CE AR TREBUI SĂ ȘTIȚI DESPRE TRATAMENTUL PIF

Durata recomandată a tratamentului este de 12 săptămâni. Cu toate acestea, durata reală a tratamentului poate depinde de mulți factori, cum ar fi cât de repede răspunde pisica la tratament, stadiul infecției cu PIF în care începe tratamentul și situația dumneavoastră financiară personală.

Da, GS este un tratament antiviral și poate fi utilizat împreună cu alte medicamente pentru a îmbunătăți starea generală de sănătate a pisicii dumneavoastră. Cu toate acestea, nu se recomandă utilizarea lizinei împreună cu GS.

Pește proaspăt gătit și alte alimente naturale. Dacă pisica ta are diaree, ia în considerare trecerea la hrană uscată timp de câteva zile, până când diareea se oprește.

Pe măsură ce pisica ta începe să se vindece, va lua în greutate pe măsură ce îi revine pofta de mâncare și alimentația normală se reia. Cântăriți pisica o dată pe săptămână și ajustați doza de medicament în consecință. Mențineți legătura strânsă cu medicul veterinar, astfel încât orice potențiale complicații, cum ar fi leziuni hepatice și renale sau infecții, să poată fi abordate.

Early symptoms common to both wet and dry FIP include persistent fever that does not respond to antibiotics, unexplained weight loss, loss of appetite, lethargy, and dull coat condition.

In wet FIP, additional signs include a visibly swollen or distended abdomen, laboured breathing (if fluid accumulates in the chest), and general weakness. In dry FIP, symptoms vary widely depending on which organs are affected — these can include neurological signs such as wobbling, tremors, or seizures; eye changes such as cloudiness, uneven pupil size, or inflammation; jaundice; or unexplained changes in behaviour.

If your cat is displaying any combination of these signs — particularly persistent fever alongside weight loss and lethargy — contact your veterinarian promptly. Early diagnosis significantly improves treatment outcomes.

FIP presents in two primary forms. Wet (effusive) FIP is characterised by fluid accumulation in the abdomen or chest cavity, and tends to progress rapidly. Dry (non-effusive) FIP involves inflammatory lesions in organs without significant fluid build-up, and typically progresses more slowly.

Both forms are treated with GS-441524 using the same core protocol. What changes is the starting dose and urgency of treatment. Neurological and ocular FIP — which can occur in either form — require higher doses and must be treated with injections only. If you are unsure which form your cat has, share your cat's diagnosis and bloodwork with our treatment team and we will advise on the correct protocol.

FIP develops when the feline enteric coronavirus (FCoV) — a common intestinal virus that most cats carry without ever falling ill — undergoes a mutation inside the cat's body. This mutation transforms it into the feline infectious peritonitis virus (FIPV), which triggers a severe immune response and attacks the cat's own tissues.

FCoV itself is contagious and spreads between cats through shared litter boxes, food and water bowls, and close contact — particularly in multi-cat households, shelters, and catteries. However, FIP itself does not spread directly from cat to cat. The mutation that causes FIP occurs randomly and cannot be predicted. Young cats under two years old, males, and purebred cats are at statistically higher risk of developing FIP after FCoV exposure.

This is one of the most common and understandably confusing questions from cat owners. FIP can develop in indoor cats because the feline coronavirus (FCoV) that causes it is extremely widespread — many cats are exposed in early life, particularly if they came from a breeder, cattery, shelter, or multi-cat household before joining your home.

FCoV can remain dormant in a cat's body for months or years before the random mutation event that triggers FIP. An indoor cat that has had no outside contact in years can still develop FIP from a coronavirus exposure that happened much earlier in its life. It is not a sign that anything went wrong in your care — the mutation is unpredictable and not preventable once FCoV exposure has occurred.

FIP itself is not directly transmitted between cats. What spreads between cats is the underlying feline coronavirus (FCoV), which in most cases causes no symptoms at all. The mutation that transforms FCoV into FIP occurs spontaneously inside an individual cat's body and cannot be passed on.

FCoV is shed in faeces and spreads through shared litter boxes, grooming, and close contact. Managing hygiene in multi-cat environments — particularly litter box cleanliness — is the primary way to limit FCoV circulation and reduce the overall risk of any individual cat developing FIP.

FIP itself is not directly contagious between cats. However, the underlying feline coronavirus (FCoV) that mutates into FIP is contagious and is commonly spread through shared litter boxes, food bowls, and close contact.

