Instructions For Use
Helping your patients to keep track of their 4 times daily dosing is vital to their PAH treatment success. In the patient’s initial shipment
from their
Specialty Pharmacy Service provider, they’ll receive the Tyvaso® Treatment Tracker. This
tool is designed to help patients track the number of breaths they take during each treatment session.

The treatment tracker is a monthly, pocket-size personal diary that allows patients to record treatment sessions. The diary consists of daily calendars organized by week. Each day, patients will check 1 circle for every breath of Tyvaso taken during individual treatment sessions. For example, if you prescribe 9 breaths (3 cycles) of Tyvaso per treatment session, your patient will need to make sure to record their breaths after each cycle (3 breaths) and check 9 circles (for 9 breaths) 4 times each day.
It is important to remind your patients that 3 breaths equals 1 cycle.
Tyvaso is a prostacyclin vasodilator indicated for the treatment of pulmonary arterial hypertension (PAH) (WHO Group 1) to improve exercise ability. Studies establishing effectiveness included predominately patients with NYHA Functional Class III symptoms and etiologies of idiopathic or heritable PAH (56%) or PAH associated with connective tissue diseases (33%).
The effects diminish over the minimum recommended dosing interval of 4 hours; treatment timing can be adjusted for planned activities.
While there are long-term data on use of treprostinil by other routes of administration, nearly all controlled clinical experience with inhaled treprostinil has been on a background of bosentan (an endothelin receptor antagonist) or sildenafil (a phosphodiesterase type 5 inhibitor). The controlled clinical experience was limited to 12 weeks in duration.
