New research confirms there are significant risks linked to the pain killer Vioxx.
A group of researchers studied follow-up data one year after patients stopped taking the drug. They found the risk for heart attack and stroke among Vioxx users remained twice that seen in participants who didn't use the drug. Experts say the effects seem to apply to all the drugs in this class, however more research is needed.
Vioxx was taken off the market in 2004.
