Phoslo is a medication used to bind phosphate in the blood and reduce its absorption from the intestines. Its active ingredient, sevelamer carbonate, is a non-absorbable polymer that chemically binds phosphate ions. By forming insoluble complexes with dietary phosphate, the drug prevents the mineral from entering the circulation. This reduction in circulating phosphate helps maintain proper calcium-phosphate balance in patients with chronic kidney disease. The lowered phosphate levels also decrease the stimulus for abnormal calcium deposition in blood vessels and soft tissues. Consequently, Phoslo slows the progression of vascular calcification and supports overall mineral homeostasis in these patients.

Phoslo is a pharmaceutical formulation of phosphate used to supplement serum phosphate levels. It is prescribed to treat hypophosphatemia in patients with chronic kidney disease or other conditions associated with low phosphate. The compound provides exogenous phosphate that is absorbed in the gastrointestinal tract and raises circulating phosphate concentrations. In renal cells the increased phosphate availability stimulates the expression of sodium phosphate cotransporters enhancing phosphate reabsorption. The elevated intracellular phosphate supports cellular metabolism and bone mineralization by providing substrate for atp synthesis and hydroxyapatite formation. Overall Phoslo corrects phosphate deficiency and restores biochemical balance without directly altering hormonal pathways.

Fatigue may be reported by some patients taking Phoslo. Nausea can occur and is usually mild in nature. Abdominal discomfort such as cramping or bloating is another frequently observed effect. Constipation or diarrhea may appear and should be monitored. Some individuals experience mild dizziness or headache. These reactions are generally manageable and do not require medical intervention unless they become severe.

Phoslo may cause constipation in some patients. Nausea is another frequently reported symptom. Headaches can occur, especially during the initial period of treatment. Dizziness or light-headedness may be experienced by some users. Abdominal discomfort such as pain or bloating is possible. Changes in electrolyte levels are occasionally observed. Rarely, skin reactions like rash or itching may develop. Most side effects are mild and often resolve without medical intervention.
