According to a story Monday in the New York Post, Hamilton had no underlying health issues or any history of health problems at the time. She had been using Yasmin for two years when she suffered the effects of what she described as a "terrifying" stroke in May 2007.
Hamilton is not alone in her litigation. There are more than 1,100 lawsuits against Bayer, the Germany-based manufacturer of Yasmin birth control and its cousin Yaz, alleging serious and life-threatening health problems. Bayer continues to defend the safety and efficacy of Yasmin, touting estrogen levels that are lower than other classes of oral birth control pills.
High levels of estrogen have reportedly caused blood clots and strokes in women taking older forms of oral contraceptives, the New York Post notes.

That was in 2008—a year after Hamilton became ill.
Hamilton, who is now fully recovered, claims in her lawsuit that Bayer knew that Yasmin posed a risk for blood clots and strokes, but withheld the information from patients and healthcare providers.
"I'm pretty angry that this happened to me," said Hamilton. "I was 27 at the time. I don't think this should be happening to young women. It shouldn't happen to any woman just because they take birth-control pills."
Bayer brought in $1.5 billion from sales of Yasmin birth control in 2009.
