GS-441524 – The Gold Standard for FIP

  • GS-441524 is a potent nucleoside analog antiviral that blocks FIP virus replication. It works by mimicking viral RNA building blocks, stopping the disease from spreading.
  • GS‑441524 does not “kill” the virus directly — it stops it from multiplying, letting the cat’s immune system win.

Frequently Asked Questions
What is GS-441524 and how does it treat FIP?
GS-441524 is an effective antiviral agent that targets the feline coronavirus causing FIP. It blocks viral replication, reduces inflammation, and helps your cat recover safely. It is widely recognized as a core treatment for feline infectious peritonitis.
Which form should I choose for my cat's FIP?
Choose injections for wet FIP, neurological FIP, or critical conditions. Choose tablets for mild dry FIP, stable patients, or long-term recovery care. Always follow your vet’s guidance for the best results.
How to dose 55mg GS-441524 tablets for a 4kg cat?
Our 55mg tablet provides an effective 40mg active dose, which is the precise daily dosage for a 4kg cat. No cutting or splitting needed — one tablet per day keeps dosing simple and accurate.
What’s the difference between GS-441524 injection and tablets?
Injections offer faster absorption and higher bioavailability, ideal for acute, wet, or severe FIP. Tablets are easier to give at home, cause less stress, and work well for mild dry FIP or long-term maintenance therapy.
How long should my cat take GS-441524?
The standard treatment duration is 8 to 12 weeks. Do not stop early even if symptoms improve, as premature discontinuation may lead to relapse. Your vet will adjust the length based on your cat’s condition.
Are there any side effects of GS-441524?
Most cats tolerate GS-441524 very well. Mild injection-site redness or slight appetite changes may occur but usually fade quickly. Contact your vet if you notice persistent discomfort or unusual symptoms.