Most cats that carry FCoV never develop FIP — only a small percentage experience the viral mutation that causes the disease. During your cat's FIP treatment, standard hygiene precautions are sufficient: keep litter boxes clean, wash food and water bowls regularly, and monitor other cats in the household for any changes in behaviour, appetite, or weight. If another cat in your home develops symptoms, contact us promptly.

There is no single definitive test for FIP. Diagnosis typically involves a combination of approaches:

Blood tests are usually the starting point — looking at the albumin-to-globulin (A/G) ratio, white blood cell count, protein levels, and inflammatory markers. A low A/G ratio combined with clinical signs strongly suggests FIP. The Rivalta test can be performed on fluid from effusive cases and has high specificity for FIP. Immunofluorescence testing on fluid or tissue samples can detect the FIPV antigen directly. Advanced tools such as AGP testing and FIPV RT-PCR on effusion fluid provide greater certainty. In unclear cases, biopsy of affected tissue remains the most definitive method of confirmation.

If you suspect FIP, work with your veterinarian to build a diagnostic picture — no single result rules it in or out on its own.

There is currently no guaranteed method to prevent FIP, as the mutation from feline coronavirus to FIPV occurs unpredictably. However, the following measures reduce the risk of FCoV exposure and transmission:

Keep litter boxes clean and disinfect them regularly. Avoid overcrowding — FCoV spreads more readily in high-density cat environments such as shelters and multi-cat households. When introducing a new cat, isolate them initially and have them tested for FCoV before mixing with resident cats. Reducing environmental stressors, which are known to increase viral susceptibility, also plays a supporting role. A FIP vaccine exists in some markets but has shown limited effectiveness in clinical practice and is not widely recommended.

Without treatment, the prognosis for FIP is extremely poor. Wet FIP progresses rapidly — most untreated cats survive only days to a few weeks after symptoms appear. Dry FIP progresses more slowly, but remains fatal without antiviral intervention. The median survival time from diagnosis without treatment is approximately 9 days.

With GS-441524 treatment, the outlook has changed dramatically. The majority of cats that complete the full 84-day protocol reach sustained remission and go on to live normal, healthy lives. Treatment should begin as early as possible — delay reduces the likelihood of a full response, particularly in advanced or neurological cases. Contact our treatment team immediately if your cat has been diagnosed or you suspect FIP.

Yes. The majority of cats that complete a full course of GS-441524 treatment go on to live normal, healthy lives. In clinical studies, most cats in sustained remission after the 84-day protocol show no long-term health consequences from the infection itself.

Some cats experience residual effects from organ involvement during the active disease phase — particularly in cases with neurological or ocular complications — but these typically resolve or stabilise after treatment ends. Weight regained during treatment is usually maintained. Most owners report that their cats return fully to pre-FIP behaviour within weeks of completing the protocol.

Completing the 84-day protocol is the end of active treatment, not the end of monitoring. After your cat finishes the course, a 12-week observation period begins. During this period, your cat should not be on any antiviral medication. If no signs of FIP return during those 12 weeks — no fever, no weight loss, no fluid accumulation, and no changes in behaviour — your cat is considered in sustained remission.

Bloodwork at the end of treatment and again at the end of the observation period will confirm remission. Do not stop treatment early based on clinical appearance alone — many cats look healthy before the virus is fully suppressed. Stopping short increases the risk of relapse.

The total cost of treatment depends on your cat's weight, the FIP type, and whether you use injectables or oral capsules. For a standard 84-day course, most owners should budget for 3 monthly packs of capsules or the equivalent in injectable vials, adjusted for their cat's weight bracket.

We recommend ordering all 3 packs at the start of treatment to avoid any supply interruption mid-course. If cost is a concern, contact our treatment team — we can discuss the most efficient treatment configuration for your cat's weight and condition. We also encourage owners with unused medication after a completed treatment to donate it to families who cannot afford a full course.

The earliest signs of FIP are often non-specific and easy to overlook. Persistent fever that does not respond to antibiotics is typically the first indicator. This is usually accompanied by loss of appetite, unexplained weight loss, lethargy, and a dull or unkempt coat. Some cats also develop mild digestive upset in the early stages.

