Duration of Udiliv 300 (Ursodeoxycholic Acid) Treatment
For primary biliary cirrhosis (PBC), Udiliv 300 should be taken long-term indefinitely, as prolonged administration is associated with survival benefit and delayed need for liver transplantation. 1, 2
Treatment Duration by Indication
Primary Biliary Cirrhosis (PBC)
- Long-term continuous therapy is required at 13-15 mg/kg/day (typically 900 mg/day for a 67 kg patient, or three 300 mg capsules daily) 1, 3
- Treatment should continue indefinitely as this is a chronic disease requiring ongoing management 4, 2
- Long-term UDCA treatment delays histological progression when started at early disease stages 1
- Discontinuation is not recommended unless adverse effects occur or the patient undergoes liver transplantation 1
Gallstone Dissolution
- Treatment duration is 6-38 months depending on response 5, 6
- Monitor with ultrasound at 6-month intervals during the first year 5
- If partial stone dissolution is not seen by 12 months, the likelihood of success is greatly reduced and discontinuation should be considered 5
- Once complete dissolution is confirmed on repeat ultrasound (within 1-3 months of apparent dissolution), therapy should be continued briefly to ensure stability 5
- Most patients achieving complete dissolution show partial or complete dissolution at the first on-treatment reevaluation 5
Gallstone Prevention During Rapid Weight Loss
- Treatment duration matches the period of rapid weight loss 5
- Recommended dose is 600 mg/day (two 300 mg capsules daily) 5
- Continue throughout the weight loss period and potentially for a short period afterward 5
Monitoring Schedule
For PBC Patients
- Regular monitoring of liver biochemistry is essential to assess treatment response 1
- Biochemical response should be evaluated after 1 year of therapy to identify patients at risk of progressive disease 1
- Annual reassessment of biochemical markers of cholestasis is recommended 1
For Gallstone Dissolution
- Ultrasound imaging at 6-month intervals for the first year 5
- If dissolution appears complete, confirm with repeat ultrasound within 1-3 months 5
- Laboratory monitoring including liver function tests should be performed regularly, as UDCA does not adversely affect these parameters 6
Important Considerations
When to Continue Treatment
- PBC patients should remain on therapy indefinitely unless contraindications develop 1, 2
- Gallstone patients showing partial dissolution at 6 months should continue therapy as they are likely to achieve complete dissolution 5, 6
- Most biliary symptoms disappear within 3 months of starting therapy 6
When to Discontinue Treatment
- Gallstone patients showing no partial dissolution by 12 months have greatly reduced likelihood of success 5
- If hepatic decompensation occurs (particularly in advanced disease), discontinuation may be necessary 7
- Development of severe adverse effects warrants discontinuation 8
Critical Safety Warning
- Do not use doses exceeding 15 mg/kg/day for PBC, as very high doses (28-30 mg/kg/day) have shown harm with increased mortality and need for liver transplantation 4, 8
- UDCA is not recommended for routine use in primary sclerosing cholangitis due to limited efficacy and potential harm at high doses 1, 4
