1. What is Proursan and what is it used for
Ursodeoxycholic acid, the active substance of Proursan, is a naturally occurring bile acid. It is found in small amounts in the human body, in bile. Proursan is used:
- to dissolve cholesterol gallstones, resulting from excessive cholesterol accumulation in the gallbladder (in patients for whom surgical treatment is not possible), not visible in a standard X-ray examination (stones that are visible will not be dissolved), with a diameter not exceeding 15 mm. The gallbladder function should be preserved despite the presence of stones.
- to treat primary biliary cirrhosis of the liver, a disease that progresses with liver bile duct damage, leading to bile accumulation. This can cause liver scarring (liver cirrhosis). The liver should not be damaged enough to impair its normal function.
Children and Adolescents
- -in liver disease in the course of a disease called cystic fibrosis (fibrocystic disease) in children aged 6 to 18 years.
2. Important information before taking Proursan
When not to take Proursan
- if you are allergic to bile acids (such as ursodeoxycholic acid) or any of the other ingredients of this medicine (listed in section 6);
- if you have acute inflammation of the gallbladder and bile ducts;
- if you have a blockage of the common bile duct or the gallbladder duct (bile duct obstruction);
- if you experience frequent pain in the upper abdomen, resembling colic (episodes of biliary colic);
if you have calcified gallstones;
- if you have impaired gallbladder function;
- if you are a child with a diagnosed atresia (obstruction) of the bile ducts and insufficient bile flow, even after surgical intervention.
Warnings and precautions
Before starting to take Proursan, discuss it with your doctor or pharmacist. Proursan can only be taken under medical supervision. During treatment, the doctor should recommend regular monitoring of liver function parameters every 4 weeks for the first 3 months, and then every 3 months. If the medicine is used to dissolve gallstones, the doctor should perform an imaging examination of the gallbladder after the first 6-10 months of treatment. If you are taking Proursan to dissolve gallstones, you should inform your doctor about any medications you are taking that contain estrogen hormones, such as hormonal contraceptives, as these medications stimulate the formation of gallstones. In the case of treatment of primary biliary cirrhosis of the liver, in rare cases, worsening of symptoms may occur at the beginning of treatment. In such a situation, you should consult your doctor to reduce the initial dose.

Proursan can be used regardless of age. The use of Proursan depends on body weight and the type of disease.
