Helpful Resources

A number of online resources are available for people living with pulmonary arterial hypertension (PAH). The links below provide additional education, resources, and support.

Emotional and Practical Support

PEER Network

If you are a PAH patient who is considering Tyvaso or has already started Tyvaso, the PEER Network may be for you. Through the PEER Network, new patients can connect with someone who is already taking Tyvaso. Experienced Tyvaso patients volunteer their time to share lifestyle information and provide emotional support to help new patients. United Therapeutics sponsors the PEER Network so that new patients can have private, one-on-one communication to learn more about what it's really like to take Tyvaso.

Tyvaso is a prescription medicine used in adults to treat pulmonary arterial hypertension (PAH) (WHO Group 1), which is high blood pressure in the arteries of your lungs.

The effects of Tyvaso are unknown in patients under 18 years of age.
