The Food and Drug Administration is strengthening warnings on some common painkillers saying they cause increased risk of heart attack and stroke. The FDA conducted a review on new safety information and now want the drug makers to change the warning labels on certain NSAIDs. NSAIDs, or nonsteroidal anti-inflammatory drugs, are over-the-counter or prescription medications such as Advil, Ibuprofen, Aleve, Naprosyn, or Celebrex.
