Feline Infectious Peritonitis (FIP) continues to be one of the most concerning diagnoses for Filipino cat owners. While GS-441524 remains the gold standard treatment, its cost can be difficult for many families—especially for owners caring for rescued strays, adopted community cats, or multiple pets.

This growing need for affordable yet effective treatment options has led to the rise of Molnupiravir-based therapies, particularly the active compound EIDD-1931, formulated as MolnuFIP™ for feline use.

Although human Molnupiravir (EIDD-2801) was developed for people, MolnuFIP™ offers stronger antiviral action, better safety, and improved consistency for cats battling FIP.
What Is EIDD-1931 (MolnuFIP™)?
EIDD-1931 is the active antiviral molecule responsible for Molnupiravir’s effect. Human Molnupiravir (EIDD-2801) must first be converted by the liver into EIDD-1931 before it becomes functional. Cats do not convert the medication efficiently, making EIDD-1931—the active form—far more suitable.
Advantages of Using Pure EIDD-1931:
Quicker activation
Greater antiviral potency
More reliable clinical outcomes
Current studies indicate EIDD-1931 is 4.4 times stronger than human Molnupiravir and shows about 97% treatment success for wet and dry FIP when properly administered.
Why Filipino Cat Owners Are Choosing EIDD-1931 (MolnuFIP™)
1. Created Specifically for Cats
MolnuFIP™ is engineered for feline physiology, giving it faster and more targeted antiviral action.
2. Strong and Consistent Results
Because the compound is already active, it starts working immediately—helping stabilize symptoms faster.
3. Easy-to-Give Oral Soft Gel
A big challenge for many Filipino pet owners is giving medication, especially to anxious or picky cats. MolnuFIP™ soft gels are:
Tasteless
Easy to swallow
Can be mixed with food
4. No Known Resistance
There is currently no documented FIP viral resistance to EIDD-1931.
5. Fast Improvement Noted by PH Owners
Most Filipino users report visible improvement—appetite, activity, temperature—within 5–7 days of starting treatment.

Frequently Asked Questions
Is MolnuFIP™ the same as human Molnupiravir?
No. MolnuFIP™ uses EIDD-1931, an active compound specifically formulated for feline use, not the human Molnupiravir (EIDD-2801).
Is it safe for long-term use?
MolnuFIP™ should be used for a minimum of 30 days and a maximum of 60 days. It is not recommended to exceed 60 days, as prolonged use may cause mild effects on the liver or kidneys, and potential long term side effects due to the mutagenic nature of the medication.

It is effective for both wet and dry FIP. However, it is not recommended for ocular or neurological FIP, and not suitable for cats with existing kidney issues.
Is it more affordable?
Yes, MolnuFIP™ offers an accessible treatment option for cat owners seeking effective and high-quality FIP care.
How is it administered?
Given orally — either directly or mixed with food once every 12 hours. It is tasteless and easy for cats to ingest.
Where can I purchase authentic MolnuFIP™ products?
