Treprostinil Injection

What is this medication?

TREPROSTINIL (tre PROST in il) treats pulmonary arterial hypertension (PAH), a condition that causes high blood pressure in the lungs. It works by relaxing your blood vessels and lowering the blood pressure in your lungs, which makes it easier for your heart to pump blood to the rest of your body. It can also help you breathe easier and be more active.

This medicine may be used for other purposes; ask your health care provider or pharmacist if you have questions.
