DESCRIPTIONCalcium Gluconate is the calcium salt of gluconic acid, an oxidation product of glucose, and contains 9.3% calcium, which is about one-third of the calcium in strength of calcium chloride USP. Since it is soluble to the extent of only one part in 30 parts of cold water, the 10% solution is supersaturated and is stabilized by the addition of calcium saccharate tetrahydrate 0.46% w/v (which supplies calcium 6.2%). Each mL contains 98 mg of calcium gluconatemonohydrate, 4.6 mg of calcium saccharate tetrahydrate, and Water for Injection USP, q.s. Each mL provides 9.3 mg (0.465 milliequivalents) of calcium.The 100 mL Pharmacy Bulk Package contains many single doses for use in a pharmacy admixture program in the preparation of parenteral fluids. See directions for dispensing from the 100 mL Pharmacy Bulk Package. pH is adjusted with sodium hydroxide and/or hydrochloric acid.The structural formula is:C12H22CaO14..........................430.38 Indications INDICATIONS Calcium gluconate is used to treat conditions arising from calcium deficiencies such as hypocalcemic tetany, hypocalcemia related to hypoparathyrodism and hypocalcemia due to rapid growth or pregnancy. It is also used in the treatment of black widow spider bites to relieve muscle cramping and as an adjunct in the treatment of rickets, osteomalacia, lead colic and magnesium sulfate overdosage. Calcium gluconate has also been employed to decrease capillary permeability in allergic conditions, nonthrombocytopenic purpura and exudative dermatoses such as dermatitis herpetiformis and for pruritus of eruptions caused by certain drugs. In hyperkalemia, calcium gluconate may aid in antagonizing the cardiac toxicity provided the patient is not receiving digitalis therapy. Dosage DOSAGE AND ADMINISTRATION Calcium Gluconate should be administered intravenously either directly or by infusion. The dose is dependent upon the individual requirements of the patient. Calcium Gluconate may also be administered by intermittent infusion at a rate not exceeding 200 mg/min, or by continuous infusion. DIRECTIONS FOR DISPENSING FROM 100 mL PHARMACY BULK PACKAGE - NOT FOR DIRECT INFUSION. The 100 mL Pharmacy Bulk Package is for use in a Pharmacy Admixture Service only.

Rev: 2/00 Side Effects SIDE EFFECTS Patients may complain of tingling sensations, a sense of oppression or heat waves and a calcium or chalky taste following the intravenous administration of calcium gluconate. Rapid intravenous injection of calcium salts may cause vasodilation, decreased blood pressure, bradycardia, cardiac arrhythmias, syncope and cardiac arrest. Use in digitalized patients may precipitate arrhythmias. Local necrosis and abscess formation may occur with intramuscular injection. Drug Interactions DRUG INTERACTIONS The ionotropic and toxic effects of cardiac glycosides and calcium are synergistic and arrhythmias may occur if these drugs are given together (particularly when calcium is given intravenously). Intravenous administration of calcium should be avoided in patients receiving cardiac glycosides; if necessary, calcium should be given slowly in small amounts. Calcium complexes tetracycline antibiotics rendering them inactive. The two drugs should not be given at the same time orally nor should they be mixed for parenteral administration. Calcium Gluconate Injection has been reported to be incompatible with intravenous solutions containing various drugs. Published data are too varied and/or limited to permit generalizations, and specialized references should be consulted for specific information. Drug/Laboratory Test Interactions Transient elevations of plasma 11-hydroxy-corticosteroid levels (Glenn-Nelson technique) may occur when intravenous calcium is administered, but levels return to control values after one hour. In addition, intravenous calcium gluconate can produce false-negative values for serum and urinary magnesium. Warnings WARNINGS For intravenous use only. Subcutaneous or intramuscular injection may cause severe necrosis and sloughing. This product contains aluminum that may be toxic. Aluminum may reach toxic levels with prolonged parenteral administration if kidney function is impaired. Premature neonates are particularly at risk because their kidneys are immature, and they require large amounts of calcium and phosphate solutions, which contain aluminum. Research indicates that patients with impaired kidney function, including premature neonates, who receive parenteral levels of aluminum at greater than 4 to 5 mcg/kg/day accumulate aluminum at levels associated with central nervous system and bone toxicity. Tissue loading may occur at even lower rates of administration. Precautions PRECAUTIONS General To avoid undesirable reactions that may follow rapid intravenous administration of calcium gluconate, the drug should be given slowly, e.g., approximately 1.5 mL over a period of one minute. When injected intravenously, calcium gluconate should be injected through a small needle into a large vein in order to avoid too rapid increase in serum calcium and extravasation of calcium solution into the surrounding tissue with resultant necrosis. Rapid injection of calcium gluconate may cause vasodilation decreased blood pressure, bradycardia, cardiac arrhythmias, syncope and cardiac arrest. Because of the danger involved in simultaneous use of calcium salts and drugs of the digitalis group, a digitalized patient should not receive an intravenous injection of a calcium compound unless indications are clearly defined. Pregnancy Category C Animal reproduction studies have not been conducted with calcium gluconate. It is also not known whether calcium gluconate can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. Calcium gluconate should be given to a pregnant woman only if clearly needed. Nursing Mothers It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when calcium gluconate is administered to a nursing woman. Overdosage & Contraindications OVERDOSE No information provided. CONTRAINDICATIONS Calcium salts are contraindicated in patients with ventricular fibrillation or hypercalcemia. Intravenous administration of calcium is contraindicated when serum calcium levels are above normal. Clinical Pharmacology CLINICAL PHARMACOLOGY Calcium is the fifth most abundant element in the body and is essential for maintenance of the functional integrity of nervous, muscular and skeletal systems and cell membrane and capillary permeability. It is also an important activator in many enzymatic reactions and is essential to a number of physiologic processes including transmission of nerve impulses; contraction of cardiac, smooth and skeletal muscles; renal function; respiration and blood coagulation. Calcium also plays regulatory roles in the release and storage of neurotransmitters and hormones, in the uptake and binding of amino acids, and in cyanocobalamin (vitamin B12) absorption and gastrin secretion.
