- Consistency: Try to take Revatio at the same times each day to maintain a consistent level of the medication in your bloodstream.
- Missed Dose: If you miss a dose, take it as soon as you remember. However, if it’s almost time for your next scheduled dose, skip the missed dose and continue with your regular dosing schedule.
- Overdose: Do not take more than the prescribed dose, as this can increase the risk of side effects. If you suspect an overdose, seek medical attention immediately.
