Recommended Dosage in Adults

​Oral Dosage

​The recommended dosage of REVATIO is 20 mg three times a day. Dose may be titrated to a maximum of 80 mg three times a day, if required, based on symptoms and tolerability [see Clinical Studies (14)].

​Although dose-response improvement in exercise ability was not observed in short-term studies in adults with PAH, the delay in clinical worsening with long-term use of sildenafil in Study A1481324 supports dosing up to a maximum of 80 mg three times a day [see Clinical Studies (14)].

Intravenous Dosage

​The recommended dose is 10 mg administered as an intravenous bolus injection three times a day. The dose of REVATIO injection does not need to be adjusted for body weight.

​A 10-mg dose of REVATIO injection is predicted to provide pharmacological effect of sildenafil and its N-desmethyl metabolite equivalent to that of a 20-mg oral dose.

Recommended Dosage in Pediatric Patients

​Oral Dosage

​The recommended dosage in patients ≤20 kg is 10 mg three times a day.

​For pediatric patients 20 kg to 45 kg, the recommended dosage is 20 mg three times a day.

​For pediatric patients 45 kg and greater, the recommended dosage is 20 mg three times a day. A maximum dose in pediatric patients has not been identified.
