Just How Safe is Yaz? Women Need to Know!

The oral contraceptive Yasmin was released in 2001 by the pharmaceutical company Bayer, followed by Yaz in 2006. They differ from other birth control pills in the synthetic progesterone they utilize, drospirenone, which is marketed as less likely to cause weight gain and bloating than other birth control pills. Yaz soon became the most popular birth control pill in the U.S., due in part to a widespread advertising campaign promoting the drug as what the New York Times dubbed “a quality of life treatment,” claiming it could also clear up acne, prevent bloating and ease the depression and anxiety associated with both PMS and the controversial condition of PMDD. It prevents pregnancy at the same rate of effectiveness as all other oral contraceptives.

In 2009, the FDA requested that Bayer distribute a corrective advertisement to counter its aggressively screened commercials that were said to be making misleading assertions about the capabilities of the drug, promoting it for unapproved uses and making light of the more serious health risks (such as blood clots). However, in 2010 the drug remained the second-best-selling Bayer product, bringing in $1.5 billion in sales.

As of January 2012, there are approximately 10,000 lawsuits against Bayer by women who have suffered blood clots and by the families of those women who have died whilst taking Yaz or Yasmin. It is considered the most complained-about drug on the Internet, with thousands of women voicing concerns in online forums and support groups over health issues both physical and emotional. Jane Bennett and Alexandra Pope, authors of The Pill: Are You Sure It’s for You?, characterize many of these problems as “quality-of-life-threatening.” I have written extensively on my own experience with Yasmin in my blog, Sweetening the Pill, and for the UK Independent and have been quoted in Fabulous magazine the Washington Post

Two studies conducted with funding from Bayer revealed that Yaz and Yasmin held no higher risk of blood clots than other birth control pills. However, last month it was revealed that five other studies undertaken independent of Bayer suggested a 50-to-75 percent increased risk of clots for those taking these birth control pills in comparison to others. A former FDA commissioner, David Kessler, charged that Bayer deliberately withheld data about this early on in order to push through the drugs’ approvals. In response, the FDA called an advisory committee to evaluate the safety of birth control pills containing drospirenone. The decision had the potential to cause the drugs to be pulled off the market, but the panel voted by a four-person margin that the drugs’ benefit outweighed the risks.

Yet a government watchdog group, the Project on Government Oversight (POGO), conducted an independent investigation that revealed three of the advisors on the FDA panel had research or other financial ties to Bayer. A fourth advisor was connected to manufacturing the generic version of these pills. All four voted for Yaz and Yasmin to continue to be prescribed by doctors. POGO asked the FDA that a new advisory committee be brought together to make another assessment.

Should these developments impact women’s perspective on the birth control pill? Should we consider that use of the Pill for pregnancy prevention, let alone acne or PMS, is still today, as women’s health activist Barbara Seaman wrote in her 1969 book The Doctors’ Case Against the Pill, “like tinkering with nuclear bombs to fight off the common cold”?

Says Ms. blogger Elizabeth Kissling, professor of communication and women’s and gender studies at Eastern Washington University and past president of the Society for Menstrual Cycle Research:

I’m surprised there has not been a broader call for more research, or wider public discussions of the risks of this pill. When a drug company is withholding data and 10,000 lawsuits are pending, more than research is needed. I can’t help but wonder why we’re not seeing Congressional hearings–akin to the 1970 Nelson Pill Hearings–again, and more of an outcry from both physicians and patients.

Much of the media coverage of these recent developments and research was quick to assert the unimportance of women’s concerns. It was repeatedly reported that, when compared to the risk of blood clot development associated with pregnancy, the risk produced by taking any oral contraceptive–including Yasmin or Yaz–is of little concern. This is misleading in that it suggests there are only two states in which young women can choose to live: on birth control pills or pregnant. The fear has been voiced that any discussion of the negative impact of the Pill will prompt women to come off of it and fall unintentionally pregnant. No coverage that this writer has read discussed a comparison with non-hormonal contraceptive alternatives–which, of course, hold no increased risk of blood clots. Some of these alternatives are just as effective in preventing pregnancy as oral contraceptives, and others are more so.

