Choosing the Right OTC Pain Reliever
Acetaminophen, ibuprofen, or naproxen? A practical guide to picking the right over-the-counter pain reliever for your situation — and using it safely.
Acetaminophen (Tylenol)
Works centrally rather than reducing inflammation. A good first choice for headaches, general aches, and fever, and it's gentler on the stomach than NSAIDs. The main risk is liver toxicity at high doses — it hides in many combination cold and flu products, so it's easy to accidentally double up. Keep your total daily dose under the label maximum across everything you take.
Ibuprofen (Advil, Motrin)
An NSAID that reduces inflammation as well as pain — a better fit for muscle strains, joint pain, menstrual cramps, and inflammatory headaches. Take it with food to protect your stomach, and use caution if you have kidney disease, stomach ulcers, or are on blood thinners.
Naproxen (Aleve)
Also an NSAID, with a longer duration of action — useful when you don't want to redose every four to six hours. Same stomach and kidney cautions as ibuprofen apply.
A Quick Comparison
Acetaminophen — reduces fever without the stomach irritation of NSAIDs.
Ibuprofen or naproxen — both reduce swelling as well as pain.
Acetaminophen — but watch total daily dose across all products.
Naproxen — fewer doses needed through the day.
