Chickenpox Not Controlled After Oral Antiviral Therapy: When Fever or New Vesicles Persist Beyond 6 Days

This protocol covers chickenpox that has not responded adequately to an initial oral antiviral course — specifically when fever or new vesicle formation continues beyond the expected window of response after treatment onset.

Previous Treatment & Failure Condition

A 7-day course of oral antiviral therapy — Valaciclovir, Famciclovir, or Aciclovir — was given alongside symptomatic relief measures. Escalation is indicated when fever has not settled or new vesicle formation has not ceased, with either finding persisting beyond 6 days from disease onset.

Next-Line Approach

This protocol involves hospital admission to an isolation bed with intensified antiviral treatment and regular monitoring. The complete regimen — including therapy duration, transition criteria to oral treatment, and the specific agents used — is set out in the full structured protocol.

Treatment Goal

Settling of temperature.

Aciclovir at a dose of 10 mg/kg intravenously every 8 h should be used for those who have or are at risk of severe disease.
Two weeks therapy may be appropriate in severe disease or in the immunocompromised, for whom intravenous therapy is usually recommended, although with rapid improvement an early switch to oral therapy may be considered.
Switch to oral therapy as soon as possible
