How Much Does FIP Treatment Cost in the Philippines?

The total cost of Feline Infectious Peritonitis (FIP) treatment in the Philippines depends on three main things: your cat's weight, the form of FIP your cat has, and which treatment route you and your veterinarian choose over the standard 84-day (12-week) protocol. Because dosing is based on weight and the treatment runs daily for 84 days, heavier cats and longer or more advanced cases generally need more medication. For an exact quote for your cat, the most reliable step is a free consultation with the BasmiFIP team alongside your own veterinarian.

How much does FIP treatment cost in the Philippines?

FIP treatment cost in the Philippines is not a single fixed number, because the amount of antiviral your cat needs is calculated from body weight and continues daily for the full 84-day protocol. This means a small kitten and a large adult cat will not pay the same total, even for the same form of FIP.

We understand that price is often the first question a worried Pawrent asks. You are not alone in that. Many families in the Philippines have walked this exact path since 2019, and there is a clear way to plan your budget once you know your cat's weight and FIP form.

Rather than guess at a figure, the honest approach is to look at the factors that drive the cost, then get a personalized quote. You can read more about the local treatment landscape in this guide to FIP treatment in the Philippines.

What decides the total cost of FIP treatment?

The total cost of FIP treatment is decided by four factors: your cat's weight, the form of FIP, the treatment route (injectable or oral), and the full length of the protocol. Each factor changes how much medication your cat needs from start to finish.

Here are the main cost drivers:

• Weight. Antiviral dosing is per kilogram, so heavier cats need larger daily amounts.

• FIP form. Wet, dry, ocular, and neurological FIP are dosed differently, and the neurological and ocular forms need higher dosing.

• Treatment route. Daily injections and oral capsules have different pricing structures.

• Protocol length. The standard course is 84 days, and some cats need adjustments guided by their veterinarian.

Because every cat is different, a Filipino family with a 3 kg cat with wet FIP will plan a very different budget from a family with a 6 kg cat with neurological FIP.

How does your cat's weight affect FIP treatment cost?

Your cat's weight directly affects FIP treatment cost because both the GS-441524 injectable and the oral capsules are dosed by body weight. A heavier cat needs a larger daily dose, which means more medication across the 84-day protocol.

For the GS-441524 injectable (BasmiFIP Antiviral, 40 mg/ml, 99.4% purity), the daily dose depends on the FIP form:

• Wet (effusive) FIP: 6 mg/kg

• Dry (non-effusive) FIP: 8 mg/kg

• Ocular FIP: 10 mg/kg

• Neurological FIP: 10 mg/kg

So a cat that weighs twice as much needs roughly twice the daily medication. This is the single biggest reason two cats with the same diagnosis can have very different total costs.

Weighing your cat accurately at the start, and re-checking during treatment, helps you and your veterinarian plan the budget realistically.

Does the form of FIP change the cost?

Yes. The form of FIP changes the cost because FIP has four forms, and the more advanced forms require higher dosing. FIP appears as wet (effusive), dry (non-effusive), ocular, and neurological, and the neurological and ocular forms are dosed at 10 mg/kg, higher than the 6 mg/kg used for wet FIP.

Ocular and neurological FIP are two separate forms, not one. Both need higher GS-441524 dosing because the antiviral has to reach the eyes or the nervous system, and higher dosing means more medication per day.

For ocular or neurological FIP, or for any cat that is not eating or passing stool normally, treatment starts with GS-441524 injections. The EIDD-1931 oral capsules are not recommended for ocular or neurological FIP.

Wet and dry FIP without ocular or neurological signs give you more flexibility, which can help with budgeting. Understanding your cat's exact form is why the right diagnosis comes first, and what the blood test results mean during treatment is worth reading early.

Injections or capsules: which route affects your budget?

Both injections and oral capsules are valid routes, and the choice affects your daily routine as much as your budget. Injectable GS-441524 is the primary FIP antiviral and is used from day one for ocular, neurological, or unstable cats, while oral options can suit stable wet or dry cases.

BasmiFIP offers three main FIP treatment products:

Product	What it contains	Typical use
GS-441524 injectable	40 mg/ml, 99.4% purity, 8 ml vial	Primary antiviral for all FIP forms, daily for 84 days
EIDD-1931 oral capsules	15 mg per capsule, 60 per bottle	Wet or dry FIP only, not ocular or neurological
Dual Antiviral oral capsules	GS-441524 + EIDD-1931, 1 capsule daily	After about 30 days of injections or once the cat is stable

The oral capsule dosing follows simple weight bands. For EIDD-1931 capsules, cats under 2.5 kg take 1 capsule every 12 hours, cats 2.5 to 5 kg take 2, and cats over 5 kg take 3.

