Some commonly-used painkillers may increase the risk of stroke, according to the findings of a new study.

According to Reuters, researchers in Taiwan studied nearly 38,000 adults over the age of 20 who had suffered a stroke in 2006, then looked at their use of NSAID painkillers in the month before the stroke and compared it to use in the prior three to six months.

NSAID mediations include over-the-counter drugs such as aspirin, ibuprofen (Advil, Motrin and other brands) and naproxen (Aleve).

They found that the use of any NSAID in the 30 days before the stroke was linked to an increased risk – of anywhere from 20 percent to 90 percent, depending on the medication.

A spokesman for the American Heart Association (AHA) told the news provider that the results confirm the agency’s current recommendation that individuals should use NSAIDs at the lowest dose and for the shortest time necessary to relieve their pain and to limit cardiovascular risks.

NSAIDs had previously been linked to an increased incidence of heart attacks.

The AHA recommends people try easing pain with acetaminophen (Tylenol) before using NSAIDs. Aspirin is also an option, although it is an NSAID. Experts say previous research has shown it is protective against heart attacks.
