FIP Recovery with Oral Tablets: What to Expect Week by Week

FIP recovery begins the moment you start treatment with oral GS-441524 tablets. While the full course lasts 84 days, each week brings visible improvements and important milestones. By understanding this timeline, you can monitor progress more effectively and detect any issues early. Read our complete blood work guide to understand what each marker means at each stage.

After Treatment: Observation Period

After completing treatment, your cat enters a 90-day observation phase without medication. During this period, watch for lethargy, fever, loss of appetite, swelling, or neurological symptoms. If any of these symptoms appear, contact FIP Cure Plus immediately. Early action can prevent relapse and protect your cat’s recovery.
