Revatio (sildenafil) is typically administered orally. Begin with a 20 mg dose once daily.
Adjusting Your Dose
Your doctor might adjust your dose based on your response and tolerance. Possible adjustments include increasing to a maximum of 40mg once daily or reducing the dosage as needed. Always follow your doctor’s instructions.
Important Considerations
Take Revatio with or without food. However, consistency is key; choose one method and stick with it for predictable results. Avoid grapefruit and grapefruit juice as they can affect how your body processes Revatio.
Missed Dose
If you miss a dose, take it as soon as you remember, unless it’s almost time for your next dose. Never double up on doses.
