Can FIP Tablets Cure My Cat? Everything Cat Owners Should Know

Hearing that your cat has FIP (Feline Infectious Peritonitis) can be devastating. For many years, it was considered a fatal disease. But thanks to groundbreaking antiviral medications — particularly oral GS-441524 tablets — hope is now a reality. The Pedersen et al. 2019 UC Davis trial established a 92% success rate when administered correctly.


What Are FIP Tablets?

FIP tablets contain GS-441524, a nucleoside analogue that blocks replication of the FIP virus. Veterinarians and cat owners give these tablets daily, usually for 84 days, depending on the type and severity of the disease. These tablets can treat:


Are FIP Tablets a Cure?

When owners give the correct dosage and complete the full treatment course, most cats recover and return to a normal, healthy life. Several factors affect treatment success:


What Results Can I Expect?

Many cats begin to improve during the first 1–2 weeks. Owners often notice fever decreasing, appetite returning, breathing improving, and energy levels increasing. Read our week-by-week recovery guide for what to expect at each stage. Monitor blood work at days 30, 60, and 84.

After the 84-day treatment, owners should continue a 90-day observation period. If symptoms do not return during this time, the cat is generally considered recovered from FIP.


What If Symptoms Return?

Relapses are rare but can happen. They are often due to underdosing, missed doses, using low-quality or counterfeit tablets, or an incomplete treatment course. Read our FIP relapse guide for what to do if symptoms return. If symptoms return, a second course of treatment may be recommended — usually at a higher dosage.
