GS-441524 is a nucleoside analogue antiviral compound widely referenced in veterinary medicine and feline infectious peritonitis (FIP) treatment protocols. This injectable formulation provides a liquid preparation intended for veterinary use and offers a practical option when injectable administration is selected as part of a FIP management plan.
The product contains 20mg/ml GS-441524 and is supplied in a 10ml vial. The larger vial format provides additional solution volume for treatment programs that require continued administration and may be convenient for veterinary clinics, animal care organizations, and professional distributors.
FIP is a serious systemic disease associated with feline coronavirus mutation. Depending on the clinical form, affected cats may develop fluid accumulation, inflammation of internal organs, ocular involvement, or neurological symptoms. GS-441524 is incorporated into antiviral treatment protocols because of its activity against viral RNA replication.
The injectable formulation allows administration volume to be calculated according to body weight and the selected veterinary treatment protocol.

Feline infectious peritonitis develops when feline coronavirus mutates and acquires the ability to spread systemically. The resulting disease can affect multiple organs and may present differently depending on the individual cat.
Wet or effusive FIP is generally associated with fluid accumulation in the abdominal or thoracic cavity. Signs can include abdominal enlargement, reduced appetite, lethargy, and breathing difficulties.
Non-effusive FIP may cause inflammatory lesions in internal organs without substantial fluid buildup. Clinical signs vary according to the organs involved.
When the eyes are affected, cats may develop ocular inflammation, changes in eye appearance, or visual disturbances.
Neurological involvement can affect coordination, balance, movement, and other nervous system functions.
Since the clinical presentation of FIP varies, treatment should be based on veterinary examination and continued assessment.

The 20mg/ml concentration provides a consistent amount of GS-441524 in each milliliter of solution. The 10ml vial offers a larger-volume format within the injectable range and can be useful for treatment programs requiring repeated administration.
The liquid dosage form allows treatment volume to be calculated according to the cat's body weight rather than relying on a fixed tablet strength. This can provide additional flexibility when treatment requirements change as the cat gains or loses weight.
Administration should be performed using appropriate sterile procedures and according to veterinary instructions.
The following dosage values correspond to the product information supplied for this formulation:
| FIP Presentation | Reference Volume |
| Wet FIP | 0.3ml/kg body weight + 0.1ml residue |
| Dry FIP | 0.4ml/kg body weight + 0.1ml residue |
| Eye / Neurological FIP | 0.5ml/kg body weight + 0.1ml residue |
| Recurrence Cases | 0.6ml/kg body weight + 0.1ml residue |
These figures should be treated as reference information rather than a universal treatment schedule. A veterinarian should determine the appropriate dosage according to body weight, clinical presentation, response to treatment, and other relevant factors.
The defined 20mg/ml strength provides a consistent concentration for weight-based treatment calculations and routine veterinary use.
The 10ml vial provides a larger-volume option for customers managing ongoing treatment requirements or maintaining veterinary product inventory.
The liquid formulation offers an alternative to oral GS-441524 tablets when a veterinarian determines that injectable administration is appropriate.
The product can be incorporated into veterinary protocols for different FIP presentations, including wet, dry, ocular, neurological, and recurrence cases.
Veterinary professionals may incorporate GS-441524 injection into structured FIP treatment plans while monitoring the cat's body weight, laboratory values, appetite, activity, and clinical condition.
Animal rescue organizations may require injectable antiviral products when caring for cats diagnosed with or being evaluated for FIP under veterinary supervision.
In multi-cat environments, professional veterinary assessment is important when FIP is suspected. Injectable treatment may form part of an appropriate care program.
After veterinary evaluation, some cats continue treatment at home. Caregivers should follow the administration technique, dosage, and schedule provided by the attending veterinarian.
