CureFIP™ GS-441524 Injectable 20mg/ml
 
Precision Dosing Formulation for Small and Underweight Cats
 
CureFIP™ GS-441524 20mg/ml is the lowest-concentration injectable in our range, developed specifically for FIP treatment in cats weighing less than 2.5 kg. A lower concentration does not mean lower efficacy. The total dose of GS-441524 delivered (mg/kg body weight) is identical to the 30mg/ml and 40mg/ml formulations. The reason to choose 20mg/ml is singular: precision.
 
Why 20mg/ml?
FIP treatment dosing is determined by mg of GS-441524 per kg of body weight. When a high-concentration formulation is used in very low-weight cats, the volume required for a single dose becomes extremely small — making accurate measurement difficult or clinically unreliable. Measurement error results in underdosing or overdosing, both of which directly affect treatment outcomes.
 
The 20mg/ml format resolves this for cats weighing less than 2.5 kg:
Minimises measurement error
Reduces injection site irritation from excessive volume concentration
Ensures accurate GS-441524 delivery at every dose
 
Indicated Cases
Small adult cats weighing under 2.5 kg
Kittens diagnosed with FIP
Cases where precise measurement with high-concentration formulations is compromised by low body weight
Cases requiring concentration adjustment due to weight loss during treatment

Administration Protocol
 
Standard 84-day protocol applies. Dose is calculated based on mg of GS-441524 per kg body weight. The calculation principle is identical regardless of concentration used. Use the dosing calculator to determine the precise dose for your cat's weight.
If additional nutritional support is required — particularly for anaemic cats or cases with neurological involvement — consider the CureFIP™ GS-441524 + B12 20mg/ml formulation.
