            Warnings

            Contraindications

            Hypersensitivity, hypercalcemia, renal calculi

            Cautions

            Constipation may occur

            Cardiac glycosides; hypercalcemia may aggravate digitalis toxicity

            Advise patients to limit intake of oxalate-rich foods (soy, green leafy vegetables, animal protein) to avoid Ca-Oxalate formation

            Patients with end-stage renal disease may develop hypercalcemia when treated with calcium; avoid concurrent use of calcium supplements, including calcium-based nonprescription antacids

            Early in the treatment phase during dosage adjustment period, monitor

            serum calcium levels twice weekly; should hypercalcemia develop, reduce dosage or discontinue treatment, depending on severity of hypercalcemia

            Severe hypercalcemia (Ca >12 mg/dL) associated with confusion, delirium, stupor, and coma; severe hypercalcemia can be treated by acute hemodialysis and discontinuing therapy

            Mild hypercalcemia (10.5 to 11.9 mg/dL) may be asymptomatic or manifest as constipation, anorexia, nausea, and vomiting; mild hypercalcemia is usually controlled by reducing dose or temporarily discontinuing therapy; decreasing or discontinuing Vitamin D therapy is recommended as well

            Chronic hypercalcemia may lead to vascular calcification and other soft-tissue calcification; radiographic evaluation of suspected anatomical regions may be helpful in early detection of soft tissue calcification; the long-term effect on progression of vascular or soft tissue calcification has not been determined

            Oral solution contains maltitol (1g/5mL) and may induce laxative effect if taken with other products containing maltitol

            Pregnancy & Lactation

            Pregnancy Category: C

            Maintenance of normal serum calcium levels is important for maternal and fetal well being; hypercalcemia during pregnancy may increase risk for maternal and neonatal complications(eg, stillbirth, preterm delivery, neonatal hypocalcemia and hypoparathyroidism);calcium acetate treatment, as recommended, is not expected to harm a fetus if maternal calcium levels are properly monitored during and following treatment

            Lactation: unknown

            Pregnancy Categories

            A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.

            B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk.

            C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done.

            D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk.

            X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist.

            NA: Information not available.

            Pharmacology

            Mechanism of Action

            Chelates phosphate (& other anions, eg, oxalate) in intestine to form insoluble calcium phosphate, which is excreted in feces.

            Pharmacokinetics

            Absorption: 30-40%; however it is the unabsorbed drug that binds and removes phosphate

            Excretion: Feces and urine (20%)

            CALCIUM ACETATE - ORAL

            (KAL-see-um AS-e-tate)

            COMMON BRAND NAME(S): Phoslyra, PhosLo

            USES: Calcium acetate is used to prevent high blood phosphate levels in patients who are on dialysis due to severe kidney disease. Dialysis removes some phosphate from your blood, but it is difficult to remove enough to keep your phosphate levels balanced. Decreasing blood phosphate levels can help keep your bones strong, prevent unsafe buildup of minerals in your body, and possibly decrease the risk of heart disease and strokes that can result from high phosphate levels. Calcium acetate is a natural mineral that works by holding onto phosphate from the diet so that it can pass out of your body.
