Beginner’s Guide to Revatio

Revatio Review

Pulmonary arterial hypertension (PAH) is one form of a broader health condition known as pulmonary hypertension. It’s high blood pressure that affects arteries in the lungs & the right side of the heart. Shortness of breath, dizziness, & chest pain are some of its symptoms. This condition can worsen over time if not treated. However, certain meds such as Revatio can aid in managing this disease & can enhance the quality of life. Besides, this drug is widely used off-label by men suffering from erectile dysfunction (ED) to help them get and maintain an erection hard enough for intercourse. It effectively helps manage the symptoms of this sexual problem, just like the famous ED med Viagra. Read this guide to know more about Revatio, including its main features & popularity, manufacturer, working aspect, dosage guideline, expected negative effects, interaction with alcohol & other meds, Revatio vs Viagra, & where to get it online safely and affordably.

Main Features and Popularity of Revatio

Revatio is a prescription medication used to treat pulmonary arterial hypertension. With PAH, the blood pressure in the lungs is too high. While there’s no cure for it, there are efficacious ways to lessen its symptoms and thus manage the disease. If the cause is identified & treated early, it may be possible to prevent permanent damage to the patient’s pulmonary arteries, which are the blood vessels that supply the lungs.

Revatio indeed helps treat PAH since it’s clinically proven to be very effective. The med ameliorates the capability to exercise & helps slow down worsening changes in the physical condition of the patient. In 2005, it was approved by the Food and Drug Administration (FDA) for the treatment of PAH [1].

The popularity of Revatio is due to its active ingredient – sildenafil citrate. It’s a phosphodiesterase type 5 (PDE5) inhibitor that relaxes blood vessels in the lungs. This enables blood to flow better & lowers the blood pressure in the lungs. This causes the heart to pump better, making the body get more oxygen, thus making the user breathe & exercise more easily. PDE5 inhibitors such as sildenafil also relax blood vessels in other parts of the body like the penile area to ameliorate blood flow, and that is why they are also used for the treatment of erectile dysfunction. ED is diagnosed if men have difficulty in achieving and maintaining an erection during intercourse.

Take note that Revatio isn’t FDA-approved to treat ED, although it contains sildenafil. However, many men use its generic versions for this health condition. As it’s a PDE5 inhibitor, just like Viagra, it’s indeed possible to have a prolonged penile erection after taking Revatio.

Who Manufactures This Drug?

Revatio is produced by Pfizer, an American multinational pharmaceutical & biotechnology corporation that’s famously known to produce Viagra®. Pfizer scientists originally developed sildenafil, the active ingredient of Revatio, for the treatment of pulmonary hypertension & angina pectoris. During the heart clinical trials, they discovered that the med was more effective at inducing erections than treating angina. After the discovery of the amazing sildenafil’s effects, Pfizer began to produce it under two different brand names for different health conditions: Viagra for ED & Revatio for PAH.

Pfizer Inc. is known for its great products like Advil, Xanax, & Zoloft. It specializes in the production of vaccines as well as cancer, heart, & diabetes treatments. It also makes meds for disorders of the endocrine and nervous systems. In 2020, Pfizer became the second-largest pharmaceutical company by revenue. In August 2021, the FDA approved Comirnaty, Pfizer’s COVID-19 vaccine.

Revatio: Where to Get Online?

Drugs Online

Not every online pharmacy genuinely sells what it says it offers. A majority of vendors sell counterfeit meds via the Internet. If seeking the best places to buy Revatio, it’s prime to be informed. We recommend the following e-drugstores that you can rely on for high-quality pills and great customer support.


ViaBestBuys (VBB) sells genuine meds sourced from approved manufacturers & offers them at the manufacturing cost. The vendor provides a complete refund or another free parcel reshipment in case of failed delivery due to country-specific customs laws. Parcel shipping is guaranteed to various parts of the globe except for very few countries listed on its website including Indonesia, Israel, & Mexico.

The e-pharmacy fulfills orders using 2 shipping options: Registered Airmail (standard) & Express Mail Service (EMS). They usually cost $29 & $39 respectively, but VBB offers a delightful bonus for its shoppers: free delivery on orders over $80 sent with Airmail & over $180 dispatched via EMS. Besides, order payments are made using cryptocurrency (a 25% discount), PayPal, or a credit card. Most of its shoppers opt for the bitcoin (BTC) payment option, as coupled with customized offers, coupons, & discounts, it allows them to save more money.


