If your cat in the US has been diagnosed with Feline Calicivirus (FCV) — or is showing signs such as chronic mouth ulcers, drooling, weight loss, or refusing to eat — one of the first things you'll search for is where to actually get treatment capsules. Not a general overview. Not another article about symptoms. The real product, available now.
This article gives you a direct answer to that question, along with everything a US-based cat owner needs to know before starting antiviral treatment.
The Direct Answer: CaliciX™ Ships to the United States
CaliciX™ by MolnuFIP is an oral antiviral capsule containing EIDD-1931 (15mg), specifically formulated for cats with FCV-related oral and systemic conditions. It ships directly to the United States from the MolnuFIP platform at $49.00 per bottle (60 capsules).
You do not need to source through third-party resellers, navigate grey market channels, or wait on local veterinary clinic stock. Orders are placed directly through the official MolnuFIP website and dispatched with full product documentation.
US cat owners can reach the MolnuFIP team before or after ordering via WhatsApp: +971 58 562 4801 or email: hello@molnufip.com — available for pre-purchase consultations, weight-based dosing guidance, and shipping questions.
Why FCV Antiviral Capsules Are Hard to Find in the US
This is a legitimate frustration, and if you've already searched PetSmart, Chewy, Amazon, or called around to local vets, you've likely come up empty — or found only supportive care products that don't address the virus itself.
Here's why: EIDD-1931-based antiviral treatment for cats is a new and emerging category in veterinary medicine. It is not yet stocked as an over-the-counter or standard prescription product at US veterinary clinics or major pet retail chains. Most American veterinarians currently manage FCV through antibiotics for secondary bacterial infections, corticosteroids to reduce inflammation, and dental procedures — none of which stops the virus from continuing to replicate in oral tissue.
This treatment gap is well-documented among cat owners dealing with Feline Chronic Gingivostomatitis (FCGS) and recurring FCV oral disease. Many have spent hundreds or thousands of dollars on repeated dental cleanings and antibiotic cycles without lasting improvement — because the viral root cause was never treated.
CaliciX™ fills that gap as a direct-order veterinary supplement available to US customers through the MolnuFIP platform.
What CaliciX™ Contains and How It Works
CaliciX™ contains EIDD-1931, an antiviral compound that works through a mechanism called lethal mutagenesis. Rather than blocking the virus directly, EIDD-1931 introduces replication errors into the viral copying process — errors that accumulate over time, progressively reducing the viral load and allowing your cat's immune system to gain the upper hand.
This mechanism is fundamentally different from anything in the standard FCV management toolkit:
Treatment | What it does | Addresses FCV virus? |
Antibiotics | Treats secondary bacterial infections | ❌ No |
Corticosteroids | Reduces inflammation temporarily | ❌ No |
Dental cleaning | Removes bacterial buildup | ❌ No |
CaliciX™ (EIDD-1931) | Disrupts viral replication | ✅ Yes |
CaliciX™ is indicated specifically for cats with:
Feline Chronic Gingivostomatitis (FCGS) — severe, recurring gum and mouth inflammation driven by an ongoing immune response to FCV persistence in oral tissue
Caudal stomatitis — deep inflammation at the back of the mouth, one of the most painful and treatment-resistant FCV manifestations
Ulcerative oral lesions — open sores on the tongue, gums, or palate that fail to heal because the viral trigger remains active
These are exactly the presentations that prompt US cat owners to contact MolnuFIP after cycling through conventional treatments without resolution.

How to Order CaliciX™ in the United States
Step 1 — Confirm your cat's FCV diagnosis A confirmed FCV diagnosis via PCR test is the recommended starting point. Most US veterinary clinics can perform or refer for FCV PCR testing. If your cat has already been diagnosed, or presents with classic chronic oral FCV signs, proceed to the next step.
Step 2 — Contact MolnuFIP for a free consultation Before placing your order, reach out to the MolnuFIP team at WhatsApp: +971 58 562 4801 or hello@molnufip.com. The team provides free educational consultations for US cat owners — covering the product, weight-based dosing protocol, what to expect during treatment, and how to share the treatment documentation with your vet. No charge, no obligation.
Step 3 — Place your order online Visit molnufip.com/product-page/stomaticure-feline-calicivirus-fcv to order. CaliciX™ ships to all US states — California, Texas, New York, Florida, Illinois, and all others. Shipping cost is calculated at checkout based on your delivery address.
Step 4 — Implement treatment under veterinary supervision CaliciX™ is a veterinary supplement used under vet guidance. MolnuFIP provides a complete FCV treatment protocol document that you can share with your veterinarian to align on monitoring, dosing schedule, and response assessment. Many US vets who were initially unfamiliar with EIDD-1931 have been able to supervise treatment successfully with MolnuFIP's support materials.
What US Cat Owners Ask Before Ordering
Is CaliciX™ FDA-approved?
CaliciX™ is a veterinary supplement, not a licensed veterinary pharmaceutical. In the US, veterinary supplements occupy a legal category that permits purchase and use without a prescription for your own pet. MolnuFIP recommends veterinary involvement throughout treatment — not as a legal requirement, but because monitored treatment produces better outcomes. If you have questions about the regulatory status, the MolnuFIP team can walk you through the details directly.
Can I get this through my vet or a US compounding pharmacy?
At this time, EIDD-1931 formulated specifically for cats at this concentration is not widely available through US veterinary distributors or compounding pharmacies. MolnuFIP's direct-order platform is the most reliable access point for US customers currently.
What does shipping to the US look like?
The MolnuFIP team can provide current estimated delivery windows for US addresses via WhatsApp before you order. Many US customers have received their orders within standard international shipping timeframes. Tracking is provided.
My vet hasn't heard of EIDD-1931 — is that normal?
Completely normal. EIDD-1931 for veterinary use is a newer category, and most US veterinary clinics haven't yet incorporated it into standard practice. MolnuFIP provides a veterinary resource pack — including mechanism of action, published research, and the treatment protocol — that you can bring to your vet appointment.

How many bottles will my cat need?
Treatment duration depends on your cat's weight, the severity of the condition, and response to treatment. The MolnuFIP team can provide a personalized dosing estimate based on your cat's weight during your free pre-order consultation.
Is $49 the full cost?
$49.00 USD is the product price per 60-capsule bottle. US shipping costs are added at checkout. The MolnuFIP team can provide a full cost estimate before you commit.
The Cost of Waiting: Why Timing Matters for US Cat Owners
One of the most consistent patterns among US cat owners who contact MolnuFIP is that they arrive after months — sometimes years — of cycling through antibiotics, dental procedures, and anti-inflammatory medications. By the time they reach out, their cat has lost significant weight, has visible gum damage, and is clearly suffering daily.
Chronic FCV-related oral disease is progressive. Every month of untreated viral activity means more immune-mediated tissue destruction, more scar tissue formation, and a harder road to recovery. US cat owners who start antiviral treatment earlier — before permanent oral damage accumulates — consistently see better outcomes than those who wait until the disease is advanced.
The total cost of three to five rounds of veterinary dental cleaning in the US, with anesthesia and follow-up antibiotics, typically exceeds the cost of a full CaliciX™ treatment course by a significant margin — with far less targeting of the actual problem.
