Naproxen
naproxen · Say it: NAP-rox-en
Naproxen is a prescription NSAID tablet used to relieve pain and the signs of conditions such as arthritis, gout, tendonitis, bursitis, and painful menstrual cramps. It carries serious warnings about heart attack, stroke, and stomach bleeding.
⬛ Boxed warning (the FDA's strongest warning)
The boxed warning says NSAIDs can cause an increased risk of serious heart problems, including heart attack and stroke, which can be fatal. This risk may happen early in treatment and may increase with longer use. Naproxen is not to be used right before or after coronary artery bypass graft (CABG) heart surgery. NSAIDs also cause an increased risk of serious stomach and intestine problems, including bleeding, ulcers, and holes (perforation) in the stomach or intestines. These can be fatal, can happen at any time, and may occur without warning symptoms. Older adults and people with a past history of stomach ulcers or stomach bleeding are at greater risk.

The dose may be changed based on how the patient responds. Naproxen sodium is described as useful for acute painful conditions when fast pain relief is wanted. The label says naproxen products should not be used together, because they all circulate in the body as the same active form. Follow the instructions from your prescriber or pharmacist.
