  • History of clinically relevant allergy or known hypersensitivity to DRSP/EE
  • Clinically relevant findings on the mammae or genital examination, PAP smear ≥ III
  • Any contraindications against the oral contraceptive:
  • present or past venous thromboses (deep vein thrombosis, pulmonary embolism);
  • present or past arterial thromboses (e.g. myocardial infarction) or their prodromal stages (e.g. angina pectoris and transitory ischaemic attack);
  • present or past cerebrovascular insult;
  • presence of a serious risk factor or several risk factors for an arterial thrombosis: diabetes mellitus with vascular changes, severe hypertension, severe lipid metabolism disturbance;
  • known or suspected genetic or acquired predisposition for venous or arterial thromboses like APC resistance,
  • known or suspected genetic lack of antithrombin III, lack of protein C, lack of protein S, hyperhomocysteinaemia and antiphospholipid antibodies (anticardiolipin antibodies, lupus anticoagulants);
  • present or past pancreatitis if this is accompanied by severe hypertriglyceridaemia;
  • present or past severe hepatic disease as long as the liver function tests have not normalized;
  • severe renal insufficiency or acute renal failure;
  • present or past hepatic tumors (benign or malign);
  • known or suspected sexual hormone dependent, malign tumors (e.g. of the genital organs or the mamma);
  • diagnostic not clarified vaginal bleedings;
  • anamnesis of migraine with focal neurologic symptoms;
  • known hereditary angioedema
  • Exposure to another investigational agent within the last two months before Day 1 of Period 1