As the disease progresses, more specific signs emerge depending on the form. In wet FIP, a visibly swollen or distended abdomen develops as fluid accumulates. In dry FIP, signs vary more widely and may include neurological changes such as loss of coordination, tremors, or seizures, as well as eye abnormalities like cloudiness or uneven pupil size. If your cat is showing any combination of these early signs — especially persistent fever alongside weight loss — contact your veterinarian immediately. Early diagnosis and prompt treatment significantly improve outcomes.

Yes — with treatment. FIP was once considered almost universally fatal, and without antiviral intervention it still carries an extremely poor prognosis. The median survival time without treatment is approximately 9 days from the point of diagnosis.

With GS-441524 antiviral treatment, the outcome has changed fundamentally. Across multiple independent clinical studies covering over 650 cats, the combined treatment success rate is approximately 92%. The majority of cats that complete the full 84-day protocol reach sustained remission and go on to live normal, healthy lives. The key factors that determine survival are starting treatment as early as possible, dosing correctly by body weight throughout the protocol, and completing the full 84 days without interruption. If your cat has been diagnosed with FIP, contact our treatment team immediately — time is the most critical variable.

WHAT YOU SHOULD KNOW ABOUT FIP TREATMENTS

The standard treatment course is 84 days (12 weeks). Most cats complete the full protocol and achieve remission within this period.

In practice, treatment duration can vary. Cats that begin treatment in the early stages of FIP typically respond faster. Those with advanced disease, neurological involvement, or ocular complications may require an extended course beyond 84 days. Your cat's bloodwork and clinical response at regular checkpoints will guide any adjustments.

GS-441524 is an antiviral and is generally compatible with other medications used to support your cat's overall health during treatment.

One exception: lysine is not recommended alongside GS-441524. Research has shown that lysine supplementation does not benefit cats with viral infections and may interfere with treatment. If your cat is currently taking lysine, discontinue it before starting the FIP treatment protocol.

If you are unsure whether a specific medication or supplement is compatible with GS-441524, contact our treatment team before combining.

Nutrition plays an important supporting role during treatment. High-quality protein helps maintain body weight and supports immune function — cooked fresh fish, chicken, or other natural whole foods are good options and are generally well tolerated.

Appetite loss is common in FIP cats, particularly in the early weeks of treatment. If your cat is reluctant to eat, warming the food slightly or offering smaller, more frequent meals can help stimulate interest.

If your cat develops diarrhea during treatment, temporarily switching to a dry food diet for a few days can help firm the stool. If diarrhea persists beyond 48 hours or is accompanied by lethargy or vomiting, contact our treatment team — it may indicate a dosing or absorption issue that needs attention.

Avoid raw fish during treatment. Raw fish contains thiaminase, an enzyme that breaks down thiamine (Vitamin B1), which can cause neurological complications in cats already under systemic stress.

As treatment takes effect, you will typically see your cat's appetite return and body weight increase — both are positive signs of recovery. Weigh your cat once a week throughout the treatment course and adjust the dosage accordingly, as GS-441524 and E

TRATAMENT INJECȚIONAL

Concentrațiile mai mari sunt mai potrivite pentru pisicile mai mari și/sau cele care suferă de simptome FIP mai severe.

O injecție pe zi, în funcție de greutatea corporală a pisicii dumneavoastră, timp de 12 săptămâni.

Pentru a calcula doza, vă rugăm să utilizați calculatorul nostru de doze. Nu recomandăm scăderea dozei în timpul tratamentului, deoarece aceasta poate crește rezistența virală la medicamentul GS.

Urmăriți videoclipul nostru instructiv pentru instrucțiuni pas cu pas despre cum să efectuați injecții subcutanate acasă.

TRATAMENT ORAL

Pentru cele mai bune rezultate, utilizați capsulele la 30 de zile după tratamentul injectabil sau după ce starea de sănătate a pisicii s-a stabilizat: alimentație sănătoasă, scaun normal și absența simptomelor neurologice.

Atâta timp cât pisica prezintă încă simptome oculare sau neurologice
În timp ce pisica suferă de diaree sau vărsături intermitente.
Dacă pisica nu mănâncă și necesită hrănire forțată sau administrare subcutanată de lichide.

Administrați 1 capsulă pe zi. Respectați un program și nu omiteți nicio zi de medicație. Continuați timp de 84 de zile sau până când toate simptomele PIF au dispărut.

