A 2010 report by the medical journal Reactions describes the case of a 20-year-old woman, otherwise in good health, who suffered a heart attack while taking an oral contraceptive containing the chemical drospirenone, found in contraceptives such as YAZ®.

The case of this woman, holding no risk factors for blood clot or heart attack other than the consumption of drospirenone-containing oral contraceptives, warranted the following comment from the author: “We consider that the use of the contraceptive pill contributed significantly to the thromboembolic event described here.”[1]  (Thromboembolic event means blood clot.) Thankfully, the woman recovered.[2]

Though this article does not provide explicit biological evidence of how drospirenone-containing contraceptives produce increased risk to users of blood clot, this publication may be used by a Yaz lawyer to illustrate one simple case of the undue dangers drospirenone use may pose.
