EIDD-1931 Oral Capsules - FIP and FCV treatment
Choose Cat's Body Weight
Our capsules deliver pure EIDD-1931, the active antiviral metabolite of molnupiravir, in a formulation designed exclusively for feline physiology. By using EIDD-1931 directly—rather than modifying human molnupiravir capsules—EIDD-1931 provides a more precise, consistent, and veterinary-appropriate approach to FIP care.
Purpose-Built Feline Formulation
Each EIDD-1931 capsule contains 15 mg of EIDD-1931, equivalent in activity to approximately 66 mg of molnupiravir (EIDD-2801).
This formulation is optimized for:
Feline metabolic rate
Gastrointestinal absorption profile
Reliable dose–response performance
The result is accurate, predictable antiviral activity with reduced variability compared to human-intended products.
Proven Antiviral Potency
Published research demonstrates that:
EIDD-1931 exhibits up to 5.6× greater in-vitro antiviral potency compared with molnupiravir (EIDD-2801).
EIDD-1931 demonstrates 7.3× higher potency than GS-441524 under similar test conditions.
This potency advantage enables therapeutic efficacy at lower milligram doses, supporting improved tolerability and rapid clinical response.

Dosage Instruction
Dosage Instructions
Administer one (1) capsule per 2.5 kg of body weight, given every 12 hours.
Dosing Examples
Example 1: A 2.0 kg kitten diagnosed with the effusive (wet) form of FIP should receive one capsule every 12 hours.
Example 2: A 4.6 kg adult cat diagnosed with the non-effusive (dry) form of FIP should receive two capsules every 12 hours.
Monitoring and Follow-Up
