Common pain relievers like ibuprofen and naproxen — called nonsteroidal anti-inflammatory drugs,or Nsaids — are the go-to drugs for headaches and pulled muscles,arthritis and menstrual cramps. Their labels have long warned that overuse may increase the risk of heart attack and stroke,but we rely on them as we do on few other medications. And for good reason: They work.

Occasional use of Nsaids is not likely to lead to cardiovascular consequences. But an authoritative and ambitious new analysis that included data from over 600 trials,including detailed case histories of more than 350,000 patients,concludes that people who take high doses of Nsaids daily increase their cardiovascular risk by as much as a third,compared with those taking a placebo. The one exception is naproxen,which may actually have a protective effect against heart attacks.

The absolute risk of cardiovascular trouble for those who take high doses of other Nsaids regularly is still quite small. Nonetheless,the findings suggest that people who rely on them may want to explore alternative pain management methods,especially if they have other risks for heart disease,or a family history of it.

“There aren’t really good choices for chronic pain,” said Dr Marie R Griffin,a preventive medicine specialist at Vanderbilt University Medical Center who wrote a commentary on the new study,published last month in The Lancet. In addition to the potential harm,Dr Griffin said,painkillers like Nsaids often don’t really do the job when it comes to chronic pain.

Nsaids include ibuprofen,sold under the brand names Motrin and Advil; naproxen,sold as Aleve,Naprosyn,Anaprox and Naprelan; and celecoxib,sold as Celebrex and available only

by prescription.

Aspirin,also an Nsaid,is primarily used in low doses to prevent heart disease and was not included in the analysis. Evidence has been gathering that nearly all Nsaids pose some cardiovascular risks in heavy users,said Dr Garret A FitzGerald,the director of the Institute for Translational Medicine and Therapeutics at the University of Pennsylvania and one of the new report’s authors.

Diclofenac,which is not used much in the United States,and COX-2 inhibitors like celecoxib,marketed as Celebrex,account for three heart attacks and strokes a year on average — one of them fatal — among every 1,000 patients taking high doses regularly,the study found. Officials at Pfizer,which makes Celebrex,say it is not approved for use at doses higher than 400 milligrams a day,and they have maintained for years that it does not carry the same risks as other COX-2 inhibitors,an assertion that Dr FitzGerald said “is not borne out by the data.”

Ibuprofen taken at high daily doses of 2,400 milligrams also significantly raised heart attack risk,possibly doubling it. But data about ibuprofen is scant,making it difficult to precisely assess the risk.

Naproxen,even at high daily doses of 1,000 milligrams,does not increase cardiovascular risk and may actually have a protective effect similar to that of aspirin,the analysis found. Unfortunately,it also appears to cause more gastrointestinal problems than other Nsaids.

All Nsaids increase the risk of heart failure,the study found. Nsaids may also cause damage to the liver and kidneys and raise the risk of high blood pressure.

Dr Brian Walitt,a rheumatologist and associate professor at Georgetown University,said: “But these are population-wide risks. There are people with arthritis using these drugs every day,or most days,and most of them never have a problem.”

Choosing the right painkillers

*For people who can’t function without daily use of Nsaids,“our advice has always been,use the lowest dose you can for the least amount of time you can,” Dr Steven Nissen,chairman of cardiovascular medicine at the Cleveland Clinic,said.

*If you have heart disease or risk factors for it,your doctor should assess the risk of chronic Nsaid use based on your personal medical and family medical history. A history of gastrointestinal problems should be part of the equation as well.

*Naproxen is a good first choice for chronic pain,as long as your stomach can

tolerate it.

*If you are on a low-dose aspirin regimen to prevent heart disease,avoid Nsaids containing ibuprofen,which may weaken the beneficial effect of aspirin.