Like VBB, CialisBit (CB) sets itself up as a reliable place to buy Revatio pills as well as other ED drugs. It sources its meds from approved Indian pharmaceutical companies, so their quality can be guaranteed. It equally ships parcels worldwide except for very few destinations listed on its platform including Ireland, the United Arab Emirates, Pakistan, Israel, & Mexico.

The vendor offers 2 shipping options:

  • EMS with tracking, which takes 7–12 working days to deliver parcels to the USA, the UK, Europe, New Zealand, & Australia;
  • Registered Airmail, which takes 10–18 working days to the mentioned countries.

HighStreetPharma (HSP) is a legit e-pharmacy that sells a wide range of genuine health remedies at low prices. It isn’t as popular as CB & VBB, but it holds its own when it comes to shopper support as well as loyalty. Rest assured HSP keeps its prices the best on the market, & as usual, all shopper orders are covered with a satisfaction guarantee in case of any failed parcel delivery.

Although HSP ships Revatio & other offered health products globally, there are some countries (posted on its website) to which it doesn’t offer reshipments or refunds because of their strict customs & import laws. The vendor fulfills orders via 2 shipping options: EMS with tracking and Registered Airmail. The latter is free on orders worth $150+.

HighStreetPharma accepts credit cards, e-Check, PayPal, Amazon/Walmart gift cards, and Bitcoin. As a pleasant bonus to its clients, it offers a 10% returning customer discount.

What Is the Cost of Revatio?

Pills Cost

According to the price comparison website GoodRx.com, generic Revatio is covered by most Medicare & insurance plans, but some pharmacy coupons or cash prices may be lower. The lowest GoodRx price for generic Revatio 20 mg is $8.10 [2]. According to Drugs.com, the cost of branded Revatio 20 mg is $54.9 per tab, meaning that a supply of 90 pills will cost you around $4,941 [3].

As for the earlier mentioned e-pharmacies, they offer much lower prices for generic Revatio 100 mg. On CialisBit and ViaBestBuys, a supply of 30 tabs costs $69 ($2.29 per pill). HighStreetPharma offers the same number of tabs at $61.20 ($2.04 per tablet). It’s worth noting that the more tabs ordered, the lower the cost!

Revatio Pills vs Viagra

Both Revatio & Viagra contain the same active component – sildenafil citrate. Nonetheless, Viagra is FDA-approved to treat ED, whereas Revatio is certified by the FDA to treat PAH.

Here’s a comprehensive table showing similarities & differences between the two meds:

Brand Name Revatio Viagra
What med class does it belong to? PDE5 inhibitor PDE5 inhibitor
Who is the maker? Pfizer Pfizer
Is a generic version available? yes yes
What is the generic name? sildenafil sildenafil
What form(s) does the med come in? oral tab, injection, oral suspension oral tab
What is the advisable


20 mg 3 times daily for PAH, 100 mg taken once daily for ED 50 mg taken 30 minutes to an hour before intercourse
How long does it last? 4–5 hours 4–5 hours

Conclusively, Viagra & Revatio are very effective in treating their approved health conditions since they both contain a well-researched & well-tolerated active substance. Viagra is a more popular med than Revatio in the family of PDE5 inhibitors. Although both branded drugs are very expensive, the good news is that there are countless generic versions, which are very affordable – up to 90%+ cheaper than the brand name counterparts.

Working Aspect of Revatio

Icon Sex
Better Sex Life

The working aspect of Revatio is the same as that of Viagra because they contain the same active ingredient and belong to the same drug class. The med works by making the blood vessels in the lungs less rigid & widening them, which allows adequate blood to flow more smoothly without difficulty. Lessening high blood pressure in the lungs allows the heart & lungs to work better. Just like Viagra, it can also heighten blood flow to the penis, thus ameliorating erection. However, it requires sexual stimulation to start working.

As a PDE5 inhibitor, sildenafil citrate blocks or slows down the rate at which the enzyme PDE5 destroys cyclic guanosine monophosphate (cGMP). The latter is responsible for causing a hard erection through a series of complex processes that relax the arterial muscles in the penis, increasing blood flow.

Revatio Medication Dosage

Looking for the best ways on how to take Revatio? The recommended drug dose for treating PAH is 20 mg taken 3 times a day. The med should be administered every 4–6 hours apart [4]. Treatment with doses higher than 20 mg 3 times a day isn’t recommended. Generic versions of Revatio used off-label for ED have more dosing options. They are available in dose strengths of 100 mg, 80 mg, 60 mg, and 40 mg. Generic Revatio for ED is to be taken orally with a glass of water, 30–60 minutes before sex. On no occasion should more than one tablet be taken within 24 hours.

