FAQ
Frequently asked questions about FIP
Clear answers to the most common questions.
Yes. Since 2019, antivirals like GS-441524 have transformed FIP from a death sentence into a treatable disease, with cure rates above 80-90% in many studies. Early diagnosis and access to correct treatment are key factors.
GS-441524 is a nucleoside antiviral that inhibits replication of the feline infectious peritonitis virus. It acts by interfering with the viral RNA polymerase, preventing the virus from replicating. It is administered by subcutaneous injection or orally depending on the case and commercial brand.
Standard treatment lasts 84 days (12 weeks). Some neurological or difficult forms may require extensions of an additional 12 weeks. After treatment ends, a further 84-day follow-up is performed to confirm sustained remission.
There are antiviral brands verified by the global FIP community. In our brands section you'll find information on the most widely used ones. However, we always recommend doing so under veterinary supervision to ensure the correct dose and proper follow-up.
It is technically possible, but we don't recommend it. A vet can confirm the diagnosis, monitor treatment response, adjust doses if necessary, and detect relapses. Many owners work with GS-friendly vets or seek guidance in specialized groups.
