CaliciX™ Max – Antiviral Therapy for Feline Calicivirus
Targeted Treatment for Chronic Oral Disease in Cats
What Is CaliciX™ Max?
CaliciX™ Max is a feline-specific antiviral capsule containing 30mg of EIDD-1931 (NHC), the active antiviral metabolite designed to suppress feline calicivirus (FCV) replication and reduce viral load in cats suffering from chronic oral disease.
Unlike supportive care that only manages symptoms, CaliciX™ Max targets the virus at its source—helping cats with persistent stomatitis, gingivitis, and oral ulcers caused by FCV.
⚠️ Is Your Cat Suffering From These Symptoms?
Feline calicivirus (FCV) is a highly contagious viral infection that causes painful, chronic inflammation in the mouth. Infected cats may show:
❌ Severe gum inflammation (red, swollen gums)
❌ Painful mouth ulcers on tongue, gums, or cheeks
❌ Excessive drooling (often blood-tinged)
❌ Bad breath (halitosis)
❌ Difficulty eating or refusing food entirely
❌ Weight loss due to pain while eating
❌ Pawing at the mouth or avoiding grooming
❌ Lethargy and behavioral changes from chronic pain
Without antiviral intervention, these symptoms often worsen over time—leading to severe weight loss, malnutrition, and drastically reduced quality of life.
Conditions Treated with CaliciX™ Max
CaliciX™ Max is formulated to support cats diagnosed with FCV-related oral diseases, including:
✅ Feline Chronic Gingivostomatitis (FCGS) – severe, persistent inflammation of gums and oral tissues
✅ Caudal Stomatitis – inflammation at the back of the mouth and throat
✅ Viral Mouth Ulcers – painful lesions on tongue, palate, or gums
✅ Juvenile Gingivitis – early-onset gum disease in young cats
✅ Glossitis – tongue inflammation associated with calicivirus
✅ Recurrent FCV flare-ups in previously treated cats
How CaliciX™ Max Works
EIDD-1931: The Active Antiviral
CaliciX™ Max contains EIDD-1931 (β-D-N4-hydroxycytidine), the active metabolite that directly inhibits viral replication.
CaliciX™ Max uses the direct active form (EIDD-1931) for:
- Faster action – no waiting for metabolic conversion
- More consistent results – doesn't depend on individual liver metabolism
- Higher bioavailability – 100% active compound, not prodrug
Mechanism of Action:
EIDD-1931 works through lethal mutagenesis:
- Virus mistakes EIDD-1931 for a natural building block (cytidine)
- Incorporates it into viral RNA during replication
- This causes catastrophic errors in the virus's genetic code
- Viral replication stops → viral load drops dramatically
Result: Reduced inflammation, faster healing of ulcers, less pain, improved appetite.
Why CaliciX™ Max Is Different
1. Targets the Virus, Not Just Symptoms
Traditional treatments for FCV-related stomatitis include:
- Antibiotics (treat secondary infections, but don't touch the virus)
- Steroids (reduce inflammation temporarily, suppress immune system)
- NSAIDs (manage pain, don't address viral cause)
- Tooth extraction (removes infected teeth, but virus remains in tissues)
By targeting the virus at its source, CaliciX™ Max helps cats achieve:
- Pain relief that goes beyond temporary symptom management
- Healing of damaged oral tissues
- Improved appetite and weight gain
- Better quality of life for both cat and owner
