Ursodiol is used to dissolve gallstones in people who do not want surgery or cannot have surgery to remove gallstones. Ursodiol is also used to prevent the formation of gallstones in overweight people who are losing weight very quickly. Ursodiol is used to treat people with primary biliary cirrhosis (PBC; an autoimmune liver disease). Ursodiol is in a class of medications called gallstone dissolution agentss. It works by decreasing the production of cholesterol and by dissolving the cholesterol in bile to prevent stone formation and by decreasing toxic levels of bile acids that accumulate in primary biliary cirrhosis.
HOW should this medicine be used?
Ursodiol comes as a capsule and as a tablet to take by mouth. It is usually taken two or three times a day with or without food to treat gallstones and two times a day to prevent gallstones in people who are losing weight quickly. If you are taking the tablets to treat primary biliary cirrhosis, they are usually taken 2 or 4 times a day with food. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take ursodiol exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
If you need to break the tablet for your specific dose, place the tablet on a flat surface with the scored section on the top. Hold the tablet with your thumbs close to the scored part and apply gentle pressure to snap the tablet into two parts. Take the half tablet as directed by your doctor with food, and store the other tablet half in the opened blister package. Use the stored half tablet within 7 days. If you have any questions, your doctor or pharmacist will tell you how to break the tablets and how you should take them.
This medication must be taken for months to have an effect. If you are taking ursodiol capsules to dissolve gall stones, you may need to take ursodiol for up to 2 years. Your gallstones may not completely dissolve, and even if your gallstones do dissolve you may have gallstones again within 5 years after successful treatment with ursodiol. Continue to take ursodiol even if you feel well. Do not stop taking ursodiol without talking to your doctor.
