may help to increase the effectiveness of this medicine. Your doctor or pharmacist can advise you on this.


    • Treatment with this medicine for gallstones may have to be continued for up to two years, depending on the size of the gallstones. You should have regular check-ups to see if the medicine is helping to dissolve the gallstones. Treatment with this medicine should be continued for three to four months after the gallstones have dissolved.
    • If you are taking this medicine for primary biliary cirrhosis you will need to have regular blood tests to monitor your liver function. These should be every four weeks for the first three months of treatment, then every three months during continued treatment.

    Not to be used in

    • Treating gallstones that have a high calcium content and show up on X-rays (radio-opaque calcified gallstones).
    • People with acute inflammation of the gall bladder or bile duct.
    • People with a blockage of the bile duct (biliary obstruction).
    • People who frequently experience pain with their gallstones (biliary colic).

    • Diarrhoea or pasty stools.

    Very rare 

    • Nettle-like rash.
    • Calcification of gallstones (a process in which the mineral calcium builds up in the gallstones causing them to harden). If this occurs it will stop this medicine dissolving the gallstones and surgery may then be needed to remove them.

    Frequency unknown

    • Itching.
    • Nausea and vomiting.

    The side effects listed above may not include all of the side effects reported by the medicine's manufacturer.

Similarly, check with your doctor or pharmacist before taking any new medicines while taking this one, to make sure that the combination is safe.

    Ursodeoxycholic acid can increase the absorption of the immunosuppressant medicine ciclosporin from the gut. People taking ursodeoxycholic acid together with ciclosporin should have the level of ciclosporin in their blood checked regularly. Your doctor may need to adjust your dose of ciclosporin.

    The following medicines can reduce the absorption of ursodeoxycholic acid from the gut and could make it less effective. These should not be taken at the same time as or within two hours of taking ursodeoxycholic acid:

    • antacids for heartburn or indigestion
    • charcoal
    • colestipol
    • colestyramine.
