What Is the Cost of FIP Treatment for Cats in India?

The cost of Feline Infectious Peritonitis (FIP) treatment in India depends mostly on three things: your cat's weight, which of the four forms of FIP your cat has, and the length of the standard 84-day protocol. Because the antiviral dose is calculated per kilogram, a heavier cat or a case with ocular or neurological signs needs more medicine, which raises the total. For an exact figure, your veterinarian and the BasmiFIP team can work out a plan based on your cat's weight and diagnosis.

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.

What determines the cost of FIP treatment in India?

The cost of FIP treatment in India is driven by dose, duration, and the form of the disease, not by a single flat price. Because GS-441524 is dosed by body weight and given daily across a 12-week protocol, the total scales with how much your cat weighs and how long treatment runs.

Here are the main factors that shape the total:

• Your cat's weight. Dosing is per kilogram, so a 2 kg kitten needs far less medicine than a 6 kg adult.

• The form of FIP. Wet and dry FIP use lower per-kilogram doses than ocular and neurological FIP.

• The treatment route. Daily GS-441524 injections, oral capsules, or a combination each carry a different cost profile.

• The full 84-day protocol. The standard FIP protocol runs 84 days (12 weeks), and finishing it fully matters for a lasting recovery.

• Diagnostics and monitoring. Blood tests, vet consultations, and follow-up checks add to the journey but keep it safe.

Because every cat is different, the safest way to estimate cost is to have your veterinarian confirm the diagnosis and weight, then map out the protocol from there.

Why does the form of FIP change the cost?

The form of FIP changes the cost because each form is dosed at a different milligram-per-kilogram level, and higher doses use more medicine. FIP has four separate forms, and the antiviral requirement rises as you move from wet FIP up to neurological FIP.

The four forms of FIP are:

1. Wet (effusive) FIP, where fluid builds up in the abdomen or chest.

2. Dry (non-effusive) FIP, without obvious fluid.

3. Ocular FIP, affecting the eyes.

4. Neurological FIP, affecting the brain and spinal cord.

Ocular and neurological FIP are two distinct forms, and both require higher GS-441524 dosing than wet or dry FIP. That higher dose is why these cases usually cost more per day of treatment.

FIP form	GS-441524 injectable dose	Typical starting approach
Wet (effusive)	6 mg/kg daily	May begin with oral therapy if the cat is eating and pooping normally
Dry (non-effusive)	8 mg/kg daily	May begin with oral therapy if stable
Ocular	10 mg/kg daily	Start with GS-441524 injections
Neurological	10 mg/kg daily	Start with GS-441524 injections

Because dose depends on weight and form, ask your veterinarian to confirm both before you estimate the budget. You can read more about how vets across the country manage these cases in these lessons from Indian veterinary clinics.

What are the BasmiFIP treatment options and how do they differ?

BasmiFIP offers three antiviral options for FIP, and the right one depends on the form of FIP and how stable your cat is. GS-441524 is the primary, hero antiviral, and it can be given as an injection, while EIDD-1931 and a dual capsule cover certain stages of treatment.

The options are:

• GS-441524 injectable (Basmi FIP Antiviral): 40 mg/ml, 99.4% purity, in an 8 ml vial. Given as a daily injection, 7 days a week, for the full 84-day protocol. This is the go-to for ocular and neurological FIP, and for cats who are not eating or defecating normally.

• EIDD-1931 oral capsules: 15 mg per capsule, 60 capsules per box. Indicated for wet and dry FIP only. Not for ocular or neurological FIP, and not for cats who are not eating or pooping normally.

• Dual Antiviral oral capsules (GS-441524 + EIDD-1931): one capsule per day, usually introduced after about 30 days of injections or once the cat is stable.

EIDD-1931 is potent. It is roughly 7.3 times more potent than GS-441524 by weight, which is one reason oral options can be efficient for suitable wet and dry cases.

Important safety note: EIDD-1931 is potentially teratogenic, so no EIDD-1931 product should be used for pregnant, nursing, or breeding cats. Your veterinarian will guide the safest route for your cat.

How does the treatment route affect what you pay?

The treatment route affects cost because injections, oral capsules, and combination therapy each use different amounts and forms of medicine over the 84 days. Injections deliver GS-441524 directly and are essential for ocular and neurological cases, while oral capsules can suit stable wet and dry cases.

A common, vet-guided regimen logic looks like this:

1. Wet or dry FIP with no ocular or neurological signs: may start with EIDD-1931 for 30 days, extend if symptoms persist, and if they continue past 60 days, switch to GS-441524 at 10 mg/kg.

2. Ocular or neurological FIP, or a cat not eating or pooping normally: start with GS-441524 injections for 30 days, then may switch to the GS-441524 dual antiviral capsule once stable.

