FIP Treatments: FIP Injections vs FIP Tablets or Pills

fip treatments

You may have two alternatives when selecting GS-441524 antiviral medication for FIP treatments: subcutaneous injections or oral capsules or pills. How then do you choose the appropriate one for your cat? We will discuss the advantages and disadvantages of each treatment method in this post, as well as when and how to make the best decision for your cat’s FIP therapy.

Typically, oral medications come in the form of pills. This kind of GS is taken orally. Owners of cats may now choose the best form of treatment for their cat with ease because there are more options accessible. The differences between these 2 GS-441524 formulations will be covered in this post, along with advice on how to pick the best one for your cat’s FIP therapy.

Injection FIP Treatments

Let’s start by discussing the liquid injection version of GS-441524. This particular form of GS is treatable. Different fluids GS-441524 have different properties. The manufacturing technique and chemical quality utilised by the producer have a significant impact on the quality. The fact that prices differ significantly between brands only serves to further compound the uncertainty.

The injectable form of GS441524 comes in various concentrations. The most popular concentrations available now are 20mg and 30 mg. The best way to administer GS-441524 is through injection treatment. Subcutaneous injections of the GS441524 injections immediately treat your cat’s bloodstream with an antiviral medication. Medical practitioners can administer a specific dosage using injections based on the symptoms and body weight of your cat.

Injection-treated cats frequently exhibit obvious changes in as little as one to four days. Therefore, for cats exhibiting severe FIP symptoms, injections are the proper and only effective means of treatment. Every FIP treatment should begin with an injection. Keep administering injections until your cat’s condition has stabilised and only when he or she is eating and eliminating properly should you think about moving to oral medication.

Oral FIP Treatments (Tablets or Pills)

Compared to needles, oral treatment is a quicker and simpler technique to treat FIP. Owners of cats can administer oral medication at home, avoiding daily clinic visits and the expense of injections. Tablets and capsules are available for oral medication. Due to the smooth texture and tastelessness of the capsule, cats can generally swallow capsules more easily than pills. In general, we advise utilising oral capsules or pills in the later stages of treatment, when your cat is no longer in danger, that is, when it is eating and going to the bathroom regularly and no longer has intermittent fevers.

Let’s now discuss the drawbacks of oral therapy. The main difference between oral and injectable treatments is their rate of action. The antiviral medication used in the oral therapy, GS-441524, must pass through the whole digestive tract before entering the bloodstream.

The inability to control dosage is the oral treatment’s second key drawback. We can’t predict how much of the GS-441524 will be absorbed by your cat’s digestive tract, which is why. Your cat may only absorb a percentage of the antiviral medication supplied by the oral capsules, depending on the state of its digestive system and general health. The pace of GS absorption will be impacted by the weakening of the stomach, kidneys, and liver that occurs in cats with feline infectious peritonitis (FIP).

Compared to needles, oral pills and tablets are a riskier form of treatment. Only after 30 days of injection therapy or after your cat’s condition has stabilised do we suggest oral treatment.

A precaution for capsules

In the FIP medication industry, there are certain formats that are predominantly used. For example, GS441524 are predominantly available in tablet form, and EIDD2801 are available in capsule form. So beware of sellers selling GS441524 in capsule format. Also the GS441524 dosage for oral medication is standardised to 15mg per kg and to double the dose for Ocular and Neurological types. Please do not exceed this dosage as the higher dosage in oral medication will compromise the absorbability.

A Comparison between Injection & Oral Treatment

Here is a table that shows the differences between injections and orally taking the treatment for FIP.

Which Method Should I Choose For My Cat?

It is recommended that FIP treatments should begin with injections, per our recommendation. You may transition to oral tablets as soon as your cat’s condition stabilises if recurrent injections cause acute pain or severe skin irritations. After 30 days of injectable treatment, switching to oral medication is typically safe. This is the most trustworthy technique to guarantee that enough GS-441524 is given during the FIP treatment and reduce the risk of reinfection in the future.

Factors influencing oral vs. injection administration

Cats who are currently vomiting/regurgitating and having diarrhoea are generally considered poor candidates for oral GS-441524. As a result, cats suffering from severe gastro-intestinal disease frequently start on injections, at least until the problems are resolved. Most people, particularly in the past, began with injectable GS-441524. The injection form is less expensive, and the dosage is more precisely controlled. Subcutaneous absorption of GS-441524 is also more reliable than oral absorption, which is often a critical factor in the initial treatment of cats who are severely ill and unstable at the start.

Whether a cat continues injecting GS-441524 depends on the owner’s ability to administer injections efficiently, the cat’s willingness to get used to the pain of injection, and the occurrence of injection site sores. In such cases, oral medication is often a welcome relief for both the owner and the feline patient.

Comparison of treatment success with injectable vs oral GS-441524

The success rate with oral GS-441524 now resembles that of injectable versions, assuming dosages are carefully calculated and dosing is performed effectively. However, there have been reports of variations in reactions between the oral and injectable forms of GS-441524. Only a few cats have experienced relapses after switching from injections to oral GS-441524 or have not responded well to it as an initial treatment. Alternatively, illness that was not responding well to injections has been treated by transferring cats to oral GS-441524 at an equivalent dosage.

It is challenging to attribute these stark disparities in response to the medication form because GS-441524 either orally or subcutaneously enters the bloodstream before reaching the tissues. It’s more likely that the injectable or oral GS-441524 brands utilised before this changeover were subpar. In many instances, switching to a different oral or injectable brand resulted in an instant improvement in the reaction.

Because the virus has developed varying degrees of medication resistance, it was thought that only the injectable form of GS-441524 could reach the extraordinarily high blood and cerebrospinal fluid levels required to effectively treat neurological illness. However, cats with neurological FIP have responded well to Fipmed. Additionally, some cats that were not responding to an exceptionally high dosage of the injectable GS- 441524 were also included in this. An all-oral regimen is curing an increasing number of neurological FIP animals. This is either the result of more experience using oral treatment for FIP in challenging cases, or, more likely, the improvement in oral formulation quality.

How do I give the GS injections?

Subcutaneously, sometimes known as “sub-cu,” is a term for giving injections directly beneath the skin. Every day for at least 12 weeks, injections must be given as nearly at the same time every 24 hours. The cat’s muscle should NOT be pierced with the needle. When the GS is injected, it stings, but as soon as the injection is finished, the discomfort stops. Our users have produced a number of useful films demonstrating how they inject, and there are many more on YouTube. It’s better to have your veterinarian administer the first one or two shots and show you how to administer them. A daily visit to the vet may be necessary for cats who are more difficult to restrain for the injections.


As such, cat owners should always start off using the injection method as FIP treatments for their cats and transition to taking pills after around 30 days depending on their cats’ condition. Taking medication via injections or orally taking the medication have their pros and cons and it is up to the veterinarians and cat owners to choose the better solution of the two to provide to FIP affected cats.
