FIP Treatment Essentials

1. What Should I Feed My Cat During Treatment? Offer freshly cooked fish, chicken, and other natural foods. If your cat experiences diarrhea, consider switching to dry cat food for a few days until the diarrhea subsides.

2. How Long is the Treatment? The recommended treatment duration is 12 weeks. However, the actual length may vary depending on factors such as your cat’s response to treatment, the stage of FIP infection at the onset of treatment, and your personal financial situation.

3. Can GS-441524 Be Used With Other Medications? Yes, GS-441524 is an antiviral treatment that can be used alongside other medications to enhance your cat’s overall health. We suggest combining Nirmatrelvir Tablets with GS-441524. For more details, please check [relevant section/link].

4. Is Interferon Effective for FIP Treatment? Interferon is an immunosuppressant drug that can mitigate symptoms of feline infectious peritonitis (FIP) by dampening the body’s response to the FIPV infection. However, it does not directly treat the virus itself. Thus, Interferon cannot be solely relied upon to cure FIP.

5. What Else Should I Know? As your cat recovers, it will likely gain weight as its appetite returns and regular eating resumes. Monitor your cat’s weight weekly and adjust the dosage accordingly. Collaborate closely with your veterinarian to address potential complications, such as liver and kidney damage or bacterial infections.

Vial Treatment

1. Volume of GS Per Vial? Each vial contains 6ml of the medication.

2. Dosage and Frequency? Administer once daily, based on your cat’s body weight, for 12 weeks.

3. How Do I Determine the Right Dosage? Use our dosage calculator for accurate measurements. Avoid reducing the dosage mid-treatment, as this may lead to increased viral resistance and potential relapse.

4. How Can I Administer the Treatment Myself? Refer to our instructional video for step-by-step guidance on administering subcutaneous injections at home.

5. Storage Recommendations for Vials? For short-term storage (up to 10 days), keep vials at a temperature below 30°C, away from direct sunlight. For long-term storage, refrigerate for up to 3 years. Do not freeze.
