What is Tyvaso?

TYVASO (treprostinil) is a prescription medicine used in adults to treat pulmonary hypertension associated with interstitial lung disease (PH-ILD; WHO Group 3), which is high blood pressure in the lungs due to inflammation and sometimes scarring in the lungs. TYVASO can improve the ability to exercise.

IMPORTANT SAFETY INFORMATION

Before you take TYVASO, tell your healthcare provider about all of your medical conditions, including if you:

  • Have low blood pressure
  • Have bleeding problems
  • Are pregnant or plan to become pregnant. It is not known if TYVASO will harm your unborn baby.
  • Are breastfeeding or plan to breastfeed. It is not known if TYVASO passes into your breast milk. Talk to your healthcare provider about the best way to feed your baby during treatment with TYVASO.

Tell your healthcare provider about all the medicines you take, including prescription and over-thecounter medicines, vitamins, and herbal supplements. TYVASO and other medicines may affect each other.

Especially tell your healthcare provider if you take:

  • Medicines used to treat high blood pressure or heart disease
  • Medicines that decrease blood clotting (anticoagulants)
  • Water pills (diuretics)
  • Gemfibrozil (Lopid®) or rifampin (Rimactane®, Rifadin®, Rifamate®, Rifater®)

What are the possible side effects of Tyvaso?

Tyvaso can cause serious side effects, including:

  • Low blood pressure (symptomatic hypotension). If you have low blood pressure, Tyvaso may lower your blood pressure more.
  • Bleeding problems. TYVASO may increase the risk of bleeding, especially in people who take blood thinners (anticoagulants).

The most common side effects of TYVASO are cough, headache, throat irritation and pain, nausea, reddening of the face and neck (flushing), fainting or loss of consciousness, dizziness, and diarrhea. These are not all the possible side effects of TYVASO. Call your doctor for medical advice about side effects.

You may report side effects to the FDA at www.fda.gov/MedWatch or call 1-800-FDA-1088.