For the Dual Antiviral capsule (one capsule per day), the strength scales with weight: under 2.5 kg gives GS 25 mg + EIDD 5 mg, 2.5 to 5 kg gives GS 35 mg + EIDD 8 mg, and over 5 kg gives GS 50 mg + EIDD 10 mg. Your veterinarian will confirm the right route for your cat's form and stability.

Important safety note: EIDD-1931 is potentially teratogenic, so no EIDD-1931 product should be used for pregnant, nursing, or breeding cats.

How long is the FIP treatment protocol, and why does that matter for cost?

The standard FIP treatment protocol is 84 days, which is 12 weeks of daily antiviral treatment. Because the medication is given every single day for that full period, the length of the protocol is a major part of the total cost.

Some cats follow a stepped plan. For wet or dry FIP without ocular or neurological signs, some families may start EIDD-1931 for 30 days, extend if symptoms persist, and if symptoms continue past 60 days, switch to GS-441524 at 10 mg/kg. For ocular or neurological FIP, or cats not eating or pooling normally, treatment starts with GS-441524 injections for 30 days, then may switch to the GS-441524 Dual Antiviral capsule.

Consistency across all 84 days matters for outcomes, not just cost. Filipino families sacrifice a lot to afford FIP treatment, so a formula built to last the full 84 days is exactly what your cat's recovery journey needs.

What results can Filipino Pawrents expect for the money?

The track record is what gives many Filipino families hope. GS-441524 has a 92% success rate in the UC Davis clinical trial, and more than 100,000 cats have been treated since 2019.

Dual antiviral therapy has its own strong data. In the Li and Cheah 2025 field study, 78.3% of cats achieved remission with combined GS-441524 and EIDD-1931 therapy, including some previously relapsed cases. You can read the study results on dual antiviral recovery for the details.

These two numbers describe two different approaches, so we never mix them. What they share is a clear message: your cat's odds are better than they have ever been.

Are there costs beyond the antiviral medication?

Yes. Beyond the antiviral itself, most families budget for diagnosis, veterinary check-ups, and supportive care that helps your cat stay comfortable through the 84 days. Planning for these avoids surprises later.

Common additional costs include:

1. Initial diagnosis and blood work to confirm the FIP form.

2. Follow-up veterinary visits and repeat blood tests during treatment.

3. Supportive nutraceuticals for organ support, when your veterinarian advises them.

4. Good nutrition and any treatment for secondary issues.

Supportive products such as LiverRx and KidneyRx are adjunct organ support only. LiverRx for cats and small dogs contains SAMe 90 mg, Silybin A+B 9 mg, Vitamin E 13 mg, and Vitamin C 10 mg, while KidneyRx for cats and dogs includes Omega-3, L-Carnitine, and cranberry extract among its ingredients. These do not treat FIP and are never a substitute for antiviral therapy, but they can help support the organs alongside your veterinarian's plan.

How can Filipino Pawrents manage the cost of FIP treatment?

The best way to manage FIP treatment cost is to confirm the diagnosis early, weigh your cat accurately, and get a personalized quote before you start. Early, correct treatment often prevents a case from becoming more advanced and more expensive.

A few practical steps help:

• Get a clear diagnosis of the FIP form as soon as possible.

• Ask for a full 84-day plan so you can budget for the whole journey, not just week one.

• Use the free consultation to match the treatment route to your cat and your budget.

• Lean on the FIP support community; many families here have been where you are.

Honest, open conversations make a real difference, and it helps to know what Philippine veterinarians are telling cat owners about FIP treatment before you decide.

FAQ

How much does FIP treatment cost in the Philippines?

The cost is not a single fixed figure, because it depends on your cat's weight, the FIP form, the treatment route, and the full 84-day protocol. The most accurate way to know your total is a free consultation for a quote based on your cat's exact details.

Why is a heavier cat's treatment more expensive?

Antiviral dosing is calculated per kilogram of body weight, so a heavier cat needs a larger daily dose across all 84 days. This is the single biggest reason two cats with the same diagnosis can have different total costs.

Is there a cheaper form of FIP to treat?

Wet and dry FIP without ocular or neurological signs use lower dosing (6 mg/kg for wet, 8 mg/kg for dry) than ocular and neurological FIP, which are dosed at 10 mg/kg. Since dosing drives cost, the more advanced forms generally need more medication.

Do LiverRx and KidneyRx replace antiviral treatment?

No. LiverRx and KidneyRx are supportive nutraceuticals for organ support only and do not treat FIP. They are used alongside veterinary-guided antiviral treatment, never in place of it.

How long does FIP treatment last?

The standard FIP protocol is 84 days, which is 12 weeks of daily antiviral treatment. Some cats follow a stepped plan guided by their veterinarian based on the FIP form and how the cat responds.
