Revatio is the brand name for sildenafil citrate, a powerful PDE5 inhibitor that is commonly used to treat erectile dysfunction (ED) in men. In addition, sildenafil is also one of the best ways to manage pulmonary hypertension, a rather rare condition that causes elevated blood pressure in the arteries leading to the lungs. Following the discovery of this beneficial effect, sildenafil was branded as Revatio and is now being prescribed to patients all over the world to minimize the symptoms of pulmonary hypertension and prevent it from progressing.

In this page we are going to take a closer look at both Revatio and its generic analog, sildenafil. Keep reading to find out about Revatio side effects, warnings, and safe use guidelines.

How should Revatio be taken?

Initially, sildenafil was only meant to be taken by men, so there are relatively few studies that focus on the pharmaceutical’s effect on women. At the same time, pulmonary hypertension is more widespread among female patients, so more research is needed to learn about the full extent of sildenafil effects of the female body. For now, healthcare experts recommend avoiding Revatio if you are pregnant, breastfeeding, or expecting to become pregnant in the next several months. Sometimes, the benefits of using Revatio in pregnant or breastfeeding women outweigh the potential risks, but it is only up to your doctor to decide whether that is true in your particular case.

Patients of both genders need to be particularly careful when using Revatio if they also suffer from cardiovascular problems, hypotension, as well as kidney and/or liver problems. In addition, Revatio may also be dangerous for people who have rare conditions such as retinitis pigmentosa, Peyronie’s disease, or a history priapism (painful prolonged erections that last for 4 hours or longer).

What are your options when buying Revatio?

If you want to go for the branded version of the drug, you can choose to get it from either an online or brick and mortar pharmacy. You may be able to buy Revatio online at a slightly lower price, but the total savings are likely to be insignificant. If you want to save a considerable amount of money, you are better off choosing sildenafil, the generic pharmaceutical that “powers” Revatio.

Generic medications are widely available in online pharmacies and are also making their way to the brick and mortar drug stores. However, it is a good idea to order generic Revatio online because virtual pharmacies often offer coupons, flexible discounts, and even bonus pills to both new and returning customers. If you are going to be using Revatio on a long-term basis, you’ll definitely save a considerable amount of money by becoming a regular customer at an online drug store.

However, bear in mind that you can’t just choose a random website that offers one of the lowest prices and order your Revatio supplies from it. You have to do your research first to find out what online pharmacies are reliable and are not going to sell you a counterfeit product. As a rule of thumb, it is always a good idea to avoid websites that look sketchy and don’t seem like they took a lot of effort to create. Ordering from such a website will not only lead to you getting a low-quality product, but may also expose your personal data and credit card details to cybercriminals. To stay on the safe side, be sure to order sildenafil from an online drug store that looks trustworthy, has been around for a while, and has mostly positive reviews. The price offer you’ll get is unlikely to be the best one out there, but your health and financial security are definitely worth paying a little more.

What should you take into account before using?

Before you start taking Revatio, be sure to have read and understood the instructions on your prescription label. If you have any questions or concerns, do not hesitate to clarify them with your healthcare provider or pharmacist before you actually start using the drug.

Revatio has a direct impact on your cardiovascular system, so it is important that you minimize the use of any other substances that affect your heart and blood flow for the duration of your Revatio treatment. These substances include not only other medications you may be taking, but also recreational drugs and alcohol.

It is recommended that you don’t take Revatio on an empty stomach because this increases your chances of experiencing gastrointestinal discomfort as an adverse reaction to the medication. Take Revatio with a glass of water and try to leave even periods of time between your regular doses.
Store Revatio in a safe place that is out of reach for children and pets. Make sure that your chosen place is not exposed to excessive light or moisture. Do not share Revatio with other people even if their symptoms are very similar to yours. If you still have some pills left after your treatment course is over, ask your local pharmacist for instructions on how to dispose of them properly.

Dosage Guidelines

The information provided in this article is only intended for reference purposes and is not meant to substitute an appointment with your healthcare provider. Only a qualified healthcare professional can determine whether it is safe for you to start using Revatio and decide what starting dosage is appropriate for you.

The most common approach to initial dosages for most drugs is to start with the smallest dose possible and slowly increase it if it turns out to be insufficient. When using Revatio for pulmonary hypertension, you can start with as little as 5mg of sildenafil on a daily basis. If this amount of the drug is effective, you can continue taking it until instructed to do otherwise by your doctor.

Some patients need a higher daily dose of Revatio, so their dosage could go up to 20mg. Taking more than 20mg of Revatio on a daily basis is not recommended as it increases your risk of developing serious side effects. However, in some cases the benefits of an increased daily dosage could outweigh the potential risks, so your healthcare provider may discuss this possibility with you if your pulmonary hypertension symptoms are becoming more prominent and difficult to manage.

In case of accidental overdose, be sure to seek urgent medical help as depending on the ingested dose, the consequences could be very severe and even lethal. If the overdose did not exceed the maximum allowed daily dosage of 100mg, you may not experience any serious symptoms. In case of a mild overdose, no medical attention may be required, but it is still crucial that you stay alert for any unusual symptoms and refrain from operating heavy machinery for at least 24 hours after the overdose.

What should you watch out for when using Revatio?

Revatio is a fairly safe medication, as it doesn’t have many serious side effects. Most users don’t experience any adverse reactions to the medication at all, but in some cases, mild side effects occur as the body’s natural response to a new pharmaceutical. These side effects are normally harmless and should go away of their own accord within about 10 days after you start taking Revatio. Mild Revatio side effects include but are not limited to dizziness, lightheadedness, mild to moderate headaches, facial flushing, upset stomach, and trouble falling asleep.

Serious Revatio side effects are very rare and require immediate medical attention to minimize the risk of the user’s health suffering permanent damage. Since Revatio interferes with the blood flow, it may cause temporary vision and/or hearing loss in some patients. This side effect is associated with the temporary lack of blood at the optical and/or hearing nerves and should go away after some time. Do not continue using Revatio if it has a negative impact on your vision or hearing, and be sure to report having experienced this side effect to your healthcare provider. Permanent vision and/or hearing damage from using Revatio is extremely rare and very unlikely to happen in people who don’t have any history of hearing/vision disorders.

Be sure to seek professional medical help immediately if you feel extremely lightheaded, have trouble breathing, or faint after taking Revatio. These symptoms may indicate a dangerous interaction with another medication or be a sign of a serious allergic reaction to Revatio. Other symptoms of an allergic reaction include dizziness, rash, itching and/or swollen body parts, as well as trouble breathing. Do not hesitate to seek professional medical attention if you think that you might be having a serious allergic reaction to the drug, as it could be dangerous for your overall health and well-being.
