As reported in the media, The Children’s Hospital of Philadelphia’s (CHOP’s) Division of Gastroenterology is conducting an FDA-funded study to determine if components of PEG 3350 are absorbed into children’s blood. PEG 3350 is contained in certain over-the-counter medications commonly prescribed by physicians to treat children with constipation. The FDA has received reports from parents who are concerned that this medicine has caused neurobehavioral symptoms in their children.
