I'm in the US, I see drug commercials all the time, but I don't understand how they work.

Am I just supposed to go to my GP and ask for a drug I saw on TV? Are there really that many drugs so that any decent GP doesn't know most of them?

I think that's exactly how its meant to work. I'm sitting at home, and I have a bad stomach, an advert comes on the TV: "Do you have a bad stomach? Ask your GP about engorgolate today!". So I do. 2% of GPs then end up prescribing it

Ah that makes sense, thanks for writing this out
