Switching to or from Antiviral Medications
Switching medications is more nuanced than simply stopping one and starting another.

This page outlines the practical considerations at 200mg, 400mg, 800mg, 30mg, 45mg.
Switching within the same class
Switching from another Antiviral Medications agent to Antiviral Medications, or vice versa, is usually direct: the prescriber establishes the equivalent dose of Acyclovir, Oseltamivir, Valacyclovir and the schedule, and the change happens on a defined day.

Switching across classes
Switching to Antiviral Medications from a different therapeutic class is more involved. Some switches require a washout period (especially when crossing receptor antagonists/agonists or shared metabolic pathways), others use cross-titration where both medications overlap briefly. The prescriber chooses the protocol based on the medications involved, the indication and individual factors at 200mg, 400mg, 800mg, 30mg, 45mg.
Frequently asked questions
Can I switch directly from another medication to Antiviral Medications? ▾
Sometimes yes — within the same class, direct switches are common. Across classes, a structured protocol (washout or cross-titration) is usually safer. The prescriber confirms whether direct switch to Antiviral Medications at 200mg, 400mg, 800mg, 30mg, 45mg is appropriate.
What should I do if the switch isn't working? ▾
Switching results vary; the underlying condition may need a few weeks to restabilise on the new medication. If symptoms worsen significantly or new side effects appear, contact the prescriber for review rather than waiting indefinitely or self-switching back to the original medication.
