In fairness, Factor 5 Leiden is probably more to blame than the pill in that case. Prothombrin disorders are deadly, with or without the pill.
As a Factor 5 myself, I understand the risk of the disease by itself. However, the death was directly related to the higher intensity of the risk due to the Pill.
Would she have died without taking the pill anyway? Perhaps, but hers is not even remotely an isolated story. When I see the advertisements for Yaz and all similar drugs, I wait for the disclaimers about blood clots and the such (and that’s for people without factor 5, as well).
Given that factor 5 is genetically inherited, you’d think no responsible parent, no responsible doctor, and no responsible pharmacist would allow birth control to be prescribed without a DNA workup of some sort. Blood clots are like time bombs. The pill is the match that lights the fuse prematurely.
