I just talked to my CF nurse about the use of that drug today. I have an almost four year old who is a terrible eater (although gains weight pretty well with high cal milk) and vomits a lot. We are always surprised when he vomits that the food is from hours and hours before so we think that there is a motility issue. We're going to do an x-ray tomorrow as a first course of action and then possibly try the drug. I'd also love to hear any input.
