Birth control drugs Yasmin, Yaz and Ocella associated with serious side effects including death

Yasmin and YAZ are two varieties of combination type birth control pills (BCP) produced by Bayer Healthcare. Yasmin was approved for sale in the US by the FDA in 2001 while YAZ was approved in 2006. Both YAZ and Yasmin contain 3 mg of drospirenone, a progestin, which is combined with 30 mcg of ethinyl estradiol in Yasmin and 20 mcg of this estrogen in YAZ. The estrogen component of these BCPs has been in common use since the 1970s. Drospirenone is a relatively new fourth generation progestin which has been shown to have an anti mineralocorticoid effect. This effect leads to diuresis, (increased urination) while retaining potassium which can lead to elevated serum potassium levels (hyperkalemia). It is suspected that this progestin is the cause of a notable increase in certain adverse effects which include death, arrhythmias, venous and arterial blood clots, gallbladder disease, pancreatitis, liver or kidney failure, dehydration and hypertension. The serious cardiovascular side effect are markedly increased in those who smoke and with advancing age particularly beyond age 35.

YAZ had been approved for birth control, for women who suffered from premenstrual dysphoric disorder PMDD (a markedly depressed mood, anxiety or tension affective lability and persistent anger or irritability) and for the treatment of moderate acne vulgaris in women who also desire pregnancy prevention. The advertising in question seemed to give the message that YAZ was indicated for PMS ( a much milder constellation of symptoms than PMDD) and all severities of acne rather than the specific approved indications. The FDA also sent a warning letter to correct misleading advertising to Berlex labs, the original producer of Yasmin in 2003. Bayer acquired the rights to market Yasmin in 2006. In February of 2009 Bayer settled with the FDA and the attorneys general of 27 states to mount a $20,000,000 campaign to correct the misconceptions it had created. The corrective ads ran from February through late July 0f 2009. During the period of ads labeled misleading by the FDA, YAZ sales nearly tripled from the 262 million in 2007 sales.
