Studies in animals have shown no bad effects to the unborn but sometimes things happen in humans that doesnt happen in animal studies and there are no studies that thave been done on pregnant women. Promathazin given in the last two weeks of pregnancy can cause platelet problems and bleeding in the newborn. Promethazine should only be taken by a pregnant woman if the benefits outweigh the risk to the baby so it depends on why you need to take it. Have you discussed it with your OB Dr?
