Side effects?

Charles Krauthammer:

...

Consider the oddity of those drug commercials on television. Fifteen seconds of the purported therapeutic effort, followed by about 45 seconds of a rapidly muttered list of horrific possible side effects. When the ad is over, I can't remember a thing about what the pill is supposed to do, except perhaps cause nausea, liver damage, projectile vomiting, a nasty rash, a four-hour erection and sudden death.

Sudden death is my favorite because there is something comical about it being a side effect. What exactly is the main effect in that case? Relief from abdominal bloating?

...

There is a stop smoking drug ad, that by the time they finish with the side effects including suicide you wonder why someone might not opt for a much slower death from smoking. As for the four hour erection, I don't think I have ever heard a man or a woman complain about such an effect. I have heard some say to bring it on after hearing the ad.
