You May Have Side Effects

The most common side effects of TYVASO are cough, headache, throat irritation and pain, nausea, reddening of the face and neck (flushing), fainting or loss of consciousness, dizziness, and diarrhea. These are not all the possible side effects of TYVASO.

Don’t let side effects stop you from getting the benefits of your medicine. It’s important to talk to your healthcare provider and continue taking TYVASO unless told to stop. Be sure to contact your nurse about things you can do to help manage side effects while continuing treatment, such as:


Keep the device level and take normal breaths during treatment, and avoid holding your breath once you inhale. If needed, use a throat spray to numb your throat before treatment.


Eat a small meal before treatment. Try taking an over-the-counter antidiarrheal. Rinse your mouth with water after treatment.


Use an over-the-counter pain reliever, like acetaminophen. Talk to your doctor to see if slowing the pace at which you increase your dose could help.


Talk to your doctor about any side effects you may be experiencing. Do not stop taking TYVASO without direction from your doctor.

These tips may help you manage common side effects with TYVASO, based on healthcare provider experience. You should not think of this as medical advice.
