Warnings and precautions

Hematologic: Treatment with OPSUMIT has been associated with a decrease in hemoglobin concentration. Decreases occurred early, were not progressive, and stabilized before 12 weeks. Cases of anemia requiring transfusion have been reported. Initiation of OPSUMIT is not recommended in patients with severe anemia. Hemoglobin concentrations should be measured prior to initiation, after one month, and periodically thereafter. Hepatic/Biliary/Pancreatic: Elevations of liver aminotransferases (AST, ALT) have been associated with PAH and endothelin receptor antagonists (ERAs). OPSUMIT is not to be initiated in patients with elevated aminotransferases (>3 x ULN) at baseline and is not recommended in patients with moderate to severe hepatic impairment. Liver enzyme tests should be obtained prior to initiation, monthly during the first year, and less frequently thereafter. If unexplained clinically relevant aminotransferase elevations occur, or if elevations are accompanied by an increase in bilirubin >2 x ULN, or by clinical symptoms of liver injury (e.g. jaundice), OPSUMIT treatment should be discontinued. Re-initiation may be considered after hepatic enzyme levels return to normal in patients without clinical symptoms of liver injury. Pulmonary Veno-Occlusive Disease: Cases of pulmonary edema have been reported with vasodilators in patients with pulmonary veno-occlusive disease. If signs of pulmonary edema occur when OPSUMIT is administered in patients with PAH, the possibility of pulmonary veno-occlusive disease should be considered. Renal: Patients with moderate or severe renal impairment may run a higher risk of experiencing hypotension and anemia. Monitoring of blood pressure and hemoglobin should be considered. OPSUMIT is not recommended in patients undergoing dialysis. Reproductive Health: Based on animal findings, OPSUMIT may impair fertility in males. Decreases in sperm cell count have been observed with ERAs. Counsel men about potential effects on fertility. OPSUMIT is teratogenic in rabbits and rats. Women of child-bearing potential must have pregnancy verified before initiation, use reliable contraception, and not become pregnant for 1 month after discontinuation. Monthly pregnancy tests are recommended.
