simmer down.....
This is straight from the website --
ORTHO TRI-CYCLEN® LO is a "triphasic" birth control pill just like ORTHO TRI-CYCLEN®. While both ORTHO TRI-CYCLEN® LO and ORTHO TRI-CYCLEN® deliver low levels of progestin over the course of your cycle, ORTHO TRI-CYCLEN® LO delivers a lower amount of estrogen—25 mcg compared to 35 mcg.
I realize that's not the whole answer to your question. Back in the day I took the regular Ortho Tri Cyclen and it made me crazy. I'm not a fan of bcp, instead I use the ring and enjoy the even level of hormones.
Honestly, I wouldn't take generic birth control ANYTHING. I don't want to become a statistic in the package insert. I'm in pharmaceutical sales, and I do use generic medications, but three I would never use (if I had to take all of them) would be birth control, any cardiovascular medication and thyroid meds. But that's just my two cents.
