How soon can you take tylenol (acetaminophen) after you take ibuprofen?

The two don't compet. Tylenol (acetaminophen) is absorbed from the gut and distributed through the body in a similar fashion to ibuprofen. They can be taken at the same time but i seldom advise so. Tylenol (acetaminophen) is broken down by the liver & removed in the bile. Ibuprofen is broken down & eliminated through the kidneys .The Ibuprofen is a 6-8 hour med while tylenol (acetaminophen) is a 4hr. Both every 8h sounds better than alternating every 4 if u must.
