As adjunctive therapy in the management of acute symptoms in lead colic. In the treatment of magnesium intoxication due to overdosage of magnesium sulfate.

About this medicine
DESCRIPTION Calcium Chloride Injection, USP, 10%, is a sterile aqueous solution containing, in each mL, 100 mg (1.36 mEq) calcium chloride. The pH of the solution may have been adjusted with hydrochloric acid and / or calcium hydroxide, when necessary. The air above the liquid in the individual containers has been displaced by flushing with nitrogen during the filling operation. The preparation contains no antimicrobial preservatives and is intended as a single-dose vial; once the unit is assembled and used, any remaining portion of the solution must be discarded with the entire unit. Calcium Chloride, USP, contains two molecules of water of hydration and is chemically designated as CaCl 2 • 2H 2 0.
Who should not take it
CONTRAINDICATIONS Calcium chloride is contraindicated for cardiac resuscitation in the presence of ventricular fibrillation.
Warnings
WARNINGS Calcium chloride should be injected into a large vein very slowly, as it may cause peripheral vasodilatation and a cutaneous burning sensation. A moderate fall in blood pressure due to vasodilatation may attend the injection. Since calcium chloride is an acidifying salt, it is usually undesirable in the treatment of hypocalcemia or renal insufficiency.
Reported side effects
ADVERSE REACTIONS Rapid I.V. injection may cause the patient to complain of tingling sensations, a calcium taste, a sense of oppression or “heat wave.” Injections of calcium chloride are accompanied by peripheral vasodilation as well as a local “burning” sensation, and there may be a moderate fall in blood pressure.
Interactions with other medicines
Drug Interactions Because of the danger involved in the 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 the indications are clearly defined. Calcium salts should not generally be mixed with carbonates, phosphates, sulfates or tartrates in parenteral admixtures.
