People all over the country are filing lawsuits against the manufacturer of the birth control pills Yaz and Yasmin.  The plaintiffs allege that Yaz concealed health risks associated with the pills and lied about their effectiveness.   The plaintiffs further allege that drospirenone, a diuretic, causes an increase in potassium which can lead to bhyperkalemiab b an unsafe level of potassium that disrupts heart rhythms and slows the flow of blood, leading to clotting.  If you have taken Yaz or Yasmin and recently had a stroke, heart attack or blood clots, please contact Vanden Heuvel & Dineen, S.C.
