Join Our Motegrity® (PRUCALOPRIDE) & Breastfeeding Study

Mommy’s Milk is looking for people who are nursing and who are currently taking Motegrity® (prucalopride) for the treatment of functional constipation. Our research study will examine whether Motegrity® can be found in human milk and whether this has any effect on the infant’s growth or development.

Participation includes providing 4-7 human milk samples over a 24-hour period before and after taking a dose of Motegrity®, phone interviews about the nursing parent and their baby’s health and environment, questionnaires about baby’s growth and development, and releasing baby’s medical records.
