Bottles that were supposed to contain Children's Motrin grape chewable ibuprofen tablets might mistakenly contain an adult dose of a different kind of over-the-counter painkiller. McNiel Consumer and Specialty Pharmaceuticals says the bottles might mistakenly contain eight-hour extended release Tylenol Geltabs. The adult product contains an adult dose of acetaminophen. The children's product is a purple tablet with a grape smell. The adult product is a shiny red-and-white, gelatin-coated tablet. The suspect bottles were distributed nationwide to wholesale and retail customers between February fifth and April first. According to the American Academy of Pediatrics -- a child acetaminophen overdose can lead to nausea and vomiting, abdominal pain and liver failure.
