Yaz Vs. Yasmin

Many people are unaware of the difference between Yaz versus Yasmin. While the two birth control pills are very similar in many ways, there are some minor differences.
Yaz® (drospirenone/ethinyl estradiol) and Yasmin® (drospirenone/ethinyl estradiol) are both combined oral contraceptives that contain both an estrogen and a progestin. They work to prevent pregnancy by stopping ovulation (the maturation and release of eggs from the ovaries) and altering the cervical mucus and the lining of the uterus.
Yasmin and Yaz are both different from traditional birth control pills in an important way. The progesterone that they use (drospirenone) is closely related to spironolactone, a medication used as a diuretic ("water pill"). Drospirenone has anti-androgenic activity, which means that it works against testosterone and other "male" hormones. All women have a small amount of these hormones, which can cause acne and other problems.
The primary difference between Yaz and Yasmin is that Yaz contains 24 active pills and 4 inactive pills, which have no active ingredients. Most birth control pills (including Yasmin) have 21 active pills and 7 inactive pills. Having fewer inactive pills seems to decrease some of the bothersome symptoms that occur just before and during your period.
