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.
