Cat Feline Infectious Peritonitis Treatment Access

The development of effective antiviral treatment for Feline Infectious Peritonitis (FIP) represents a landmark advance in cat welfare, transforming a uniformly fatal disease into a treatable one.

Key Facts

FIP is caused by a mutant form of feline coronavirus (FCoV) and was previously virtually always fatal
GS-441524 and GS-441524 derivatives have demonstrated cure rates over 90% in clinical studies
Treatment typically requires 84 days of daily injections or oral administration
Access barriers include high cost (thousands of pounds for a course) and regulatory status variation
Generic versions have improved access but quality control varies between suppliers

Welfare Considerations

FIP caused devastating suffering - affected cats experienced fluid accumulation, neurological signs, and progressive deterioration toward death. The emergence of effective antiviral treatment is one of the most significant veterinary welfare advances in decades. However, access barriers mean many cats still die preventably because treatment costs are prohibitive. Improving access through cost reduction, insurance coverage, and veterinary funding schemes is a critical welfare priority.

What You Can Do

Discuss FIP treatment options promptly with your vet if FIP is suspected in your cat
Support organisations advocating for accessible FIP treatment pricing and veterinary funding
Learn about FIP prevention husbandry to reduce FCoV mutation risk in multi-cat environments
Advocate for insurance coverage of FIP treatment to improve access for cats in need
