What is treprostinil (Remodulin)?

How treprostinil (Remodulin) works

Treprostinil (Remodulin) is a prostacyclin analog, which means that it acts like prostacyclin. Prostacyclin is a natural hormone in your body that helps widen or open up the blood vessels leading to your lungs from your heart. This allows blood to flow better in the lungs, which lowers blood pressure in the lungs, helps your body get more oxygen, and helps the heart work more efficiently.

What is treprostinil (Remodulin) used for?

What are the risks and warnings for treprostinil (Remodulin)?

Treprostinil (Remodulin) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options

Bloodstream infections

  • Risk factors: Infusing treprostinil (Remodulin) into a vein

Infusing treprostinil (Remodulin) into your vein for a long time can potentially cause bloodstream infections. These infections can be life-threatening. To lower your risk of infections, wash your hands before using treprostinil (Remodulin), and make sure the area by your catheter is clean and pain-free. Infusions delivered underneath your skin is preferred, because there is a lower risk of bloodstream infections when the medication is delivered this way.

Worsening of PAH symptoms

Your symptoms of PAH can worsen if you lower your dose or stop taking treprostinil (Remodulin) suddenly. Make sure you have a backup infusion pump in case your pump stops working during administration.

Let your healthcare provider know if you have a history of liver or kidney problems before you start treprostinil (Remodulin), so they can prescribe you a safe dose.