According to Laura Wershler, veteran pro-choice sexual and reproductive health advocate and board director of the Canadian Federation for Sexual Health,

We need to reframe the idea that hormonal birth control is the gold standard of contraception. If women are quitting the Pill, and they have every right to do so, and they are not using alternative methods of birth control effectively, that’s proof positive that what we are teaching about contraception is incomplete and ineffective. If we make the Pill the ‘right’ choice, then why should we be upset when women stop taking it and get pregnant?

It is often claimed within news stories that the Pill “regulates” a woman’s menstrual cycle, when it, in fact, stops and replaces the cycle. All of this propaganda for the Pill is extremely misleading, and it further breeds a lack of confidence to know that Bayer paid women’s magazines to advocate for Yaz. Such actions blind women to their choices and to understanding how their bodies work. There is much research that supports the health benefits of consistent (typically monthly) ovulation, which can be found through the Centre for Menstrual Cycle and Ovulation Research.

The absence of education in body literacy is a major factor in unwanted pregnancies. However, this lack of education is beneficial to some: It helps sustain the billion-dollar profits of pharmaceutical companies.

  2. Thanks for sharing , Please do share more about unplanned pregnancy

    • Know your rights says:

      This link leads to a pregnancy crisis center whose only purpose is to prevent women from getting the abortion services they have a legal right to. Don’t be fooled. If you are pregnant and don’t want to be a mother yet, you have the legal right to access an abortion but you need to go to a center that distinctly says “planned parenthood”. Pregnancy crisis centers will lie cheat and I even have a friend that was abducted by members of her mother’s church at 19 and locked into the basement for almost a month when an abortion would cost over a $1000. She had the baby but it died hours after birth since she couldn’t access the health care she needed during the beginning of the pregnancy and she was fired from her job for not showing up for so long. These people are crazy, they don’t care if the baby is going to die or if you were raped or if a baby would hurt you health, they are only concerned with you while your pregnant and then you and your baby are garbage to them. They certainly won’t agree to raise taxes to educate your child or keep guns our of schools. It’s all about keeping choice away from women. John Oliver explains it all here:

  3. i was on yaz birth control for 4 years, im off it for a year now and still not pregnant, what could be wrong, please help……..

    • Hi HAS,

      Stopping the pill pretty much universally leads to a delay in the body returning to a point in which it is ready for potential conception. The whole purpose of birth control pills is to prevent ovulation; the bleeding that takes place when you’re on the pill is just that, a “withdrawal bleed.” You may be “menstruating” in the strictest sense, but you haven’t actually ovulated (i.e. released an egg from the follicle to be potentially fertilized by sperm).

      Therefore, because of the way the pill works, when you’re coming off of it, your body needs to now adjust to life without the supplemental hormones the birth control provided. It can take weeks, up to even several months, for ovulation to naturally occur after stopping the pill.

      Going on a year without getting pregnant isn’t necessarily a cause for panic (although anxiety about it is very understandable), given that your reproductive system is adjusting to the fact that it’s now “on its own,” so to speak, and also, of course, given that ovulation is no longer being suppressed and your ovaries now need to re-start the egg release process.

      Granted, I have no idea what your medical history is, or what the particulars of your situation are; I would strongly suggest going to a physician to ask about ways to increase chances of conceiving, if you haven’t done so already. However, without trying to provide undue medical advice over the internet, just FYI, I do know that women with conditions such as PCOS or other reproductive issues that may adversely affect fertility are prescribed a medication called “Clomiphene” to help boost chances of pregnancy, and that it purportedly works very well. Perhaps you could ask your doctor about it when you get the chance.

      Hope this helped! Best of luck,


  4. hello, im on Yaz for one week. I started it on the first day of my period. Usually my period lasts for maximum 6 days, today its the 10th day and im still seeing some red and brown spots. im also havin back pain from my right side. why is this happening? is it normal?

  5. I’ve been on yaz for about four months going on five now, and I have PCOS and my doctor said taking yaz and metformin would help with me and my husband trying to get pregnant. We’ve been trying for over 2 years and after reading all the info about yaz, I’m not sure it sounds right. I had low estrogen levels and my doctor said it would help. Idk how true it can be tho..

    • you should try demulen .I had no periods for years and after one month of taking it I got pregnant. each case is different.

