What is Revatio?

Revatio contains sildenafil citrate and is prescribed to treat pulmonary arterial hypertension (PAH) as well as improving the exercise capacity in people. PAH is a result of high blood pressure in the blood vessels which carry blood into your lungs. This can cause shortness of breath, dizziness and tiredness. Sildenafil Citrate works by relaxing the muscles of your blood vessels in order to increase blood flow around your body. By decreasing high blood pressure in your lungs, your heart and lungs can work more effectively which improves your ability to exercise.

Always read the medication information and instructions before using this medication.
Always follow your doctor’s directions.

  • Revatio may be taken with or without food and is typically taken three times a day, six hours apart.
  • Do not take more than your doctor’s recommended dose. Taking more of this medication or taking it more frequently will not improve your condition any quicker but it may increase your risk of side effects.
  • Revatio is most effective when taken regularly. Try to take this medication at the same time every day.
  • Speak to your doctor if your condition does not improve.


Make sure to tell your doctor:

  • If you have any drug or other allergies.
  • If you take any other prescription or over-the-counter medications.
  • Your medical history especially of blood problems, blood cell disorders, heart problems, high or low blood pressure, stroke, liver disease, stomach disease, stomach ulcer, dehydration, retinitis pigmentosa or blindness in one or both eyes.
  • If you have been told not to have sex for medical reasons or if you have ever had an erection which was painful or lasted over four hours.
  • If you have any penis conditions including angulation, fibrosis, scarring or Peyronie’s disease.
  • If you are pregnant or planning pregnancy.
  • If you are breast-feeding.

Other information you should also know:

  • Taking alcohol or marijuana while taking Revatio can increase the risk of side effects. Limit your amount of these substances or speak to your doctor for more information.
  • Revatio may cause vision problems or dizziness. You should not drive or do any other activity which requires alertness until it can be done safely.

What is the difference between Revatio and Viagra?

Both Viagra and Revatio contain the active ingredient sildenafil and increase blood flow around the body by relaxing your muscles. However, Revatio and Viagra are prescribed for different conditions and come in different strengths. Revatio only comes in a 20mg strength while Viagra is available in 25mg, 50mg and 100mg. You should not take both medications and should only take what your doctor prescribes for you.

Who can take Revatio?

Revatio can be used by both men and women above the age of 18 when prescribed by a doctor.

The medication to treated SIBO in the USA is absolutely over priced as it has to be used usually twice a year. True Canada Pharmacy helped me obtain 2+ treatment doses of it for far, far, far less than 1 treatment dose cost in the USA. Due to the pandemic it takes a while to get it but we are all set for the next time it recurs. Thank you so very much.

I have used Canadian Pharmacy for at least 10-12 years. I have been very grateful to be able to get my life saving scripts at reasonable affordable prices. The follow-up of your Reps is excellent. During the COVID 19 virus outbreak scripts took much longer to receive. I think thus was partly due to the U.S.P.S. assault by DeJoy as Postmaster General. Before COVID 19 it took approx. 2-3 weeks to receive meds; during COVID 19 and the US General Election year, it took easily 2 months to receive scripts. It will be interesting to see if future orders arrive any more quickly after DeJoy is no longer Postmaster General?!

Good experience. I found another pharmacy with a lower price than yours, and you did lower the price for me. It took some time to get everything straight, so you expedited the mail and I received it on time. Thank you.