Ar trebui să treceți la o concentrație mai mare, în funcție de greutatea actuală a pisicii dumneavoastră. De exemplu, dacă pisica dumneavoastră a crescut de la 2,4 kg la 2,8 kg, se recomandă să treceți de la capsulele roz la cele verzi. Acest lucru vă asigură că pisica dumneavoastră primește suficiente ingrediente active pentru tratament.

O cutie conține 14 capsule și este suficientă pentru 14 zile de tratament.

Lipsa de ameliorare sau agravarea stării sunt cauzate de o doză insuficientă sau de o absorbție slabă în sistemul digestiv al pisicii. Ar trebui să administrați pisicii dumneavoastră capsule timp de cel puțin 5 zile înainte de a determina dacă nu există o ameliorare. După 5 zile fără o ameliorare vizibilă a simptomelor, puteți crește doza de la 1 capsulă la 2 capsule pe zi sau puteți trece la o concentrație mai mare. Cea mai bună opțiune este trecerea la injecții, deoarece acestea sunt cea mai fiabilă metodă de administrare a dozei adecvate de ingrediente farmaceutice active în organismul pisicii dumneavoastră.

Fiecare pisică are o rată diferită de absorbție a capsulei, în funcție de genetica și factorii de sănătate. Absorbția exactă poate fi determinată printr-o procedură de diagnostic complexă și costisitoare numită cromatografie lichidă de înaltă performanță (HPLC).

Fiecare opțiune de tratament are avantajele și dezavantajele sale. Ambele sunt eficiente în tratarea peritonitei infecțioase feline (PIF). Injecțiile sunt precise, mai ușor de controlat, iar efectele lor sunt imediate. Recomandăm începerea tuturor tratamentelor pentru PIF cu injecții. Capsulele orale sunt mai ușor de administrat, nedureroase și pot fi făcute cu ușurință acasă. Cu toate acestea, GS-441524 va ajunge în fluxul sanguin în mai mult timp, deoarece trebuie să treacă mai întâi prin sistemul digestiv. De asemenea, este imposibil de știut cât de mult din GS-441524 va fi absorbit pentru a combate PIF. Recomandăm începerea administrării capsulelor numai dacă starea pisicii este stabilă. Virusul peritonitei infecțioase feline afectează frecvent organele din sistemul digestiv, cum ar fi stomacul, intestinele, rinichii și ficatul, apoi se răspândește în tot corpul. Organele deteriorate reduc funcția digestivă și pot duce la o absorbție slabă a GS-441524 în fluxul sanguin. Atunci când capsulele sunt administrate prea devreme în tratament, acest lucru poate provoca un tratament prelungit sau o probabilitate mai mare de recidive viitoare.

Puteți trece la tratamentul injectabil după începerea tratamentului oral. Cu toate acestea, doza injectabilă va începe de la 10 mg/kg după trecerea de la tratamentul oral la cel injectabil. Acest lucru se datorează faptului că capsulele noastre au o concentrație mai mare decât tratamentul injectabil. Vă rugăm să ne consultați cu privire la doza injectabilă la care doriți să treceți pentru pisica dumneavoastră.

Nu recomandăm utilizarea capsulelor pentru recidive. Trebuie să utilizați injecțiile și să administrați 12 mg-15 mg pentru tratamentele recidivelor. Vă rugăm să ne consultați cu privire la modul adecvat de tratare a cazurilor recidivate de PIF.

Da, dar folosiți doar capsule dintr-o clasă superioară celei recomandate pentru greutatea pisicii dvs. și niciodată una inferioară. Rețineți că o doză mai mare costă mai mult, cu excepția cazului în care există o nevoie dovedită care face ca achiziționarea de capsule din clasa superioară să fie o risipă de bani.

Pisicile prezintă de obicei o îmbunătățire în 10-15 zile de tratament oral. Unele pisici prezintă o îmbunătățire în doar 5 zile.

Nu există efecte secundare cunoscute la utilizarea tratamentului oral. Îl puteți utiliza împreună cu alte tratamente și suplimente recomandate de medicul veterinar.

Pentru cele mai bune rezultate, tratamentul oral trebuie administrat în decurs de 3 ore, de la ultima administrare din ziua precedentă. Alternativ, poate fi administrat cu 1,5 ore mai devreme sau cu 1,5 ore mai târziu decât în ziua precedentă.

Nu acceptăm ambalaje deschise sau parțial consumate. Recomandăm donarea acestora medicilor veterinari sau altor proprietari de pisici cu PIF, astfel încât să poată fi folosite pentru a ajuta la salvarea pisicilor.