    • patricia smith says:

      Please see another gynecologist, preferably a female is familiar with the older birth control pills which generally have more research and patient data. As an older registered nurse who used low dose birth control pills for 25 years with regular check-ups I’m dismayed by the high rise of embolisms, heart problems etc.

  6. I would like to know one non hormonal alternative birth control method other than the “copper” IUD and abstinence that is as effective as oral or iud contraceptives? And i would also like to know the blood clot risks, if anyone has the data, differences between someone 25 and under compared to 25-35, and 35 and older because risk factor is also associated with lifestlye and age.

  7. Nicolene Taylor says:

    Dear Yaz, im lying in ICU confirmed that both my lungs are filled with boold clots? I have been on Yaz for 5months only. First time in my life im taking “the pill” at the age of 31?

    Why is it all over FB that Jaz is known for this? Take these pills off the market and safe aa life! !!!!!


  8. My Gyne recommended me to take YAZ (3 boxes) to help ease my acne breakout around chin area EVERY month each time I have my period (note that my period now reduce from 7-8 days to 3-4 days ever since I hit 39 years old ). Actually I wanted to check for my Hormone level but she says no need for it since I’m having regular period. I didn’t know that YAZ has more side effects than benefits. So now I’m in a dilemma to consume it or not since my 1st day of period is expected to be 2.5 wks from now. I’m so confused and don’t know what to do.

  9. Not mentioned but the World Health Organization has declared the the pill is a class 1 cancer causing agent! Have any of you been told this?

  10. My daughter was on Yazmin for 2 months ….she ended up in hospital with two clots on her lungs Thank God we got her to the hospital in time!

    • Know the feeling. Just been there, done that (refer comments in blog). My wife and l are absolutely horrified this product is still on the market.

  11. Just spent three days in hospital bedside with our (otherwise very healthy) daughter who now has blood clots in her lungs. Had been taking Yaz for seven months. Praise The Lord we got to it early. She is now recovering.

  12. Maria Lopez says:

    This product almost cause me to lose my life in 2009. I was on Yaz for 6 months and developed a DVT in my right leg and in turn caused bilateral pulmonary emboli. Both lungs were so full of clots they couldn’t count them all. A year after this I was taken off of Coumadin and had a reoccurrence of a superficial clot in my left leg. Went on self injections for several weeks then back on Coumadin. While on the drug several months later I got another clot in my lower left lung. So now, I am on xarelto probably for an extended amount of time. I say all of this to make everyone aware that I did not have any family history of clotting and Yaz caused a gene mutation (many extensive blood tests) that I will forever have. I am on a great health track now and have had no issues with blood clots for 4 years now. Yay!
    Stay away from Yaz and synthetic hormones! It almost destroyed my life!

  13. Omw. So shocked. Was on the 3 month injection for 13 yrs and dr said to leave it for yaz. Used it for 4 days. So confused right now. Do i stop it immediately and carry on with the injection? Plse help

  14. My ob prescribe me to take yaz for months.. I have a pcos and also 4months delayed without contact with sex.. After reading reviews I’m afraid to take yaz pills 🙁

  15. Melissa Chen says:

    Dear Yaz,
    May I know at what age I should stop taking Yaz.. I have been taking Yaz for more than 10 years and I am 47 years old now..Will Yaz increase the risk of heart attack?

  16. This is happening to my daughter and none of her doctors will listen to me. She WAS on Loryna for 2 months and is having all of the symptoms…numbness, chest pain, shortness of breath, etc. She has been to ER and elevated d-dimer but CT scan showed no blood clots, waiting for MRI results today. Her doctor is acting like we are crazy and not related to the birth control. What is the treatment for these symptoms? Is there any? No one has looked at her potassium levels or done blood work up.

  17. My dr just prescribed me Yaz today for my horribly painful periods and crazy mood swings. I can’t keep living my life like this every month! But after reading these replies I’m a bit scared to take it at all. ‍♀️

    • Me too – prescribed Today to help ease the heaviness which is likely the cause of my extreme iron deficiency…

      • im also anemic..i have low iron..i was presribed today but reading all the side effects is scaring me..are you taking the pills and how are you doing so far? pls let me know, thx.
