Acetaminophen vs. Ibuprofen: When to Use Which

Two everyday painkillers that aren't interchangeable.

Most medicine cabinets have both, and most people grab whichever's closest. They actually shine in different situations.

How they differ

Ibuprofen (Advil, Motrin) is an anti-inflammatory — better for swelling, sprains, muscle aches, and menstrual cramps. Acetaminophen (Tylenol) isn't anti-inflammatory but is a solid pain and fever reducer, and it's gentler on the stomach. Their risks differ too: ibuprofen can bother the stomach and kidneys, while too much acetaminophen can harm the liver.

The dosing trap

The big acetaminophen risk is accidental overdose, because it's hidden in many combo cold and flu products. Stacking a Tylenol on top of a cold medicine that already contains it is an easy, dangerous mistake.

The move

Reach for ibuprofen when inflammation is involved, acetaminophen for general pain or fever or a sensitive stomach. Always check combo medicines for hidden acetaminophen, stick to the labeled dose, and ask a pharmacist if you're unsure — they're an underused resource.
