It's important to work with your gyne on your choice of birth control pills. There are many on the market, and they have some important considerations. Sometimes small differences can make for increased tolerance of the side effects. For instance birth control pills have both estrogen and progesterone in them. But the progesterone are actually derivatives of testosterone and not a true progesterone. Because of the type of compound the progesterone in birth control it can be metabolized to other hormones, and in the case of some of the progesterone compounds in the pill it can be metabolized to extra estrogen in your system. This is true of pills with norethindrone and norethindrone acitate and ethynodiol diacetate as well as those that contain norethynodrel. It has been controversial as to how much estrogen the different compounds produce but we think it's about a 2/1 ratio. So if your pill is supposed to have 20 mcg of estrogen, but it also has 1 mg of noretheindrone acetate which gets metablized to 2 mcg of an estrogen, making the estrogen about 10% higher in reality. if you are on a 10 mcg estrogen pill then the extra 2 mg makes your estrogen dose about 20% higher. On the other hand this bit of a difference can be better cycle control for some women, so it's not always a negative, it can be a positive. So if you are having what your physician thinks are estrogenic side effects, don't just look to the specific estrogen in your pill, you also have to consider the progesterone in your pill!
