Get answers to some of the most commonly asked questions about PAH, TYVASO DPI, and TYVASO.
STARTING TYVASO
What is prostacyclin-class therapy?
People living with PAH may not produce enough natural prostacyclin. TYVASO is a man-made form of prostacyclin, called a prostacyclin mimetic. It mimics some of the effects of the natural prostacyclin in the body, helping to keep the blood vessels in the lungs open and working properly.
What can I expect with TYVASO therapy?*
Adding TYVASO to your background oral medication, like bosentan (an ERA) or sildenafil (a PDE-5 inhibitor), could help improve your ability to exercise. Adding TYVASO may help you do more in your day—go for a stroll, walk your kids to the bus stop, or walk to a mailbox.
In a clinical study, people who added TYVASO to their PAH background therapy walked farther—improving their 6MWD† by 22 m at 12 weeks, with improvements seen in as soon as 6 weeks.‡

Individual results may vary.
6-minute walk distance (6MWD) is a test to see how far you can walk in 6 minutes.
In the 12-week clinical study of TYVASO, people taking an oral PAH medicine (bosentan or sildenafil) completed a 6-minute walk test at the beginning and end of the study.
How do I get TYVASO?
If you and your doctor agree that TYVASO could help you, a referral for your TYVASO prescription will go to a Specialty Pharmacy (SP) provider or United Therapeutics Cares™. Once approved, an SP nurse will come to your home or your doctor’s office to show you how to take TYVASO and will support you as you begin therapy.
What should I tell my doctor before starting TYVASO?
Before you take TYVASO or TYVASO DPI, tell your healthcare provider about all of your medical conditions, including if you:
- Have low blood pressure
- Have or have had bleeding problems
- Have asthma or chronic obstructive pulmonary disease (COPD)
- Are pregnant or plan to become pregnant. It is not known if either product will harm your unborn baby.

What is TYVASO DPI?
TYVASO DPI features the same medicine as the TYVASO nebulizer but in a dry powder inhaler. This small, portable inhaler uses cartridges and features a simple-to-use design.
How does TYVASO DPI dosing work?
Your doctor will work with you to increase your dose until you reach your target maintenance dose. This process is called “titration.”
Plan to take your medication approximately every 4 waking hours.
- Doses are taken with 1 breath per cartridge
- Most people start with the 16 mcg cartridge, 4x daily, and increase their dose every 1-2 weeks
How do I switch from the TYVASO nebulizer to TYVASO DPI?
Talk to your doctor to learn about switching to TYVASO DPI. In most cases, your doctor will prescribe the cartridge strength that equals the number of breaths you are currently taking with your TYVASO nebulizer.
How do I use TYVASO DPI?
TYVASO DPI uses cartridges and features a simple-to-use design. Taking a dose is as simple as just one breath—open, load, inhale.

Side Effects
What are the possible side effects of TYVASO or TYVASO DPI?
Both products can cause serious side effects, including:
- Low blood pressure (symptomatic hypotension). If you have low blood pressure, either product may lower your blood pressure more.
- Bleeding problems. Either product may increase the risk of bleeding, especially in people who take blood thinners (anticoagulants).
The most common side effects of both products are cough, headache, throat irritation and pain, nausea, reddening of the face and neck (flushing), fainting or loss of consciousness, dizziness, diarrhea, and shortness of breath. Like other inhaled prostaglandins, you may have trouble breathing after taking TYVASO or TYVASO DPI because it may cause the muscles around your airway to tighten (bronchospasm). These are not all the possible side effects. Call your doctor for medical advice about side effects or if you have trouble breathing.
Tell your doctor about any side effect that bothers you or does not go away.

Is there anything I should tell my doctor about the other medications I take?
TYVASO was added to treatment with other PAH medications in multiple studies.
Tell your healthcare provider about all of the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. Either product 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®)
Be sure to make a list of all the medicines (prescription and over the counter), vitamins, and herbal supplements you take routinely or even occasionally. Update the list as needed, keep it with you, and show it to your doctor and Specialty Pharmacy provider.
