Tyvaso Patient Information Including Side Effects

Brand Names: Tyvaso, Tyvaso Refill Kit, Tyvaso Starter Kit

Generic Name: treprostinil inhalation (Pronunciation: tre PROS ti nil)

What is treprostinil inhalation (Tyvaso)?

Treprostinil works by dilating (widening) blood vessels in your lungs and by keeps the platelets in your blood from coagulating (clotting) to prevent unwanted blood clots. These effects lower blood pressure in the pulmonary artery that leads from your heart to your lungs.

Treprostinil is used to treat pulmonary arterial hypertension (PAH). It improves your ability to exercise and prevents your condition from getting worse.

Treprostinil may also be used for other purposes not listed in this medication guide.

What are the possible side effects of treprostinil inhalation (Tyvaso)?

Get emergency medical help if you have any of these signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.

Call your doctor at once if you have any of these serious side effects:

  • new or worsening PAH symptoms such as feeling short of breath (even with mild exertion), tiredness, chest pain, and pale skin;
  • feeling like you might pass out;
  • fever, chills, cough with yellow or green mucus, stabbing chest pain, wheezing;
  • unusual bleeding such as nosebleeds, bleeding gums, or any bleeding that will not stop;
  • pale skin, weakness, easy bruising;
  • unexpected vaginal bleeding;
  • blood in your urine or stools, black or tarry stools;
  • coughing up blood or vomit that looks like coffee grounds; or
  • swelling of your ankles or feet.

Less serious side effects may include:

  • cough, sore throat;
  • pain or irritation in your throat after use;

What is the most important information I should know about treprostinil inhalation (Tyvaso)?

Before using this medication, tell your doctor if you have a breathing disorder such as asthma or COPD (chronic obstructive pulmonary disease), an infection in your lungs (including pneumonia), low blood pressure, liver or kidney disease, or a bleeding or blood clotting disorder.

Treprostinil inhalation should be used only with a Tyvaso inhalation system. The inhalation system comes with patient instructions for safe and effective use. Do not use the medication at home if you do not fully understand how to use the inhalation system and properly clean it daily. Ask your doctor or pharmacist if you have any questions.

The effects of treprostinil inhalation will lessen over time between doses. Talk with your doctor if you need to time your dosing around any planned activities.

It is important to use treprostinil regularly to get the most benefit. Get your prescription refilled before you run out of medicine completely. Make sure you have a backup inhalation system available so as not to interrupt your treatment if one system stops working.

Call your doctor if your symptoms do not improve or if they get worse.
