Last I remember from the US medication commercials, there were about 5 seconds at the very end of the commercial when the narrator would actually read off the side effects really quickly in a monotone voice so that you couldn't understand them anyway. :-}

For example, "Side effects are rare but may include nausea, headaches, diarrhea, and vomiting."

Hmm, then there came something about talking to your doctor if your symptoms worsen or blah blah blah, but it's been too long and I don't remember exactly how it went.

Isn't that written in the package insert of the medicine? In Germany, Austria... they do mostly always say this slogan at the end of medicine commercials.

in UK.

I don't know about adverts because I rarely watch TV when I'm in the UK.

Package inserts/PILs, however ...
