Polyprenyl Immunostimulant™ FIP Dosage Calculator

How much Polyprenyl Immunostimulant™ do you need for FIP?

Please always work with your veterinarian on all issues related to the treatment of your cat. Our calculator is intended to show you an example based on Dr. Legendre’s extensive research and field trials but it is up to you and your veterinarian to decide how to treat your cat with Polyprenyl Immunostimulant™.

The dose of Polyprenyl Immunostimulant™ depends on the weight of your cat. Dr Legendre recommends 3mg/kg (1.5mL/kg) every other day or three times per week, orally, for Feline Infectious Peritonitis. The single maximum dosage may be adjusted from 5mL to 7.5mL, and the frequency may be adjusted from every other day to daily on a per-case basis. The treatment may be tapered or stopped per your veterinarian’s advice.

Our online Polyprenyl Immunostimulant™ calculator uses Dr. Legendre’s recommendations and gives you an idea of the dosage for the treatment of FIP for your cat. Both calculators allow you to enter your cat’s weight in lb or kg. Please keep in mind that your veterinarian may recommend a different dose/frequency.

Our FIP calculators help you estimate the single dose amount, and how many vials you may need for a two week-period. Per Dr. Legendre, it takes two to three weeks to see the cat’s response. 

Give 3 times per week or more as needed.

How many vials needed for 2 weeks supply

Polyprenyl Immunostimulant™ is formulated as a 2 mg/mL solution of phosphorylated polyprenols and is offered in 10 mL vials or packs of 6 x 10 mL vials.

Polyprenyl Immunostimulant™ reduces the severity of the disease in cats by doing what antivirals cannot accomplish: it restores the cat’s own innate immunity to fight the viral infection. It is a very safe, well-tolerated, easily administered oral liquid designed with cats and their guardians in mind.
