How to Take Sildenafil 20 Mg for ED?

Erectile dysfunction or impotence is a condition characterized by the fact that you cannot obtain erection even with the presence of sexual stimulation. It is caused by lack of blood flow and too much PDE5 enzyme produced in the penile organ. To resolve this issue, a PDE5 enzyme inhibitor and a muscle relaxant are what you need. This is what sildenafil does. Sildenafil is the active formula used in manufacturing Viagra and other erectile dysfunction medicines.

The usual sildenafil dosage for ED is 25 mg (this is the lowest dosage available). However, Revatio, another sildenafil medicine, comes in 20 mg. Revatio is used in treating pulmonary arterial hypertension or PAH. Revatio is available in a 20 mg dose. The question is can you take sildenafil 20 mg to treat erectile dysfunction?

It is possible to use sildenafil 20 mg to treat erectile dysfunction but the process might take longer. In addition, instead of taking sildenafil as needed (on a regular dose), you might need to take it daily with Sildenafil 20 mg. At 20 mg, the dose is practically low and is not enough to give you your desired power. However, before taking sildenafil 20 daily for your ED, you best talk to your doctor first and tell them of your intention to take it daily.

Sildenafil 100mg How Long Does It Last?

Sildenafil 100mg is the highest available dosage of sildenafil tablet regardless of the brand. Its effect is known to last for 4 hours up to 6 hours. This is if it was taken properly and that you are in your best condition.

To maximize the effect of sildenafil 100mg, take it on an empty stomach. With an empty stomach, sildenafil will easily be digested and absorbed into the bloodstream. The effect will be quicker and you can be ready in as fast as 30 minutes after having it.

If there is a need to eat before taking this drug, eat a light meal. Do not eat fatty foods because it can delay the effect of this ED drug.

Although the effect of sildenafil is just up to 6 hours, it is not advisable to take another tablet after its power wears off. The maximum dosage that is recommended for sildenafil is 100 mg unless you have a special condition or your doctor gave you a thumbs-up for taking more than 100 mg within 24 hours.

Does Revatio Work Like Viagra?

Revatio Pack

The only sildenafil tablet that is available in 20 mg is Revatio. Revatio is a prescribed treatment for pulmonary arterial hypertension or PAH. This medicine contains sildenafil citrate just like Viagra. It also works as a PDE5 inhibitor and a muscle relaxant. The target of Revatio is the small blood vessels in our lungs. It aims to help these vessels relax and regulate blood flow properly to avoid arterial hypertension. Revatio is also a product of Pfizer.

Revatio is taken daily, as part of a PAH treatment. It is often prescribed to adults with PAH. The maximum dose is 20 mg, to be taken three times a day. Revatio is also available as an injectable. It is formulated in 2.5mg and 10mg IV bolus and it should be administered three times a day as well.

Revatio works like Viagra in a sense that it also helps regulate blood flow and relaxes affected muscles to improve blood flow. The only difference between the two is their formulated dosage and the way it should be taken. Here are some of their noteworthy differences:

  • The highest dose of Revatio is 20 mg and 100 mg for Viagra
  • A PAH patient can only take up to 60mg of Revatio a day while an ED patient can take up to 200 mg of sildenafil if needed
  • A PAH patient can take Revatio three times a day while an ED patient can take one Viagra tablet only within 24 hours
  • PAH patients are expecting for the long-term effect of Revatio (preventing arterial hypertension) while ED patients are expecting immediate effect from Viagra (in 30 to 45 minutes).
  • The lowest dose for Viagra is 25 mg and it is prescribed to elderlies and people with other medical conditions yet the highest dose available for Revatio is just 20 mg. 20 mg is not enough to give you an erection even for an hour

With all the differences, it is clear that both medicines work in the same way but they were packed differently to address the different conditions that require sildenafil citrate for treatment. It is not advisable then to use Viagra in treating PAH and to use Revatio in treating ED.

Revatio for ED Reviews

Despite the fact that Revatio was not meant for treating impotence, some people still want to test it for some reasons. Here are some of their shared stories and how Revatio worked on them.

Revatio for ED Reviews

The overall rating of Revatio is 2.75 for effectiveness, 3 for ease of use and 2.75 for satisfaction. This is from people who used it for their ED treatment. We found two people who used it and the first user just gave it an overall rating of 2. He didn’t leave any comment. The second reviews gave it a rating of 4 saying that the facial flushing he experienced was mild and that it didn’t affect his performance.


Sildenafil 20 mg or Revatio is not an ED treatment. This medicine is designed and developed by Pfizer in order to treat pulmonary arterial hypertension. If used as an ED medicine, it won’t work effectively because of its weak dosage. Even if you will use it every day, it is not an assurance that it will work. This means that taking sildenafil 20 mg for ED is not highly recommended and that if you need an ED treatment, you better ask your doctor for an ED prescription.
