One of the best ways to ensure that you do not miss out on a dose is to maintain a fixed regime for consuming Famvir each day.
Drug Class and Mechanism
Famvir falls under antivirals and it works by blocking reproduction of the virus.
You must maintain a schedule for taking the medicine at the same time each day so that you do not miss out on any doses. But, in the advent of a missed dose, take it as soon as you remember so that you can compensate for the loss of the dose.
But, then you may need to adjust your remaining doses accordingly. And if it is almost time for the next dose, then please skip the missed dose and continue with the normal schedule.
Never try to compensate for the missed dose by taking a double dose together. It may cause adverse effects.
