My 18 year old daughter just took tylenol pm that has 650mg acetaminophen in it and 800 mg ibuprofen...should i be worried?

No...: Ibuprofen (advil/motrin) and Acetaminophen (tylenol) are different in chemical structure, thus for this occasion you are safe from serious side effects. Ibuprofen reduces inflammation in addition to pain/fever. Acetaminophen lowers fever and reduces aches and pains, but not "inflammation." tell your daughter to stick to one or the other based on her symptom improvements. This simplifies things!

No: In general up to 4000 mg of Acetaminophen in a single day (not day after day) is thought to be safe.
