Bayer also found itself under scrutiny for deceptive claims made while marketing Yaz.
In 2008, the FDA said that Yaz was shown not to be effective for common premenstrual symptoms, just a rare and serious form of them and that Yaz’s success was misleadingly overstated.
In fact, the FDA sent Bayer a warning letter, citing the company for running two false and misleading television ads about Yaz.
According to the letter, the ads overstated the drug’s efficacy, promoted it for conditions like a premenstrual syndrome for which the drug is not approved and minimized serious risks associated with the drug.
In February 2009, Bayer agreed to spend $20 million on a corrective advertising campaign to counteract misimpressions created by the original television spots – a lot of money to correct something Bayer either knew or should have known from the beginning.
Instead, recent studies have shown that this marketing was not only misleading but also dangerous.
These independent studies have found that Yaz carries higher blood clotting risks than other leading birth control pills.
While all birth controls come with some risk, Yaz is unique in that it contains a hormone called drospirenone that some experts believe may trigger more blood clots than other birth control pills because of elevated levels of potassium in the body.
In March 2011, Bayer announced the results of a large study that offers insight into the increased risk of venous thromboembolism (VTE), or blood clots, when using the Pill.
The study notes that the risk of a blood clot is highest during the first year of using the combination oral contraceptives (COC’s such as Yaz), and even higher in the first six months of use, as well as greatest when restarting the same or a different Pill after a four week or greater break.
In October 2011, the FDA released the results of a study of 800,000 women that found women taking Yaz had a 75% greater chance of experiencing a blood clot than women taking the older birth control pills.
In addition, BMJ released its own study of 1.2 million Danish women studied over eight years which concluded that women who took birth control pills that contain drospirenone (such as Yaz) were at least twice the risk of venous thromboembolism compared with users of older birth control pills.
As the risks associated with Yaz came to light, one had to question the integrity of Bayer’s original studies that found no increased risks.
Additionally, in a controversial Yaz FDA Advisory Panel meeting, there were reports of professional conflicts of interests and irregularities in the panel’s decision.
Where did Bayer draw the line between corporate interests and patients safety?
In France, Bayer found themselves involved in yet another birth control controversy in France when the National Security Agency for Medicines and Health Products (“ANSM”) announced birth control, Diane-35 would no longer be sold.
An investigation was also launched into Méliane, another of the newer generation contraceptives manufactured by Bayer.
Melanie has also been linked to life-threatening blood clots.
As always, if you or family members are considering birth control options, please consult with your doctor when making the decision that is right for you.
