Ask Question

FIP is a serious disease which is caused by a variant of the feline coronavirus (FCoV) , it primarily affects the cat's immune system. It often occurs in young cats or cats with weakened immune systems. It mainly have two types: the wet (effusion-forming) type and the dry (non-effusion-forming) type. If the cat is not be treated, the disease typically progresses rapidly and leads to death.

In the past, FIP was considered an incurable and fatal disease. In recent years, GS441524 and Molnupiravir medicine develop and launch sales, FIP has become effectively controlled and curable. After treatment by GS441 or Molnupiravir, most cats could recover and return to a normal life.

GS-441524 can block viral replication. It is one of the most effective medicine for treating FIP in these years.It is administered by injection Oral tablets, with a course of treatment lasting approximately 6–12 weeks, depending on the cat's weight, symptoms, and response. Molnupiravir also has some effect in treating FIP, and is often used in mild cases or cases resistant to GS-441524.

The absorption of GS441 injection is faster, suitable for cats with severe disease or those who refuse to eat. The oral GS441 tablets are painless. More suitable for long-term home treatment or maintenance. Molnupiravir is an alternative treatment for FIP: suitable for cases of recurrent FIP ​​or those resistant to GS-441524.

The dosage depends on: the cat's weight (kg) and the type of FIP (wet/dry/neurological/ocular). The typical dosage range is approximately 4–10 mg/kg/day. Consult a veterinarian or experienced FIP treatment consultant before treatment.

Some cats may relapse after stopping the medicine, this situation is because of the inadequate treatment or a low dosage. If your cat is relapsed, you need to resume the treatment immediately, and extend the course as appropriate.

If you use it at the correct dosage, GS-441524 is safe. It may have some side effects for some cats, for example: mild redness, swelling, or pain at the injection site. It is recommended to supplement with nutritional supplements, this could help cats recover faster.
