Dosing

Viagra: 50 mg as needed approximately one hour before sexual activity; 100 mg or 25 mg based on efficacy and tolerability; maximum once per day
Viagra: consider a 25 mg starting dose in severe renal impairment, hepatic impairment or with CYP3A4 inhibitors
Revatio adults: 20 mg three times a day; injection: 10 mg three times a day as an intravenous bolus

Revatio: combination with the most potent CYP3A4 inhibitors (e.g. ketoconazole, itraconazole, ritonavir); severe hepatic impairment

Important warnings
