What's wrong with arthritis drug Vioxx?

WHY VIOXX IS BEING PULLED: The popular arthritis drug doubled the risk of heart attack and stroke compared to people taking a dummy pill, according to a study.

WHAT IT MEANS: People should stop taking it and ask their doctors for alternatives.

FALLOUT: Could boost sales of other similar prescription drugs and over-the-counter pain relievers.

BIG PICTURE: A blow to high hopes that Vioxx, in addition to fighting arthritis pain, might help prevent certain cancers.
