Pulmonary Arterial Hypertension Medications
Phosphodiesterase Type 5 Inhibitors: Sildenafil (Revatio®), Tadalafil (Adcirca®)

Your medicine is called _________________________________

Sildenafil (Revatio®), and/or tadalafil
(Adcirca®) are used to treat a condition
called Pulmonary Arterial Hypertension
(PAH). These are medicines are taken by
mouth (orally). They work by causing blood
vessels in the body to open up or “dilate”.
Dilating blood vessels helps to decrease the
overall pressure in the blood vessels.
Decreasing pressure in the pulmonary
arteries helps to decrease the amount of
work that the right side of the heart has to do
to pump blood through the rest of the body.
It may help delay or prevent heart failure.
Both men and women with PAH can use this
type of medicine as long as they have no
other medical reasons that would prevent
them from using it.

If any of the information in this leaflet
causes you special concern or if you want
more information about your medicine and
its use, check with your doctor, pharmacist
or nurse.

Remember to keep this and all other
medicines out of the reach of children.

avoided when using this medicine.

If you have chest pain and seek medical help
