Calculate the recommended GS-441524 dose for your cat based on weight, FIP presentation, and treatment protocol.
GS-441524 Dosing Calculator
Our GS-441524 Dosing Calculator is a free online tool designed to help determine the recommended GS-441524 dosing based on your catʼs weight and condition. It is specifically intended for use with Aino GS-441524 injectables and tablets, providing simple and convienient dosing guidance for both veterinarians and cat parents
Recommended daily dose
Important notes
- Tablet dosage is +2mg/kg from injection dosages. Change of route lowers bioavailability.
- Always round the tablet dose up to the nearest achievable tablet split. (see Tablet Strength Reference Guide) Multiple tablet splits can be combined to achieve the most accurate dose
Dosage Reference Guide
The values displayed are the recommended minimum starting doses. Actual doses may vary based on your veterinarian’s assessment and your cat’s clinical response
| FIP Type / Condition | Injectable 84 days |
Injectable / Oral 42 days |
|---|---|---|
| Wet FIP (abdominal effusion) & Dry FIP (mild symptoms) |
6 mg/kg | 15 mg/kg |
| Wet FIP (pleural effusion) & Dry FIP (severe symptoms) |
8 mg/kg | 15 mg/kg |
| Severe Anemia | 10 mg/kg | 15 mg/kg |
| Ocular FIP | 10 mg/kg | 15-20 mg/kg |
| Neurological FIP | 10-15 mg/kg | 15-20 mg/kg |
- 15 mg/kg is the minimum starting dose for both injectable and oral GS-441524 in a 42-day protocol.
- For the 42-day protocol, injections and tablets typically start at the same recommended dose. However, if the treatment route is changed after therapy has begun, the standard +2 mg/kg adjustment should still be applied when switching from injections to tablet
- For the 42-day protocol, injections and tablets typically start at the same recommended dose. However, if the treatment route is changed after therapy has begun, the standard +2 mg/kg adjustment should still be applied when switching from injections to tablet
- If clinical signs persist or bloodwork has not normalized, treatment is usually extended toward the standard 84-day protocol rather than stopped.
| Tablet Strength | How to Cut | Resulting Dose |
|---|---|---|
| 25 mg | ½ tablet | 12.5 mg |
| 50 mg | ½ tablet | 25 mg |
| 50 mg | ¼ tablet | 12.5 mg |
- Do not attempt to cut 25 mg tablets into quarters, as accurate dosing may become unreliable.
- Always use a pill cutter for best accuracy and follow your veterinarianʼs dosing instructions.
Frequently Asked Questions
How accurate is the dosing calculator?
The calculator provides dosing recommendations based on your cat’s weight, the selected treatment protocol, and current GS-441524 dosing guidelines. It is intended as a guide and should not replace veterinary advice.
Does the calculator replace my veterinarian's instructions?
No. Every cat responds differently to treatment. Your veterinarian or FIP treatment advisor may recommend dose adjustments based on your cat’s clinical signs, bloodwork, or treatment progress.
Why does the tablet dose differ from the injectable dose?
Oral GS-441524 is absorbed differently than injectable GS-441524. For the standard 84-day treatment protocol, tablet doses are generally 2 mg/kg higher than injectable doses to compensate for the lower oral bioavailability.
Why doesn't the 42-day protocol add 2 mg/kg to the tablet dose?
For the 42-day protocol, both injections and tablets typically begin at the same recommended starting dose. If your cat switches from injections to tablets after treatment has started, the standard +2 mg/kg adjustment should still be applied.
Should I round the calculated tablet dose?
Yes. Always round the calculated tablet dose up to the nearest achievable tablet split. Multiple tablet pieces may be combined to achieve the closest practical dose.
Can I cut the tablets into quarters?
Our 50 mg tablets can be divided into halves or quarters if needed. However, 25 mg tablets should not be cut into quarters, as this may result in inaccurate dosing.
Which weight should I use?
Use your cat’s current body weight. Since many cats gain weight during treatment, weigh your cat regularly and recalculate the dose whenever their weight changes.
How often should I recalculate the dose?
Recalculate the dose whenever your cat gains weight or your veterinarian recommends a dosage adjustment. Maintaining the correct mg/kg dose throughout treatment is important.
Does the calculator tell me how much to inject?
Yes. For injectable GS-441524, the calculator converts the recommended dose into the appropriate milliliter (mL) volume based on Aino’s 20 mg/mL concentration.
Can I use this calculator with other GS-441524 brands?
The injectable calculator is designed specifically for Aino GS-441524 20 mg/mL. If you are using another brand with a different concentration, the calculated injection volume will not be accurate. The mg/kg dose remains the same, but the mL volume must be calculated using your product’s concentration.
What if my cat has neurological or ocular FIP?
Neurological and ocular FIP often require higher doses than uncomplicated wet or dry FIP. Select the appropriate disease presentation in the calculator to receive the recommended starting dose.
Is this calculator suitable for both the 84-day and 42-day protocols?
Yes. The calculator supports both treatment protocols. Be sure to select the correct protocol before calculating the dose.
My calculated dose is different from what my veterinarian prescribed. Which should I follow?
Always follow the guidance of your veterinarian or FIP treatment advisor. The calculator provides evidence-based starting recommendations, but individual cats may require higher or lower doses depending on their condition, response to treatment, and laboratory results.
