If I need a doctor's perscription to get it anyway, it should be advertised to doctors only, not the general public. Awareness of the options available is their responsibility. Receiving a trained expert's diagnosis and their recommended treatment is the entire point of why I'm seeing a doctor in the first place.

If it's not a restricted pharma product, fine, I guess. I don't like ads for those either, but I can't come up with a compelling argument why a product I can get at the grocery store can't be publicly advertised, beyond my gut feeling that it's a mildly scummy practice.
