Urso is primarily used to treat primary biliary cholangitis (PBC) and to dissolve cholesterol gallstones in patients who cannot undergo surgery or prefer non-surgical treatment. It may also be used for other liver and bile duct conditions as determined by a healthcare provider.
Urso contains ursodiol, a naturally occurring bile acid that works by decreasing cholesterol production in the liver, increasing bile flow, and replacing toxic bile acids. This helps dissolve cholesterol-based gallstones and protects liver cells from damage.
Urso should be taken with food for best absorption. Patients should have gallstone monitoring every 6 months during treatment. Common side effects may include diarrhea, upset stomach, and nausea. Patients with certain liver conditions, bile duct blockages, or allergies to bile acids should not use this medication. Regular liver function tests are typically required during treatment.
