What Holudexan is and what it is used for

Ursodeoxycholic acid, the active substance in Holudexan, is a naturally occurring bile acid that is found in small amounts in human bile.

Holudexan is used for:

dissolution of radiolucent cholesterol gallstones with a diameter of no more than 15 mm in patients with preserved gallbladder function, regardless of the presence of gallstones;

treatment of inflammation of the stomach lining (gastritis) caused by bile acid reflux;

treatment of primary biliary cirrhosis (from chronic inflammation of the bile ducts to liver cirrhosis) in patients without decompensated liver cirrhosis (diffuse, chronic liver disease, at a stage when the disease-related reduced liver function cannot be compensated).

2. What you need to know before you take Holudexan

Do not take Holudexan

if you are allergic (hypersensitive) to ursodeoxycholic acid or to any of the other ingredients of this medicine (listed in section 6); if you suffer from acute inflammation of the gallbladder or bile ducts; if you have a biliary obstruction (blockage of the common bile duct or the duct leading to the gallbladder);

if you suffer from frequent colic pains in the upper abdomen (biliary colic) your doctor has told you that you have calcified gallstones; if you suffer from impaired contractility of the gallbladder; Please ask your doctor if any of the conditions listed above apply or have applied to you in the past.

Warnings and precautions

Talk to your doctor or pharmacist before taking Holudexan. Holudexan should be taken under medical supervision.

Regular medical follow-up of your liver function tests is required every 4 weeks during the first 3 months of treatment and once every 3 months thereafter.

When used to dissolve gallstones, it is necessary for your doctor to order a scan of your gallbladder after the first 6-10 months of treatment.

If you are a woman and taking Holudexan to dissolve gallstones, you must use an effective non-hormonal method of contraception, as hormonal contraceptives may stimulate the formation of gallstones.

When used to treat primary biliary cirrhosis, worsening of symptoms (eg, pruritus) has rarely been observed at the start of treatment. In this case, talk to your doctor about reducing the initial dose.

Tell your doctor immediately if you have diarrhoea, as this may require a dose reduction or discontinuation of Holudexan.

Other medicines and Holudexan

You should tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.

The effects of these medicines may be changed (drug interactions).

When taking Holudexan, it is possible to weaken the effects of the following drugs:

colestyramine, colestipol (to lower blood lipids) or antacids (medicines that bind to stomach acids) containing aluminum hydroxide and/or aluminum oxide, eg smectite. If you are taking a medicine containing any of these active substances, it should be taken at least 2 hours before or after Holudexan;

ciprofloxacin, dapsone (antibiotics), nitrendipine (used to treat high blood pressure) and other medicines that are metabolised in a similar way. Your doctor may need to adjust the dose of these medications.

When taking Holudexan, a change in the effects of the following drugs is possible:

cyclosporine (a medicine that suppresses the immune system). If you are being treated with cyclosporine, it is necessary for your doctor to check its amount in your blood and, if necessary, adjust its dose;

rosuvastatin (a medicine to lower high blood cholesterol).

If you are taking Holudexan to dissolve gallstones, please tell your doctor if you are also taking medicines containing estrogen (eg birth control pills) or certain cholesterol-lowering medicines containing eg clofibrate.

These drugs can stimulate the formation of gallstones and counteract the effects of Holudexan in dissolving gallstones.

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines, including those obtained without a prescription.

Treatment with Holudexan may still be indicated. Your doctor will make the right decision for your condition.

Pregnancy, lactation and fertility

If you are pregnant or breast-feeding, think you may be pregnant or are planning to become pregnant, ask your doctor or pharmacist for advice before using this medicine. Holudexan can be used during pregnancy only after a careful assessment by the attending physician of the benefit/risk ratio.


There are no or limited data from the use of ursodeoxycholic acid in pregnant women. Animal studies show that growth and development of the baby may be impaired. Holudexan should not be used during pregnancy unless your doctor considers it absolutely necessary.

Women with childbearing potential

Even if you are not pregnant, you should discuss this treatment option with your doctor, as women of childbearing age should only be treated with Holudexan if they are using a reliable method of contraception. Non-hormonal contraception or low-estrogen oral contraceptives are recommended. If you are taking Holudexan to dissolve gallstones, however, you should only use effective non-hormonal contraceptive measures, as hormonal contraceptives can stimulate the formation of gallstones.

Before starting treatment, your doctor will rule out an existing pregnancy.


There are only a small number of documented cases of ursodeoxycholic acid use in nursing women. The levels of ursodeoxycholic acid in breast milk are very low and probably no adverse reactions can be expected in the infant.


Animal studies have shown no effect of this drug on fertility. There are no data on the effect of this drug on human fertility.
