Treatment will be given for as long as the child needs any TPN AND has a conjugated bilirubin greater than 2 mg/dL for a maximum of 5 months. If the infant no longer is requiring any TPN, then the Omegaven will be stopped regardless of bilirubin. If the bilirubin is less than 2 mg/dL but the child still requires TPN, then the Omegaven will be continued up to a total of 5 months or whenever the infant no longer requires TPN. The reason for stopping Omegaven when the infant no longer requires TPN is that this would be the only reason many infants would still need IV access and therefore the risk of maintaining IV access only for the medication is likely to exceed the benefit of Omegaven at that point.
