GS‑441524 Tablets are an advanced oral formulation developed specifically for the treatment of Feline Infectious Peritonitis (FIP) in cats. Made with ≥99.5% pure GS‑441524, these tablets offer a reliable, non-invasive alternative to injectable therapies. They are designed to provide accurate dosing based on the cat’s body weight, making treatment both effective and convenient for pet owners and caregivers.
Each dosage strength corresponds to a target weight:
40mg tablets for cats weighing approximately 2.5kg-4kg
50mg tablets for cats around 5kg
60mg tablets for cats near 6kg
This simplified approach ensures correct dosing for various stages and types of FIP, including wet (effusive), dry (non-effusive), and even neurological or ocular forms. The tablets are easy to administer and ideal for home-based care, especially for cats that are sensitive to injections.
With rapid absorption and high bioavailability, GS‑441524 Tablets begin working within days, often leading to noticeable improvement in appetite, energy, and overall behavior. When used consistently over a standard 84-day course, the tablets have shown high success rates in global case studies.

Feline Infectious Peritonitis (FIP) is a fatal viral disease in cats caused by a mutation of the feline coronavirus (FCoV). While most cats infected with FCoV do not develop FIP, in some cases, the virus mutates and triggers an abnormal immune response, leading to FIP.
FCoV is common in multi-cat environments like shelters and catteries. The virus is primarily transmitted through fecal-oral contact, where cats ingest the virus from contaminated surfaces, litter boxes, or grooming each other.
