Phoxilium is used for CRRT (continuous renal replacement therapy) in critically ill patients with ARF (acute renal failure) when pH and kalaemia have been restored to normal and when the patients need phosphate supplementation for loss of phosphate in the ultrafiltrate or to the dialysate during CRRT. Phoxilium may also be used in cases of drug poisoning or intoxications when the poisons are dialysable or pass through the membrane.Phoxilium is indicated for use in patients with normal kalaemia and normal or hypophosphataemia.
