Injectable GS-441524 for FIP treatment in cats
The Lanzi vial contains GS-441524 at 17 mg/ml, the antiviral with the highest proven efficacy rate against feline FIP. Being injectable, the active ingredient is absorbed directly without depending on the cat’s digestive state, making it especially effective during the most critical phase of treatment.
More than 80% of cats treated with GS-441524 achieve sustained remission in wet FIP with a complete 84-day protocol.
The key to achieving this result is to start with the correct dose from day one and not interrupt the treatment.
Injectable or Pills?
Choose injectable if…
- Your cat is severely ill

- Your cat still eats and is active but has diarrhea
Switch to pills when…
- Your cat is out of danger
- There is a clear improvement in their appetite and activity
- There is no diarrhea or vomiting
- Digestion is stable and they tolerate oral medication well
If you have doubts about when to make the switch, we are available to guide you.
How to administer it
- Subcutaneous injection every 24 hours, always at the same time

How many vials do you need?
