FIP Treatment: What Works Today

Two of them carry current FIP treatment: GS-441524, the gold standard, and molnupiravir, which works through a different mechanism and only exists in oral form. Both are given as a full course and under veterinary supervision.

Yes. These are the forms that demand the most from treatment: they need higher doses than the wet abdominal form and, in neurological cases, sometimes a longer course. The exact dose depends on the clinical presentation and the weight of the cat, and you will find it in the dose calculator. Always confirm it with your vet.

93%. That is the figure held by the two reference registries: CureFIP documents 92.7% and FIPMed 93%. Before 2019, FIP was considered fatal in practically every case.

The response usually begins within 24 to 72 hours. Fever normally settles in the first 24 to 48 hours, red blood cells return to normal around day seven, and ascites disappears visibly within the first 15 days, though it may still show on ultrasound until week four. Most cats behave normally again between weeks two and four.

Daily checks on temperature, weight, appetite, activity and any new clinical sign. On top of that, blood work at the start of treatment and every four weeks, with a complete blood count and biochemistry covering total protein, globulins and albumin.

Relapses mostly appear in the ten days following the end of the course, though they can occur at any point during the observation period. They are treated with a second full course at a higher dose than the first. The success rate of that second course is 96%.
