Yes. I didn't know that until right this second.

Yep, same here. I've always just used whichever OTC pain killer was most convenient and have never noticed a difference between them. They all seem mildly effective at reducing discomfort. I have taken Ibuprofen for headaches many times and it seems just as helpful as anything else.

Wild.

Yes those of us that know ibuprofen is better for headache than acetaminophen.

Actually taking both together is more effective. Take one tablet of ibuprofen and one of acetaminophen.
