Sildenafil (Liqrev, Revatio) is used to improve the ability to exercise in adults (Liqrev, Revatio) and children 1 year of age and older (Revatio) with pulmonary arterial hypertension (PAH; high blood pressure in the vessels carrying blood to the lungs, causing shortness of breath, dizziness, and tiredness). Sildenafil is in a class of medications called phosphodiesterase (PDE) inhibitors. Sildenafil treats erectile dysfunction by increasing blood flow to the penis during sexual stimulation. This increased blood flow can cause an erection.

Further information

This will allow your doctor to see if the medicine is working properly and to decide if you should continue to take it. If you take sildenafil for pulmonary arterial hypertension, do not take Viagra®, Vibrique™ or other PDE5 inhibitors, including tadalafil (Cialis®) or vardenafil (Levitra®). If you take too much sildenafil or take it together with these medicines, the chance for side effects will be higher. It is important to tell your doctor about any heart problems you have now or may have had in the past. This medicine can cause serious side effects in patients with heart problems. Sildenafil treats PAH by relaxing the blood vessels in the lungs to allow blood to flow easily.
