My fiancee took prucalopride whist we were trying for a baby and stopped about six weeks into pregnancy. what problems could taking this drug cause?

Unknown: This drug, a serotonin (5-HT4) receptor agonist, indicated for severe constipation, has not yet been approved in the United States. It has an improved cardiac safety profile over its predecessors. Data on the safety of this drug in pregnancy are very limited. In retrospect, it should have been stopped prior to attempting pregnancy. She needs to discuss her use of this drug with her obstetrician!
