What is the dose I need for my pet?
The best way to determine the dose is to ask your veterinarian. If your cat has rhinotracheitis (herpes), you need to use the dose as indicated on the label: 0.5 mg/kg twice daily for 15 days. However, veterinarians may prescribe different doses or use PI in other diseases, for other indications. Your veterinarian will always remain the best source of information. Dr. Alfred Legendre of the University of Tennessee-Knoxville published several papers describing his clinical research with Polyprenyl Immunostimulant™.
How is Polyprenyl Immunostimulant™ administered?
Polyprenyl Immunostimulant™ has been formulated for oral administration. However, your veterinarian may order a different route.
Is Polyprenyl Immunostimulant™ safe?
Yes. You may check more data by clicking here. Safety of Polyprenyl Immunostimulant™ has been tested in 390 cats in 10 states and used for disease control in over 1,000 cats, several dozen ferrets, dogs, birds, and mice. No adverse events were reported.
My cat hates taking PI. Is there anything I can do, such as adding PI to his favorite food?
Most cats will object to taking any medication, or rather anything forced on them against their will. You need to work on your techniques of medication your cat with your veterinarian. PI is tasteless but its smell is recognized as offensive by some cats (albeit we know of two unrelated cats who actually craved PI). Masking the smell helps the process. Many cats agree taking PI in tuna juice. PI is unstable in tuna juice, so you need to get your cat lap it up immediately after mixing.
What if I start my cat on PI and later on it turns out that he/she does not have the disease?
Polyprenyl Immunostimulant™ is safe, and it upregulates innate immunity regardless of the presence of the disease. Your cat will have no problems from the administration of PI. Healthy cats on our safety studies remained healthy.
Can Polyprenyl Immunostimulant™ be combined with other drugs?
You need to ask your veterinarian. Published research by Dr. Alfred Legendre provides information on the use of concurrent drugs.
I think my pet has an adverse response. What do I need to do?
You need to see your veterinarian immediately. If the veterinarian confirms that the adverse event is due to the medication and not to the progression of the disease, you need to file a report with the manufacturer Sass & Sass.

May a veterinarian place an order and let the patient pay for it?
Yes. The order form provides that option. Veterinarians need to fill out the account information and order information sections and let patients complete the shipping information and payment information sections.
My veterinarian has not heard about PI. What information do I need to give him/her?
The best source of information for your veterinarian will be Veterinary Information Network (VIN) to which your veterinarian has an access through professional channels. You may download our package insert and research publications and take to your veterinarian along with the order form.
Do you require prescriptions? Can you fill a prescription?
No. We need to have an order form completed by veterinarians. We are not a pharmacy and cannot fill prescriptions. Veterinarians need to dispense Polyprenyl Immunostimulant™.
How do I order a refill?
Veterinarians need to indicate, in order information section of the order form, if they authorize refills using the same form or send in a separate form with every reorder.
What is the cost of the treatment?
You need to work this out with your veterinarian because the cost to you depends on many factors, including the weight of your pet, dose, and frequency of administration. Some practices may also charge fees. The final cost to you will also depend on the cost of shipping by FedEx. The dose and frequency can be decided by a veterinarian only. In our experience, the cost to owners varies greatly depending on so many factors.
Do you know veterinarians in my area who have used PI?
Most likely, yes. We have worked with many veterinarians and have a locator of veterinarians who have experience with PI. You can find the information by clicking here.
Who distributes Polyprenyl Immunostimulant™ in the US or overseas?

No, we use FedEx only.
What is the cost of shipping?
The cost of shipping depends on the service you select. FedEx allows making easy estimates using their calculator at www.FedEx.com. Here’s the information you need to calculate the cost:
Weight – 1 lb for 1-2 packs of 6 vials
Packaging – FedEx Pak or FedEx Box for Express service, our own packaging for FedEx Ground. FedEx Ground shipping services are available to US customers during the warm seasons only. FedEx Ground may be available to our Canadian customers during warm seasons too.
Shipping from zip code 37830
Added: pickup, insurance for the full value, signature confirmation
Does the package need to be refrigerated?
No. Polyprenyl Immunostimulant™ is stable at temperatures above freezing and does not need to be refrigerated during transit although we recommend storing it in the refrigerator.
It is very hot where I live. Would Polyprenyl Immunostimulant™ get spoiled if the package is left outside until I pick it up?
No. Polyprenyl Immunostimulant™ is stable at temperatures above freezing and would not spoil even at elevated temperatures during transit. However, we would not recommend leaving it outside for prolonged periods of time.
It is very cold where I live. Would Polyprenyl Immunostimulant™ get spoiled if the package is left outside until I pick it up?
Very likely it will. Polyprenyl Immunostimulant™ is unstable at lower temperatures – it should never be frozen therefore. In some areas, we will not allow signature waivers during the cold season to ensure that the product does not get spoiled waiting outside. Freezing breaks fine micelles in the solution, and Polyprenyl Immunostimulant™ may precipitate. It will remain safe but its delivery to the organs will be affected.
May a veterinarian place an order and let the patient pay for it?
Yes. The order form provides that option. Veterinarians need to fill out the account information and order information sections and let patients complete the shipping information and payment information sections..
What type of payments do you accept?
We accept all major credit cards, Paypal, and wire transfers. Orders of $1000 or more require a Credit Card Authorization form to be submitted. Orders of $2500 or more require a wire transfer or equivalent.

No. Care Credit does not allow payments for medicines.
