This medicine helps treat high blood pressure in the lungs, making blood flow easier and reducing the heart's workload.
Your doctor will decide the right dose for you based on your health.
This medicine is given continuously through a small tube (cannula) placed under your skin in your stomach or thigh, or into a vein in your neck, chest, or groin. A portable pump outside your body pushes the medicine through the tube.
Do not change your dose or increase it without talking to your doctor. Your doctor will set your maximum daily dose.
