Yaz, known generically as drospirenone, is a birth control that works by changing the uterine and cervical lining, and is 99.9 percent efficient at preventing pregnancy. Bayer HealthCare Pharmaceuticals has manufactured and distributed Yaz in the United States since it was approved by the FDA in 2001. Women who have taken Yaz have reported side effects that range from mild to severe. Any woman thinking of taking this drug should:

•    Discuss their complete medical history with their physician before using Yaz
•    Be completely aware of any risks associated with taking Yaz, and recognize symptoms of serious side effects
•    Seek medical attention if there are any signs or symptoms of dangerous Yaz side effects
•    Know your legal rights, because any harmed individual with a legitimate claim could be entitled to compensation.

Yaz Side Effect: Bleeding
The hormones in Yaz alter women's menstrual cycle. At the beginning of usage it causes fluctuations and may cause their menstrual cycles to become abnormal, and may cause:

•    Breakthrough bleeding
•    Early or late peroids
•    Longer periods
•    Spotting

Within a few months, once the body has the time to adjust, these side effects could fade away and periods will once again go back to being normal. Women who have a history of abnormal bleeding should not take Yaz, because they are at an increased risk of developing life-threatening Yaz side effects such as liver impairment, blood clots, stroke and/or pulmonary embolism.

Bleeding During Inactive Pills
There are 28 pills, in total, in a package of Yaz. Four of these pills are what's called a placebo, where as the other 24 contain hormones. These hormones cause the uterine lining to shed, causing menstruation. The bleeding passes during the use of the inactive pills (placebos). Many women's periods fluctuate during their first intake of Yaz birth control pills. However, in following months the body will align itself as it becomes accustomed to the hormone dose, and menstruation will become normal once again.

If Yaz Breakthrough Bleeding Persists
Any woman who has taken Yaz should get a through exam. Minor side effects, like breakthrough bleeding, could be an indication of more critical Yaz side effects. Women who took Yaz and experience any negative side effects should consider switching forms of birth control, but those who sustain severe Yaz side effects need to look into filing a claim against Bayer HealthCare. It is important to find a defective drug attorney that is both experienced with Yaz claims and will help you.
