GoodRx [2] provides information about the safety of taking Tylenol (acetaminophen) with Advil or Motrin (ibuprofen). While it is generally safe to take these medications together, it is important to follow the recommended dosages and not exceed the maximum daily dose of either medication. It is also important to talk to a healthcare provider before taking these medications together if you have any underlying medical conditions or are taking other medications.
