Interventions



 





Assess patient carefully for suitability of ursodiol therapy. Alternative therapy should be reviewed before using ursodiol. Give drug in two to three divided doses. Do not administer drug with aluminum-based antacids. If such drugs are needed, administer 2–3 hr after ursodiol. Schedule patients for periodic oral cholecystograms or ultrasonograms to evaluate drug effectiveness at 6-mo intervals until resolution, then every 3 mo t o monitor stone formation. Stones recur within 5 yr in more than 50% of patients. If gallstones appear to have dissolved, continue treatment for 3 mo and perform follow-up ultrasound. Monitor LFTs periodically. Carefully assess patient if any change in liver function occurs.

Teaching points







Take drug two to four times a day. Take the drug as long as prescribed. It may be needed for a long time. This drug may dissolve your gallstones; it do es not “cure” the problem that caused the stones, and in many cases, the stones can recur. Medical follow-up care is important. Arrange to receive periodic X-rays or ultrasound tests of your gallbladder; you also will need periodic blood tests to evaluate your response to this drug. Keep foll ow-up appointments.



Do not take with any aluminum-based antacids.
