Treprostinil Diolamine

Pronounced

"tre-PROS-ti-nil"

Uses

This medication is used to treat a type of high blood pressure in the lungs (pulmonary arterial hypertension). Treprostinil helps to delay disease worsening and increase your ability to exercise. It works by relaxing and widening the blood vessels (arteries) in the lungs and other parts of the body so that blood can flow more easily. This medication belongs to a class of drugs known as vasodilators.

Take this medication by mouth with food as directed by your doctor, usually twice daily (every 12 hours) or three times daily (every 8 hours).

Swallow the medication whole. Do not crush or chew the tablets or use a tablet that is damaged or broken. Doing so can release all of the drug at once, increasing the risk of side effects.
