Happy Birthday to "the pill"

[canoestripper]

It was on this day in 1960 that the U.S. Food and Drug Administration approved the use of the world's first birth control pill.

It was one of the first times a drug had ever been approved by the FDA for a purpose other than to cure an illness or relieve pain. It was also the first time that a new medication was known not by its official name, Enovid-10, but simply as "the pill."

Some people hoped it would end unwanted pregnancies but today about 50 percent of all pregnancies in the U.S. are unplanned.

Interestingly enough my doctors keep telling me that a number of "pill" users are prescribed the drug for reasons other than birth control. I am one of these people, and I know of others on this board that have mentioned they are too.
I tried to research this number, but I couldn't come up with anything concrete. Does anyone know what percentage of "pill" users take the pill for medical reasons? It's an interesting fact to know, I think.
