Using castor oil and a balloon catheter to induce labor in multiparous women
Official title: The Effect of Combining Balloon Catheter With Castor Oil Ingestion for Cervical Ripening on Time to Delivery Among Multiparous Women.
Run by Holy Family Hospital, Nazareth, Israel · NCT06335017 · Data updated 2026-11-12
This study is testing if taking castor oil with orange juice along with a balloon catheter can help women who have given birth before have their babies faster and easier.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates for this study are multiparous women over 18 years old with a term pregnancy and a Bishop score of 6 or less.
✕Probably not a fit
Patients who have had a previous cesarean delivery or have contraindications to vaginal delivery may not benefit from this study.

What this trial studies
This clinical trial investigates the effectiveness of combining castor oil ingestion with an extra-amniotic single balloon catheter for cervical ripening in multiparous women. Participants will be randomly assigned to either a study group, which will consume a mixture of castor oil and orange juice followed by catheter insertion, or a control group that will only receive the catheter without castor oil. The study aims to determine if this combination reduces the time from induction to delivery and evaluates any potential side effects for the mothers. The trial will include women who meet specific eligibility criteria, ensuring a focused examination of the intervention's efficacy.
Why it matters
Potential benefit: If successful, this approach could lead to shorter labor times and improved outcomes for mothers and babies during childbirth.
How similar studies have gone: Previous studies have shown mixed results with similar approaches, indicating that while some combinations have reduced labor duration, this specific combination of castor oil and balloon catheter is relatively novel.
