Yaz and liver

My sister at 39 years old recently died from the condition called pulmonary thromboembolism caused by the use of Yaz. Please if you are taking this pill and are experiencing anything negative from it, get off of it immediately. I am currently seeking legal counsel for my sisters death, I believe it is unfair that a product like this can take a human life, and no-one will be held liable. I have been told that it will be virtually impossible to bring a lawsuit against a product that has been FDA approved. My sister left behind three children who love, miss and still needed her. If anyone can give me some type of direction on how to bring a lawsuit against the manufacturer of this product please contact me asap.

I posted for my 14 year old daughter a couple of weeks ago. I am happy to say that we stayed off of the YAZ after going to the hospital 2 times, sonograms, cat scans.... worried about spleen rupture ~ pains in the side, back, shoulder, throwing up THE WHOLE SHABANG! pretty much every side effect there is listed for this horrible drug she had. Well...turns out she had mono/epstein barr a couple of months ago so it kicked it up again after it was getting better. DOCTORS PA's....push push push meds. We need to be more informed about what we take into our bodies. MEN WOMEN CHILDREN just because they prescribe it doesn't mean we should take it. we are the guinnea pigs here. Yes there will probably be a law suit and it will like the patch be taken off of the market. But where will we be??
So my thought on this drug is that doctors need to be taking blood tests of a variety of things before saying ~ yes it is ok for you to take this. Because there are some (I say SOME) people who aren't as sick as others... some people drink booze so their liver will be elevated some people have dormet problems that will cause this pill to reek havoc on your system... everyone needs to get a grip on taking meds.... it is whats causing havoc on our bodies. we take all these pills. its crazy.
