The idea of advertising prescription drugs is absolutely bonkers in and of itself. If I recall correctly, the only reason they say "Ask your doctor about..." was a regulatory compromise that allowed such advertising. Telling the general public to simply "take Procrapin for their constipation" was deemed too extreme: The general public doesn't have the medical training to diagnose themselves or recommend treatment, but instead the manufacturer was allowed to urge the general public to nag their doctor about a medicine--that was seen as fine.
