Yasmin birth control pills were the first to use a new form of progestin, drospirenone. Together with ethinyl estradiol (EE), the drospirenone in Yasmin birth control pills creates a hormonal state for the user in which her normal monthly egg release (ovulation) doesn’t occur — thus preventing pregnancy.

Yasmin vs. YAZ Birth Control

There has been a significant level of confusion regarding “Yasmin” birth control and “YAZ” birth control, another oral contraceptive provided by the same pharmaceutical company, Bayer HealthCare. They are not the same birth control method. Here are some major differences:

  • Yasmin birth control was introduced to the U.S. market first (in 2001; YAZ was introduced in 2006).
  • YAZ birth control pills have a lower level of EE: 20 micrograms per pill versus 39 micrograms per Yasmin pill.
  • Yasmin’s daily active pills are taken for 21 days, followed by 7 days of placebo (“dummy”) pills, whereas YAZ active pills are taken for 24 days, followed by 4 placebo pills.

Yasmin Side Effects

There was some thought that Yasmin would not cause the weight gain experienced by some women using oral contraceptives because drospirenone can decrease excess levels of sodium (salt) and water in the body (i.e., “water weight” or bloating). However, drospirenone can also increase the body’s potassium levels, and thus its use is discouraged in women who have liver or kidney problems, which could result in dangerously high potassium levels.

As is true for all hormone-based contraceptives, the use of Yasmin or YAZ birth control pills increases the possibility of blood clot, stroke, deep vein thrombosis, and heart attack. A recent study in the British Medical Journal, however, found that oral contraceptives such as Yaz, which use drospirenone, have a higher likelihood than other oral contraceptives to cause dangerous thrombotic events. Any woman who is considering Yasmin or YAZ should first discuss her medical history and lifestyle with a knowledgeable healthcare provider and also discuss the availale oral contraceptives with this additional information.
