GS-441524 Tablets vs. Injections for FIP: Which Should You Choose?

GS-441524 tablets vs injections for FIP is one of the most important decisions cat owners must make after a FIP diagnosis. While both options use the same antiviral compound, each method offers different advantages depending on your cat’s condition. Read our complete injectable vs oral guide for a full breakdown.

What Is GS-441524?

Both tablets and injections rely on GS-441524, which works by blocking the replication of the mutated feline coronavirus. As a result, your cat’s immune system can regain control and begin recovery. The Pedersen et al. 2019 UC Davis trial established a 92% success rate when administered correctly for the full 84-day protocol.

Can You Combine Both?

Yes — in many cases, combining both methods provides the best outcome. Start with injections for rapid control, then switch to tablets for easier long-term management. Always adjust dosage carefully when switching. Use our dosage calculator and contact FIP Cure Plus before switching methods.

Which Should You Choose?

Consider your cat’s condition (mild vs severe), your ability to administer treatment, and your cat’s tolerance and comfort. Both methods are effective when used properly. With the right approach and the full 84-day protocol, many cats recover fully from FIP.
