GS-441524 injection support for urgent FIP days.
Facing suspected or diagnosed FIP can feel overwhelming. Start with when injections may be considered, what comes with your order, and the support available along the way.

The FIP shots have made a big difference in my cat’s health. She has been feeling much better, and I’m so thankful to see her improving. I’m grateful for the treatment and the hope it has given us! ❤️🐱
So far all is going on track, vitals are good fluid is draining faster per hospital reports... so I can have him home and start administering ourselves. Ordered 5 vials all received well except for one syringe broken and a box damaged but vials were in tact so no biggy
Hello,
I already very grateful for this medication and the availability. It means everything thing to have my little female cat home with me while treating her for her illness. Also the specialist takes so much stress from this whole nightmare that usually has a very poor prognosis with zero hope. Bunny I know you don't know her but if you did this medicine would be divine intervention just for her...she is the biggest part of my life both her with my other cats her family, my family. So I thank you with all of my heart for your research, your energy that goes into making this medicine available to the public in the USA. My Bunny thanks you too
MaxPaw Health is so great to work with. They are responsive and caring and go out of their way to help ensure I get the medicine my kitty needs. Thank you!

EVERYTHING YOU NEED TO
KNOW ABOUT FIP INJECTIONS
Before your first injection, review the preparation guide below.
Weigh your cat using the most current weight before confirming the daily amount with your veterinarian. Gather the vial, syringe, fresh needle, and cleaning supplies in a calm, quiet space. Confirm needle gauge and length with your veterinarian or advisor. Let the vial reach room temperature, then draw the prescribed dose slowly and tap out any air bubbles.
Gently pinch the scruff of your cat's neck to create a skin tent. Insert the needle at a 45-degree angle. Inject slowly and steadily.
Offer a small treat and gentle praise after each injection. Follow the timing plan confirmed with your veterinarian. Discuss injection-site rotation and skin care with your support contact, and track appetite, energy, weight, fever, and follow-up lab guidance.
Each order includes GS-441524 vials, sterile syringes, and our comprehensive FIP treatment guide.
Our team is available 24/7 for any questions or concerns. You're never alone in this journey.
Questions families ask before buying.
Is this page enough to diagnose FIP?
No. Symptoms can suggest FIP, but diagnosis should be made with a veterinarian using exam findings, history, lab work, imaging, and other clinical evidence.
What comes with the injection order?
The kit includes GS-441524 vials, 3cc syringes with needles, and guidance materials so families are not searching for basic supplies separately.
Do injections have to happen at the same time every day?
Consistency is commonly emphasized in FIP treatment routines. Confirm your timing plan with your veterinarian or treatment support contact.
Should GS-441524 be refrigerated?
Refrigeration is not required. Keep the vial away from heat and light, and follow the storage instructions on your product label.
