CaliciX™ is a feline-specific antiviral treatment developed to support cats affected by Feline Calicivirus (FCV), a common viral infection responsible for painful oral disease in cats. Often referred to as calicivirus, feline calici, or virus calici, this infection is a leading cause of stomatitis, gingivitis, mouth ulcers, and chronic oral inflammation in cats. CaliciX™ is designed to target the virus directly, rather than only managing symptoms.
What Is Feline Calicivirus in Cats?
Feline Calicivirus (FCV) in cats is a highly contagious viral disease. Cats with Feline Calicivirus (FCV) may develop persistent inflammation in the mouth, making eating and grooming painful. Common search terms such as fcv cat, fcv in cats, and calici in cats all refer to this same condition.
Common Calicivirus Cat Symptoms
Cats suffering from Feline Calicivirus (FCV) may show:
- Severe gum inflammation
- Painful mouth ulcers on the tongue, gums, or cheeks
- Excessive drooling
- Bad breath
- Difficulty eating or swallowing
- Reduced appetite and weight loss
These calicivirus symptoms can worsen over time, especially in chronic or recurrent cases.
How CaliciX™ Helps Cats With Calicivirus
Each CaliciX™ capsule contains 15 mg of EIDD-1931, the active antiviral form, formulated specifically for cats. Unlike supportive care alone, CaliciX™ works by:
- Targeting Feline Calicivirus (FCV) replication
- Reducing viral activity at the source
- Supporting healing of oral tissues
This makes CaliciX™ a targeted option for calicivirus cats treatment, particularly when oral disease is persistent or recurrent.
Conditions Supported by CaliciX™
CaliciX™ may be used under veterinary guidance to support cats diagnosed with:
- Feline Chronic Gingivostomatitis (FCGS)
- Juvenile gingivitis
- Caudal stomatitis
- Viral mouth ulcers
- Glossitis associated with Feline Calicivirus (FCV)
Many cat parents report improvements in comfort, appetite, and overall quality of life when CaliciX™ is included in a veterinarian-guided treatment plan.
Why Choose CaliciX™ for FCV in Cats?
- Designed specifically for Feline Calicivirus (FCV)
- Contains EIDD-1931, not a human medicine
- Targets the viral cause, not just symptoms
- Supports long-term management of calici symptoms
If your cat suffers from calicivirus cat symptoms or recurring oral pain related to Feline Calicivirus (FCV), CaliciX™ offers a modern antiviral approach built specifically for feline needs.
Which Strength: CaliciX™ or CaliciX™ Max
- Mild cases (early ulcers, juvenile gingivitis, mild viral mouth irritation) and moderate cases (gingivostomatitis with eating discomfort, drooling, moderate ulceration): use CaliciX™
- Severe cases (Feline Chronic Gingivostomatitis (FCGS), caudal stomatitis, extensive ulceration, severe pain, anorexia): use CaliciX™ Max
Both strengths follow the same weight-based dosing. Your veterinarian chooses the strength.
Dosage Adjustment Guidance
Dosage may be adjusted by a licensed veterinarian based on the cat's clinical response. Signs that may indicate insufficient dosage include:
- Persistent drooling
- Pain or discomfort while chewing
- Slow healing of oral ulcers
- Unintended weight loss
Any dosage increase should remain within the recommended range and must be performed only under veterinary direction.
Veterinary Use Notice
Use under veterinary supervision. Dosage and treatment duration may vary based on the severity of Feline Calicivirus (FCV) in cats and clinical response.
CaliciX™ - 15mg Antiviral Therapy for Feline Calicivirus Stomatitis
Dosage Instructions
Administer one (1) capsule per 2.5 kg of body weight, given every 12 hours, preferably on an empty stomach. If vomiting occurs within 30 minutes, administer another capsule.
Dosing Examples
- Example 1: a 2.0 kg cat with Feline Calicivirus (FCV) associated gingivitis and mouth ulcers should receive one capsule every 12 hours.
- Example 2: a 4.6 kg adult cat with chronic Feline Calicivirus (FCV) oral disease should receive two capsules every 12 hours.
- Example 3: a 6.0 kg cat should receive three capsules every 12 hours.
Monitoring and Follow-Up
We recommend ongoing evaluation by your primary veterinarian, with a complete blood panel approximately every 30 days for cats on prolonged treatment. Regular monitoring allows your veterinarian to assess clinical response and determine whether continued treatment, dose adjustment, or discontinuation is appropriate.
Signs that may indicate insufficient dosage include persistent drooling, pain or discomfort while chewing, slow healing of oral ulcers, and unintended weight loss. A dosage increase may be warranted if symptoms persist after 30 days of treatment, and must be performed only under veterinary direction. Seek veterinary direction or contact us for recommendations.
