Sildenafil 20mg Side Effects: Be Careful With the Side Effects of Sildenafil 20mg

Sildenafil is available in various quantities but our focus in this instance is the Sildenafil 20mg pill. Sildenafil 20mg is a generic drug better known as Revatio. Revatio is a drug used to treat pulmonary arterial hypertension primarily. I insist that it is primarily used to treat pulmonary arterial hypertension because it can also be used to treat erectile dysfunction.

The side effects of Revatio include flushing of the face or neck (characterized by a redness or warmth), memory problems, a stuffy nose, back pain, headache, dizziness, low blood pressure, and shortness of breath. This is not a conclusive list of possible side effects associated with the use of Revatio. We are all differently and inherently, we respond differently to different conditions. Although these are the common side effects, if you notice different complications that coincide with you taking a dose of Revatio, consult your doctor so that you can clear things up and avoid tragedy.

Besides these common side effects, some people are just allergic to sildenafil. It is not odd to find a patient who reacts in a very drastic way to doses of Revatio. Some common allergic reactions you are likely to see if you are one of these people include swelling of the tongue, lips, face, or throat and difficulty breathing. Difficulty in breathing is life-threatening and you should immediately get help. Swelling of the various body parts is a very uncomfortable feeling. In case you spot any of these signs, go to the hospital to have them administer an antihistamine.

If you use Revatio, you should also be aware of the more serious side effects that are nothing short of life-threatening and that you should report immediately. The serious side effects include a change in your hearing such as hearing loss or a ring in the ears, sudden visual impairment, an irregular heartbeat, a heavy feeling or intense pain in the chest, a shortness of breath, visual complications, and a prolonged erection known as priapism. Priapism is particularly problematic as it can lead to more complications with your penis and having erections down the road.

Does Revatio Work Like Viagra?

Clinically speaking, Revatio and Viagra are the same things. They both contain Sildenafil Citrate. Revatio can be used as an ED medication while Viagra can be used to treat PAH if the dose is adjusted. They both work as PDE-5 inhibitors and they relax the blood vessels in the same manner.

Sildenafil 20mg vs Viagra

Sildenafil 20mg is known as Revatio, as has been established. Since it contains Sildenafil Citrate, as does Viagra, how do they compare? The first thing is to point out the similarity. Both contain Sildenafil Citrate as the active ingredient. Sildenafil Citrate is used to treat ED or basically any illness that requires the blood to flow with ease. However, this does not give the license to take it however you feel like. Consult your doctor first, always.

Viagra comes in an assortment of doses. It contains 25mg, 50mg, and 100mg and is mainly used to treat erectile dysfunction. In Revatio, the dose comes in 20mg only and is mainly used to treat a condition known as pulmonary hypertension. While both are versions of Sildenafil, Revatio is available for the sole purpose of treating pulmonary hypertension, it can be used as a cure for Erectile Dysfunction. Such a versatile usage of the drug is known as off-label use. In essence, even though we can access to both Viagra and Revatio, only the 20mg tablet is a used by doctors as an off-label cure for ED.

Revatio comes in 20mg as approved by the FDA to treat Pulmonary Arterial Hypertension (PAH). Technically, it contains 20mg of the very same active ingredient in 50mg or 100mg Viagra. Consequently, Revatio is cheaper than Viagra. It is common to find people using Revatio for ED if they cannot afford Viagra. The initial dose of Viagra is 50mg but with Revatio, it allows a smaller starting dose to be used and a better way of determining the best dosage.

Revatio is more practical for you if you just need a nudge in the right direction when you have mild ED. This could be in situations where you (the man) has some jitters and anxiety in a new relationship or going through a rough patch leading to stress. It allows you to focus on pleasure rather than the process.

How to Take Sildenafil 20mg

Revatio is taken either during meal times or in between meals. The space between the intakes should be around 4 to 6 hours since Sildenafil 20mg when taken for PAH is a prescription drug that is taken daily. Do not take more than 20mg per dose. Always seek the advice of your doctor before you start taking Revatio. In any case, you need a prescription for it.

If you can’t take Revatio orally, you can use an injection to administer it. When you administer Revatio intravenously, you should take a 10mg dose or 12.5mL. 10mg administered intravenously is considered equivalent to 20mg taken orally.


Sildenafil 20mg is known as Revatio. It is used to treat PAH but it can also be used to treat ED. As it is a sildenafil drug, it causes some side effects in patients. Some side effects are mild while others are serious. When you spot the serious side effects, get emergency medical attention to avert disaster. Always use Sildenafil 20mg under the watchful eye of a doctor.

Both Viagra and Revatio are sildenafil products. They can be used interchangeably.
