From the Guidelines

Administration of Lactulose During Induction of Labor

Lactulose can be given to a patient undergoing induction of labor, as it is considered safe for use during pregnancy 1.

  • Safety in Pregnancy: The use of lactulose, an osmotic laxative, is supported by evidence as a treatment option for constipation in pregnant individuals, which may occur due to hormonal, medication-related, and physiological changes 1.
  • Constipation Management: Constipation is a common issue during pregnancy, affecting 20%–40% of pregnant persons, and lactulose is among the recommended treatments, including dietary fiber and polyethylene glycol–based laxatives 1.
  • Potential Side Effects: While lactulose can cause maternal bloating, it is generally considered safe for administration during pregnancy, unlike stimulant laxatives, which should be avoided due to conflicting safety data 1.
  • Clinical Considerations: In the context of labor induction, the primary concern would be ensuring the patient's hydration status and electrolyte balance are maintained, as excessive use of osmotic laxatives like lactulose could potentially cause dehydration 1.
  • Alternative Considerations: However, given that lactulose is deemed safe for use in pregnancy, its administration during induction of labor would not be inherently contraindicated, provided that the patient's overall condition and potential for dehydration are closely monitored.

From the Research

Lactulose Administration During Induction of Labor

  • There are no research papers to assist in answering this question, as none of the provided studies mention the use of lactulose during induction of labor 2, 3, 4, 5, 6.
  • The studies focus on various methods and medications used for labor induction, such as prostaglandins and oxytocin, but do not discuss the administration of lactulose in this context.
  • The safety and efficacy of medications like dinoprostone gel and vaginal insert for induction of labor are discussed in some studies 4, but lactulose is not mentioned as a medication used for this purpose.
