NSAIDs for Pain: What They Are, How They Work, and Which Ones Actually Help

When you’ve got a headache, a sore back, or swollen knees, NSAIDs for pain, a class of drugs that reduce inflammation and block pain signals. Also known as nonsteroidal anti-inflammatory drugs, they’re the go-to for millions who need quick, reliable relief without a prescription. Unlike acetaminophen, which just dulls pain, NSAIDs tackle the root cause—swelling and irritation—making them especially useful for arthritis, sports injuries, or menstrual cramps.

Not all NSAIDs are the same. Ibuprofen, a fast-acting NSAID found in brands like Advil and Nurofen kicks in within 30 minutes and lasts about 4 to 6 hours. Naproxen, the longer-lasting option sold as Aleve, takes a bit longer to start working but can keep pain under control for up to 12 hours. Then there’s aspirin, less common today for pain but still used for heart health. Each has different risks: ibuprofen can upset your stomach more easily, while naproxen might raise blood pressure in some people. You don’t need to guess which one to pick—knowing how your body reacts matters more than brand names.

People often turn to NSAIDs because they work fast and are cheap. But they’re not harmless. Long-term use can damage your stomach lining, hurt your kidneys, or interfere with blood pressure meds. That’s why many users look for alternatives—like topical gels, physical therapy, or even herbal options—which show up in our collection.
