What is the recommended GS-441524 dosage for cats with wet FIP?

The standard clinical dosage of GS-441524 for cats with wet (effusive) FIP is 6.0 mg per kilogram of body weight, administered once every 24 hours via subcutaneous injection or oral capsules for 84 consecutive days.

What is the GS-441524 dosage for dry, ocular, and neurological FIP?

For dry FIP (non-effusive), the standard dosage is 8.0 mg/kg daily. For ocular FIP with uveitis, the dosage is 10.0 mg/kg daily. For neurological FIP with ataxia or tremors, the dosage is 10.0 to 12.0 mg/kg daily to penetrate the blood-brain barrier.

Why is the FIP treatment protocol 84 days long?

Clinical studies by Dr. Niels Pedersen at UC Davis demonstrated that 84 continuous days (12 weeks) are required to eliminate all replicating viral reservoirs in deep tissues and macrophages, preventing post-treatment relapse.

Can cats transition from FIP injections to oral pills?

Yes, cats can safely transition to oral GS-441524 capsules after 14 to 30 days of injections once their appetite has fully normalized, fever has cleared, and abdominal or pleural effusion is completely reabsorbed.
