The acting commissioner of the Food and Drug Administration says "all regulatory options" are open but it's too early to say what action might be taken on Celebrex and Aleve.
Studies have linked the arthritis pain killers with an increased risk of heart attack, but both are staying on the market.
For now, Doctor Lester Crawford says people taking Aleve, an over-the-counter drug, should strictly follow the directions on the label. People who use Celebrex should consult with their doctor about whether there's something else they might be able to take in its place.
A whistleblowing FDA scientist, Doctor David Graham, appearing on NBC, says the agency didn't do appropriate studies to establish that the drugs were safe. He says the agency's focus has increasingly shifted away from protecting the public.
But Crawford says FDA is "not in the pocket" of drug companies.
