Looking for pain relief but wondering about the difference between one pain reliever and another?
To help you sort through the options, WebMD consulted four medical experts. Read on to learn what they say about the differences between over-the-counter (OTC) pain relievers and how to use them safely. Then use the charts to compare pain relievers and see their brand names.
OTC Pain Relievers Are Not All the Same
Acetaminophen and nonsteroidal anti-inflammatory drugs (NSAIDs) are the two main types of OTC pain relief products.
However, not all pain relievers do this in the same way. Different pain relievers affect the body differently -- and have different side effects.
Although these products are effective at relieving pain, not everyone responds to them the same way. “So if one type of pain reliever doesn’t work for you, another might,” says Bimal Ashar, MD, associate professor of medicine at the Johns Hopkins University School of Medicine.
How Accidental Overdoses Can Happen
NSAIDs and acetaminophen can cause problems when not used according to the recommendations on the label. “Nonprescription does not mean nontoxic,” says Edward Krenzelok, PharmD, director of the Pittsburgh Poison Center and Drug Information Center at the University of Pittsburgh Medical Center. “If you take a higher dose than recommended or take it for longer than advised, there can be serious adverse effects.”
Taking too much acetaminophen (overdose), for example, can cause liver damage.
“People don’t realize that acetaminophen is in hundreds of pain relief products. It’s found in cough and cold remedies, pain relievers, and prescription medications,” says Miranda Wilhelm, PharmD, clinical assistant professor at the Southern Illinois University Edwardsville School of Pharmacy. “So consumers often don’t recognize that they are taking two different products with the same ingredient.”
To compound the problem, many manufacturers have listed acetaminophen on labels as “APAP” (the abbreviation for another name for acetaminophen, “N -acetyl-p-aminophenol”). The FDA has mandated new labeling that clarifies this. “But many people still have products in their home with older labels, so it’s important to check,” Wilhelm says.
