Food and Drug Administration (FDA) regulations require that if prescription drug manufacturers make representations in advertisements about what their products can cure, then they must also make disclosure about the potential side effects of the drug. This is one way that the regualtory system works to protect the consumer. Commercials, such as the examples below, make a viewer understandably cautious about their prescription drug intake.
The Celebrex commercial below is an example of the other kind of ad - one that makes no positive claims and therefore need not disclose potential side effects.
Unfortunately, I was not able to find a video of the more recent Celebrex ads to exhibit the category of "language butcherng ads." The new ads warn that "patients taking aspirin and the elderly are at increased risk of stomach bleeding and ulcers." Where are those patients taking the elderly?
