Revatio (sildenafil)

Revatio (sildenafil) is used to treat pulmonary hypertension (high blood pressure in the blood vessels between the heart and lungs) when people have not responded to conventional treatment. It helps reduce pulmonary blood pressure by widening blood vessels. It may also be used for other conditions as determined by your doctor.

The recommended dose of sildenafil for pulmonary hypertension is 20 mg three times daily, approximately 6 to 8 hours apart. It can be taken with or without food.

Revatio (sildenafil) is a phosphodiesterase inhibitor. It works by relaxing blood vessels in the lungs, which decreases blood pressure.

If you miss a dose, take it as soon as possible and continue with your regular schedule. If it is almost time for your next dose, skip the missed dose and continue with your regular dosing schedule. Do not take double doses to make up for a missed one.
