FIP Treatment Cost and Protocol Length in India: A Plan

Key takeaway: Feline Infectious Peritonitis (FIP) treatment in India follows a standard 84-day (12-week) antiviral protocol built around GS-441524, and the total you plan for is driven mainly by your cat's weight, the form of FIP, and whether your cat needs daily injections, oral capsules, or both. The exact rupee figure varies, so your veterinarian and the BasmiFIP team should confirm it for your cat's weight, but every family can map out the journey in advance. Lead with the plan, and the cost becomes far less frightening.

If you have just heard the letters FIP, take a breath. You are not the first Pawrent to face this, and your cat's odds are better than they have ever been. Since 2019, more than 100,000 cats have been treated, and there is now a clear path forward.

What is Feline Infectious Peritonitis (FIP) and why does the protocol run 84 days?

Feline Infectious Peritonitis (FIP) is a serious viral disease in cats, and the standard antiviral protocol runs for 84 days (12 weeks) of daily treatment. That length is not random. FIP needs sustained antiviral pressure day after day to push the disease into remission and keep it there.

The hero ingredient in BasmiFIP's FIP line is GS-441524, given every day, 7 days a week, for the full 84 days. Skipping days or stopping early is the most common reason a recovery stumbles.

FIP has four forms, and the form your cat has shapes both the treatment and the cost:

• Wet (effusive) FIP: fluid builds up in the abdomen or chest.

• Dry (non-effusive) FIP: no large fluid buildup, but organs are affected.

• Ocular FIP: the eyes are involved.

• Neurological FIP: the brain and nervous system are involved.

Ocular and neurological FIP are two separate forms, and both need higher dosing than wet or dry FIP. Knowing the form early helps you and your veterinarian plan the right route from day one.

How much does FIP treatment cost in India?

FIP treatment cost in India is shaped by three things: your cat's body weight, the form of FIP, and the treatment route (injectable, oral capsules, or a combination). Because GS-441524 is dosed by milligrams per kilogram, a heavier cat simply needs more medicine each day, so weight is the single biggest driver of the total.

There is no one-size-fits-all number, and we will not quote a figure that may not fit your cat. Instead, ask the BasmiFIP team or your veterinarian to calculate your cat's daily dose first, then multiply across the 84-day protocol. That gives you an honest, personalised estimate.

The main cost factors to plan for are:

1. Your cat's weight. Dosing is per kilogram, so a 5 kg cat needs more per day than a 2.5 kg cat.

2. The form of FIP. Ocular and neurological FIP use a higher dose (10 mg/kg), which raises the daily amount.

3. The route. Daily injections, oral capsules, or a combination each have a different cost profile.

4. The full 84 days. Budget for the whole 12 weeks, not just the first few.

5. Veterinary monitoring. Bloodwork and check-ups during and after treatment are part of a safe journey.

We are affordability-aware, and we know many families in India are cost-conscious. The goal is a path you can trust and sustain to the end, because a completed protocol is what protects your spending and your cat.

What does BasmiFIP's GS-441524 treatment include?

BasmiFIP's primary FIP antiviral is GS-441524 injectable, supplied at 40 mg/ml, 99.4% purity, in an 8 ml vial. It is the backbone of the 84-day protocol and the form most used for ocular and neurological FIP.

The daily dose depends on the form of FIP your cat has:

Form of FIP	GS-441524 injectable dose	Route notes
Wet (effusive)	6 mg/kg daily	Oral options may suit stable cats
Dry (non-effusive)	8 mg/kg daily	Oral options may suit stable cats
Ocular	10 mg/kg daily	Injectable start recommended
Neurological	10 mg/kg daily	Injectable start recommended

For cats with wet or dry FIP and no ocular or neurological signs, BasmiFIP also offers oral options. EIDD-1931 oral capsules (15 mg per capsule) are indicated for wet and dry FIP only, and a Dual Antiviral capsule combines GS-441524 with EIDD-1931 for one capsule a day once a cat is stable.

Important safety note: EIDD-1931 capsules are not recommended for ocular or neurological FIP, and not for cats that are not eating or defecating normally. EIDD-1931 should also never be given to pregnant, nursing, or breeding cats.

Should my cat start on injections or oral capsules?

Whether your cat starts on injections or oral capsules depends on the form of FIP and how stable your cat is right now. As a general rule, ocular and neurological FIP, and any cat not eating or pooping normally, should start on GS-441524 injections, while stable wet or dry FIP may begin on oral capsules.

Here is the regimen logic many families follow with their veterinarian:

• Wet or dry FIP, no ocular or neurological signs: may start EIDD-1931 for the first 30 days. If symptoms persist, extend treatment. If they continue past 60 days, switch to GS-441524 at 10 mg/kg.

