Quick answer

GS-441524 is not currently licensed as a veterinary medicine in Poland, but Polish cat owners can access it legally through a documented route: a Polish weterynarz (vet) confirms the FIP diagnosis and supervises treatment, and the medicine itself is sourced from a verified EU supplier with a Certificate of Analysis. The 84-day treatment protocol (Pedersen et al., UC Davis, 2019) achieves remission rates above 85% in published trials and is now standard of care in modern Polish small-animal practice. FipDr ships discreetly to all Polish postcodes and pairs every order with a free vet-backed consultation.

If your cat has been diagnosed with FIP (Zakaźne Zapalenie Otrzewnej u Kotów) — the Polish clinical name — this guide explains your real options in 2026.

How FIP treatment in Poland has changed

Polish veterinary medicine has moved quickly on FIP since 2020. Five forces shaped the current 2026 landscape: Pedersen 2019 (the foundational evidence base, now widely cited in Polish veterinary CPD); FIP Warriors Polska (one of the most active national FIP support communities in Central Europe); crowdfunding norms like zrzutka.pl made treatment financially reachable for thousands of Polish families; university adoption at veterinary faculties in Warszawa (SGGW), Wrocław (UPWr), Lublin (UP), Olsztyn (UWM), and Poznań (UPP); and EU regulatory shifts including the 2024 French magistral preparation that Polish vets reference when explaining the treatment.

GS-441524 is not licensed in Poland as a veterinary medicine, but it is administered in clinical practice across the country every day. The legal framework operates through documented veterinary oversight and verified product sourcing.

Forms of FIP and what they mean for treatment

FIP mokra / wysiękowa: wet FIP, with abdominal or thoracic effusion
FIP sucha: dry FIP, granulomatous, often harder to diagnose
FIP oczna: ocular FIP, uveitis, eye involvement
FIP neurologiczna: neurological FIP, ataxia, seizures, behavioral changes

The medicine is GS-441524 across all four forms. Dose differs: wet/dry typically 6 mg/kg/day, ocular 8 mg/kg/day, neurological 10 mg/kg/day or higher. See Wet FIP vs Dry FIP: The 2026 Definitive Comparison Guide.

How Polish cat owners access GS-441524 in 2026

A Polish weterynarz confirms FIP diagnosis and remains the clinical owner of the case. You order GS-441524 from a verified EU supplier (FipDr included) — third-party HPLC-tested, COA per batch, shipped from EU dispatch hub directly to your Polish address. Free consultation throughout the 84 days. Used by the majority of FIP Warriors Polska members in 2026.

A small minority of Polish owners arrange cross-border import of the French magistral preparation (Pharmacie Delpech, Paris). More expensive, slower, and only available as oral suspension.

What FIP treatment costs in Poland (2026 numbers)

FipDr verified supplier + free consultation: €1,800–2,400 (~8,000–10,500 PLN), 2–4 days to most Polish postcodes
French magistral preparation (Delpech): €3,500–5,000 (~15,000–22,000 PLN), 7–14 days

PLN conversion shown for orientation only — final charges are in EUR at checkout. Polish bloodwork at a private weterynaria adds approximately 400–1,200 PLN across the four scheduled draws (day 0, 28, 56, 84). For a deeper breakdown, see FIP Treatment Cost in Europe.

Working with your Polish weterynarz

Polish veterinarians, particularly those affiliated with the Krajowa Izba Lekarsko-Weterynaryjna (KIWL) and graduates of the five Polish veterinary faculties, are generally well-informed about modern FIP management. Confirm diagnosis with appropriate tests (effusion analysis, Rivalta, cytology, A:G ratio, serum AGP, abdominal ultrasound). Bring published evidence (Pedersen 2019, ABCD 2025 guidelines, batch COA). Loop FipDr's vet team in if your local weterynarz has not managed a FIP case before.

Questions Polish cat owners ask most

Czy GS-441524 jest legalny w Polsce?

GS-441524 is not currently licensed as a veterinary medicine in Poland. It is administered in clinical practice through a documented route: a Polish weterynarz diagnoses and supervises; the medicine is sourced from a verified EU supplier with a Certificate of Analysis.

Ile trwa leczenie?

84 days of daily dosing, followed by an 84-day observation window. Total: 168 days. Bloodwork at day 0, 28, 56, 84, then monthly during observation.

Will zrzutka.pl or another crowdfunding platform help?

zrzutka.pl is the most widely used crowdfunding platform in Poland for FIP treatment costs. Many Polish FIP families fund 60–100% of treatment through community donations. We can help structure the financial picture for a zrzutka campaign.

My cat is a Polish rescue (z fundacji) — does that change anything?

No. The biology of FIP and response to GS-441524 are the same regardless of where the cat came from. Rescue cats are slightly over-represented in FIP statistics because feline coronavirus circulates more in colony settings — but treatment and outcome expectations are identical.

What about kittens?

Kittens under 6 months often respond very well to GS-441524 — sometimes faster than adults — but require careful weight-based dose recalculation since they grow each week. See FIP in Kittens.

Counterfeit product is a real risk in the Polish market

Polish FIP support groups (FIP Warriors Polska, regional Telegram channels) have repeatedly warned about counterfeit and underdosed GS-441524 from informal sellers. Underdosed product is worse than no product — it allows viral mutation against the drug. Verify any supplier has third-party HPLC purity testing (≥99%), endotoxin testing, COA for your specific batch, documented chain of custody, and a licensed vet you can speak with. FipDr provides all five. See How to Buy GS-441524 in Europe Safely.
