Adverse effects
- Since treprostinil is a vasodilator, its antihypertensive effect may be compounded by other medications that affect the blood pressure, including calcium channel blockers, diuretics, and other vasodilating agents.[9]
- Because of treprostinil's inhibiting effect on platelet aggregation, there is an increased risk of bleeding, especially among patients who are also taking anticoagulants.[9]
Common side effects depending on route of administration:
- 85% of patients report pain or other reaction at the infusion site.[9]