To treat high blood pressure in the lungs, the Revatio tab can be used with or without food as instructed by a physician. The dosage is based on your medical condition, response to treatment, as well as other meds you may be using. Always consult your physician before changing the dosage of Revatio or any other medicine.

Revatio with Alcohol & Other Medicines: Any Interactions

You may wonder, “Can my doctor prescribe me Revatio if I have a certain health condition?” Certainly, before using this med, it’s best to let your physician analyze your health for possible drug-disease interaction. Besides, Revatio may negatively interact with certain drugs. So, avoid taking this medication with the following types of meds [6]:

  • other PDE5 meds (tadalafil, avanafil, & vardenafil);
  • antifungals;
  • certain antibiotics;
  • alpha-blockers;
  • nitrates;
  • HIV protease inhibitors.

Tell your physician about all meds & supplements you’re using. Booze while on Revatio isn’t generally recommended. Taking the drug & drinking alcohol could heighten the risk of adverse effects.

What Are the Side Effects of Taking Revatio?

The most frequent side effects of Revatio are nosebleeds, flushing, headache, upset stomach, & trouble sleeping. Other negative reactions associated with the use of this drug may include memory problems, back pain, feeling faint, low blood pressure, muscle pain, shortness of breath, & visual disturbances. More serious side effects of this drug may also occur. They include loss of hearing, seizures, and irregular heartbeat, among other symptoms [5].

A severe allergic reaction to Revatio is rare. Nonetheless, get medical help swiftly if you notice any symptoms of a serious allergic reaction, including rash, itching/swelling (especially of the throat/face/tongue), trouble breathing, & severe dizziness. This isn’t a complete list of possible negative effects. If you notice other negative reactions not mentioned above, contact your physician for medical assistance.


🏆 The Popularity of Revatio: Myth or Reality?

Although the primary purpose of developing sildenafil was to get the most potent med for treating PAH, it became the pioneer med for ED. Its popularity has risen since millions of men across the globe suffering from ED began using it. However, unlike Viagra® that was specifically developed for ED, Revatio isn’t so popular for this condition. But still, some men use it off-label to manage symptoms of impotence and find it very effective. However, Revatio is quite popular for PAH, a condition that it was developed and approved for.

⏳ What Time of Action Have Revatio Tablets?

This med begins to function within 30–60 minutes after ingestion. It reaches peak levels in the blood about 1–2 hours after each dose, though it may be a couple of months before its full benefits kick in. When it’s used with a high-fat meal, the rate of absorption is lessened, with a mean delay in Tmax of about an hour.

💸 What Is the Price Range of Generic Revatio Drugs?

The price of Revatio varies based on the e-pharmacy visited. The average retail price of the branded drug is typically about $7,131, according to SingleCare.com. However, you may be able to lessen your out-of-pocket cost for this drug by using a SingleCare Revatio coupon at a local participating pharmacy such as Walmart, Kroger, CVS, or Walgreens.

Besides, you can still get generic Revatio at an extremely low price by using the recommended e-pharmacies such as CialisBit.com & ViaBestBuys.com. These vendors sell a pack of 30 pills for $69 ($2.29 per pill) and a pack of 100 pills for $99 ($0.99 per tab). You may also consider HighStreetPharma since it offers Revatio at $2.04 per tab for a supply of 30 pills or $1.60 per tab for a supply of 120 tabs.

🛒 What Are the Best Places to Order Revatio OTC?

Is Revatio available for sale online? Yes, but not every vendor selling it is legitimate. If you’re looking to buy quality & genuine Revatio pills over the counter (OTC), consider getting them from CialisBit, ViaBestBuys, or HighStreetPharma. However, each e-drugstore has various ways of shipping its products based on individual country-specific customs laws, so be sure to check each vendor’s shipping policy before placing an order.


That has been our in-depth review of Revatio, effective treatment for PAH. If used correctly, the med is safe and well-tolerated by most users. Because sildenafil, Revatio’s active ingredient, has proven effective at rectifying the symptoms of ED, this medication is also widely used off-label by many men to help them achieve a firm erection. Thus, it works the same way as Viagra, the most popular ED drug, as they contain the same active ingredient and belong to the same class of meds – PDE5 inhibitors. If you want to get Revatio over the counter, it can be sourced from a legit e-pharmacy like CialisBit, ViaBestBuys, or HighStreetPharma.
