Symptoms

The symptoms of PAH may make doing activities like walking to the mailbox, taking a short stroll, or walking up stairs, difficult.

Because vessels in the lungs constrict and less blood is able to flow through them to the rest of the body, certain symptoms occur, such as shortness of breath, fatigue, and dizziness. These symptoms may get worse as the disease progresses, so it's important to talk to your doctor regularly about the symptoms you’re experiencing to see if adding Tyvaso could be right for you.

  • Dizziness—this may happen when doing simple things like standing or climbing stairs because not enough oxygen is in the blood
  • Swollen face—caused by abnormal build-up of fluid in facial tissue
  • Fainting—can happen when your brain isn't getting enough oxygen. It is caused by reduced blood flow due to PAH. Let your doctor know immediately if you experience fainting spells
  • Cough—sometimes with blood
  • Hoarseness when talking—may be caused by enlarged vessels in the lungs pressing on a nerve
  • Chest pain—caused by not having enough oxygen in the blood
  • Shortness of breath—this is usually one of the first symptoms of PAH and is experienced upon slight exertion
  • Feeling tired or worn out—caused when not enough oxygen is getting into the blood and to other parts of the body
  • Swollen ankles and feet—caused by abnormal build-up of fluid in tissue
