While you might think Yaz and Yasmin are the same just because both come from the same company, there are, however, certain differences between the two. Although both are birth control pills used to prevent pregnancy, their compositions are not totally the same. The quantity of estradiol, a hormone that is produced in the ovaries, is higher in Yasmin compared to the quantity contained in Yaz.
Unlike Yaz that contains 20mcg Ethinyl estradiol, Yasmin contains 30mcg Ethinyl estradiol. As part of the instructions that come with the two medications, Yaz is expected to be taken for three weeks and three days, whereas Yasmin is expected to be taken for just three weeks. However, after this period, placebo pills or inactive pills are to be taken to reduce the side effects of the two medications. Unlike Yasmin, that is used mainly to prevent pregnancy, Yas can also be used to reduce premenstrual symptoms.
