You finish a hard workout, head to the shower, and peer in the medicine cabinet to consider your options: Advil? Motrin? Aleve? Maybe you reflexively grab a bottle and down two pills in a single gulp without a second thought.
“Unfortunately, many long-distance runners are chronic users of ibuprofen. Mainly, they think it’s going to reduce pain associated with exercise,” David Nieman, Dr.PH., FACSM, director of the NCRC Human Performance Lab at Appalachian State University tells Runner’s World.
But in fact, the opposite is true. Researchers have proven the persistent use of pain medicine for runners can have negative health impacts. According to a study conducted by Nieman, the chronic use of ibuprofen in long-distance runners stimulated mild endotoxemia—bacteria leaking out of the colon into the blood stream due to ibuprofen intake—and increased inflammation.
In another study, Nieman and his colleagues found taking ibuprofen during intense exercise amplified oxidative stress—an excess of free radicals (molecules that can damage your cells and cause disease) in your body. Too much oxidative stress can overwhelm your muscle tissues and possibly lead to injuries.
“Ibuprofen—especially [in] those who are chronically using it before the race, training, and during the race—tends to disrupt the lining cells of the gastrointestinal track,” Nieman says. Researchers discovered long-distance runners who took ibuprofen a week after completing a 100-mile race didn’t experience reduced inflammation or muscle soreness. Instead, Nieman says, it made things worse. “Their kidney function was altered in a negative way,” he says.
And, more recent studies back Nieman’s findings. In How to Recognize Under-Fueling and How to Fix It, researchers found ultramarathon runners who took ibuprofen experienced acute kidney injury—a sudden decrease in kidney function—at higher levels than those who received a placebo. A study the NCRC Human Performance Lab at Appalachian State University Physiological Reports, backs this up, saying that those doing ultra-distance events should avoid taking nonsteroidal anti-inflammatory drugs (NSAIDs) to avoid risk of harming the kidneys.
You don’t have to be an ultra super-stud to want to numb a creaky knee. Bill McOarberg, M.D., founder of the Chronic Pain Management Program at Kaiser Permanente in San Diego, California, says the use of over-the-counter pain medicine trickles down from competitive athletes to recreational runners. “People assume they are safe because they are sold over the counter, but pain relievers, particularly NSAIDs, can be risky,” he says.
To cut back on the risk, maintaining a rainbow diet—eating lots of colorful fruits packed with polyphenols—can help athletes naturally reduce inflammation and aid recovery, says Nieman.
But of course, runners rely on over-the counter medicines to treat more than just running related and have a killer workout on tap. Or your. So, here’s how to safely take drugstore meds to treat your aches and woes.

(Taking NSAIDs could increase muscle soreness if taken before or too soon after exercise. Ibuprofen can allow endotoxins to slip into your blood stream, which can cause cell oxidation and result in muscle soreness.)
Acetaminophen (Tylenol)
