Revatio, containing sildenafil, is typically prescribed at 20mg three times daily for pulmonary arterial hypertension (PAH). Viagra, also containing sildenafil, is usually administered as a single dose of 50mg, taken as needed, approximately one hour before sexual activity. This reflects their distinct applications: Revatio for ongoing treatment of PAH, and Viagra for treating erectile dysfunction (ED) on an as-needed basis.
Dosage adjustments for both medications depend on individual response and potential side effects. Your doctor will carefully monitor your progress and adjust your dose accordingly. For example, Viagra dosages may range from 25mg to 100mg depending on efficacy and tolerability. Revatio dosages, while typically starting at 20mg three times daily, might be increased or decreased based on individual patient needs and response to treatment.
Both medications are taken orally. However, remember that the timing of administration differs significantly: Revatio is taken consistently throughout the day, whereas Viagra is taken only when needed for ED. Always follow your doctor’s specific instructions regarding dosage and timing.
While both drugs contain sildenafil, their distinct dosage regimens reflect their different therapeutic purposes. Consult your physician for personalized advice on dosage and administration specific to your health condition and needs.
