Tyvaso DPI

Generic name: Treprostinil
Drug class: Agents for pulmonary hypertension

Usage of Tyvaso DPI

Treprostinil inhalation is used to treat the symptoms of pulmonary arterial hypertension (PAH) and pulmonary hypertension with interstitial lung disease (PH-ILD) to improve exercise ability. PAH is the high blood pressure that occurs in the main artery that carries blood from the right side of the heart (the ventricle) to the lungs. When the smaller blood vessels in the lungs become more resistant to blood flow, the right ventricle must work harder to pump enough blood through the lungs. Treprostinil works by blocking a hormone (a naturally occurring substance), that is found in the blood and lungs in large quantities of the people with pulmonary arterial hypertension.

This medicine is available only with your doctor's prescription.

Before taking Tyvaso DPI

Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals.

Pediatric

Appropriate studies have not been performed on the relationship of age to the effects of treprostinil inhalation in the pediatric population. Safety and efficacy have not been established.

Geriatric
