  • Use within 1 month of an sildenafil or vardenafil
  • WHO functional class IV status
  • Patients with severe other organ disease felt by investigators to impact on survival during the course of the study
  • Subjects with liver function abnormalities (ALT or AST > 3 times the upper limit of normal at screening or at baseline) or chronic liver disease
  • Advanced kidney failure (GFR < 30 ml/min at screening or at baseline)
  • History of hypersensitivity reaction or adverse effect related to tadalafil
  • Pregnant or lactating women
  • Concomitant use of nitrates (any form) either regularly or intermittently
  • Concomitant use of potent CYP3A inhibitors (eg, ritonavir, ketoconazole, itraconazole)
  • Any additional contraindications and precautions specified in the package inserts for Tadalafil (Adcirca) not listed above
