Overview of Revatio

Revatio, also known by its generic name sildenafil, is a prescription medication primarily used for the treatment of pulmonary arterial hypertension (PAH). PAH is a condition characterized by high blood pressure in the arteries of the lungs, which can lead to shortness of breath, fatigue, and ultimately heart failure if left untreated.

How Revatio Works

Revatio belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors. It works by relaxing the blood vessels in the lungs, allowing blood to flow more easily. This helps to reduce the strain on the heart and improve exercise capacity in patients with PAH.

Usage of Revatio

Revatio is typically taken orally in the form of tablets, and the recommended dose varies depending on the individual’s condition and response to the medication. It is important to follow the dosage instructions provided by a healthcare professional to ensure optimal treatment outcomes.

Potential Side Effects

Like any medication, Revatio may cause side effects in some individuals. Common side effects of Revatio include headache, flushing, and indigestion. More serious side effects such as sudden vision loss or hearing loss are rare but may occur. It is important to discuss any concerns or side effects with a healthcare provider.

Important Considerations

Before taking Revatio, it is crucial to inform a healthcare provider about any existing medical conditions, medications, or allergies. Revatio should not be used in combination with certain medications, particularly nitrates, as this can lead to a dangerous drop in blood pressure.


In conclusion, Revatio is a valuable medication for the treatment of pulmonary arterial hypertension. By understanding how Revatio works, its potential side effects, and important considerations, individuals can make informed decisions about its use in managing their condition. Always consult with a healthcare provider before starting or changing any medication regimen.

Revatio Dosage and Administration

Dosage Information

Revatio is available in tablet form for oral administration. The recommended dosage of Revatio for adults with PAH is 20 mg three times a day, approximately 4 to 6 hours apart. The maximum recommended dosage is 20 mg three times a day. It is important to follow your healthcare provider’s instructions regarding the dosage and duration of treatment with Revatio.

Administration Instructions

Revatio tablets should be taken orally with or without food. It is recommended to take each dose at the same times every day to maintain a consistent level of the medication in the body. Do not crush, chew, or split the tablets before swallowing. Always swallow the tablets whole with a glass of water.

If you miss a dose of Revatio, take it as soon as you remember. However, if it is almost time for your next dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one.

Special Populations

For patients with hepatic impairment, the initial dose of Revatio should be 20 mg once daily. It is essential to consult a healthcare provider for appropriate dosage adjustments in patients with hepatic impairment. Revatio is not recommended for use in patients with severe hepatic impairment.

For patients with renal impairment, no dosage adjustment is necessary as sildenafil, the active ingredient in Revatio, is not eliminated extensively through the kidneys.

Drug Interactions

Revatio may interact with other medications, such as nitrates, riociguat, and certain antifungal medications. Inform your healthcare provider about all the medications you are currently taking, including prescription and over-the-counter drugs, herbal supplements, and vitamins, to avoid potential drug interactions.