Because the route can change partway through the journey, the total is best viewed across the whole 84 days rather than day one alone. A detailed walkthrough is in this comprehensive guide to dual antiviral therapy for cat parents in India.

Does a heavier cat cost more to treat?

Yes, a heavier cat generally costs more to treat because both injectable and capsule dosing scale with body weight. More kilograms means more milligrams of antiviral each day, and that adds up across 84 days.

Oral dosing is banded by weight, which makes planning simpler:

Weight band	EIDD-1931 capsules (15 mg)	Dual Antiviral capsule (once daily)
Under 2.5 kg	1 capsule every 12 hours	GS 25 mg + EIDD 5 mg
2.5 to 5 kg	2 capsules every 12 hours	GS 35 mg + EIDD 8 mg
Over 5 kg	3 capsules every 12 hours	GS 50 mg + EIDD 10 mg

Weigh your cat accurately before you estimate cost, and reweigh through treatment, since a recovering cat often gains weight and the dose may need adjusting. Your veterinarian will confirm the right amount at each stage.

Are there hidden costs beyond the medicine?

Yes, beyond the antiviral itself, plan for diagnostics and monitoring, which protect your cat and confirm progress. These usually include the initial diagnosis, periodic blood work, and vet consultations across the 12 weeks.

Typical additional items are:

• Diagnosis and confirmation by your veterinarian.

• Blood tests during treatment to track recovery markers.

• Follow-up consultations through the protocol and after it ends.

• Supportive care if your vet recommends it for organ health.

Monitoring is not wasted money. Knowing your cat's numbers is how you and your vet decide when to adjust dose or move between routes. This guide on FIP blood test results during treatment explains what those numbers mean.

Where do supportive nutraceuticals fit into the budget?

Supportive nutraceuticals like LiverRx and KidneyRx are optional adjuncts for organ support, not antivirals, and they do not treat FIP. They may be added alongside veterinary-guided antiviral treatment when your vet feels liver or kidney support is helpful.

• LiverRx (cats and small dogs): SAMe 90 mg, Silybin A+B (milk thistle) 9 mg, Vitamin E 13 mg, Vitamin C 10 mg; 30 tablets.

• KidneyRx (cats and dogs): Magnesium carbonate 10 mg, Vitamin D 50 IU, Calcium carbonate 15 mg, L-Carnitine 25 mg, Chitosan 25 mg, Omega-3 50 mg, Cranberry extract 25 mg; 60 tablets.

These are a small, separate line item. The antiviral protocol remains the core of your cat's recovery journey.

Is FIP treatment worth the cost?

Many families in India tell us that completing the protocol was worth it, and the track record is why. Since 2019, more than 100,000 cats have been treated with GS-441524, and the success rate has changed what this diagnosis means.

Here are the headline figures, kept separate as they should be:

• 92% success rate for GS-441524, reported in the UC Davis clinical trial.

• 78.3% remission in a dual-antiviral field study combining GS-441524 and EIDD-1931 (Li and Cheah 2025), which included some drug-resistant cases.

Those two numbers come from two different studies and should never be blended. You can read the BasmiFIP dual antiviral study on 78.3% remission for the full detail.

A quick safety reminder for cost planning: during FIP treatment, avoid fluoroquinolone antibiotics, spot-on flea medications, lysine, and immune boosters, since your vet will want a clean protocol.

FAQ

How much does FIP treatment cost in India?

There is no single flat price, because cost depends on your cat's weight, the form of FIP, and the 84-day protocol length. Your veterinarian and the BasmiFIP team can calculate an estimate once weight and diagnosis are confirmed.

Why is neurological or ocular FIP more expensive to treat?

Neurological and ocular FIP are dosed at 10 mg/kg of GS-441524, higher than the 6 mg/kg for wet or 8 mg/kg for dry FIP. Higher doses use more medicine each day, which raises the total across the protocol.

Is oral treatment cheaper than injections?

Not always, because the total depends on weight, duration, and the form of FIP rather than route alone. Oral EIDD-1931 capsules suit stable wet and dry cases, while ocular and neurological FIP need GS-441524 injections, so your vet will match the route to the case.

How long does FIP treatment last?

The standard FIP protocol runs 84 days, which is 12 weeks. Completing the full course is important, and stopping early can put your cat's recovery at risk, so plan the budget for the whole protocol.

Do LiverRx and KidneyRx treat FIP?

No, LiverRx and KidneyRx are supportive nutraceuticals for organ health, not antivirals, and they do not treat FIP. They may be used alongside veterinary-guided antiviral treatment if your vet recommends them.

You do not have to figure out the cost alone, and there is a clear path forward that starts with the right diagnosis. To understand the options for your cat's weight and form of FIP, and to plan a budget you can manage, talk with the BasmiFIP India team or your own veterinarian. Every treatment decision should be made with your veterinarian, who knows your cat best.
