HerpX™ delivers famciclovir, the oral antiviral most established for Feline Herpesvirus (FHV-1), in a fixed-strength feline tablet designed for consistent, weight-based dosing. Rather than fractioning human cold-sore tablets, HerpX™ provides a precise, repeatable approach to antiviral support during Feline Herpesvirus (FHV-1) flares.
Purpose-Built for Feline Herpesvirus (FHV-1)
Each HerpX™ tablet contains 180 mg of famciclovir, sized for practical weight-based dosing in cats. Famciclovir is a prodrug of penciclovir, a nucleoside analogue with demonstrated activity against Feline Herpesvirus (FHV-1).
Backed by Published Feline Research
Famciclovir for cats is supported by a body of published feline pharmacokinetic and clinical work, including dose-optimisation modelling and a 59-case clinical series covering ocular, respiratory, and dermatologic disease attributed to Feline Herpesvirus (FHV-1). This evidence base informs the widely cited dosing approach of approximately 90 mg/kg every 12 hours used under veterinary direction.
Chosen for Cats, Not Adapted From Human Antivirals
Famciclovir is regarded as systemically safe in cats when dosed appropriately. This is an important distinction from acyclovir and valacyclovir, human antivirals associated with toxicity in cats. HerpX™ is intended specifically for feline use under veterinary guidance.
Support Across the Main Forms of Feline Herpesvirus (FHV-1)
HerpX™ is intended to support cats through:
- Ocular flares (conjunctivitis and corneal disease)
- Upper respiratory flares (sneezing, nasal discharge, congestion)
- Recurrent flares triggered by stress
Consistent Dosing, Clear Guidance
- Fixed 180 mg feline tablet for repeatable weight-based dosing
- Designed around the published feline dosing literature
- Used under veterinary supervision, with no need to modify human medication
HerpX™ provides a clearer, more controlled path to managing Feline Herpesvirus (FHV-1) flares and protecting your cat's comfort and eyes.
