Generally very well tolerated
Rare mild gastrointestinal upset (vomiting or soft stool) may occur, especially when starting treatment

In chronic kidney disease, failing kidneys can no longer excrete phosphorus properly. High phosphorus levels accelerate kidney damage and contribute to nausea, weakness, and bone issues. Using Fosrenol as part of a comprehensive renal care plan (alongside diet and fluids) is one of the most evidence-based ways to extend both lifespan and comfort in feline CKD patients.
