What is Revatio?

Revatio contains the medication sildenafil and is prescribed for people with pulmonary arterial hypertension (PAH) to improve their ability to exercise. Pulmonary arterial hypertension is high blood pressure in your lungs and Revatio works by relaxing and widening the blood vessels within your lungs. This allows blood to flow more easily allowing your heart and lungs to work better, improving your ability to exercise.

Make sure to always read the patient information and instructions before using this medication. Always Follow your doctor’s directions.

  • Revatio should be taken by mouth and can be taken with or without food.
  • It is typically taken three times a day, between four and six hours apart. Always follow your doctor’s directions.
  • This medication is most effective when taken regularly. Try to take it at the same time each day.
  • Tell your doctor if your condition does not improve.


Tell your doctor and pharmacist:

  • About your drug and other allergies.
  • If you take any other prescription or over-the counter medications.
  • Your medical history particularly of stomach ulcers, heart disease, kidney disease, liver disease, heart attack, irregular heartbeat, stroke, chest pain, high blood pressure, low blood pressure, high cholesterol, bleeding disorders, blood circulation problems, diabetes, blood cell problems, sudden vision loss, cancer or pulmonary veno-occlusive disease.
  • Your personal and family history of eye diseases.
  • If you have any condition of the penis such as Peyronie’s disease, cavernosal fibrosis or angulation.
  • If you have ever had an erection which was painful or lasted for several hours.
  • If you have ever been told to avoid sexual activity for medical reasons.
  • If you are pregnant, planning pregnancy or breast feeding.
  • If you smoke.
  • If you have recently suffered from dehydration.

You should also know:

  • You should not take any medications containing nitrates while taking sildenafil including ‘poppers’.
  • Sildenafil may cause dizziness or vision problems. Avoid driving or anything else requiring alertness until it can be done safely.

What is the difference between Revatio and Viagra?

Revatio and Viagra both contain sildenafil and work by relaxing muscles in order to increase blood flow. However, Revatio comes in 20mg which is a lower strength than Viagra which is available in 25mg, 50mg and 100mg. Revatio and Viagra are prescribed for different conditions and you should only use the medication which has been prescribed for you.
