How Much Does a Full Course of NeoFipronis (Pronidesivir) Cost
NeoFipronis (Pronidesivir) is an oral FIP treatment designed for cats diagnosed with feline infectious peritonitis (FIP). Because FIP can cause loss of appetite, fever, lethargy, abdominal fluid, pleural effusion, lymph node enlargement, inflammatory granulomas, neurologic signs, and uveitis, many cat owners want to know one practical question first: how much does a full course cost?
The total price of NeoFipronis treatment depends on your cat’s weight, the form of FIP, the required dosage, and the seller’s packaging. For standard FIP cases, the usual dose is 15 mg per kg once daily. Neurologic FIP and ocular FIP often require a higher dose of 30 mg per kg, which can significantly increase the overall cost. Since treatment should continue for at least 12 weeks without missed doses, the full course price is always calculated over the entire treatment period, not by the day.
What Determines the Full Treatment Cost?
The biggest cost factor is body weight. A 3 kg cat needs much less active ingredient than a 6 kg cat, so the number of tablets or pieces used each day will be lower. A second factor is disease type. Wet FIP, dry FIP, neurologic FIP, and eye involvement may require different dosing strategies, and the higher the dose, the higher the final expense.
Packaging and market price also matter. Some owners buy by the box, while others buy by the bottle or blister pack. Shipping fees, import taxes, and local distributor pricing can also change the total amount. In addition, if your veterinarian recommends extending treatment beyond 12 weeks because of incomplete recovery or relapse risk, the full course cost will rise accordingly.
Estimated Cost of a 12-Week Course
Without a fixed global retail price, the best way to estimate cost is by formula. Calculate the daily dose based on body weight, multiply by 84 days, then convert that amount into the number of tablets or packages needed. For a standard FIP case, a small cat may need a much lower total amount than a larger cat. For neurologic or ocular FIP, the daily amount can double, so the final course cost may also approximately double.
As a general market estimate, a complete 12-week course can range from a few hundred dollars for smaller cats to well over a thousand dollars for heavier cats or higher-dose cases. If your cat has neurologic or ocular signs, the cost may be higher because the 30 mg/kg regimen uses more product every day. The exact price should always be confirmed from the official NeoFipronis source or a trusted veterinary supplier.
Why Owners Choose NeoFipronis for FIP
NeoFipronis (Pronidesivir) is valued because it is an oral, non-invasive option that is easy to administer at home. GS-441524, its active ingredient, has been widely discussed in FIP treatment research and clinical experience for its antiviral activity against the virus associated with FIP. Many owners prefer oral therapy because it is fast-absorbing, convenient, and generally well tolerated when used correctly.
Safety, Monitoring, and Veterinary Guidance
Although NeoFipronis is described as an over-the-counter cat medication, veterinary supervision is still strongly recommended. Cats should take it once daily, ideally on an empty stomach, and treatment should not be interrupted. During therapy, monitor appetite, temperature, energy level, and body weight, and arrange regular blood tests to check liver and kidney function. Cats with neurologic or eye involvement especially benefit from close follow-up.
NeoFipronis is for cats only and is not for human use. To protect product quality, purchase only from the official NeoFipronis website or another verified source recommended by your veterinarian.
