I see the commercial a lot when I am on the treadmill in the afternoon, which is telling of who the drug company is targeting during this time. They talk about the risk and how they are increased for certain women, by certain activities. They talk about how they don't prevent std's and how they are meant for women in committed relationships. The doctor that suggested/prescribed this as the method of choice doesn't appear to have followed the criteria from the commercial.
The problem here appears to be the doctor. These people don't seem to understand that they don't have to do what the doctor wants. They have a choice.
