Gave 9 mo. 3 tsp childrens tylenol (acetaminophen). he is 22 lbs. used wrong measure. so worried. will this harm his liver?

Tylenol (acetaminophen) and babies: One time over dose of this type should have no long lasting effects on your child. I appreciate that you are paying attention. Too much tylenol (acetaminophen) or Acetaminophen is dangerous for all humans. But, you are a good mom and this is not to be worried about.

Not likely: Single dose error that was not massive unlikely to cause significant damage--but would call poison control # to be sure. They are the experts, and there for just such questions.

Possibly: The chances of toxicity increase for total amount given, dehydration, viral illness. The amount given for the listed weight is not at a level likely to cause liver damage, but may be a problem if other variables are in play.This assumes that you gave the child the 160mg/5cc liquid and not the 100mg/ml drops. If it was the drops you need to go to the er.

Very unlikely: The amount of tylenol (acetaminophen) infant ingested is very unlikely to cause liver damage.
