Both Revatio (sildenafil) and Viagra (sildenafil) treat pulmonary arterial hypertension (PAH) and erectile dysfunction (ED), but differ significantly in dosage and intended use. Revatio is a lower-dose sildenafil prescribed specifically for PAH, typically taken three times daily. Viagra, on the other hand, uses higher doses for treating ED, usually taken as needed.
Dosage and Administration
The key difference lies in dosage. Revatio uses much lower doses (20 mg) for PAH, while Viagra uses higher doses (25-100 mg) for ED. This results in different administration schedules. Patients taking Revatio for PAH follow a consistent daily regimen, whereas Viagra for ED is taken only when needed.
Specific Use Cases
While both drugs contain sildenafil, their FDA approvals and recommended uses are distinct. Revatio’s primary purpose is PAH management, offering a continuous treatment approach. Viagra targets ED, providing relief as needed. Using one drug for the other’s intended purpose requires medical supervision. Never self-medicate or adjust dosages without consulting a doctor.
