GS-441524 tablets are an oral form of the antiviral compound GS-441524, widely used in the treatment of Feline Infectious Peritonitis (FIP) in cats. FIP is a fatal disease caused by a mutated feline coronavirus, and GS-441524 has demonstrated strong effectiveness in blocking the replication of this virus in infected felines.
These tablets are typically formulated in specific dosages such as 20mg, 40mg, 50mg, or 60mg, allowing pet owners and veterinarians to conveniently administer the medicine based on the cat’s body weight and FIP type (wet, dry, ocular, or neurological). The oral format offers an easier alternative for cats who may not tolerate injections.

FIP, or Feline Infectious Peritonitis, is a serious and often fatal viral disease that affects cats. It is caused by a mutation of the feline coronavirus (FCoV), a common virus that many cats are exposed to, especially in shelters or multi-cat environments. While most cats infected with feline coronavirus show no or mild symptoms, in rare cases, the virus mutates inside the cat’s body and triggers FIP.
Types of FIP:
Wet (effusive) FIP – Characterized by fluid accumulation in the abdomen or chest, leading to difficulty breathing or a swollen belly.
Dry (non-effusive) FIP – Affects internal organs like the liver, kidneys, eyes, or brain, often causing neurological or ocular symptoms.
Mixed/Neurological/Ocular FIP – Involves a combination of symptoms, including unsteady movement, eye inflammation, or seizures.
Recommended dosage: 10mg/KG * body weight kg
