There was just a thread on this a few days ago. Try doing a search. I just asked my OB/GYN about it and she told me that it's much more expensive than regular pills. So, she wrote me a prescription for regular pills that would work the same exact way. She instructed tha pharmacy to give me 4 packs of pills that will last 12 weeks since I won't be taking the placebo. Normally, 4 packs would last 16 weeks. But, then I get an extra refill at the end to compensate for the "lost"pills. It's the same concept as Seasonale, just cheaper. Seasonale, isn't any different than other pills. It's just the way it's marketed and filled that makes it "special".