• Ocular or neurological FIP, or a cat not eating or defecating normally: start GS-441524 injections for 30 days, then may switch to the GS-441524 Dual Antiviral capsule once stable.

The Dual Antiviral capsule is designed for after about 30 days of injections, or once a cat is stable. It is not used during ocular or neurological symptoms, during vomiting or diarrhea, or for cats under 1 year with wet FIP.

For many Pawrents, a short injectable phase followed by oral capsules is both gentler on the cat and easier on the budget for the back half of the protocol. Your veterinarian will help you time the switch safely.

How effective is FIP treatment, and what are the real numbers?

FIP treatment today has a strong track record, and the figures are what give families hope. In a UC Davis clinical trial, GS-441524 reached a 92% success rate, and that is the headline figure behind the modern approach to FIP.

For the combination route, a dual-antiviral field study by Li and Cheah (2025) reported 78.3% remission using GS-441524 together with EIDD-1931. These are two different studies measuring two different things, so we keep the numbers separate rather than blending them.

Across the wider community, more than 100,000 cats have been treated since 2019. You are joining a large, experienced group of families, and that shared experience is one of your best resources.

We never use the word cure, because FIP care is about achieving and holding remission through a complete protocol and careful monitoring. That honesty is part of why families trust the journey.

How can I keep FIP treatment affordable without cutting corners?

The most reliable way to protect both your cat and your budget is to complete the full 84-day protocol the first time, because a stopped-and-restarted treatment often costs more in the end. Plan for the whole 12 weeks up front, then break it into weekly steps you can manage.

Practical ways to plan ahead:

1. Get an accurate weight. Weigh your cat before you start so the daily dose and total are calculated correctly.

2. Confirm the form of FIP with your veterinarian. This decides the dose and the route.

3. Budget for all 84 days at once. Treat the full protocol as the plan, not the first week.

4. Buy from verified sources only. If you are comparing suppliers, read this guide to buying GS-441524 online safely in India before you order.

5. Set aside funds for monitoring. Bloodwork during and after treatment keeps the journey safe.

Weight gain during recovery is a good sign, and it can also raise the daily dose as your cat grows stronger. Reweigh regularly with your veterinarian so dosing stays accurate.

Does my cat need anything besides the antiviral?

Some cats benefit from supportive organ care alongside antiviral treatment, and BasmiFIP offers RX Sciences nutraceuticals for exactly this. LiverRx and KidneyRx are adjunct support products, not antivirals, and they do not treat FIP on their own.

LiverRx for cats and small dogs contains SAMe 90 mg, Silybin A and B 9 mg, Vitamin E 13 mg, and Vitamin C 10 mg, in a 30-tablet pack. KidneyRx for cats and dogs combines ingredients such as L-Carnitine 25 mg, Omega-3 50 mg, and Cranberry extract 25 mg, in a 60-tablet pack.

Always run supportive products past your veterinarian first, so they fit your cat's overall plan.

One more safety reminder for the FIP journey: during antiviral treatment, avoid fluoroquinolone antibiotics, spot-on flea medications, lysine, and immune boosters, as these can interfere with recovery.

FAQ

How long does Feline Infectious Peritonitis (FIP) treatment take?

The standard FIP antiviral protocol runs for 84 days, which is 12 weeks of daily treatment. Finishing the full course is essential, even when your cat looks and feels much better partway through.

What makes FIP treatment cost more for some cats?

FIP treatment cost rises mainly with your cat's body weight, because GS-441524 is dosed per kilogram, so heavier cats need more medicine each day. Ocular and neurological FIP also use a higher dose (10 mg/kg), which increases the daily amount compared with wet or dry FIP.

Can I treat FIP with oral capsules instead of injections?

Stable wet or dry FIP may be treated with oral options such as EIDD-1931 capsules or the GS-441524 Dual Antiviral capsule, but ocular and neurological FIP, and cats not eating or defecating normally, should start on GS-441524 injections. Your veterinarian will decide the safest route and when a switch is appropriate.

How effective is GS-441524 for FIP?

In a UC Davis clinical trial, GS-441524 reached a 92% success rate, and a separate dual-antiviral field study by Li and Cheah (2025) reported 78.3% remission with GS-441524 combined with EIDD-1931. These numbers come from two different studies and are not interchangeable.

Is any FIP capsule unsafe for pregnant cats?

Yes. EIDD-1931 products should never be given to pregnant, nursing, or breeding cats. Tell your veterinarian if your cat is or may be pregnant so a safe plan can be chosen.
