Elmiron Disease Interactions

Pentosan polysulfate sodium induces weak anticoagulant activity (1/15 the activity of heparin). Bleeding complications (ecchymosis, epistaxis, bleeding gums) have occurred. Increases in PT and PTT, as well as thrombocytopenia, have been reported rarely. Therapy with pentosan polysulfate sodium should be administered cautiously in patients with coagulation disorders, bleeding, or other conditions that may increase the risk for bleeding.

The use of pentosan polysulfate sodium has not been studied in patients with hepatic insufficiency. Because there is evidence of hepatic contribution to the elimination of this drug, hepatic impairment may have an impact on its pharmacokinetics. Caution should be exercised when using pentosan polysulfate sodium in this patient population.
