Hypotension.Adempas reduces blood pressure. Consider the potential for
symptomatic hypotension or ischemia in patients with hypovolemia, severe left
ventricular outflow obstruction, resting hypotension, autonomic dysfunction,
or concomitant treatment with antihypertensives or strong CYP and P-gp/BCRP
inhibitors. Consider a dose reduction if patient develops signs or symptoms of

occurred in 2.4% of patients taking Adempas compared to 0% of placebo
patients. Serious hemoptysis occurred in 5 (1%) patients taking Adempas
compared to 0 placebo patients, including one event with fatal outcome.
Serious hemorrhagic events also included 2 patients with vaginal hemorrhage, 2
with catheter site hemorrhage, and 1 each with subdural hematoma, hematemesis,
and intra-abdominal hemorrhage.

Pulmonary Veno-Occlusive Disease. Pulmonary vasodilators may significantly
worsen the cardiovascular status of patients with pulmonary veno-occlusive
disease (PVOD). Therefore, administration of Adempas to such patients is not
recommended. Should signs of pulmonary edema occur, the possibility of
associated PVOD should be considered and if confirmed, discontinue treatment
with Adempas.
