When can I start oral capsule treatment for my cat?

For  best treatment results, use oral capsules after 30 days of vials treatment or after your cat’s condition has stabilized, eating and pooping normally, and doesn’t display any neurological symptoms.


When not to use oral capsules?  

While your cat still exhibits ocular or neurological symptoms or suffers from intermittent vomiting or diarrhoea. If the cat is not eating and requires force-feeding or subcutaneous (SQ) fluid administration.


How to choose the right type of oral capsule for my cat?

Choose the oral capsules according to your cat’s current weight (Every 10mg for 1kg of cat’s weight)


1kg – 1 quarter of 40mg tablet per day

2kg – Half of 40mg tablet per day

3kg – 1 tablet of 30mg per day

4kg – 1 tablet of 40mg per day


(Please round up to the nearerst kg)


How many times should I feed the medicine to my cat?

1 time a day, at regular intervals. Do not skip any day. Continue until 84 days or when all FIP symptoms have disappeared.


What should I do if my cat gained weight but the oral capsule that I purchased before is for cats that is below my cat’s current weight?

You should switch to the higher concentration of the oral capsule for your cat’s new weight. For example, if your cat’s weight has increased from 2.4kg to 2.8kg, it is recommended to increase the dosage to suit 2.8kg. This ensures that your cat is provided with sufficient active pharmaceutical ingredients for its treatment.


How many tablets do 1 strip of tablets contain?

One strip contains 10 tablets.


What should I do if my cat does not show improvement after using oral capsules?   Can I give him two pills per day?

Lack of improvement or deteriorating conditions are caused by either insufficient dosage or poor absorption by your cat’s digestive system. You should provide at least 5 days of oral capsules before determining whether there is a lack of improvement. After 5 days if there is no visible improvement of symptoms, you may increase dosage from 1 oral capsule to 2 oral capsules per day, or switch to a higher concentration of oral capsule. The best option is to  switch to vials. Vials are the most reliable method of delivering an appropriate dose of active pharmaceutical ingredients to your cat’s body.


How do I know the amount of GS that my cat will absorb?

Each cat has a different absorption rate for the oral capsule, based on genetics and health factors. The exact absorption can only be determined via a complex and expensive diagnostic procedure called HPLC analysis.


Is Oral capsules a better choice compared to Vials?

Each treatment option has its pros and cons. Both treatment options are effective against feline infectious peritonitis (FIP) infections. Vials are precise and more not subjected to absorption issues. The effects are immediate. We recommend starting all feline infectious peritonitis (FIP) treatments with vials. Oral capsules are easier to administer, cause no pain, and can be done easily at home. However, GS-441524 will take longer to travel to the bloodstream because it first has to go through the digestive system. It is also impossible to know how much of the GS-441524 is absorbed by the body to combat FIPV. We recommend starting oral capsules treatment only after your cat’s condition is stable. Feline infectious peritonitis virus often damages digestive organs such as the stomach, intestines, kidneys and liver as it spreads throughout the body. Damaged organs reduce digestive functions and will cause poor absorption of FipMed into the bloodstream.  When oral capsules are given too early in the treatment, it may cause prolonged treatment or higher chances of relapse in the future.

Can I switch back vials treatment after I started oral capsule treatment?

You may switch back to vials after starting oral capsule treatment. However the vial dosage will start from 10mg/kg after you switch from oral to vial. This is because our oral capsule has higher concentration than vial treatment. Please consult us the vial amount for your cat if you wish to switch from oral to vial treatment.


My cat has relapsed, can I use oral capsules to treat him/her?

We do not recommend using oral capsules for relapsed cases. You should use vials and provide between 12mg-15mg for relapse treatments. Please consult us on how to properly treat relapsed FIP cases.


How long does it take for my cat to show improvement?

Normally cats will show improvement within 10-15 days of oral  treatment. Some cats will show improvement within as little as 5 days.


Why is oral treatment more expensive than vials?

Oral capsules require higher concentration of the active pharmaceutical ingredient GS-441524 to treat FIPV when compared to vials. Production of oral capsules is also more complex and time consuming compared to vial. These factors caused the price of oral capsules to be higher than vial.


Are there any side effects when using FipMed oral capsule treatment?

There are no known side effects when using our oral capsule.  You may use it in conjunction with other treatments and supplements recommended by your veterinarian.


What if I cannot feed my cat oral capsule daily at the same time every day?

For best results the oral treatment should be administered within a 3 hour window from the time of the previous day, 1.5 hours before or 1.5 hours after the previous day.


Can I return unused capsules for a refund?

We do not accept opened and/or partially consumed oral capsule packages. We recommend donate unused oral capsules to your veterinarian or other FIP cat owners so they may use the capsules to help save cats.

My sweet boy Bert is 5 1/2 years old and has been diagnosed with wet FIP. It came about quickly. I quickly ordered these pills and somehow it is effective and slowly working for Bert. Let’s hope for Bert’s speedy recovery!

Cashew, my FIP boy, was literally days from passing before I was able to get him treatment. He needed IV fluids and nutrition, as well as round the clock care from a vet, to pull him through the first week. We were *extremely* lucky to be connected with a vet willing to help and knowledgable about FIP. It was still touch and go.

Cashew was, at the time, a foster kitten. The rescue we fostered with wasn’t sure about the diagnosis, and then wasnt sure about treatment (since its not officially recognized), and then thought he was too sick. Finally, my partner and I legally took over the care of Cashew and his brother Walnut, so we could get them treatment.

Even if your baby is very ill, there is hope. Cashew has 14 days left in treatment, and is healthy, happy, and strong. He was just 3.5 months old when we started treatment.
