What is Udiliv 300 used for?
Udiliv 300 is a prescription medicine. It is used, on a doctor's advice, to dissolve some gallstones and to treat primary biliary cholangitis, a long-term liver disease.
- Dissolving small to medium cholesterol-rich gallstones that look clear on X-ray, in people whose gallbladder still works
- Treating primary biliary cholangitis (also called primary biliary cirrhosis), a long-term liver disease
How does Udiliv 300 work?
Cholesterol-rich gallstones form when bile holds too much cholesterol. Ursodeoxycholic acid lowers the amount of cholesterol in bile, so small stones can slowly dissolve. The exact way it works is not fully understood.
What happens in your body after you take it
You swallow the tablet
The tablet dissolves in the gut and ursodeoxycholic acid is absorbed into the blood.
It goes to the liver
Blood carries it to the liver, which takes it up and sends it into the bile.
Bile contains less cholesterol
In the bile, ursodeoxycholic acid lowers the share of cholesterol, so the bile is less saturated with it.
Small stones can slowly dissolve
With less cholesterol in the bile, small cholesterol gallstones can slowly dissolve over many months. Stones that contain calcium or bile pigments do not.
The body clears it
It passes through the gut and leaves the body in the stool. Your doctor checks progress with scans and liver blood tests.
How to take Udiliv 300
Take Udiliv 300 exactly as your doctor has prescribed or as printed on the pack. The dose depends on body weight and the condition, and your doctor decides it and how long you need it.
- Swallow the tablet with water. Follow the label or your doctor's advice about timing; for gallstones it is sometimes taken at night.
- Treatment for gallstones can take many months. Do not stop on your own.
- If you miss a dose, take it when you remember. If it is almost time for the next dose, skip the missed one. Do not take two doses together.
- Your doctor will arrange liver blood tests and gallbladder scans during treatment.
- Keep a gap of at least 2 hours from antacids with aluminium and from colestyramine.
Side effects of Udiliv 300
The most common side effect is loose stools, and serious effects are rare.

Who should be careful
Some people need to check with a doctor before taking Udiliv 300, or need extra care while taking it.
When the label says not to use it
- Pregnancy or breastfeeding
- Calcified gallstones, blocked bile duct or an inflamed gallbladder

Medicines and things that interact with Udiliv 300
Some medicines change how much ursodeoxycholic acid is absorbed, and it can change other medicines. Tell your doctor or pharmacist about everything you take.
- Colestyramine, colestipol, charcoal and antacids with aluminium: they bind it, so keep a gap of at least 2 hours
- Ciclosporin: its blood level may need checking
- Ciprofloxacin: absorption may fall
- Oral contraceptives: they can work against gallstone dissolution
If someone takes too much
The main effect of taking too much is diarrhoea. If someone has taken a lot more than prescribed, call 112 or go to the nearest hospital and take the medicine pack with you.
Storage

Regulatory status in India
